Job description

Key responsibilities:

• Anchor the portfolio technically: Own the technical health of All Ears and the supporting products across multiple languages and codebases, from legacy to modern stacks.
• Maintain and support: Deliver bug fixes, security patches, infrastructure upkeep, L2 and L3 support, and monitoring across the portfolio.
• Lead migrations: Complete the All Ears v2 migration and retire the legacy codebase, and decide and coordinate adaptations for planned work such as the TCI and Connectogram migrations to Teachers Workspace.
• Set standards and mentor: Define and enforce code review, testing, and release practices, and guide the Consultant engineer through review and pairing.
• Keep it maintainable: Keep runbooks, architecture notes, and handover material current so the products stay maintainable and transferable.
• Coordinate across teams: Work with GovTech engineers, product staff, and MOE stakeholders to align on priorities, risks, and delivery.

What we are looking for:

• Experience: Minimum 7 years of hands-on full stack software engineering, including a senior or lead role.
• Languages and frameworks: Strong proficiency with a modern JavaScript or TypeScript framework (React), backend APIs and services, and relational databases (PostgreSQL). Proven ability to navigate, debug, and change code across several languages, codebases, and legacy systems.
• Architecture : Make sound design and architecture decisions, and reason about tradeoffs in a maintenance and migration context.
• Cloud and infrastructure: Solid knowledge of cloud-hosted applications, containerised deployments (Docker), and CI/CD pipelines.
• Observability and troubleshooting: Analyse logs and metrics using AWS tools such as ECS and CloudWatch, and OpenTelemetry for tracing, metrics, and logs.
• Version control and code review: Strong practice with Git and quality gates, and experience setting review standards.
• Software lifecycle: Deep understanding of the software development lifecycle and Agile delivery on product-centric teams.
• Security-aware: Attention to secure coding practices and awareness of government security and compliance requirements.
• Coordination: Experience coordinating cross-team work and guiding less senior engineers.

Nice to have:

• Government domain: Familiarity with government or public‑sector delivery contexts.

Personal attributes:

• Self-directed: A driven, resourceful engineer who can pick up unfamiliar codebases quickly and lead without close direction.
• Pragmatic: Balances speed and quality and makes sensible tradeoffs in a maintenance context.
• Comfortable with ambiguity: Navigates shifting priorities as products transition, sunset, or transfer.
• Collaborative: Builds good working relationships with stakeholders, teammates, and vendors, and influences across teams.
• Ownership: Takes responsibility for the stability, quality, and technical direction of the products in their care.
