AI Engineer - HealthTech Start-Up - Java/Kotlin, Python, LLMs, MCP

I'm working with a fast-scaling HealthTech 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 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
