We are looking for two Technical Engineers with experience to join our IT team, helping to deploy, configure and support our technical products and infrastructure. 

This is a varied, hands-on role covering application deployment, troubleshooting, SQL Server, APIs, Windows and Linux environments, networking and technical integrations. 

You’ll work closely with our Infrastructure, Development, Technical Support and Project teams to deliver reliable and secure solutions for both customers and internal teams. 

What you'll do 

  • Install, configure and upgrade our applications remotely and on customer sites.

  • Support wider infrastructure and technical delivery projects across the business. 

This role would suit an experienced engineer who enjoys understanding how systems work, investigating technical problems and taking ownership of issues through to resolution. 

You’ll have the opportunity to work across a broad range of technologies and continue developing your knowledge across infrastructure, applications, databases, networking and cybersecurity.
