Responsibilities
• As a Senior Engineer at Flock you will own problems end to end, from design and build to deployment and measuring impact, working with engineers to keep our codebase clean and maintainable.Microservices & Event-Driven Backend Engineering • Microservices & Event-Driven Backend Engineering • Build and evolve services in a TypeScript monorepo organised around CQRS and Hexagonal architecture, with clear separation between domain, application, and infrastructure layers. • Design commands, events, and projections that let our services communicate asynchronously and stay decoupled as the product surface grows. • Work across a broad domain like pricing, underwriting, brokers, customers, vehicles, invoices, finance and more. • Product Config Front-End • Develop and extend our internal Product Config UI in React (TypeScript), the tool we use to define new products, configure rating and underwriting behaviour, and onboard new customers, businesses and sectors onto the platform. • Turn complex, schema-driven configuration into interfaces that underwriters and product managers can use confidently and safely. • Serverless & Cloud Infrastructure • Use your AWS experience (Lambda, API Gateway, S3, EventBridge, SQS, CloudWatch) to build and run the event-driven services that sit behind the product. • Care about observability, idempotency, and graceful failure in distributed, asynchronous systems. • Working hand-in-hand with your product manager, you’ll bring clarity to complex problems and help define sharply scoped, impactful deliverables. Your success won’t be measured by output alone, but by the lasting impact you make on our customers and on the team around you. • Curious how we build the future of fleet insurance?
