⭐ Mission

Join us as a Freelance Full-Stack Engineer to build one of Qonto's first internal applications: a modern, high-quality People platform that transforms the daily experience of 1,700+ Qontoers - from compensation cycles and performance reviews to everyday HR workflows.

You'll work hand-in-hand with Mélodie, our Head of People Systems, on a high-ownership mission: co-define the product vision, design the architecture, and ship to production. This is not a staff-augmentation engagement - it's a mandate for someone who builds like an owner.

👩‍💻🧑‍💻 As our Freelance Full-Stack Engineer, you will

• Ship the People platform MVP by November 2026: migrate key Workday modules into a custom internal app (React front, Python/Go back) that handles comp cycles, performance reviews, and daily HR workflows for 1,700+ Qontoers - on time and with zero compromise on quality.

• Co-define the product vision and roadmap with Mélodie: run user discovery with People teams, challenge specs, and help decide what gets built first - not just how to build it.

• Design for security and compliance from day one: architect systems that handle sensitive People data (GDPR, access controls, data residency) with the rigor the context demands.

• Ship faster with AI: leverage AI tools (Cursor, Claude Code, Copilot…) in your daily workflow and build AI-enabled features where they create real leverage for the People team.

• Enable long-term adoption: document your work, run training sessions, and set up governance so the People team can own and evolve the tools long after the mission ends.

🏅 What we're looking for

• Strong full-stack engineering (backend primary): You've shipped production apps end-to-end, handling sensitive data. React and Python/Go are familiar - but we're evaluating craft and delivery capacity, not your exact stack.

• AI-native workflow: You use AI tools daily to ship faster - code generation, testing, architecture support. Not experimenting - actually delivering.

• Architecture & security instincts: You design for GDPR, access control, and data residency from the start. Security is not an afterthought.

• Product engineer mindset: You've shaped what to build, not just how. You run user discovery, challenge specs, and iterate on real feedback.

• High autonomy + owner mindset: You've delivered complex, ambiguous projects with minimal guidance. You set your own priorities, communicate proactively, and unblock yourself.

• Bonus: Experience with HRIS/People tools (Workday, ATS, Payroll systems) or internal tooling for large organisations.

🔧 What you'll get

• A greenfield mandate with direct access to decision-makers - no layers of approval, no waiting on committees

• A stack built on React and Python, likely evolving toward Go / Workday REST middleware - adaptability valued over stack matching

• Unlimited access to AI tools: Cursor, Claude Code, Copilot, Notion AI, Dust

• A culture where autonomy is the default: you own the architecture, set the direction, and ship

• A mission with direct impact on every Qontoer's daily life from day one

🤝 Your main point of contact

You'll report to  Mélodie, Head of People Systems.

• Her path: With 10+ years in HR and HRIS - from Coca-Cola Enterprises to ConvictionsRH, then Head of HR Digital CoE at Pernod Ricard and Head of People Systems & Performance at Doctolib - Mélodie has led large-scale HR transformation programs using data and automation. She joined Qonto in April 2025 and brings deep functional HR expertise with a product-minded, operational-excellence lens.

• What she can bring to the team: As a manager, she strongly believes in empowering her team. You can expect real ownership and freedom over your work. She will provide you with the trust and autonomy needed to innovate, while strategically guiding the team through challenging organizational transformations.

💬 Hiring Process

• 2 Interviews (1 hour each): first with Samy (your Recruiter), and then with Mélodie

• A skills test (done asynchronously) to demonstrate how you think and give you a taste of what working at Qonto could be like

We aim to have the hiring process last 10 days max, from first interview to potential offer🤞

If you've read this far and thought "that sounds like me but I don't check every box" — apply anyway. We hire on potential and mindset, not checklists.
