Capi Money

Capi is building the financial infrastructure for emerging markets trade. Backed by $18M+ from top-tier investors like Creandum, Y Combinator, General Catalyst, and angels from Revolut, Checkout, Stripe, and Remitly, we’re building the financial infrastructure that emerging markets deserve. Our mission is to grow GDP in emerging markets by making the global financial system fairer and more accessible. We’re tackling global trade, making it easier for importers to pay their international suppliers. Our platform enables businesses to expand rapidly, create jobs, and be engines of prosperity for their countries. Our team is made up of approx 100 people across 10 countries; we are a group of a highly-ambitious, get-it-done people, who like to work hard on something that has a tangible impact in the world. And we’re looking for more people to join our team! Take a look through Capi’s mission & values. ROLE OVERVIEW You'll join a small, high-performing team of engineers and product leaders shaping how we scale our platform and our impact. From your first day, you will have the opportunity to work closely with the founding team based across London & Paris to shape the product vision and all parts of our technical architecture. As we scale our products and deepen our presence across emerging markets, this is a role that builds technology to solve customer problems. To do that, you must have empathy and curiosity to get to the root cause of the issue and the creativity to build a solution that balances impact, effort, and delight. KEY RESPONSIBILITIES Leadership Excellence * Lead by technical example — your influence comes from the quality of your work, your judgment and your ability to bring others along with you, not from authority. * Own technical direction within your team and workstream, collaborating closely with principal engineers and the Head of Engineering to align with broader architectural strategy. * Mentor senior engineers through pairing, code reviews and design discussions — raising the technical floor of the people around you. * Champion engineering best practices across the team, introducing standards and patterns that improve consistency, reliability and developer experience. * Act as a subject matter expert in your core technical domain, and be the person others turn to when the problem is hard. Delivery Excellence * Lead the end-to-end delivery of complex, multi-stakeholder projects — from scoping and design through to deployment, feedback and iteration. * Translate ambiguous problem spaces into clear technical plans, breaking down large initiatives into well-defined milestones that the team can execute against. * Manage delivery dependencies across teams and communicate progress clearly to both technical and non-technical stakeholders. * Drive a culture of outcome-oriented delivery within your workstream — focused on impact shipped, not activity completed. * Proactively identify and remove blockers before they slow the team down. Operational Excellence * Take ownership of the reliability and observability of systems within your domain — ensuring they are monitored, well-understood and resilient to failure. * Handle production incidents with confidence, leading postmortems that result in genuine process improvements rather than just documentation. * Set the standard for what good operational practice looks like within your team — monitoring, alerting, runbooks and on-call hygiene. * Contribute to company-wide reliability initiatives led by principal engineers and the Head of Engineering. Technical Excellence * Make and defend strong architectural decisions within your workstream, balancing pragmatism with long-term technical health. * Write production-quality code consistently — this is a fully IC role and hands-on technical contribution is expected at all times. * Drive scalability, modularity and performance improvements in the areas of the codebase you own. * Champion code quality through rigorous testing, thoughtful documentation and constructive code reviews that develop the engineers around you. * Proactively identify technical debt and lead initiatives to address it before it compounds. Culture Communicate internally and externally about new features, be it collecting feedback pre-implementation or explaining them on launch. REQUIREMENTS Our tech stack: Typescript, React, NextJS, NodeJS, Express, PostgreSQL * A product mindset is core to how we build - everyone at Capi is encouraged to think about the customer, the business, and the long-term impact of what we ship. * A strong understanding of web development, frontend and backend best practices. While mainly working with JavaScript technologies. * Experience in a VC-backed or high-growth engineering team and building products used by customers. * You are comfortable working in an early-stage startup environment with high pace, rapid growth, involvement in the entire product development process, and a high degree of ambiguity. * Excellent written and verbal communication skills for expressing ideas, designs, and potential solutions with both technical and non-technical team members and customers. * You care about our mission and solving the problems faced by African businesses. * Based in London or Paris. Bonus points if you: * Speak and write in French & English * Experience in Fintech, payments, wallets or building ledgers * Expertise in security and data protection best practices needed in a FCA regulated business Some projects the team has been working on: * Automated payouts and AI invoice approval * Onboarding + payment automation with Swift network and banking partners across the world * WhatsApp bot that creates quotes for customers based on their responses * Self-serve onboarding flow that collects company information and KYC documents from customers * Asynchronous workers that OCR invoices * Internal tooling to manage and process millions of dollars of transactions WHAT TO EXPECT WHEN INTERVIEWING WITH CAPI?

