Lead Java Engineer

Responsibilities

• Own solution architecture for a busy, multi-tenant platform in which a single user action may affect hundreds of thousands of records, including the data model, transaction boundaries, batching strategy and failure behaviour.
• Remain accountable for those architectural decisions once they are operating in production.
• Contribute production Java code daily within a large, established codebase built on modern Java and Spring Boot.
• Establish and enforce performance standards supported by measurement rather than assertion, covering query plans, batched writes, memory behaviour and lock contention.
• Raise the engineering standard across the team through code review, pairing, and written design documentation.
• Diagnose production issues independently using logs, traces and metrics, and establish root cause before escalating.
• Apply AI-assisted tooling where it demonstrably improves design exploration, code generation, refactoring and debugging, and recognise where it does not.
• Set the technical direction of the systems you own.
• Who This Role Is Not For
• This role is unlikely to suit you if
