Contribute to the design and maintenance of component libraries and design systems. Collaborate with UX/UI designers to ensure implementation aligns with design intent. Lead front-end projects and provide technical direction and mentoring to less experienced developers. Support continuous integration and delivery using AWS-native tools such as Amplify and CodePipeline. Participate in code reviews and cross-functional Agile ceremonies.

Requirements

Strong experience with JavaScript frameworks, particularly React or Angular. Demonstrated ability to consume and integrate APIs within complex applications.

Familiarity with front-end CI/CD tools and AWS-native deployment mechanisms. Understanding of accessibility standards, front-end security, and performance optimisation. Experience participating in Agile delivery teams and collaborative software environments.

Desirable Experience:

2-6 years of front-end development experience in commercial environments. 2+ years working with AWS-based front-end delivery (e.g., Amplify, CloudFront, Cognito integration).
