Working closely with Engineering Leads, Product Managers, Designers, QA and frontend engineers, you will deliver reliable, secure and scalable solutions across our internal and third-party systems.

This is a hands-on engineering role, with opportunities available at both mid and senior level. The level of appointment will reflect your experience, technical capability and the level of ownership you are ready to take.

The Role

• Design, build and maintain backend services, APIs and integration solutions using C#, .NET and Microsoft Azure.
• Connect our mobile applications and digital products with internal platforms and third-party systems.
• Develop secure, scalable and maintainable solutions using API-led and event-driven integration patterns.
• Work with Product, QA and frontend engineers to deliver high-quality features from design through to release.
• Write clean, testable code and contribute to code reviews and engineering standards.
• Troubleshoot integration failures, production issues and performance problems.
• Improve automated testing, CI/CD, monitoring and system observability.
