Senior Software Engineer | London | £100,000 – £160,000 | Python | FastAPI | AWS
Location: London based – hybrid
Salary: £100,000 – £160,000 + equity
Tech Stack:
- Backend: Python (experience with FastAPI or Django or Flask beneficial)

- AWS – experience with Azure & GCP beneficial
Are you a backend engineer who cares more about building robust systems and being part of a well-funded, fast moving start-up?
We are working with a recently funded Series A technology company building AI powered automation for real world, critical workflows. Their platform captures operational knowledge and turns it into production grade systems that AI can interact with safely and reliably.
This is not applied machine learning, not foundation model development, and not experimental agent playgrounds.
The work is focused on the engineering around AI: evaluation, control, reliability, and building systems that behave predictably in production. Engineers work closely with users, own problems end to end, and shape both the technical and product direction in a small, high trust team. It is an intellectually demanding environment where quality, correctness, and long term system design genuinely matter.
Responsibilities
- Design and build backend systems that power a complex, evolving platform using Python
- Own data models, schemas and database design with a strong focus on correctness and scale
- Build ingestion pipelines and integrations with production customer systems
- Develop tooling that enables AI capabilities while maintaining strong control and evaluation standards
- Work directly with customers to understand workflows and translate them into reliable systems
- Contribute to architectural decisions and long term platform evolution
Requirements for Success
- Strong experience as a backend or systems focused engineer
- Deep Python experience with excellent engineering fundamentals, or equivalent depth in a strongly typed language
- Strong SQL skills and experience designing schemas
- Experience building complex backend systems that evolve over time
- Comfort working in ambiguous, early stage product environments
- Experience with data ingestion pipelines or internal tooling for AI or data teams
The engineering team is currently small and senior, with a strong academic and systems background. There is no formal product team. Engineers own user experience, technical decisions and delivery. The culture values thinking time, technical rigour and clear communication over speed for its own sake.
Benefits
- Competitive salary
- High trust & autonomy working environment
- Meaningful equity
- High ownership role with direct influence on product and technical direction
This role will suit someone who enjoys hard systems, deep thinking, and building things that actually hold up in the real world.
