Rethink how modern insurance platforms perform by engineering intelligent, distributed backend systems that replace legacy constraints with high-precision, real-time data.
RMG is partnering with an innovative insurtech specialist that uses telematics and proprietary machine learning models to revolutionise underwriting accuracy. We are seeking a full-time, permanent Backend Engineer based anywhere in the UK to help build and refine the next evolution of their core technology platform. Working within a fully remote environment, you will take ownership of modern, cloud-native services that power core insurance processing, dynamic mobile apps, and high-volume data pipelines.
Key Responsibilities
Design, develop, and maintain resilient, scalable backend services and APIs using Node.js and TypeScript.
Architect and implement production-grade integrations, distributed messaging flows, and data services powering core underwriting systems and user-facing mobile applications.
Champion clean system architecture, collaborating directly with Product, Design, and Engineering teams to translate complex business needs into elegant technical solutions.
Maintain complete end-to-end ownership of your services, ensuring high reliability, system observability, performance, and operational excellence.
Participate actively in agile ceremonies and collaborative system design sessions to influence long-term technical direction.
Required Skills & Experience
Substantial commercial backend engineering experience using Node.js and modern JavaScript / TypeScript.
Proven track record designing, building, and maintaining production-grade APIs, microservices, and distributed systems.
Strong grasp of software architecture fundamentals, clean code principles, and scalable system design.
Demonstrated experience delivering software collaboratively within Agile teams (Scrum or Kanban), communicating complex technical concepts effectively across disciplines.
Deep problem-solving capabilities with a focus on writing maintainable, well-structured, and highly reliable code.
Nice-to-have
Hands-on experience with Google Cloud Platform (GCP), including Cloud Run, GKE, Datastore, or Cloud Pub/Sub.
Practical exposure to event-driven architectures, message queues, and asynchronous workflows.
Familiarity with GraphQL, Domain-Driven Design (DDD), or Hexagonal Architecture.
Experience utilizing Terraform for Infrastructure as Code and DataDog for distributed tracing and observability.
Prior background navigating the fast-paced, high-ownership environment of a technology start-up or scale-up.
What We Offer / Why Join
This role gives you the opportunity to work entirely on modern, cloud-native services with high technical autonomy, completely free from legacy systems. You will enjoy a fully remote UK setup with the choice to access a London co-working space when desired, alongside regular monthly in-person team meet-ups to collaborate, share ideas, and connect with your peers. Joining RMG's partner means having a direct voice in architectural decisions and delivering meaningful impact on an evolving platform that is transforming insurance technology.
