Gap between 25th and 75th percentile for senior ML Engineer in London

Most candidates who don't negotiate land at the 25th percentile. Strong negotiation moves you toward the 75th — a difference of £62K per year.

How to negotiate a Machine Learning Engineer offer in London

The difference between the 25th and 75th percentile is £62K/year — and it comes down to this conversation.

0101

Anchor above the median

Open at £201K — the 75th percentile. This gives you room to "meet in the middle" at or above the median. Never give a range; ranges get taken at the low end.

0202

Use competing offers as leverage

A competing offer — even from a less preferred employer — is the single most powerful negotiating tool in London. Get at least one before negotiating.

0303

Negotiate total comp, not just base

Base salary is often the hardest component to move. Signing bonus and equity are frequently more flexible. In London, a £21K signing bonus has the same year-1 value.

0404

Never accept on the call

Ask for the offer in writing and follow up in 24–48 hours. This creates space to counter without pressure. No legitimate employer rescinds an offer because a candidate asked for review time.