Joko

At Joko, we help consumers shop smarter. Our mission is to revolutionize shopping, empowering people to find what they need, make informed decisions, and save money. Founded in Paris, Joko is a tech company and certified B Corp with over 105 talents across Paris, Barcelona, and New York (and beyond). More than 6 million users already save money every day at 10,000+ merchants with Joko. From cashback and automatic coupons to price alerts and carbon tracking, we keep expanding our products to make shopping smarter. We’re now building an AI-powered shopping assistant to help users find the best products by price, quality, and environmental impact. Having reached profitability in our core market, we’re now scaling globally, with a strong focus on the US. It’s still day 1, come build the future of shopping with us! This position is remote-friendly. 📱 OUR PRODUCT TEAM Led by Fabien, our VP Product, Joko's Product team groups the passionate individuals behind our users' delight! From brainstorming to development to launch, the Product team's main mission is to turn ideas into reality by working hand-in-hand with the Engineering, Design and Business teams. ✨ WHY THIS ROLE IS SPECIAL Design at Joko has been a founding obsession. From day one, we've believed that a B2C product lives or dies on the quality of its experience, and we've held an unusually high bar on craft, motion, and detail across every surface of the app. Three things make this seat rare: * You inherit a real design culture, not a blank page. Joko already has a strong design DNA, a mature design system, and a product team where craft is non-negotiable across the board. You're not starting from zero, you're inheriting a high baseline and pushing it further. * You get to define what design at Joko becomes in the AI era. The way digital products are designed is changing fast. We are actively rethinking interaction models for our AI shopping assistant, and we want a design leader who has strong opinions on what world-class B2C design looks like when the interface itself is becoming conversational, generative, and adaptive. You will shape that, not just react to it. * You will live a genuinely unique scale moment. Going from a small design team to 7 Product Designers and a User Researcher, while expanding from France to Spain and the US, is a rare kind of stretch for a design leader. You get to do it here, with a product that already has the user base, the revenue, and the ambition to justify the investment. 🎯 WHAT YOU WILL DO As Head of Product Design, you will own the vision and execution of Product Design at Joko. Reporting to Fabien (VP Product), you will be hands-on early, then build and scale a high-performing Design and Research team as we grow. Your mission is to raise the bar on craft, coherence, and user-centricity across every Joko product. * Own the design vision and quality bar: You will define what great design means at Joko, the principles behind it, and the standards every shipped surface is held to. You will be the person the team looks to when there is a hard call to make on craft. * Stay hands-on where it matters: Especially early on, you will be deep in discovery, flows, UI, and interaction design on the highest-stakes problems. You know that a Head of Product Design who has lost touch with the work has lost the plot. * Shape the design vision for Joko AI: You will partner with Product Management and Engineering on what a shopping assistant powered by AI should feel like, including new interaction models that don't yet exist as best practices. You will have a strong point of view on this and the willingness to prototype your way to the answer. * Own and evolve the design system: You will treat the design system as a living product, not a documentation site. You will decide what scales, what gets refactored, and how it stays a force multiplier as the team grows. * Build a real research practice: Today, research is opportunistic. You will build a structured User Research function, hire our first User Researcher, and make sure insights actually shape the roadmap rather than sit in a Notion page. * Build and scale the team: You will grow Product Design to 7 Designers and 1 Researcher, recruit the people you want to bet on, coach them, and build a culture where craft and ownership are the defaults. * Partner closely with Brand Design: Joko's brand and product experience need to feel like one thing. You will work hand in hand with Brand to deliver a coherent 10/10 experience end to end, from the first ad a user sees to the cash back they receive in their account. * Make AI a real design advantage: You will deploy modern AI and design tools across the team's workflow to accelerate discovery, prototyping, and iteration. You have opinions on what works, what doesn't, and where human judgment still matters most. 👀 WHO WE'RE LOOKING FOR * Experience: You have 8+ years in Product Design with a strong hands-on background, and previous experience as a Lead or Head of Product Design (or equivalent senior design leadership role). You have built, scaled, and managed a design team before, and you know what good looks like at every stage. * B2C mobile-first DNA: You have shipped consumer mobile products that millions of people use. You instinctively understand the craft, the rhythm, and the stakes of designing for a B2C audience, and you don't need to be convinced that the details matter. * High-bar mindset: You hold the line on craft even when it's expensive. You'd rather ship one screen at a 10/10 than three at a 7/10, and you've built teams that share that instinct. Pixel-level rigor, motion that feels right, copy that earns its place on the screen, none of that is optional to you. * Strong sense of craft: You have a portfolio that shows end-to-end product thinking, sharp interaction design, and genuine attention to detail. You know the difference between a designer who follows patterns and one who shapes them. * Hands-on with AI and modern design tools: You have real, recent experience using AI to speed up discovery, prototyping, and delivery, with strong opinions formed from actual attempts (and actual failures). You are curious and experimental, not dogmatic. * Research instinct: You either have hands-on user research experience or have worked closely with researchers, and you know how to build a research practice that actually changes product decisions. * Design systems at scale: You have meaningful experience evolving a design system in a scaling context, and you have a clear point of view on what belongs in the system and what doesn't. * Cross-functional partnership: You have worked closely with Product Managers, Engineers, and Brand or Marketing Design teams, and you know how to make those collaborations produce a cohesive experience rather than a stitched-together one. * Coaching mindset: You genuinely enjoy growing designers. You know how to develop someone's taste, push their craft, and give the kind of feedback that actually moves the needle on a portfolio. * Languages: You are fluent in English, both written and spoken. French is a plus. * Mindset: You have an entrepreneurial mindset, you like challenges, you welcome feedback and you love constantly learning and getting better. 💎 OUR PERKS (Some of the benefits listed below are available to full-time positions only) At Joko, we believe that flexibility and trust are essential. Our work environment reflects this through: * Flexible remote : If you live in Paris, you can choose to work from our office or from home with no constraints. If you live elsewhere, we can provide access to a coworking space and a coworking budget. * Work from anywhere : Want to spend a month in Italy while working? You can work from most countries in the world for up to 3 months per year. On top of that, we offer plenty of perks: * 💸 Top-market compensation * 📈 Equity for everyone with the chance to own a piece of what you build * 🤖 Half-day each week dedicated to leveling up with AI by exploring new tools, iterating hard, and sharpening your skills * 🌴 Yearly offsite in amazing locations and budget for team-building events & monthly in-person gatherings * 💪 Contribution to your ClassPass subscription * 🍼 8-week leave paid 100% for the second parent * …and much more, check the full list here! 🤝 OUR HIRING PROCESS 1. Intro call: Quick screening with the Hiring Manager or the Talent team. 2. Step 1 – Team interview (45 min): Conversation with two Joko team members (could include the Hiring Manager, people from the team you’d join, or colleagues from other teams). 3. Step 2 – Role-specific assessments * For non-engineering roles: A take-home case study followed by a 45-min interview. We assess both your output and how you think in real time. The exercise will be relevant to your role (e.g. analysis, strategy, or process design). * For engineering roles: A 90-min live technical interview on CoderPad covering code understanding, review, system design, and product thinking (with AI serving as a collaboration tool). 4. Step 3 – Leadership interview (45 min): Conversation with a SteerCo member and a Founder. 5. References: Up to 3 calls with former colleagues or managers. ☕ You may also be invited for coffee with team members to get a feel for our culture.

