Senior Software Engineer, Flock

• Expert proficiency in TypeScript, comfortable working in a large monorepo and across multiple services
• Expert-level experience in designing and operating event-driven backend systems on AWS (e.g. Lambda, EventBridge, SQS, API Gateway), including thinking through eventual consistency, retries, and idempotency
• Proven hands-on experience with CQRS, event sourcing, projections, and Hexagonal / Clean Architecture style codebases
• Exposure to a modern frontend framework like React
• Day-to-day experience with AI coding tools, and good judgement about when to lean on them and when not to

Desirable

• Join Flock as a Fullstack Engineer within our Expansion Team, where you'll play a pivotal role in building the platform that brings new fleets, new brokers, and entirely new sectors onto Flock. AI tools and coding agents are part of how we build here, and you'll use them daily
• You will drive consistency across our systems by diving deep into complex backend architectures and understanding core principles. As we expand into new sectors, your ability to master and enforce architectural patterns will directly shape the stability and scalability of how thousands of vehicles are quoted and brought on cover
• 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
• 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
• You'll own the delivery of features from ideation to deployment. Your work will have a direct and visible impact on how Flock wins new business, how brokers experience our platform, and how quickly we can open up entirely new lines of cover
• Build with AI as standard. Coding assistants and agents are part of the daily loop, and you'll help shape how the team applies them as we bring new sectors and products onto the platform
• 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
• 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
• 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
• 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
• Use AI coding tools and agents through the development lifecycle, from exploring designs to writing tests, while owning the quality of everything you ship
• 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
