About the role

We're looking for a Full-Stack Engineer to develop and maintain our suite of transfer applications. You'll work across three repositories spanning React frontends and AWS serverless backends, contributing to feature delivery, bug fixes, and operational support across the full stack. We want someone who takes ownership of their work, shows initiative in solving problems, and can operate with autonomy once given direction.

Key Responsibilities

• Build and maintain features across transfer journeys
• Work across the full stack - React frontends, AWS Lambda BFF layers, and infrastructure as code
• Take ownership of issues end-to-end, from investigation through to production deployment
• Proactively identify and raise technical debt, bugs, and improvement opportunities
• Support and improve CI/CD pipelines and deployment processes
• Write well-tested, maintainable code with good coverage
• Collaborate with the wider team, platform teams, and product owners to deliver against requirements
• Participate in code reviews and contribute to team engineering standards

AWS & Infrastructure

• AWS CDK or SST for infrastructure as code
• Familiarity with core AWS services: Lambda, API Gateway, DynamoDB, IAM, VPC, SNS
• Basic understanding of VPC networking - Lambda in VPC, security groups
• Comfortable reading and modifying existing IaC stacks

Testing

• Unit and integration testing with Vitest or similar
• API mocking with MSW or equivalent
• A test-first or test-aware mindset

CI/CD & DevOps

• Experience with CI/CD pipelines (GitLab CI or similar)
• Comfortable deploying to multiple environments and debugging deployment issues

• Working in monorepo setups
• OAuth/token-based authentication flows

What We're Looking For Beyond Technical Skills

• Someone who takes ownership — when they pick up an issue, they see it through to completion
• Initiative to investigate and resolve problems without needing to be hand-held
• Comfortable asking questions and raising blockers early rather than getting stuck silently
• Willingness to work across unfamiliar parts of the codebase and learn on the job
• Good communication skills — able to explain what they're working on and flag risks to the team
• A growth mindset — keen to develop their skills across backend, infrastructure, and frontend
