About the role
We’re looking for a Senior Full‑Stack Engineer to develop and maintain our suite of transfer applications. You'll work across various repositories spanning React frontends and AWS serverless backends, owning the full delivery lifecycle from feature development through to production. Critically, we want someone who can help drive the technical strategy and continuous improvement of these applications, aligning with broader company engineering standards and platform direction.
Key Responsibilities
- Develop and maintain multi‑step transfer journeys across transfer products.
- Own the full stack; React frontends, AWS Lambda BFF layers, and IaC.
- Drive technical strategy for the transfers domain, proposing and delivering improvements that align with company‑wide engineering direction.
- Champion continuous improvement; identify tech debt, propose modernisation, and improve developer experience.
- Contribute to architectural decisions around API design, infrastructure patterns, and cross‑service integration.
- Collaborate with platform/infrastructure teams to evolve integration patterns.
- Support CI/CD pipelines and deployment processes across all environments (dev, staging, production).
- Mentor other engineers and contribute to team‑wide engineering standards.
Required Skills
- Testcontainers experience is a plus.
- CI/CD multi‑stage, environment‑specific deployments, automated security scanning (Snyk or similar SAST/DAST), environment promotion strategies (dev → staging → production).
- General: Monorepo experience (pnpm workspaces, npm workspaces), feature flagging (LaunchDarkly or similar), OAuth/token‑based authentication and authorisation flows, strong understanding of cross‑account AWS patterns.
Desirable
- Frontend React (v18+) with TypeScript, React Hook Form, Zod/schema‑based validation, TanStack Query (React Query) for server state management, Vite build tooling, component library integration, accessibility‑first development.
- Playwright for end‑to‑end and snapshot testing, contract testing (Pact), analytics integration (Adobe Analytics or similar).
Other
- Experience with SST v2, familiarity with API gateway/ingress platforms, experience with Cognito for machine‑to‑machine auth, financial services domain experience, driving technical roadmaps and aligning them with broader organisational strategy.
What We're Looking For Beyond Technical Skills
- Someone who proactively identifies opportunities for improvement rather than waiting to be told.
- Ability to articulate technical trade‑offs and influence direction at a team and cross‑team level.
- A pragmatic approach, balancing ideal solutions with delivery timelines.
- Comfort working across codebases with different maturity levels and patterns (SST monorepo vs CDK + separate front‑end).
- Strong communication skills for collaborating with platform teams, product owners, and other squads.
