Role description
AI Engineer (Contract) β Semantic Search Project
Location: Remote (must be based in UK)
Contract: ~3 months, starting September (handover available before end of month)
Weβre working with a Private Equityβbacked Data business that has evolved a mature legacy environment into a complex data platform delivering structured intelligence, natural language query, and semantic search capabilities.
The business is now in Phase 3 of a hybrid/semantic search build and needs an AI Engineer on a contract basis to step in immediately and deliver. This is a hands-on execution role, not R&D, not discovery.
What Youβll Do
β’ Deploy embedding models on SageMaker.
β’ Build pipelines with Step Functions, Lambda, S3, EventBridge.
β’ Generate embeddings and push them into OpenSearch.
β’ Implement hybrid queries (semantic + lexical).
β’ Update search endpoints.
What Youβll Need
β’ Proven experience productionising semantic/hybrid search pipelines.
β’ Deep knowledge of AWS OpenSearch, SageMaker, embeddings, vector DBs.
β’ Expertise with Step Functions + Lambda.
β’ Ability to hit the ground running and deliver against a defined design.
Why This Role?
β’ Immediate impact on a mission-critical AI platform.
β’ Focused on delivery, not experimentation.
β’ Work with a sharp, low-attrition engineering team.
