What You'll Do

Mark43 is seeking a hands-on Lead Support Engineer to lead our growing UK Support team, which supports mission-critical public safety systems for customers including Greater Manchester Police (GMP).

This role combines people leadership with active participation in day-to-day technical support. You will manage a team of Junior Support Engineers and Support Engineers while remaining closely involved in the support queue—responding to tickets, conducting initial triage, setting priorities, delegating work, and supporting complex investigations.

You will be responsible for ensuring that customer issues are handled efficiently, professionally, and in line with agreed service levels. You will also act as an escalation point for critical P0 and P1 incidents and participate in an on-call rota.

The successful candidate will be a confident people manager with a strong technical support background. You should be comfortable switching between coaching team members, coordinating incident response, communicating with customers, and investigating technical issues directly.
