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.

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.
