Lead / Senior Python Engineer

ABOUT THE ROLE

We're building a new insurance platform for a US specialty insurer, to replace the legacy system that runs their whole business today. It covers quoting, rating, policies, billing, claims, agency management and the vendor integrations around them. The first program goes live on the new platform in early 2027, and the existing book moves over a few months later.

You'll lead the backend. The design and data model are still open, so you'll shape them, then build most of it alongside a small team. The work is LLM-assisted and moves fast, and you'll demo it to the client every few weeks.

WHAT WILL YOU WORK ON?

• Design the core: a policy ledger with effective-dated changes, endorsements, cancellations and renewals, plus an audit trail that records every change

• Build a configurable rating engine. Underwriters change rates and rules through configuration instead of code changes

• Build background work with Celery: billing schedules, renewal batches, notices, and an event pipeline that stays reliable under load

• Connect the platform to around 20 outside vendors (payments, property data, e-signature, print and mail) behind one integration layer

• Migrate years of policy, billing and claims data out of the old system without losing a cent

• Set the standards, review the code, and keep the team unblocked

WHAT SKILLS AND EXPERIENCE ARE WE LOOKING FOR?

• 7+ years of backend engineering, most of it in Python

• Production FastAPI (or a similar framework), Celery or another task queue, and PostgreSQL you've tuned and modeled yourself

• You've designed a system from scratch and owned it in production

• AWS in production, with Docker, Terraform (or similar) and CI/CD you set up

• Experience with financial or transactional data: ledgers, money, dates that matter

• You use AI coding tools every day and know where they go wrong

• Clear spoken and written English. You'll talk to the client most weeks

• Insurance experience is a plus…
