CTO Founder Associate - internship

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 based in Paris. 🔥 THE CEO OFFICE The CEO Office is a hands-on team of high-potential generalists who lead Joko's strategic projects and, when needed, step in to reinforce teams on short to medium deployments. You'll take over a team of five Founder Associates, with room to grow as the company scales. As the leader of that team, your job is to build a team people are proud to be part of, where every Founder Associate grows quickly and contributes meaningfully to Joko’s most important priorities. 🎯 WHAT YOU WILL DO You'll be the CEO's strategic partner at a specific, rare moment in a company's life: a profitable scale-up entering its international chapter, expanding new business lines, doubling in headcount over the next 18 months, and investing heavily in AI — with a mature leadership team, a culture worth protecting, and a team that demands excellence. You'll report directly to Xavier (CEO), partner closely with co-founders Nicolas (CRO) and Alexandre (CTO), and serve as secretary of the Steering Committee, which is composed of the founders, the CMO, the COO, the VP People, and the Head of Online — putting you at the heart of every strategic decision the company makes. The Chief of Staff role is built around the CEO, and the CEO Office is in turn built around the Chief of Staff — together, the team exists to act as an extension of the CEO. The mandate is fourfold today, and you'll be the architect of all four pillars (as well as the future ones). 1. Governance. Your team and you will own the rhythm and quality of how Joko is run at the top — board meetings, executive team meetings, All Hands, and the communication cadence that ties them together. You'll play a central role as animator and alignment driver for the leadership team. 2. Proactive projects. Your team and you will lead the company-wide initiatives that matter most to the CEO and to Joko's next chapter — the kind of cross-functional, high-stakes work that doesn't naturally fit any single team. 3. Reactive missions. When a team needs short-term reinforcement, you'll deploy Founder Associates as a strike force, helping us address critical gaps without hiring in a rush. This will represent a decreasing share of the team's activity as the organization grows. 4. Culture. Like every member of the SteerCo — and like the CEO — you'll be expected to embody Joko's culture and lead by example. A word from Xavier "This is one of the most consequential hires I'll make this year. I'm looking for a real partner — someone with the rigor to challenge my thinking, the architectural mind to build durable systems, and the warmth to carry our culture as we scale. The Chief of Staff is, in many ways, an extension of me, and the right person will shape Joko's next chapter alongside Alex, Nico, and me." — Xavier Starkloff, CEO 👀 WHO WE'RE LOOKING FOR * 10+ years of experience, combining Tier 1 strategy consulting (BCG, McKinsey, Bain, or equivalent) with operating experience in a high-growth tech startup or scale-up. * Direct and substantive management experience, with a proven ability to hire and retain great talent. * Architectural thinking: You're as comfortable designing a multi-quarter operating model as you are fixing a broken process. You think in systems, not tasks. * Analytical rigor: Structured thinking, attention to detail, comfort with numbers, ability to write a board memo that holds up under CEO and investor scrutiny. * Emotional intelligence and stakeholder management: This role lives at the intersection of the CEO, the SteerCo, the Founder Associates, and every team in the company. You read people well, you build trust quickly across very different stakeholders, and you handle sensitive conversations with care. * Energy: You bring genuine drive and presence into a room. You'll be one of the cultural carriers of the company and a representative of the CEO. * AI fluency: You already use AI tools fluently in your own work, you have a point of view on how they reshape how teams operate, and you're excited to help Joko go further — the CEO Office is expected to lead by example on this front. * Efficiency: You're fluent in productivity tools, ruthless about prioritization, and known for delivering on time across complex projects with many stakeholders. You instinctively look for the highest-leverage version of any task. * Entrepreneurial mindset: You thrive in fast-moving, ambiguous environments. You take ownership without being asked, you welcome feedback, you're an insatiable learner, and you go the extra mile by default. * Languages: Fluency in English. * Location: Paris-based. Bonus: M&A, corporate development, and/or corporate finance exposure. 💎 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.

