About the role
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. We've now raised over £50M and our goal is to become the leading insurance company for connected and autonomous vehicles, and we're building a world-class team to help us get there. We're an AI-first business, so whatever
the role, we want people who reach for AI by default, stay curious about what it can do, and use it to work faster and think bigger.
THE ROLE Join Flock as a Senior Software Engineer on our Retain team , where you'll play a pivotal role in building and developing the services that help our fleet customers see the value of Flock, embed us into their daily workflow, and operate safer, more profitable fleets. You'll use AI tools and coding agents as a normal part of how
the team designs, builds and operates. WHAT WE THINK IS MOST EXCITING
