HV Mechanic

United Autosports – McLaren Hypercar Programme
Full-time, travelling role

Are you an experienced High Voltage Mechanic looking to work at the cutting edge of global motorsport? Do you thrive in high-pressure environments where precision, safety and technical discipline genuinely matter? If so, you could be the next High Voltage Mechanic on our McLaren Hypercar Programme.

As our High Voltage Mechanic, you will take ownership of the most safety-critical systems on the car. This includes the hybrid system, energy storage, HV cabling, inverters, interlocks, safety circuits, and all associated procedures. You will work across car build, testing and race events to ensure these systems are safe, compliant, and performing at their peak.

This is not an entry-level position. You’ll be one of the few people authorised to work hands‑on with HV systems, making your judgement, discipline, and professionalism absolutely essential.

• 
  
• Leading HV activation, charging, shutdown and isolation procedures.
  
• Managing lock‑out/tag‑out, interlock checks, PPE use, and safe working zones.
  
• Working directly with the manufacturer’s hybrid engineers to maintain system integrity.
  
• Conducting inspections, testing and condition checks on battery, inverter and hybrid components.
  
• Supporting mechanical build where HV integration is required (cables, cooling, insulation checks).
  
• Fault finding, responding to HV alarms, and following emergency response protocols.
  
• Maintaining HV tooling, calibrations, signage and documentation.
  
• Ensuring all regulatory, safety and manufacturer protocols are executed with absolute precision.
  
• Providing technical oversight during events where live hybrid systems present real risk.
  

• 
  
• Significant experience working with HV/hybrid systems in motorsport or a highly technical environment.
  
• Formal HV certification (Level 3 minimum or equivalent manufacturer/FIA‑approved training).
  
• Outstanding discipline, calmness and procedure‑led thinking.
  
• Ability to manage risk, respond professionally under pressure and work safely in live environments.
  
• Strong communication, teamwork and situational awareness in a fast-moving garage environment.
  

If you want to work in a role where your technical ability is genuinely mission‑critical, where precision matters and where you’ll be trusted with systems that few people can touch — this is the opportunity.
