What this score means
Most of this role's work is still genuinely hard for AI to do. Physical presence, bodily skill, high-context judgment, direct human care - the things that don't translate to text.
If you're in this role, here's what to do now
You're not in the firing line today. But the frontier moves. Build enough AI fluency now that you can direct it for the parts of your work that could benefit. People in unexposed roles who understand AI become unusually valuable inside their organisations.
A meaningful slice of the task inventory is AI-reachable - the drafting, summarising, research and analysis parts especially. This role is at the point where the people who learn to direct AI well pull ahead of the people who don't.
If you're in this role, here's what to do now
Treat AI as a colleague you manage, not a tool you use. Identify the tasks where you'd describe the work to a capable junior - those are the tasks AI can do for you now. Spend your time on the judgment calls and the relationships instead.
Where a project with Alex usually starts for this role
This role's strict reading is low because its top tasks are judgment, not drafting. The three highest-stakes tasks below are still usually where we start — flip the toggle to 'With tools' to see what AI plus the right context can compress.
-
Test electrical circuits or components for continuity, using electrical test equipment.
-
Comply with all applicable standards, policies, or procedures, such as safety procedures or the maintenance of a clean work area.
-
Study blueprints, design specifications, or manufacturers' recommendations to ascertain the configuration of heating or cooling equipment components and to ensure the proper installation of components.
These are the highest-importance tasks AI can already handle when paired with the right tools and context. In a typical engagement the first wins come from building workflows around these — usually the difference between an LLM that can technically do the job and one that actually does it inside your business.
-
Study blueprints, design specifications, or manufacturers' recommendations to ascertain the configuration of heating or cooling equipment components and to ensure the proper installation of components.
-
Record and report time, materials, faults, deficiencies, or other unusual occurrences on work orders.
-
Keep records of repairs and replacements made and causes of malfunctions.
Every role has three or four wedges like these. Finding them takes an hour. Turning them into a workflow your team actually uses takes a few days. Talk to Alex about a project →

Methodology
This role's exposure score comes from Eloundou et al's 2023 GPT task labels, aggregated by O*NET importance within each O*NET-SOC code, then bridged to UK SOC 2020 via ISCO-08 (ONS Vol 2 coding index) and US SOC 2010 (BLS crosswalk). Employment and median pay come from ONS ASHE Table 14.7a, 2025 provisional. ASHE covers employees only, so self-employed workers are not counted.
