Job description
Senior Software Engineer
Company Overview
I'm working with a leading VC-backed AI start-up building production software for legal and professional services teams. The company is approaching ~£1m ARR, backed by top-tier international investors, and is now hiring a Senior Software Engineer to join a small, high-performing engineering team.
Job Summary
This is a hands-on Individual Contributor role for an experienced software engineer who enjoys building end-to-end systems, shipping quickly, and owning production software in an early-stage start-up environment. The team is small, highly capable, and operates with a strong bias toward ownership, speed, and real-world execution.
Key Responsibilities
- Owning features from design through to production and iteration
- Building backend systems in Python (FastAPI) and full-stack product surfaces in TypeScript/React
- Working on production AI systems including LLM agents, RAG workflows, retrieval, document intelligence, and tool calling
- Designing and operating asynchronous systems (queues, workers, event-driven workflows)
- Debugging production issues across backend systems, data pipelines, and user-facing product behaviour
- Building reliable, scalable systems with strong attention to failure handling, retries, and data consistency
Requirements / Qualifications
- 7+ years’ software engineering experience
- Strong backend engineering experience (Python preferred)
- Must have early-stage startup experience (non-negotiable)
- Proven ability to own features/systems end-to-end (design → build → deploy → operate)
- Strong engineering fundamentals and product mindset
- Comfortable working in ambiguity with evolving requirements
- Daily use of modern AI tools (Claude, Cursor, Codex, ChatGPT etc.) as part of your engineering workflow
- Evidence of using AI to meaningfully improve planning, implementation, debugging and delivery speed
- Strong bias toward execution, ownership and shipping value
- Desire to remain a hands-on IC (not moving into management)
