  • Provides technical guidance to engineering and business partners, acting as a subject matter expert in relevant application, service or integration domains.
  • Leads the technical delivery of complex changes through implementation, testing, integration, controlled migration, release readiness and operational support.
  • Applies enterprise-authorised coding agents and automation across design, implementation, testing, review and troubleshooting, creating reusable context, tools and workflows.
  • Drives effective team adoption of approved AI-assisted engineering practices, validating generated changes through peer review and independent tests for correctness, performance and security, and coaching others on safe use.
  • Works closely with business, Product, Design, web and mobile partners to clarify client needs, interpret financial workflows and translate agreed requirements into practical technical solutions.
  • Improves engineering standards, automation, observability and resilience for owned services, escalating material risks and cross-domain decisions to the appropriate engineering or control owner.

  • Strong Java/JVM, API, distributed-systems and data-modelling skills, with practical experience of reliable service integration and robust failure handling.
  • Ability to solve complex design and functionality problems independently with limited oversight, explain technical trade-offs and recognise when wider decisions require alignment or escalation.
  • Practical cloud native experience on AWS or a comparable platform, including automated delivery, testing, observability and production support.
  • Demonstrated effective use of enterprise-authorised coding agents beyond basic code completion, with concrete examples of implementation, review, test acceleration or troubleshooting and how outputs were verified.

  • Expertise in Computer Science, Computer Engineering, Mathematics, or a related technical field.
  • Public GitHub repositories or substantive open-source contributions demonstrating your own hands-on engineering work, with the ability to explain relevant code, design decisions, testing and outcomes.
  • Evidence of curiosity and self-directed learning beyond routine delivery, demonstrated through prototypes, open-source work, technical experiments or reusable engineering tools.
  • Effective technical leadership, mentoring and business communication, with the ability to understand client and financial workflows and work constructively across teams and locations.
