This role is with a growing technology consultancy. This is a hands-on principal engineering role: architecture ownership across multiple services, technical leadership across teams, and direct contribution to engineering standards and hiring. The successful candidate will be writing code as well as setting direction - this is not a purely architectural or management position. Current delivery is a Java/Spring Boot microservices platform on AWS EKS, with a Next.js frontend and Camunda-based process orchestration.
Essential
- Experience level: 10+ years minimum, principal or staff grade equivalent.
- Backend and cloud:
- Java 17 or 21, at expert level - modern language features
- Spring Boot in depth: security, transaction management, async/reactive
- Microservices architecture design - has designed services from scratch
- Kubernetes and Docker in production (not local development use)
- AWS, hands-on: EKS, Lambda, S3, RDS, EventBridge
- CI/CD pipeline ownership
- Automated testing discipline: JUnit, Mockito, integration testing, TDD or BDD
- Frontend:
- Held a lead or tech lead role on frontend development in React. Leadership must have been over React work itself.
- Understands and has implemented FFE/BFE separation - the split between the presentation layer (components, styling, client state) and the frontend's own server-side tier (data aggregation for the UI, session and auth handling, server-side rendering, API route composition).
- Leadership:
- Architecture ownership across multiple systems
- Cross-team technical leadership
- Track record of influencing engineering standards, technology choices, or hiring
- Evidence of growing other engineers
- Security clearance: UK SC clearance required. Active clearance strongly preferred; eligible candidates considered - must be a UK national with 5+ years continuous UK residency.
Desirable
- Camunda 8 / BPMN process orchestration
- Next.js specifically (App Router, server components, route handlers)
- Terraform or other infrastructure-as-code, to module-authoring level
- React Native or equivalent — building native mobile from a React codebase
- Design system or component library ownership
- Consultancy or client-facing delivery background
- Open-source contributions, conference talks, or published technical writing
- Polyglot beyond Java
NB: for non-UK Citizens; we cannot accept applications from anyone requiring sponsorship (now or in the future) for UK permanent employment status. If you are utilising a work visa this must allow you to work in the UK unrestricted for at least the next 5 years.
