Lead a small team covering frontend, backend and QA, including sprint execution, technical direction, code reviews and mentorship.
Own the agentic orchestration layer in Python (LangChain or similar): routing, tool-calling, state/memory, guardrails and prompt/configuration management.
Build and maintain backend services/APIs that connect UI → orchestration layer → graph database (queried via SPARQL) → retrieval (Graph RAG) → LLM.
Implement Graph RAG patterns: entity linking, context assembly, grounding/citations and response formatting for consumption in the UI.
Deliver reporting features in the UI based on the agentic framework, such as: conversation summaries, task results and traceability to evidence in the graph, latency, token/cost signals, retrieval hits and error rates.
Partner with ontology/graph engineers to ensure correct query patterns, performance tuning and schema alignment.
Establish engineering standards: structured logging, telemetry, exception handling, secure secrets management and performance optimization.
Ensure MVP quality: testing strategy, automated tests where feasible (unit/integration) and release readiness.
Responsible for containerized deployment: packaging services in Docker, supporting CI/CD, promoting between environments and implementing rollback practices in Azure.

6+ years of software engineering experience, with at least 2+ years in a technical lead role.
Strong experience in Python developing production services/APIs (preferably FastAPI/Flask).
Hands-on experience with LLM/agent frameworks (preferably LangChain) and tool orchestration patterns.
Experience integrating with RDF/knowledge graphs and executing SPARQL (directly or via graph services).
Experience delivering modern web applications (preferably React) and leading frontend-backend collaboration.
Practical experience with Docker packaging and container-based deployment workflows.
Experience working in agile teams (Scrum/Kanban), collaborating with product and architecture and delivering iteratively.

At Capco we promote an inclusive culture. We value diversity in all its forms.
We offer various inclusion and social-responsibility initiatives through internal committees run by our employee community.
