Full Job Description
A BIT ABOUT FLOCK At Flock we do insurance very differently. We're nearing 1 billion connected, insured miles. Meaning our real-time, data-driven approach enables us to price connected vehicle insurance and assess risk better than ever before, giving fleet owners the insights they need to improve safety. We don’t just pay claims; we help our customers prevent them. We now insure hundreds of fleets in the UK, including the likes of Amazon, DPD, Uber and Bolt.

Work at the Intersection of Data and UX Partner closely with underwriters, pricing engineers and product managers to transform complex submission data and rating logic into intuitive, performant interfaces. You'll be a key bridge between Flock's underwriting engine and the broker and fleet customers who rely on it every day. Modern AWS-Driven Stack Leverage AWS services like Lambda, API Gateway, and EventBridge to build scalable, event-driven systems that power our quote-to-bind pipeline. While this is a full-stack role, you'll have ample opportunity to expand and apply your AWS knowledge in a production environment. Ownership and Autonomy You'll own the delivery of features from ideation to deployment. Your work will have a
