Senior Full-Stack Engineer

Join Fabriq, a leading company in its category, as a Senior Full-Stack Engineer. In this role, you will face complex technical and product challenges while having a significant impact on both the product and the organization. You will work remotely, with the option to travel to the Paris office twice a month. The position offers a permanent contract, 7 weeks of vacation per year, health insurance coverage, meal vouchers, and various company events.

• Concevoir, construire et maintenir des systèmes complexes de bout en bout en tant qu'ingénieur logiciel full-stack senior.
• Utiliser des outils d'IA au quotidien et être enthousiaste à propos de leurs capacités en évolution rapide.
• Prendre en charge l'ensemble du processus, de la compréhension du contexte commercial à la livraison de solutions fiables en production.

**Technical excellence**

You have a strong software craftsmanship mindset: you care deeply about clean, readable, well-tested code, and you design systems that can evolve safely over time. You see code quality as a prerequisite for sustainable speed, not a trade-off.

To apply for this job, you must have

• Deep and proven experience as a full-stack software engineer, designing, building, and maintaining complex systems end-to-end.
• Strong mastery of software engineering fundamentals: architecture, data and domain modeling, performance, scalability, security, testing, reliability.
• The ability to surface trade-offs, decide, and act, even in ambiguous or high-pressure contexts.
• Strong convictions about how high-quality software should be built, defended with clarity and pragmatism.
• A rare balance between solid theory and hands-on pragmatism: you optimize for real-world outcomes.
• The ability to move fast without breaking things, knowing when to invest in quality and when to focus on business value.
• A genuine desire to write beautiful, maintainable code. Experience with software craftsmanship practices (TDD, DDD, Extreme Programming, etc.) is required.

**Ownership, impact, and product sense**

• You have a real affinity with Lean (not Lean Startup, just Lean).
• You favor small batches, incremental delivery, and continuous improvement. You are mindful of WIP and actively protect a healthy team flow.
• You take ownership end-to-end: from understanding the business context to shipping reliable solutions in production.
• You are comfortable questioning existing implementations, processes, and assumptions (including your own), and propose better alternatives.
• You don't just execute tasks: you shape solutions, improve systems, and raise the technical level of the product.
• You have the ambition and maturity to positively influence a team, a department, or the product as a whole.

**Soft skills & mindset**

• Above all, you care about improving the lives of end users.
• Highly curious, always learning.
• Autonomous, self-driven, comfortable operating with limited guidance.
• Fast learner, adaptable in unfamiliar domains.
• Open to feedback, able to question yourself, focused on continuous improvement.
• You enjoy collaborating and helping a team work better.
• You want to improve an organization, not just deliver code.

• **AI as a core skill**
• You see AI as a force multiplier for software craftsmanship: tighter feedback loops, faster learning, higher code quality and problem-solving.

We are looking for engineers who

• Use AI tools daily and are genuinely enthusiastic about their fast-evolving capabilities.
• Have firsthand experience of how AI dramatically improves productivity, code quality, and decision-making.
• Think critically about how AI can be embedded into workflows, products, and engineering practices, rather than used superficially.
• Want to stay at the forefront of how AI is transforming software engineering.
