Can Britain Pay Its Own Engineers Enough to Keep Them?

On 25 September, Google announced Polaris, a new DeepMind team. This week, one of the people it hired turned that announcement into a number, and the number is the part that travels.

The scientist is Tamay Besiroglu. He quote-tweeted Google's own post with a pitch that reads less like a job advert than a tide table. No degree required, he wrote. All that matters is that you are smart and can solve hard problems. Total compensation is $550,000 to $1,100,000. The job advert says something else, he added. Ignore that.

The post he quoted was Google's, from 25 September: an invitation to join Polaris, a new DeepMind team designing the evaluation frameworks for AI coding agents. Besiroglu is the kind of founder the largest labs buy. In September, Google completed a deal reported at more than $1.5bn to move him and a dozen engineers from Mechanize, the startup he co-founded, into DeepMind. The industry calls it the acqui-hire: buy the team, license the software, leave the shell.

A number that behaves like a force

Set it against home. Market guides put a senior AI engineer in London at roughly £90,000 to £145,000, and a principal at £145,000 to £200,000. Those are estimates, not official data. Heidrick and Struggles surveyed 318 executives across the US, UK and Europe: the senior AI leaders among them earn about $583,000 in total in Britain against roughly $878,000 in America, a gap of nearly $300,000.

US senior AI leader$878,000

UK senior AI leader$583,000

The advertised band is several times a UK salary. It is not a wage; it is a force. And money is only part of it. It is also the compute, the data, the colleagues and the permission to publish. The number is the part you can see, and the part that pulls.

The government is not asleep

This is not happening unseen. Britain has a £500m Sovereign AI fund that offers visa decisions within a working day, and a £1.1bn AI hardware plan with money for doctoral training. In August it widened the Global Talent visa so more than a hundred companies can sponsor researchers. The AI minister, Kanishka Narayan, has said visa reform is the key to keeping technology companies in Britain.

But the machinery is moving

The complication is that the machinery changed. In July the Department for Science, Innovation and Technology was abolished and its duties split across government, with Narayan given a cabinet seat instead. A London immigration lawyer, Charles Avens, called the ambition not grounded in reality. And most of these measures bring talent in. A visa that attracts a researcher is not a reason for one to stay.

Where that leaves the rest of us

I have built AI systems for British clients, and I would rather keep building them here. I saw the number and felt the pull before I felt any principle. But a country cannot grow its own technology by exporting the people who make it. If the brightest leave, the firms that would have employed them leave too, and what stays is a reputation for training other countries' workforces. Education sits upstream of this; I have written about it elsewhere.

The honest counterpoint

A real case exists that this is circulation, not a drain, and that talent following the compute is how expertise comes home. Many stay. The Heidrick survey measures senior executives, not the median engineer, and pay, not loyalty. What would change my mind is a British employer matching two thirds of the American band, with retention numbers to prove it worked.

The choice

When I read that post, the offer was not asking my country's permission. It was asking for its engineers. The question is not whether a government can match the number. It is whether it can offer anything a bigger number cannot buy. On the evidence, we are being outbid.

Readout: what is confirmed, what is reported, and what is not

• The hiring post is the poster's own claim, shown in full: $550,000 to $1,100,000, no degree required, and the admission that the job advert says something else. Google's own post named no figure.
• Confirmed (Business Insider, 11 September 2026): Google completed a talent-and-licensing deal for Mechanize reported at more than $1.5bn; Besiroglu and more than a dozen engineers moved to DeepMind; Mechanize was founded in 2025 after a $9.1m seed.
• Reported (Heidrick & Struggles 2025 Data, Analytics and AI Officers Compensation Survey, via AI Magazine, 2 August 2026): senior AI leaders earn about $583,000 in the UK against about $878,000 in the US, a gap of about $295,000. The survey covered 318 executives, not engineers.
• Confirmed (GOV.UK, 16 April and 8 June 2026; Wired-Gov/Home Office, 6 August 2026): the Sovereign AI fund, the AI Hardware Plan and the Global Talent visa expansion, with the figures as stated.
• Reported (City AM, 27 July 2026; BBC News, 21 July 2026): the DSIT abolition, Narayan's cabinet seat, and the lawyer's criticism.
• Argument, not fact: the reading that a wage this size behaves as a force, and that attraction is not retention, is mine, not a finding in any source.
• What would change my mind: a British employer matching two thirds of the American band, with retention numbers to show it worked.
