We are looking for enthusiastic and inquisitive Software Engineers with a passion for building modern, modular, and high-performing frontend applications. This role focuses on the design, delivery, and maintenance of micro frontend (MFE) architectures, enabling scalable and independently deployable user experiences across our platforms.  

You will work extensively with React, NestJS, and related technologies, contributing to both frontend and backend-for-frontend (BFF) solutions. With a DevSecOps mindset, you will build secure, performant, and resilient applications using modern software engineering practices, automation, and continuous improvement. 

You will collaborate with cross-functional teams to deliver innovative products that meet our clients' needs.

• Design and implement scalable and modular frontend solutions using micro frontend architecture and module federation. 
• Develop applications using React, TypeScript, and NestJS, supporting robust client-server integration. 
• Build and maintain CI/CD pipelines that support independently deployable frontend modules with strong testing and release automation. 
• Ensure applications meet performance, security, and accessibility standards, including support for lazy loading, code splitting, and caching strategies. 
• Use GenAI tools responsibly to support software design, delivery, problem solving and developer productivity, while maintaining strong engineering judgement, quality and security standards. 
• Contribute towards end-to-end testing strategies, ensuring comprehensive test coverage across the stack. 
• Actively contribute to Agile ceremonies and delivery processes, taking ownership of outcomes and blockers.

Collaboration & Communication 

• Work closely with designers, engineers, and product teams to deliver cohesive and consistent user interfaces across MFEs. 
• Collaborate with architecture and platform teams to ensure alignment with cross-cutting concerns such as routing, authentication, and shared libraries. 
• Champion a collaborative engineering culture through Chapters, Squads, and Guilds. 
• Communicate complex technical decisions clearly across technical and non-technical stakeholders. 

Experience Required 

Essential skills and experience 

• Strong experience in a Software Engineer role, ideally delivering modern web applications.

• 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. 

Nice to have 

• Experience designing and building micro frontend architectures, including module federation and independently deployable services. 
• 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 learning about, GenAI tools to improve engineering effectiveness, collaboration and delivery outcomes.
