**Responsibilities**

- Enablement & AI Tooling: Design, build, research, evaluate and adopt advanced engineering tools, including leveraging Agentic AI for the automated triage of performance test failures, automated test-code generation, and eliminating developer toil.

- Governance & Observability: Develop and integrate quantitative product reliability metrics for test coverage, execution speed and defect prevention, into CI/CD pipelines.

- Drive Quality Engineering Initiatives: Partner with engineering teams to conduct risk analyses, implement integration and performance testing strategies, and resolve complex edge-case defects.

- Backend Engineering Delivery: Develop high-quality, testable, and robust backend services, APIs, and microservices in alignment with architecture standards.

**Requirements**

- Extensive hands-on experience in backend software development using modern languages (e.g., Go, Python) and cloud-native architecture.

- Proven track record of designing and implementing scalable backend platforms, with deep expertise in CI/CD integration, containerisation, and orchestration (e.g., GitHub Actions, GitLab CI, Docker, Kubernetes).

- Deep understanding of complex distributed systems, API protocols (REST/gRPC), and observability stacks (e.g., Prometheus, Grafana, BigQuery).

- Familiarity with leveraging modern AI-assisted tools and building agentic workflows for code generation, log analysis, and automated triage.

- Excellent communication and stakeholder management skills to advocate for quality initiatives and influence cross-functional technical teams.

**Benefits**

- Highly competitive salary
