Aboutthe Role
A hands‑on systems engineering role supporting enterprise IoT deployments alongside broader infrastructure work. This is not a Windows admin or L1 support position—the client needs L2 to early L3 depth across devices, networks, servers, and SaaS platforms.
You’ll be involved in device configuration, patch testing, rollout activities, and troubleshooting across a mixed environment that includes IoT systems (building management, lighting, occupancy, air quality), Windows and Linux servers, and cloud/SaaS platforms.
Requirements
What You'll Be Doing
- Supporting and implementing enterprise IoT/OT device infrastructure — config, maintenance, patching, troubleshooting

- Performing patch testing, deployments, and device validation
- Troubleshooting complex issues across device, network, server, and platform layers
- Managing migration, refurbishment, and new IoT platform rollout projects
- Writing and maintaining runbooks, technical documentation, and operational guides
- Ensuring compliance with enterprise security standards — auth, authorisation, encryption
- Working with vendors and stakeholders to implement and future‑proof systems
What We Need
- Windows and Linux server administration
- IoT/OT device configuration, troubleshooting, and support across multiple platforms
- SaaS platform experience, including SAML and OIDC
- Security fundamentals: authentication, authorisation, encryption
- Strong documentation skills — clear, maintainable, and auditable
- Comfortable in a high‑security, production enterprise environment
