About Us

We are a semantic intelligence platform that transforms unstructured organisational data into queryable knowledge graphs powered by agentic AI. We serve enterprise clients across pharma, finance, and regulated industries — helping them unlock institutional knowledge through Graph RAG and multi-agent AI systems. Fast-moving team, technically ambitious problems, high engineering standards.

The Role

You’ll be a key contributor to our backend — working across ETL pipelines, FastAPI services, and the agentic AI workflows that power our intelligence layer. You’ll collaborate closely with the CTO and a small senior team, contribute to architecture discussions, and bring your own thinking to the problems we’re solving. This is a role for someone who takes pride in the quality of their work and wants to be part of building something meaningful.

What You’ll Work On

• Build and maintain FastAPI services powering our multi-tenant backend
• Develop Python ETL pipelines that ingest and transform unstructured data into knowledge graphs
• Write well-tested, production-grade code with Pytest across unit, integration, and pipeline levels
• Use Pydantic for schema design, validation, and structured LLM output handling
• Contribute to the agentic AI layer — tool definitions, orchestration logic, LLM integration
• Collaborate on Neo4j data modeling and participate in architecture discussions

What We’re Looking For

• 5+ years Python in production environments
• Strong FastAPI and async Python experience
• Solid Pydantic v2 proficiency
• Test-driven mindset with comprehensive Pytest coverage
• Experience building ETL or data processing pipelines
• Familiarity with LLM APIs (OpenAI, Anthropic, or similar)
• Collaborative, communicative, and comfortable in a fast-moving startup environment

Nice to have:

• Neo4j / Cypher
• LangGraph
• RAG / vector databases
• Regulated industry background
• Multi-tenant SaaS
