- Evaluate and recommend new technologies to improve reliability, efficiency, and security.
- Identify dependencies and potential single points of failure, and implement mitigation strategies.
- Maintain visibility over the entire UK IT environment, while being ready to dive in and resolve critical issues.
Qualifications
- Proven experience as a Sysadmin / Systems Engineer covering multiple IT domains: networking, servers, endpoints, IAM, support, and SaaS tooling.
- Hands‑on experience with Okta (or similar), Google Workspace, endpoint management systems, and server environments.
- Experience in regulated or high-security environments is a strong advantage.
