IT Support Engineer

At Mustard Systems, technology underpins everything we do. From our trading systems and development platforms to the day-to-day tools used by our teams, reliable IT services are essential to keeping the business running smoothly.

We're looking for an IT Support Engineer to provide exceptional technical support across the business. This is a hands-on role where you'll be responsible for maintaining end-user systems, office infrastructure, and internal services, ensuring our staff can work efficiently and without disruption.

This role is particularly well suited to someone who sees IT Support as the foundation of a longer-term career in systems administration, infrastructure, or platform engineering. You'll gain exposure to a broad range of technologies and business-critical systems, working closely with experienced engineers while developing a deep understanding of how technology supports our operation.

We're looking for someone who is naturally curious, eager to learn, and interested in building long-term expertise rather than simply resolving tickets. As your knowledge and capabilities grow, you'll have opportunities to take on increasingly complex technical responsibilities across our infrastructure and internal systems.

You'll be joining a collaborative IT team that values automation, continuous improvement, and practical solutions. While your primary focus will be supporting users and maintaining operational excellence, you'll also have opportunities to develop skills across infrastructure, systems engineering, and automation as the role evolves.