You will report to our Head of Product Design and partner closely with Product Managers, Engineers, and Brand Design to deliver experiences that meet Joko's craft bar across every surface — mobile, web, and extension. * Design world-class product experiences across surfaces: You will own flows, interaction design, and UI on our highest-impact product problems, across the mobile app, the web app, the desktop extension, and the mobile Safari extension. You will think across surfaces, not just within one of them. * Take projects from discovery to delivery: You will be involved at every step — talking to users, framing problems with PM and Engineering, exploring directions, prototyping, shipping, and iterating after launch. You will treat user research as part of your craft, not something that happens elsewhere. * Shape the design vision for Joko AI: Joko is actively rethinking the shopping experience around AI, including new interaction models that don't yet have established best practices. You will bring strong opinions to how a conversational, generative, and adaptive interface should feel, and prototype your way to answers no one else has yet. * Push the design system forward: You will use, evolve, and challenge our existing design system as a living product. You'll know when to ship within the system, when to extend it, and when to advocate for refactoring it. * Partner closely with Brand Design: Joko's brand and product experience need to feel like one thing, from the first ad a user sees to the cash back they receive in their account. You will work hand in hand with Brand to deliver a coherent 10/10 experience end to end. * Use AI to elevate your craft: You will deploy modern AI and design tools into your day-to-day workflow to accelerate discovery, prototyping, and iteration.

You'd rather ship one screen at a 10/10 than three at a 7/10. * End-to-end designer: You are equally at home framing the problem with PM and Engineering, running quick user conversations, exploring directions, and polishing the final UI. You don't wait to be handed a brief. * Hands-on with AI and modern design tools: You have real, recent experience using AI in your design workflow, with opinions formed from actual attempts (and actual failures). You are curious and experimental, not dogmatic. * Design systems mindset: You have worked within a design system before and understand it as a force multiplier — you know when to follow it, when to extend it, and when to push back. * Cross-functional collaborator: You have worked closely with Product Managers, Engineers, and Brand or Marketing Designers. You communicate clearly, welcome feedback, and make the people around you better. * Ownership and drive: You are autonomous, accountable, and bring energy to the work.
