This track demands a developer who champions resilient code quality and values automated testing pipelines. You will take full ownership of your shipping pipelines, reduce technical debt, participate in production on-call rotations, and directly influence platform roadmap priorities.

• Automated Test Engineering: Formulate and enforce thorough automated testing strategies, writing unit and integration tests via Playwright, Vitest, and Cypress systems.
• CI/CD Workflow Management: Deploy software features continuously into cloud systems using automated pipelines, managing environments across Buildkite, GitHub, and Jira.
• On-Call System Triage: Take clear ownership of production software health, resolving incidents, participating in standard on-call rotations, and leading root-cause analyses.
• Agile Collaboration: Participate actively in backlog refinements, team code reviews, sprint planning sessions, and system design evaluations alongside Product leadership.
• Platform Performance Optimization: Refactor codebase components systematically to reduce architectural code debt and ensure features comply with strict performance standards.

• Solid conceptual understanding of automated software verification, cloud continuous delivery pipelines, and secure engineering practices.
• Proven capacity to independently triage, debug, and resolve runtime production data or application exceptions.
• Location Context: 100% remote-first operational infrastructure flexibility restricted exclusively to qualified developers permanently based in the United Kingdom.

Preferred Strategic Indicators (Nice to Have)

• Prior production exposure utilizing public cloud infrastructure systems, specifically Amazon Web Services (AWS) platforms.
• Familiarity running data monitoring systems and dashboard observability tools such as DataDog and Grafana.
• A Bachelor’s degree in Computer Science, Software Engineering, or equivalent practical enterprise experience.
