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 (France and Spain). 📱OUR ENGINEERING TEAM Our Engineering team excels at solving cutting-edge technical challenges with elegant solutions. With a strong focus on product innovation and design, they are shaping the future of the shopping experience. Their ambition is to have a positive impact on the everyday lives of hundreds of millions of users around the world. Software Engineers in the Engineering team work hand-in-hand with the Product team, from exploration, design, and roadmap prioritization to implementation, and deployment in production. At Joko, we have firsthand experience that teams with engineers who possess a diverse range of skills, and where engineering and product collaborate closely, are able to deliver a truly delightful and innovative user experience. The Engineering team is currently growing fast to continuously innovate on all parts of our product and tech stack and to empower the revolution of the way people shop online. 🎯 WHAT YOU WILL DO At Joko, we’re entering a new stage of scale: over half a million active daily users, and zero-downtime expectations. As our Platform Engineer, you’ll shape and lead our platform efforts. You’ll be the first senior engineer focused on these topics, building on work currently spread across the team and turning it into a clear, reliable, high-leverage platform that helps everyone ship faster and safer. * Infrastructure & reliability: Own our production infrastructure end-to-end: resilience, capacity, and cost. You'll make our systems more robust as we grow, simplify where it makes sense, and turn infrastructure efficiency into a real business lever — not just an engineering concern. * Observability & incident response: Build the visibility layer that lets us catch problems before users do. You'll centralize logs and alerts across our tools, define what "healthy" looks like, and design an on-call experience that's sustainable — clear signals, fast response, no noise. * Security & access control: Raise the security bar in a way that scales with the team. From access management and secrets handling to compliance work and release hardening — you'll make security a natural part of how we ship, not a checkpoint at the end. * Developer experience & release quality: Treat engineering workflows as a product. You'll improve how we build, test, and release — making the right way the easy way, and giving teams the confidence that what they ship is solid before it reaches users. * AI-powered internal tooling: Help shape how we use AI internally: automation, agents, and tooling that multiply the execution capacity of every team. You'll contribute to a real shift in how we work — not by replacing engineers, but by removing the friction that slows them down. * Technical leadership: Define the platform roadmap, align stakeholders, and lead cross-team initiatives end-to-end. Bring structure and mentorship so platform practices become shared — not heroic individual efforts. 👀 WHO WE'RE LOOKING FOR * Experience: 5+ years of software engineering experience, with significant time spent on platform, infrastructure, or reliability at scale. You've operated at a senior or staff level and you're ready to be the first dedicated owner of these topics. * Production reliability & scale: Strong track record operating and evolving production systems (observability, incident response, scalability, reliability patterns) in environments with real traffic and high expectations. * DevOps & automation mindset: You consistently improve how engineers ship—CI/CD, releases, automation, tooling—and you care about fast feedback loops and day-to-day developer productivity. * Strong software engineering foundations: You are a strong engineer first — you write clean, testable, maintainable code and bring that rigor to platform work. You're comfortable rolling up your sleeves and contributing directly to the codebase when needed, and you see that as a natural part of the job. * Cost/performance tradeoffs: You're comfortable making pragmatic architectural decisions that balance reliability, latency, and cloud costs, with a clear focus on impact. * Security fundamentals: You have solid infrastructure security basics (permissions/IAM, secrets, least privilege, hardening). You don't need to be a full-time security specialist, but you know how to raise the baseline. * Cloud & modern infrastructure: Experience with AWS (we run a server-less setup) or equivalent; familiarity with IaC and modern deployment patterns is a strong plus. * Product-minded: Strong sensitivity to user experience, performance metrics, and real-world usage at scale. * Problem solver: Comfortable working in complex, evolving codebases, with the patience and pragmatism to improve them incrementally. * Collaboration & influence: You communicate clearly, raise the bar through reviews and mentorship, and partner well with engineers and product stakeholders. * Languages: Fluent in English, both written and spoken. French is not required. 💎 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.
