Senior Staff Engineer - Origination & New Products

We're hiring a Senior Staff Engineer to lead a new three-person

squad building product categories that don't exist at tem yet:

deep integration into Rosso, pricing capability, and deal-risk

tooling. This is a hands-on individual-contributor role, not

people management. You design, build, and review the hardest

parts of the system yourself, in Python, alongside the squad.

The stack is production-grade Python throughout: services built

on AWS Lambda and API Gateway, state and events handled with

DynamoDB and EventBridge, all wired together as event-driven

architecture. You will write Python daily, both for new product

integrations and for the pricing and risk logic that sits behind

them.

Compensation: GBP 117,850 (or local equivalent) plus equity.

Benefits include 25 days holiday plus your birthday off, a

remote/wellbeing budget, and fully remote working with no

internal meetings on Friday afternoons.
