- Are comfortable navigating ambiguity and guiding teams through architectural and technical decisions.
- Think in systems, not just services — considering performance, resilience, security, operability, and cost.
- Communicate clearly and confidently across both technical and non‑technical audiences.
- Take ownership and accountability for outcomes, not just output.
- Are passionate about mentoring others and growing engineering capability.
- Continuously challenge the status quo in pursuit of better solutions. Tech Skills We use a broad range of tools, languages, and frameworks. We don’t expect you to know them all but experience or exposure with some of these (or equivalents) will set you up for success in this team:
- Backend & APIs : Deep expertise in Java, Spring Boot, and designing high‑quality RESTful APIs (performance, security, versioning, resilience).
- Cloud platforms : Proven experience designing and operating cloud‑native architectures on AWS (e.g., S3, ECS, Lambda, API Gateway, CloudWatch).
- Frontend & services : Experience with modern frontend or service runtimes such as React or Angular, Node.js, TypeScript, Express/Fastify, or NestJS.
- Data & processing : Exposure to Python, SQL, Spark, or Scala for data‑intensive or distributed workloads.
- DevSecOps & CI/CD : Ownership of build, test, and release pipelines using GitHub Actions, ArgoCD, or similar tooling.
- Testing & quality : Strong understanding of automated testing strategies and frameworks (e.g., BDD, Playwright, Selenium).
- Containers & orchestration : Experience with Docker and Kubernetes in production environments.
- Security : Solid understanding of authentication and authorisation patterns (OAuth2, JWT) and secure API design.
- Engineering excellence : Familiarity with design systems, accessibility standards, monitoring, and performance optimisation.
