Role Summary
We are looking for a Senior Infrastructure Engineer to help support, maintain and improve Reward’s core infrastructure.
This is a hands‑on role working across networks, firewalls, servers, Windows services, monitoring, backups and cloud‑connected infrastructure. You will be joining the Infrastructure Engineering team, contributing senior technical experience to the operation, maintenance and improvement of Reward’s core infrastructure services.
The role suits someone who enjoys practical infrastructure engineering, can troubleshoot complex issues, and is comfortable working across both physical and virtual environments. Some days may involve Wi‑Fi or wired network troubleshooting; others may involve server maintenance, backup checks, patching, data centre work, firewall changes, or building cloud environments using agreed standards.
This is not a desktop support role or a frontline SecOps role, although you will work closely with Desktop Engineering and SecOps where infrastructure overlaps.
What Success Looks Like
You will help keep Reward’s infrastructure stable, secure and well maintained. You will provide senior technical support across networks, servers, Windows services and infrastructure platforms, contribute to improvement projects, and help the team improve its documentation, monitoring, patching, backup and operational processes.
You will be expected to bring good judgement, take responsibility of your work, and help improve the reliability of the infrastructure services that support Reward’s business.
