Technical Operational Support Manager

Summary

At Acorn, we don’t just offer jobs, we build careers. For over 40 years, we’ve been trusted to deliver market-leading engineering and compliance services across London and the Southeast. Our success is built on investing in our people, and many of our team members have progressed from entry-level roles to senior positions through our structured development programs.

This role supports an individual transitioning from a technical position into a leadership and management role, with a strong emphasis on electrically‑biased engineering expertise.

The Technical Operational Support Manager will work in our Oxford based site with the possible introduction of a Cambridge site, supporting the Contract Manager in delivering a safe, compliant, and high‑quality service that meets both client and Acorn expectations.

You will work closely with the Contract Manager, site teams, and subcontractor partners to ensure Acorn values, behaviours, and operational excellence are upheld across both locations.
