Senior Full Stack Developer

About Fabriq

Fabriq is the SaaS platform that's bringing factories into the 21st century. We replace the whiteboards and Excel spreadsheets still used in 80% of industrial sites, equipping operators, team leads and managers with a tool to track real-time KPIs (safety, quality, lead times, productivity), surface and solve shop-floor problems, run their daily routines, and collaborate across teams.

We're already deployed on 600+ industrial sites across 40+ countries, with reference customers like Safran, Airbus, Renault, Scania, LVMH, Andros, Bel, Merck and Lonza.

We hit profitability in late 2024 and raised €22M in June 2025 with Expedition Capital to accelerate internationally (US, UK, DACH). The team is ~110 people today.

Our long-term ambition: become the Operating System of every production floor, with an ambitious AI roadmap to empower frontline teams even further.

The role

We've built a product that's a clear leader in its category. The next stage isn't incremental: while shipping new features, we're raising the bar on robustness, performance, depth, and overall product quality.

That means complex technical and product challenges, and a high level of responsibility. This role is for engineers who want to have a real, lasting impact on both the product and the organization.

Our stack

Back-end

• REST API historically built with Django. New developments are written in TypeScript with Deno.

• AWS Aurora (Postgres-compatible) for both Django and Deno servers.

• Drizzle as a lightweight ORM on the Deno side.

• Honeycomb and Sentry to understand what happens at scale.

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

Front-end

• Single-page app in Vue.js, partially TypeScript (we migrate from JavaScript as we go).

• Continuously deployed via Cloudflare Pages with preview URLs on every PR.

• Mobile app built with Vue.js + Capacitor.

• Claap for video sharing, Sentry for error tracking.

Infrastructure

• Containers on AWS (ECS + Fargate today, EKS on the roadmap).

• Fully Terraformed with CDKTF in TypeScript.

• A small number of customers run on dedicated infrastructures, and we're building a proper on-premise deployment solution.

What we're looking for

Technical excellence

You have a strong software craftsmanship mindset: you care 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.

You bring:

• Deep, proven experience as a full-stack engineer, designing and shipping complex systems end-to-end.

• Strong 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.

• Hands-on experience with software craftsmanship practices (TDD, DDD, Extreme Programming, etc.), required.

• A genuine taste for writing beautiful, maintainable, long-lasting code.

Ownership, impact & product sense

• Affinity with Lean (not Lean Startup, actual Lean).

• You favor small batches, incremental delivery, continuous improvement. You're mindful of WIP and protect a healthy team flow.

• You take ownership end-to-end: from understanding the business context to shipping reliable production software.

• You question existing implementations, processes and assumptions (including your own), and propose better alternatives.

• You don't just execute, you shape solutions, improve systems, and raise the technical level around you.

• You aspire to influence a team, a department, even a product, through both your contributions and your example.

AI as a core skill

We see AI as a force multiplier for software craftsmanship: tighter feedback loops, faster learning, higher code quality.

We're looking for engineers who:

• Already use AI tools daily and are genuinely enthusiastic about them.

• Have firsthand experience of how AI improves productivity, code quality and decision-making.

• Think critically about how AI can be embedded into workflows and products, not used superficially.

• Want to stay at the cutting edge of how AI is reshaping software engineering.

Profiles that aren't aligned with this vision won't be a fit for the role.

Soft skills & mindset

• Above all, you care about improving the lives of end users.

• Highly curious, always learning.

• Autonomous, self-driven, comfortable with limited guidance.

• Fast learner, adaptable, at ease in unfamiliar domains.

• Open to feedback, able to question yourself, focused on continuous improvement.

• You enjoy collaborating and helping a team get better.

• You want to improve an organization, not just ship code.