The Generalist named us among the Future 50. TL;DR We are seeking a talented Software Engineer to join our team. You will be responsible for framing and building high-value features and pieces of infrastructure in this role. As a Software Engineer, you’ll engage with technologies like Typescript, React.js, Node.js, Rust, shadcn, Kubernetes, Helm, Terraform, Elasticsearch, QDrant, PostgreSQL. Dust on Dust: as engineers, we have the incredible chance to work on a product we use every day. OUR CULTURE * Product-First: Unlike others focused on building foundation models, we're laser-focused on creating delightful product experiences with existing LLMs. * Small, High-Impact Team: Join a team of alumni from Stripe, Front, OpenAI, and other top tech companies. We're intentionally keeping our team small and mighty – every engineer has massive scope and impact. * Transparency & Collaboration: Our repository is open source, and we leverage serendipity between team members. We believe the best ideas emerge when the team shares information and insights openly. * Proactive Problem-Solving: If you see something broken, fix it—without waiting for permission.

Team members confidently advocate for their ideas while remaining receptive to new perspectives and evidence that might change their minds. If new data emerges, we adapt quickly. WHAT YOU’LL DO * Own critical features end-to-end: Design and implement core product experiences that directly impact how users interact with AI. * Scope and lead technical projects to completion with an eye on the full stack and a mind for opinionated prioritization. * Collaborate closely with users: Work directly with customers to understand their needs and rapidly iterate on solutions. * Build for scale: Design and implement systems that gracefully handle increasing complexity while maintaining simplicity for users. TECH STACK HIGHLIGHTS * Dust for Dust: We use Dust for Coding, debugging, knowledge search (runbooks, codebase), incident management, and task automation (i.e., creating issues). * Programming languages: TypeScript, Rust (not a requirement; we’re open to people who are experts in other programming languages). * Other relevant tools and technologies: * Front end: React, shadcn * Backend: NextJS, Kubernetes, Terraform/Helm * Database: PostgreSQL, QDrant, Elasticsearch * DevOps: Datadog monitoring, Github actions-based CI/CD BENEFITS & COMPENSATION * Competitive compensation: €30K - €150K* base salary * We offer substantial support for relocation, including a stipend up to €10k, finding an apartment in Paris, and supporting you with all residence and work permit-related procedures. * Significant equity package in a Sequoia-backed startup * Health insurance for you and your dependents * New MacBook Pro or Linux machine, monitor, keyboard, etc. * Beautiful office in the heart of Paris * Opportunity to travel to the US multiple times a year * Regular team events and offsites DUST ENGINEERING SALARY GRID Regarding compensation culture, we're going to lean towards Netflix's early philosophy: we are happy to review levels and compensation as early and as often as it makes sense to do so, not when the calendar says so. Regarding expectations associated with levels, we're including a very broad definition of each level below. When attributing a level at hiring, the expectation is for you to perform comfortably at this level within your first year. We'll set up catch-up times throughout that first year to keep track of your progress and communicate clearly whether you're matching these expectations. - Level I: Limited prior experience, learning the ropes - Level II: Level I + Autonomy - Level III: Level II + Rigorous dependability - Level IV: Level III + Excellence - Level V: Level IV + Leadership - Level VI: Level V + Impact on company trajectory *We can go higher for outstanding profiles. LOCATION We're prioritizing building our team with an in-person culture at our offices in Paris, San Francisco, and New York because we value the magic that happens when talented people work closely together. We have an office-first culture. Some of the best things about building at Dust are the energy, the fast decisions, and the unexpected conversations that unlock a hard problem, which happen because we are in the same room. Being together is not a formality, it is how we do our best work, and it is something we actively protect. That said, we hire people with strong judgement and we extend that trust to how they manage their time. When working from home makes more sense for what you need to get done that day, we trust you to make that call. WHY DUST The models are powerful enough. What's missing is the product layer where AI meets how companies actually work. That's what we're building: the infrastructure that lets any team turn scattered knowledge and tools into coordinated execution with agents they build, own, and run themselves. We use Dust ourselves every day. We get to shape how humans and agents collaborate while solving our own problems with the product we ship. That loop is rare, and it's why we move fast. If you're excited about defining a new category and want to join a determined team of optimists who focus on users, ship fast, and don't take themselves too seriously, we'd love to talk. Even if you don't check every box in our requirements, we encourage you to apply. We value diverse perspectives and backgrounds, and we're more interested in your potential and passion than a perfect match to our checklist. Learn how we think and work. * Our product constitution, a story about our mission * Agents at work - Latent Space, podcast with our cofounder, Stanislas Polu, 2024 * LLMs reasoning and agentic capabilities over time - dotAI, podcast with our cofounder, Stanislas Polu, 2024
