Fabriq is looking for Senior Full-stack Engineers.

We have built a product that is a clear leader in its category. The next stage is not incremental improvement: it is, while delivering new features, raising the bar on robustness, performance, depth, and overall product quality.

You should expect complex technical and product challenges, and a strong level of responsibility. This is a role for engineers who want to have a real, lasting impact on both the product and the organization.

Working conditions

• You must be able to work fluently in French and in English.

• You must be comfortable working remotely, as most of the product department is remote. Remote work is possible but not mandatory.

• Permanent contract (CDI), forfait jours (218 days per year), with a 4-month renewable trial period.

• Office located at 18 Rue Yves Toudic, 75010 Paris. Hybrid setup with 2 days on-site every two weeks.

• For people living outside of Paris: travel costs covered up to 2 round-trips per month between home and office, plus accommodation covered for on-site days.

• 7 weeks of vacation per year.

• Vacation bonus paid in June.

• Health insurance coverage with Alan (covering partner and children).

• Swile meal vouchers (€10, €6 employer share).

• A company event every quarter.

• A company offsite every year.

Back-end

On the back end, the REST API is historically implemented with Django. However, new developments are done with Deno, so, TypeScript.

The database technology is AWS Aurora with Postgres compatibility, for both Django and Deno servers. With Deno, we use Drizzle as a lightweight ORM.

We heavily use Honeycomb and Sentry to understand what goes on at scale.

Our coding style in TypeScript is inspired by data-oriented programming.

Front-end

On the front end, our web app is a single-page application in Vue.js. It is partially in TypeScript; we migrate from JavaScript as we go.

The front-end application is continuously deployed with Cloudflare Pages, which allows for preview URLs on pull requests.

We use Claap to share videos of our work and Sentry to log errors.

We also have a mobile application, developed with Vue.js and Capacitor.

Infrastructure

The servers run as containers on AWS. We use ECS and Fargate, and we plan to use EKS in the future.

The infrastructure is entirely Terraformed, using CDKTF with TypeScript.

A small number of customers have dedicated infrastructures. We also support on-premise deployments using Kubernetes operators, alongside a deployment toolkit built with Nix.

For observability, we use Honeycomb, built on OpenTelemetry, giving us structured traces across the stack.

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.

Screening : 30 minutes, with Flavie, Talent Acquisition. Goal: assess the mutual fit between your aspirations and what Fabriq needs.

Technical interview : 90-120 minutes, with the Engineering Manager or a Senior Dev. Goal: deep-dive on your technical skills and ways of working.

Meet the team : 30 to 45 minutes, with members of your future squad (and the EM if not met before). Goal: get a feel for the day-to-day, ask anything you want about the team.

Reference check : 2 references required (former employer or close collaborator).

Founders interview : 2 x 30 minutes, with Octave and François, our co-founders. Goal: present the company’s vision and make sure Fabriq’s culture matches yours.
