Descripción

We’re looking for a Full Stack Engineer who enjoys building 0→1 products and wants to help shape AI tooling for the mobility industry.

  1. Strong full-stack ability (stack doesn’t matter)
  2. Comfortable with ambiguity and messy data
  3. Able to take problems from idea → shipped solution
  4. Product mindset: focused on outcomes, not just code
  5. Strong opinions, loosely held

We care about how you think and what you’ve built.

You’ll work across the full stack on problems where data is incomplete, inconsistent, and sometimes wrong.

Typical work includes:

  1. Designing and evolving the canonical data model
  2. Building pipelines that handle messy, real-world inputs
  3. Defining how the system resolves conflicting data
  4. Building and orchestrating agents that reason over the data and take action
  5. Designing how those agents behave, fail, and recover
  6. Making outputs explainable and auditable (not just “LLM says so”)
  7. Shipping features end-to-end, from idea to production

This is as much a product role as it is engineering. You won’t just implement decisions, you’ll shape how the system behaves.

Tech stack

We use simple, reliable tooling and choose the right tool for the right moment.

  1. Ruby on Rails (API)
  2. PostgreSQL
  3. React / Next.js
  4. Python (data + AI orchestration)
  5. AWS / Render

What we offer

  1. Competitive salary of €40,000 to €80,000
  2. Meaningful equity
  3. Flexible working (3 days in office)
  4. Apple hardware
  5. Barcelona HQ in front of the beach (Norrsken House)
  6. Generous holiday + public holidays
  7. Team off-site in fun places! (We've been to Girona, Lisbon and Wales so far)

Proceso de contratación

We keep our hiring process simple and focused on real work.

  1. 30 min – Informal intro chat
  2. 75 min – Technical pairing session using a real-world problem (no homework)
  3. 45 min – Cultural conversation with the CEO
