Questions about these roles
How many lead and principal Machine Learning jobs in the UK are there right now?
We are tracking 178 live vacancies across 67 employers. The crawler revisits employer careers pages continuously and roles disappear from this page as soon as they come down, so the count reflects what is genuinely open today.
What do lead and principal Machine Learning jobs in the UK pay?
The median advertised ceiling is £150,000, based on the 10 of these roles that publish a figure. The middle half of the market runs from £123,000 to £150,000. Contract day rates are annualised so they compare against permanent salaries.
Can these roles be done remotely?
51% are advertised as fully remote and 29% as hybrid. The rest are on-site or do not say — where an employer is silent we leave it blank rather than guessing.
Are these contract or permanent roles?
Every role here that states a basis is permanent. Contract vacancies are listed separately.
Which employers are hiring?
The most active right now are Monzo, Pubmatic, Realtechnicalsolutions, Dolly and Taskrabbit. Every vacancy links straight to that employer's own careers page — we are an aggregator, not the hiring company, and there is no middleman between you and the application.
What other skills do these roles ask for?
Most often Python, Kubernetes, Java, C++ and React. That is counted from the live adverts on this page rather than a fixed list, so it tracks what employers are asking for this month.
How much does a Machine Learning developer earn in the UK?
£150,000 is the middle of what is advertised here, which is 173% above the £55,000 median across UK IT as a whole. Read it as the ceiling an employer is advertising towards rather than an offer: 168 of these adverts name no figure at all, and those are the ones where asking early is worth most.
Can you work from home as a Machine Learning developer in the UK?
141 of the 178 live adverts here offer home working in some form — 90 fully remote and 51 hybrid. Fully remote means the advert states no office requirement; hybrid means it names a split.
Are there entry-level or graduate Machine Learning developer jobs in the UK?
Not right now — every live advert here signals mid-level experience or above. Graduate intakes are seasonal, so this is worth checking again rather than reading as a permanent state of the market.
What job titles are used for this role?
Employers on this page advertise it as Software Architect, Engineering Manager, Staff Machine Learning Engineer, Technical Program Manager and Data Solutions Architect. Searching one wording and not another is the most common way people miss vacancies, which is why this page groups them.
