Job Summary

Build secure, testable and observable services that power Treasury capabilities.

 

Role accountabilities

• Develop back-end services using Java/Quarkus, Node.js or another agreed strategic technology based on the use case.
• Implement secure API layers and service contracts supporting presentation, orchestration, domain and system integration.
• Build for Cloud Run or agreed GCP runtimes with appropriate configuration, scaling and failure handling.
• Integrate with BigQuery, Cloud SQL, data products, events and specialist calculation services.
• Create automated unit, component, contract and integration tests and support end-to-end quality engineering.
• Instrument services with logging, metrics, tracing and actionable alerts.
• Apply secure coding, IAM, secrets, encryption, audit and least-privilege controls.
• Contribute to design, estimation, code review, CI/CD, production support and continuous improvement.

Core skills and experience

• Strong Java and modern service-framework experience; Quarkus experience preferred.
• REST/API design, versioning, error handling, idempotency and contract testing.
• Cloud-native engineering on GCP, containers and managed runtimes.
• SQL and data-access patterns for analytical and operational stores.
• Event-driven design and integration technologies such as Kafka and API management such as Apigee X.
• Automated testing, code quality, dependency management and observability.
• Performance, resilience, security and operability engineering.

Leadership expectations

• Take ownership beyond assigned tickets, from clarification through safe operation.
• Lead technical slices, mentor peers and raise concerns early.
• Use reviews and pairing to improve collective code ownership.
• Work constructively with architects, UI, data, QE and DevOps colleagues.
• Make maintainability and operational impact visible in delivery decisions.

Productivity and delivery expectations

• Deliver small, demonstrable increments with clear acceptance criteria and automated evidence.
• Minimise hand-offs by building, testing, documenting and supporting services as one team.
• Use automation and reusable components to improve flow without trading away quality.
• Track lead time, escaped defects, failed changes, reliability and rework as learning signals, not individual scorecards.

Expected behaviours

• Proactive ownership and bias to action.
• Engineering discipline and respect for controls.
• Open collaboration, constructive challenge and timely communication.
• Customer and outcome focus.
• Continuous learning and willingness to simplify.

Evidence of effectiveness

• Working services meeting functional and non-functional acceptance criteria.
• High automated test coverage appropriate to risk and stable pipelines.
• Clear API contracts, operational runbooks and observable production behaviour.
• Low avoidable rework and active contribution to team improvements.

Desirable domain experience

• Regulated or financial-services engineering.
• Treasury calculations, workflows or specialist engine integration.
• mTLS, Apigee X, Kafka and GCP production operations.
