Salary: £55,000 – £65,000 Location: London (hybrid, 2–3 days per week in office)
We are seeking a Backend Engineer to take ownership of our API and data infrastructure, building the core systems that power a large-scale, data-driven platform. This is a hands-on engineering role focused on designing robust data foundations, scalable pipelines, and high-performance APIs.
You will sit at the intersection of backend engineering and data architecture, shaping how data is ingested, structured, transformed, and served across the organisation, directly influencing platform reliability, data consistency, and system performance.
Key Responsibilities
- Design and implement database schemas supporting time-series, geospatial, multimedia, and relational data
- Build and maintain scalable data ingestion pipelines from multiple third-party APIs
- Develop high-performance APIs using Python and FastAPI
- Optimise database performance through indexing, query tuning, caching, and materialised views
- Design unified data models across heterogeneous data sources
- Manage database operations including migrations, monitoring, and optimisation
- Build resilient ETL pipelines with strong error handling and validation
- Support AWS-based infrastructure (RDS, S3, Redis, MongoDB, where applicable)
- Contribute to data architecture decisions across engineering and product teams
