The Role
This isn't a "keep-the-lights-on" job - this is a run-the-site-like-you-own-it role.
As a Supervisor Tech 6 - Critical Facilities Engineer, you're the go-to expert when things get complex. You work independently, take ownership of the most challenging technical issues, and help shape how the site operates - not just how problems are fixed.
You'll lead by expertise, not titles. When systems fail, projects land, or procedures need re-thinking, you're the person others turn to.
What You'll Be Doing
Keep the Heart of the Site Running
- Own complex preventative and corrective maintenance across critical electrical and mechanical systems.
- Lead the technical response during major incidents, outages, and high-risk activities.
- Monitor and act on BMS alarms that require deep technical judgment and fast, independent decision-making.
- Solve advanced issues - and turn lessons learned into better procedures for everyone.
- Inspect and oversee life-safety systems, fire suppression, plumbing, and critical infrastructure.
- Spot opportunities to improve energy efficiency, resilience, and reliability.
- Help define the scope for lifecycle replacements, end-of-life equipment, and critical upgrades.
Be the Trusted Technical Lead (Vendors & Projects)- Help select, guide, and oversee vendors working on critical systems.
- Make sure high-risk work is done safely, correctly, and to standard.
- Create and review MOPs, scripts, and technical documentation before work starts.
- Control the full work approval process - from pre-job briefings to final sign-off.
- Ensure drawings, technical files, and plant documentation stay accurate and up to date.
Step Up When It Matters Most- Complete and review complex site logs, permits, and operational documentation.
- Identify Single Points of Failure and push improvements before they become incidents.
- Support the team in following operating procedures - and help improve them where they don't work.
- Be on the front line during critical incidents, major failures, and urgent escalations.
- Support Root Cause Analysis (RCA) and help drive real, lasting fixes.
- Work closely with management to maintain strong, practical technical standards.
Projects, Capacity & Continuous Improvement- Deliver high-skill work orders, complex installations, and infrastructure changes.
- Lead advanced troubleshooting to keep downtime to a minimum.
- Contribute to capacity planning and risk reviews.
- Lead infrastructure project activities from planning through execution.
- Make controlled changes to mechanical, electrical, and specialist systems where required.
Work Like a Senior Engineer Should- Collaborate across teams to solve difficult, system-level problems, not just symptoms.
- Act as a technical escalation point for component-level failures and rare issues.
- coach and advise other engineers - sharing expertise and practical know-how.
- Plan and manage inventory for critical spares and equipment so the site is always ready.
- Lead technically complex initiatives that raise the bar for how the site operates.
What You Bring- Extensive hands-on experience in critical facilities, data centers, or similar mission-critical environments.
- A track record of working independently on complex systems and making sound decisions under pressure.
- Strong electrical and mechanical troubleshooting skills.
- Confidence to lead during incidents, challenge processes, and improve how work gets done.
- A practical, calm approach - especially when things don't go to plan.
Education:- Typically a Bachelor degree in electrical or mechanical Engineering, German Meister degree, or similar, plus significant relevant experience.
