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