This role combines engineering rigor with business impact, delivering scalable retrieval, grounding, and evaluation capabilities. A meaningful chance to shape how AI touches real work for leading enterprises.
Retribuzione / Benefits competitive salaries 55.000 - 65.000 Eur broad range of benefits diversity and cultural differences are cherished
Responsabilità Decompose business processes into steps, tools, handoffs, and decision points for agent-based execution
Design and implement retrieval pipelines with chunking, embedding models, hybrid search, and grounding to source data
Treat prompt and context engineering as an engineering discipline with versioning, tests, and measurement
Build the evaluation layer with datasets, automated scoring, and regression suites
Instrument production systems for observability: traces, latency, costs, failure rates, and drift
Own end-to-end quality and diagnose failures to their root cause across retrieval, reasoning, tooling, or data
Balance model quality, cost, and latency, adapting choices as models evolve
Collaborate with business experts to extract domain logic and translate it into testable artifacts
Take agents into production with platform and infrastructure teams and monitor live behavior
