We are looking for a driven and enthusiastic Application Engineer (Full‑Stack Mobile) (m/w/d) to craft flawless mobile experiences while seamlessly tying them to robust backend architecture. If you are a versatile builder who obsesses over pixel‑perfect UX as much as efficient data fetching, you belong here.

• You have User Empathy: you don't just build to spec; you care deeply about the end‑user experience and the real‑world value your code delivers.
• You are a UX Champion: you have a deep passion for great UX design. You understand that a sluggish animation or a clunky user flow can ruin a great product, and you refuse to ship mediocre interfaces.
• You are a Problem Solver: you have a deep engineering mindset, remain open‑minded to new paradigms, and love untangling complex state‑management or cross‑platform quirks.
• You are a Seamless Full‑Stacker: you don't believe in strict frontend/backend boundaries.
• You can effortlessly jump from tweaking mobile UI components to optimizing a backend resolver without breaking a sweat.
• English proficiency (written and spoken, minimum B2 level).

• Experience with experimentation frameworks (A/B testing) and impact measurement
• Mobile/Frontend:
  React Native (deep exposure to both iOS and Android ecosystems)
• Data Layer: REST & GraphQL (building, querying, and optimizing)
• Backend: comfortable diving into server‑side logic to support your frontend needs
• Workflow: modern tools and CI/CD pipelines to ship fast and break fewer things.

• Contract type:
  Permanent
• Working hours:
  
  Full‑time – 40h/week, from Monday to Friday
• Hybrid Barcelona:
  We love remote work but also value in‑person collaboration. You can work from home most of the time, but we expect you to swing by our Barcelona office a couple of times a week to brainstorm, whiteboard UX flows, and grab a coffee with the team.
• Salary:
  Attractive compensation including equity in the company
• Equity in the company (stock options plan)
• A seat on a scale‑up with skyrocketing growth
• Development of your entrepreneurial spirit having the chance to implement real‑impact business decisions
• Multicultural and international team
• Collaborative and smart environment to work and learn
• Free coffee to kick‑start your day and free beers to celebrate together
