This job holds up well against AI
AI cannot yet do much of what this job actually involves, and the work is hands-on, in the real world. Software alone can't do it. That is about as safe as careers get right now, though it is still worth learning to use the tools well.

The role

As a heavy vehicle technician, you service and repair big vehicles like buses, HGVs, bulldozers and refuse trucks. You work in a garage or workshop, often on your own or with one or two other technicians. Using computer tools, you diagnose what is wrong with a vehicle, then take it apart and fix the problem - whether that is an engine leak, brake failure, or electrical fault.

The work is hands-on and physically demanding. You will spend time under lorries, in engine bays and in tight spaces, sometimes working in poor weather. You need to be very careful with safety and follow strict rules. Some jobs need real problem-solving - a technician might have only a vague description of a fault and needs to work it out through testing. The satisfaction comes from getting a big vehicle back on the road safe and ready for work. As you get more experienced, you might move into management or specialise in one type of vehicle, like hybrid engines.

Daily responsibilities

  • Diagnosing mechanical and electrical faults in heavy vehicles using advanced diagnostic tools.
  • Performing routine maintenance and repairs on a variety of large vehicles, including buses, trucks, and construction machinery.
  • Conducting safety inspections to ensure compliance with regulations and standards.
  • Collaborating with engineers and manufacturers to improve vehicle performance and reliability.
  • Keeping detailed records of repairs and maintenance work for compliance and warranty purposes.
  • Staying updated on the latest technologies and advancements in vehicle systems.
  • Advising customers on vehicle maintenance and repair needs.

AI EXPOSURE = the share of a job's day-to-day tasks AI can already do today, from the same exposure engine used across this site (Anthropic labour market research, 2026, observed real-world AI usage by occupation). Higher means more exposed. It is a measurement of now, not a prediction. THE DOOR = how hard the job is to get into, grade A (easy) to E (extremely hard), from each career's published forecast (OpenAI, "The AI Jobs Transition Framework", Richmond 2026, CC BY 4.0). A card marked MOAT NOT YET CLASSIFIED has a real exposure score but no entry yet in our moat register, so we make no claim about what structurally protects it. Scorecard grades and verdicts are Careermash editorial judgment: we show forecasts as forecasts and own our conclusions. Salary and pathway figures are each career's own published profile.
