Do Work That Matters

Join the Insurance and Retail Partnerships crew within Wealth and Private and help shape digital experiences that make a difference for customers.

As a Staff Software Engineer, you’ll combine hands-on engineering with technical leadership to build and evolve our home insurance technology and application journey. From intuitive digital experiences through to secure and resilient backend integrations, you’ll help create solutions that are reliable, performant and simple for customers to use.

You’ll have the opportunity to solve complex problems at significant scale while helping shape engineering practices and the future direction of our technology.

See yourself in our team

You’ll join a high-performing engineering team within Insurance and Retail Partnerships, where we own the home insurance code and application journey end to end.

Working in a full-cycle engineering model, you’ll take ownership from solution design through development and production. You’ll partner closely with engineers, the Product Owner and Crew Tech Lead to:

• Design and build scalable full-stack solutions across customer-facing applications and backend services.
• Remain hands‑on with C#, .NET/.NET Core, APIs and modern frontend technologies including React or Angular.
• Shape microservices, event‑driven architecture and engineering patterns that improve reliability, security and performance.
• Lead technical discussions and influence solution design and technology decisions.
• Apply DevSecOps principles across build, deployment, monitoring and ongoing production ownership.
• Mentor engineers, share knowledge and strengthen engineering capability across the team.
• Experiment with emerging technologies and develop proofs of concept that can improve customer and engineering outcomes.
• Champion continuous improvement, engineering excellence and customer‑focused technology.

We’re interested in hearing from people who:

You’re an experienced full-stack engineer who enjoys remaining close to the technology while providing technical leadership to others. You can turn complex problems into practical solutions, influence stakeholders and help engineers grow while maintaining strong engineering standards.

Experience across several of the following will set you up for success:

• Strong C# and .NET experience, including .NET Core/.NET Framework, REST APIs, MVC, microservices, object‑oriented programming and design patterns.
• Frontend development experience with React or Angular, JavaScript, HTML and CSS, with an interest in broadening your capability across modern frameworks such as Next.js.
• Experience designing distributed or event‑driven systems, including technologies such as Kafka.
• AWS cloud engineering and containerisation experience using Docker.
• CI/CD and DevSecOps experience using tools such as GitHub Actions, TeamCity, Jenkins or Octopus Deploy.
• Experience with relational or NoSQL databases such as Microsoft SQL Server, Oracle or MongoDB, plus monitoring and observability platforms such as Grafana, Prometheus, Splunk or Observe.
• Demonstrated ability to lead technical initiatives, influence stakeholders and mentor engineers in an Agile engineering environment.
