GenAI Python Engineer
Location: Sheffield – Hybrid, 3 days per week onsite required
Contract: Inside IR35
Duration: 6 – 12 Months Rolling Contract
We are looking for an experienced GenAI Python Engineer with strong hands-on experience building end-to-end Generative AI and RAG applications within enterprise environments.
The successful candidate will be responsible for integrating data from multiple systems, extracting and parsing information from documents and images, working with structured databases, storing content within vector databases, building robust retrieval pipelines, and ensuring solution quality through evaluation frameworks and ground-truth validation.
Key Responsibilities
- Design and build enterprise GenAI and RAG-based applications using data from multiple systems.
- Integrate structured and unstructured data sources, including databases, APIs, files and document repositories.
- Develop pipelines for extracting and parsing data from documents and images using OCR and document intelligence tools.
- Process, structure, chunk and prepare extracted content for AI use cases.
- Store and manage parsed content, embeddings and metadata within vector databases.
- Build and optimise retrieval pipelines covering chunking, indexing, metadata tagging, filtering and reranking.
- Work with relational and enterprise databases for querying and data enrichment.
- Implement GenAI evaluation practices covering accuracy, groundedness, relevance, hallucination detection and response quality against ground truth.
- Build scalable APIs, services and production-grade AI workflows.
- Work closely with architects, platform teams and business stakeholders.
- Follow enterprise standards for security, governance, observability and performance.
