Mission of this role

• Work on native development for hardware devices like RFID scanners and ports, including firmware-level programming.

• Manage your own backlog, prioritising effectively between immediate needs and long-term cleanups.

• Collaborate with teams across the company (financial, support, and our independent hardware branch, Geartracking), while reporting directly to Simon (CTO) initially.

• Make pragmatic “make-or-buy” decisions for tooling where needed.

Why this role?

• Impact you can see – Your work will directly improve daily workflows for colleagues.
