The robots did not take their jobs. They changed the jobs so much that people walked out. That is how AI changing UK STEM jobs looks in 2026.
AI changing UK STEM jobs is no longer a forecast. A new YouGov survey for recruiter SThree found that 15% of UK scientists and engineers saw colleagues leave in the past year because AI changed their work. In addition, almost half say their employer struggled to replace the specialists who left.
AI Changing UK STEM Jobs: What the SThree Survey Found
SThree, a workforce consultancy for science and engineering, published the findings on October 20, 2026. YouGov ran the online survey between July 10 and September 1, 2026.
The full study covers 4,126 STEM employees in five countries: the UK, the Netherlands, Germany, the US and Japan. The UK sample was 885 people, according to Laboratory News.
Notably, the headline is about people leaving, not robots arriving. Across all five countries, one in six respondents saw colleagues quit after AI changed their work “beyond recognition,” SThree said.
Scientists and Engineers Leaving Jobs Changed by AI
Why would a skilled engineer quit over a tool? For example, the survey points to three reasons.
First, the work itself changed. Second, about one in seven saw colleagues leave because AI cut their career progression. Third, roughly one in eight blamed unsustainable workloads.
SThree CEO Timo Lehne put it bluntly: “Competition for specialist STEM skills is already intense.” He added that experienced people who no longer see the work or progression they signed up for can take their expertise elsewhere.
Meanwhile, 37% of UK respondents think their organisation is adopting AI too quickly to weigh the impact on roles.
UK vs Global: The STEM Workforce Report 2026 in Numbers
On the whole, the UK figures sit close to the five-country average. Here is how they compare, using the shares reported by Laboratory News for the UK and by SThree for the full sample.
| Finding | UK (885 people) | All five countries (4,126) |
|---|---|---|
| Saw colleagues leave as AI changed their work | 15% | 16% |
| Saw colleagues leave over lost career progression | 14% | 14% |
| Saw colleagues leave over unsustainable workloads | 12% | 13% |
| Seniors now doing work juniors used to do | 29% | 32% |
| Employer struggled to replace specialists | 45% | n/a |
| AI adopted too fast to weigh the impact on roles | 37% | n/a |
That said, one caveat matters here. The answers describe what employees saw and felt. As Laboratory News notes, they do not prove AI directly caused each departure.
Will AI Replace Engineers? The Graduate Data Says Not Yet
Search interest in questions like “will AI replace engineers” keeps climbing. However, a separate UK report published two days later paints a calmer picture.
Prospects at Jisc released its “What do graduates do?” study on October 22, 2026. It found no evidence that AI is causing widespread graduate job displacement, as FE News reported.
Still, there are signs of possible substitution. The largest declines came among coders and software professionals, management consultants and graphic designers. Prospects says those drops may be partly linked to AI.
Overall, full-time employment for graduates fell from 67.3% to 65.8%. Charlie Ball of Prospects said opportunities are shaped “more by wider economic conditions and sector-specific pressures than by AI.”
AI Changing UK STEM Jobs Starts at Entry Level
Yet the quietest shift may matter most. In the UK, 29% said senior staff now take on work that junior colleagues used to do.
That matters for anyone hunting for entry level AI jobs in the UK. If AI handles the routine tasks, fewer starter roles exist to train the next generation.
As a result, the career ladder loses its bottom rungs. For now, today’s seniors cover the gap, but nobody is learning the job behind them.
The UK STEM Skills Gap Employers Now Face
Of course, losing people is one problem. Replacing them is another, and 45% of UK respondents said their organisation struggled to do it last year.
Rakesh Patel, UK managing director at SThree, warned that lasting skills gaps could follow. That happens when experienced staff leave faster than specialist knowledge can be rebuilt, Laboratory News reported.
According to Energy Live News, Patel said employers must use AI “where it genuinely belongs.” In other words, the tool should free experts to use their skills, not strip the interesting parts out of their jobs.
What AI Changing UK STEM Jobs Means for Workers
For STEM professionals, the message cuts both ways. Employers clearly fear losing specialists, so skilled people hold real bargaining power right now.
On the other hand, the work is changing whether you like it or not. Learning to steer AI tools, rather than compete with them, keeps you in the roles that remain.
If you are thinking about a move, AI can help there too. Our step-by-step guide shows how to use AI for job search without sending the same generic CV everywhere.
SThree says it will keep tracking these shifts across global STEM markets. For now, the lesson for UK employers is simple: introduce AI with people in mind, or watch them leave.

Frequently Asked Questions
How is AI changing UK STEM jobs?
AI is reshaping daily tasks and entry-level work. A YouGov survey for SThree found 15% of UK STEM staff saw colleagues leave after AI changed their jobs.
Are scientists and engineers leaving jobs because of AI?
Some are, according to the survey. Across five countries, one in six respondents saw colleagues quit after AI changed their work beyond recognition.
Will AI replace engineers?
Not on current evidence. Prospects found no widespread graduate job displacement in the UK, though coder and software roles showed the largest declines.
What is the SThree STEM Workforce Report 2026?
It is a YouGov survey of 4,126 STEM employees in the UK, Netherlands, Germany, US and Japan, run from July 10 to September 1, 2026.
Is AI taking graduate jobs in the UK?
Mostly no, says Prospects at Jisc. In its view, the economy and public sector funding shape graduate prospects more than AI does for now.
Why are UK employers struggling to replace STEM specialists?
Specialist skills are scarce, and 45% of UK respondents said replacements were hard to find. Meanwhile, AI is thinning the junior roles that once trained new specialists.
