At Mindera, we believe in building software that improves lives. As a Senior AI Engineer for AI Systems you own the machinery that makes our accelerators reliable and reusable: the agent harness, orchestration, the platform-agnostic core, the evaluation infrastructure, and the observability that tells us whether a change made things better or worse. You are the reason delivery teams can trust output from a non-deterministic system.What you'll own:The reusable accelerator core and the multi-agent workflows built on it.Agent design across coding, planning, review, and testing agents, with tool-calling and human-in-the-loop where it earns its place.The evaluation pipelines and telemetry that make quality measurable and regressions visible.Reliability, cost control, and observability for agentic systems in real use.RequirementsKey Qualifications:At least 6 years of professional experience relevant for the role (probably a mix of AI Engineering and Software Deveopment).Can deploy a working customer facing app themselves including devops, front end, backend etc Has experience building a production app which was modern, could handle scale, fast, responsive etc AI SDLC in production experienceReal 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.BenefitsThe Things We Really Care About: Health Insurance, because health comes first Flexible working hours Open holidays, take the time you need for yourself Profit distribution for everyone Mindera Annual Trip, Sports, and sharing groups to connect and have fun! Training & conferences, create your own training plan Child Care vouchers Other Good Things: Choose Laptop & Peripherals that best suit your needs Hotspot with unlimited usage (PT), for work or Netflix ;) We have amazing offices in Porto, Aveiro, and Coimbra if you want to physically connect with minders. Remote from Portugal is also an option. Remote from other Countries will depend on your current location and Projects.
