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);
Meal Allowance on card (Coverflex);
Referral Bonus;
Special discounts and flex options;
Training annual budget;
A great team-oriented culture;
Chance to become a part of a dynamically growing international company;
Challenging projects giving the unique opportunity to grow and learn.
