I'm working with a fast-scaling Health Tech company building an AI-powered operating system for the healthcare workforce.
This isn't a traditional backend role, they're looking for a builder mindset — someone who blends backend engineering with data/AI thinking and is comfortable using LLMs as a core part of how they ship products.
What makes this interesting: AI-augmented development is the default (not a nice-to-have)
Real-world impact: solving workforce challenges in healthcare
Full ownership — from idea → production
Stack includes Java/Kotlin + Python,



LLMs and MCP but tech-agnostic mindset is key You might be a fit if: You've adopted tools like Cursor / Claude Code early
You care more about shipping than perfect code purity
You enjoy working at the intersection of product, data, and engineering
You thrive in fast-moving, high-ownership xghoner environments Not for you if: You want a traditional 9–5 or purely backend role
You prefer structured, process-heavy environments
You're focused on research over real-world application Barcelona-based, strong office-based presence and start-up culture Fluent Spanish required
Pays up to €80k + equity
