Full job description

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]

To apply

Send your CV through Indeed with a short note on a recent Python and Azure project you worked on and what your part in it was. No agencies.

Pay: From £350.00 per day

Work Location: Hybrid remote in London EC4M
