- Establish reliable sources of truth for infrastructure, services, customers, environments, ownership, and configuration.
- Drive prioritisation, backlog management, technical design discussions, delivery, and adoption.
- Define success metrics and ensure tooling is secure, observable, auditable, reliable, and well documented.
- Evaluate build vs. buy decisions and third-party tooling where appropriate.
Qualifications:
