Senior Software Engineer

This is an exciting opportunity for an experienced engineer to help shape modern digital experiences at scale. You will play a central role in designing and delivering modular, high-performance applications using React, TypeScript and backend-for-frontend patterns in a fast-paced environment, while helping to strengthen engineering standards across the team. 

You will work across micro frontends, scalable platform architecture, secure engineering practices, continuous delivery and AI-enabled engineering in a collaborative environment. This is a hands-on senior role where you’ll help improve reliability, quality and maintainability, while mentoring other engineers and contributing to the evolution of our engineering practices. 

What you'll be doing

• Design and build scalable, modular applications using React, TypeScript and micro frontend architecture. 
• Develop backend-for-frontend services with NestJS to support seamless client and server integration. 
• Improve engineering quality through modern CI/CD, automated testing, automation and secure development practices. 
• Collaborate with engineers, architects, product and platform teams to solve complex delivery and integration challenges. 
• Mentor other engineers, share knowledge, and help drive continuous improvement across the team. 
• Use GenAI tools responsibly to support software design, delivery, problem solving and developer productivity, while maintaining strong engineering judgement, quality and security standards. 

What we're looking for

Essential skills and experience 

• Strong experience in a Senior Software Engineer role, ideally delivering modern web applications. 
• Hands-on expertise in React and TypeScript, including component design, state management and performance optimisation. 
• Experience designing and building micro frontend architectures, including module federation and independently deployable services. 
• Experience with NestJS and backend-for-frontend patterns. 
• Good knowledge of CI/CD, automated testing and modern software delivery practices. 
• Understanding of secure engineering principles, web security best practices and resilient application design. 
• Strong collaboration and communication skills, with experience mentoring and supporting other engineers. 

Nice to have 

• Experience with cloud-native environments such as GCP or Azure. 
• Familiarity with OAuth2, OpenID Connect, SAML or similar authentication and authorisation approaches. 
• Experience with Docker, Kubernetes, Helm, Terraform or related tooling. 
• A proactive approach to continuous improvement, knowledge sharing and raising engineering standards. 
• Experience using, or enthusiasm for using, GenAI tools to improve engineering effectiveness, collaboration and delivery outcomes. 

What will help you succeed in this role

• Proactive and adaptable in a fast-paced engineering environment.
• Self-driven, with strong ownership and delivery focus.
• Collaborative and supportive, with a mentoring mindset.
• Pragmatic, curious, eager to learn, with the ability to break down and solve complex problems. 
• Committed to continuous improvement in engineering quality and delivery.
• Passionate about GenAI.

If this role excites you but your experience doesn’t align perfectly with every requirement, we’d still love to hear from you.
