Job description

Location:

Remote (UK) | Monthly team meet-ups | Optional London co-working space

We're partnering with an innovative, well-established insurance technology company that's transforming the auto insurance industry. By combining telematics, real-world driving behaviour and proprietary machine learning models, they've built a smarter underwriting platform that delivers lower costs, greater accuracy and industry-leading loss ratios.

As the business continues to grow, they're looking for a talented Backend Engineer to help build the next generation of their platform.

The Opportunity

This is an opportunity to work on modern, cloud-native systems—not legacy applications.

You’ll play a key role in designing, building and maintaining the scalable APIs, backend services and distributed systems that power the company's core insurance platform, mobile applications and machine learning pipelines.

You’ll join a collaborative engineering team that values clean code, thoughtful architecture and solving meaningful customer problems, while having genuine influence over the technical direction of the platform.

What You’ll Be Doing

• Design, build and maintain scalable backend services using Node.js and TypeScript
• Develop APIs and services supporting the insurance platform, mobile applications and third-party integrations
• Contribute to system architecture and help shape the long-term engineering strategy
• Work closely with Product, Design and Engineering teams to deliver high-quality features
• Take ownership of the services you build, ensuring reliability, scalability and observability
• Participate in on-call support and continuously improve system performance

You’ll be working with a modern technology stack including:

• Node.js & TypeScript
• PostgreSQL, Datastore & Redis
• GraphQL
• React & React Native
• Event-driven architecture using Pub/Sub
• Domain-Driven Design (DDD)
• Hexagonal Architecture
• Terraform
• CircleCI

About You

We're looking for an engineer who enjoys building reliable, scalable backend systems and takes pride in writing clean, maintainable code.

You’ll ideally have:

• Commercial experience developing backend applications with Node.js
• A solid understanding of software architecture and distributed systems
• Experience designing and building production-grade APIs
• Strong problem-solving skills and excellent computer science fundamentals
• The ability to communicate technical concepts clearly with both technical and non-technical stakeholders
• Experience working within Agile environments

Nice to Have

Experience with any of the following would be advantageous, but is by no means essential:

• GraphQL
• Event-driven architectures
• Terraform
• DataDog
• Domain-Driven Design (DDD)
• Hexagonal Architecture
• Start-up or scale-up engineering environments

What’s on Offer?

• Salary of £50,000–£80,000 DOE
• Fully remote within the UK
• Monthly in-person engineering meet-ups
• Optional London co-working space if you enjoy office collaboration
• Modern tech stack with greenfield development
• High levels of ownership and technical autonomy
• The opportunity to help shape a rapidly growing engineering platform

If you're passionate about backend engineering and want to build scalable software that makes a real impact, we'd love to hear from you.
