Python Developer (Azure / FastAPI) — £350/day — Outside IR35 — Hybrid, Central London (3 days on-site)
About the role
A significant opportunity to work with a leading global independent financial services firm, delivering a loan management platform that handles complex servicing workflows in a regulated environment. You'll be working to a high bar for correctness, traceability and testing — and you'll be based out of excellent offices in central London three days a week.
We are looking for a mid-level Python developer to join the delivery team. This is a hands-on engineering role in a small, senior team — you'll own features end to end and you'll have direct visibility of the client and the business problems you're solving.
What you'll be doing
- Building and maintaining Python services — FastAPI applications and Azure Functions
- Designing and consuming REST APIs, with an eye on validation, versioning and clear contracts
- Working with MS SQL Server: query tuning, stored procedures and migrations
- Working with Azure infrastructure — storage, queues, app configuration, monitoring
- Writing and maintaining automated tests
- Debugging and resolving defects in a live platform, including root cause analysis
Essential
- Solid commercial Python (typically 3+ years)
- Production experience with FastAPI, or a close equivalent such as Flask or Django REST
- Practical experience building serverless services on Azure Functions
- Strong MS SQL Server — you can write and optimise non-trivial queries, not just ORM calls
- Working knowledge of Azure cloud services and infrastructure
- Git, CI/CD pipelines, and a genuine testing habit
- Comfortable working directly with client stakeholders
Nice to have
- Financial services, lending or another regulated domain
- SQLAlchemy or Alembic
- Infrastructure as code (Bicep or Terraform)
- Azure DevOps
- Experience in a consultancy or client-facing delivery setting
Details
- Rate: £350 per day
- IR35 status: Outside IR35
- Contract length: 6 months minimum, with strong potential to extend
- Location: Hybrid — 3 days per week on-site, central London
- Start: [ASAP / September 2026]
