- Contribute to infrastructure services design, including load balancers, firewalls, DNS, NTP, AAA, and related components.
- Ensure infrastructure environments are optimised, scalable, and aligned with sustainability goals, including hardware efficiency.
- Deliver end‑to‑end design documentation, including blueprints, runbooks, test plans, and acceptance criteria.
- Oversee supplier deliverables to ensure compliance with architectural standards and design specifications.
- Support storage design and integration, including evaluation of CSI and solutions such as Pure Storage.
