Role: Back End Developer – Java

Location: Porto, Hybrid

Required skills:

• At least 6 years of professional experience as an AI Engineer or in a similar role.
• Strong production software engineering: Python, testing, packaging, CI/CD, async, REST, Docker. You build products, not scripts.
• Real depth in LLM application engineering: prompt design, function calling, structured outputs, RAG, vector stores, with the Anthropic and OpenAI APIs.
• Evaluation-driven development as a core habit, not an afterthought. You treat evals as the source of truth.
• Experience building agentic systems end to end: systems that plan, write code, validate their own output, and improve over time.
• Familiar with the orchestration landscape (LangGraph, LlamaIndex, AutoGen, CrewAI) and opinionated about when a thin custom harness beats a framework.
• Working fluency with at least one cloud data platform and SQL: enough to build eval and verification infrastructure that your applied-data counterpart fills with domain rules. You do not need to be the deepest data expert in the room.

We offer:

• No-term full-time contract;
• Health Insurance;
• 22 days of paid vacation;
• 4 extra days annually (Carnival, Christmas Eve, New Year's Eve, Birthday);
