Top Companies Hiring for Data & AI Jobs in London (Oct 2026)

You want to work in Data & AI in London, but you cannot tell which employers are actually hiring and which job boards are just recycling noise. Here is the honest picture from one dated snapshot, and what to do with it.

The numbers behind this snapshot#

On 14 October 2026, JobRise's live jobs feed showed 85 open Data & AI jobs in London. Of those, 62 were posted in the last 30 days, and 31 in the last 7 days. So more than a third of the market moved in the past week. That is a live feed count, not a market survey, and it will shift daily.

Nearly every role is permanent: 84 full-time listings and 1 contract. If you are hunting for day-rate work, London's Data & AI slice is thin right now. Adjust expectations before you burn weeks on contract-only searches.

Who is hiring, ranked by open roles#

These are the companies with the most open listings in the slice, names exactly as they appear on the postings. Some are recruiters or staffing firms, so the employer behind the role may be a client rather than the name you see.

• Anthropic: 13 open listings
• Intercom: 7
• Spotify: 6
• Zopa: 5
• Cohere: 4
• Lane Clark & Peacock: 3
• Infosys Consulting - Europe: 2
• Zoopla: 2
• Longshot Systems Ltd: 2
• Profile Software: 2

The top ten account for 46 of the 85 listings. The rest are spread thinly, which means many employers here are hiring one person, not building a team. Treat single-listing employers as quick, targeted applications rather than long-term relationship plays.

Titles tell you what each name wants, and nothing more. Zoopla lists a "Senior Data Engineer" and a "Data Engineering Manager", so its two roles sit on the engineering and management side. Longshot Systems Ltd lists a "Graduate Machine Learning Researcher", which is research-flavoured and entry-level. Infosys Consulting - Europe lists "Data Scientist - GenAI - Consultant", a client-facing consulting shape. Read the title, then map your CV to that shape.

London against the rest of the UK#

The slice shows 1,009 open listings in London across all categories, and 188 Data & AI listings across the whole United Kingdom. Put plainly: London holds 85 of the country's 188 Data & AI listings in this feed. The concentration is extreme. If you are outside London and can commute or relocate, your options roughly double.

For wider context on national hiring patterns, the JobRise Hiring Report: the UK tracks how demand moves across the country. Use it to judge whether a quiet week is a trend or noise before you change strategy.

What the titles say about seniority and pay#

Only 1 of the 85 listings looks entry-level on the title alone: "Graduate Machine Learning Researcher" at Longshot Systems Ltd. The rest read mid to senior, including "Senior Director, Analytics & Business Intelligence" at Nuvei, "Interim Lead AI Engineer" at Ki, and "Data Engineering Manager" at Zoopla. If you are early career, this snapshot is not kind to you. Broaden to adjacent titles and be ready to move fast on the rare graduate role.

Pay is rarely shown. Just 16 of 85 listings display a salary, and where they do, the numbers vary widely. As posted: "Data Analyst" at INSIGHT INTERNATIONAL Limited at £75K; "Data Analyst - Lorien Impellam" at Lorien Impellam at £58K; "Data Analyst" at Lorien at £70K; "Assurance - Financial Services - Forensic Data Analyst - Senior - London" at EY UK at £39K; "Data Analyst - Clapham Junction" at The Gym Group at £34K; "Data Analyst" at Comtecs Ltd at £80K-£85K. Same job title, wildly different bands. Salary ranges vary by employer and role, so verify current figures on the official listing or the employer's own site before you negotiate.

How to target each type of employer#

AI and research employers, the Anthropic and Cohere shape of listing, hire on evidence of depth. Show a portfolio, a paper, a strong open-source contribution, or a clear explanation of a model decision you made. Generic "passionate about AI" language reads as filler here.

Product companies such as Intercom, Spotify, Zoopla and Zopa care about shipping. Your CV should show what reached users, what it improved, and how you worked with engineers. Numbers you can defend beat adjectives every time.

Recruiters and staffing firms, including Lorien Impellam and Lane Clark & Peacock, are speed-driven. Give them a clean CV, a clear day rate or salary floor, and fast replies. They move quickly and drop candidates who go quiet.

Consultancies such as Infosys Consulting - Europe and Profile Software want client-ready communication. Practise explaining technical work to non-technical people. Your interview story should include a messy stakeholder, not just a clean dataset.

Referral and outreach scripts that work#

Cold outreach fails when it asks for a job in line one. Ask for information instead. Here is a message that gets replies:

"Hi Sam, I saw Zoopla is hiring a Senior Data Engineer. I have four years on Spark and dbt in retail data, and I am deciding whether to apply. Would you spare 10 minutes to tell me how the data team is structured? No ask beyond that. Thanks, Priya."

For a recruiter, be blunt and brief:

"Hi, applying for your Data Analyst role. Seven years' SQL and Power BI in financial services, immediately available, based in London. CV attached. Happy to talk today or tomorrow."

For a referral request, make it easy to say no and easy to forward:

"Hi Dan, hope you are well. I am applying for the Data Engineering Manager role at Zoopla and wondered if you would be comfortable passing my CV along. Completely fine if not. Two lines on me: led a team of six building a payments data platform, cut pipeline failures by around 40 percent. CV attached."

A worked example: rewriting a CV bullet#

Weak: "Responsible for data analysis and reporting for the marketing team."

Stronger: "Built a weekly attribution model in SQL and Python that replaced three manual reports, cut reporting time from two days to two hours, and was adopted by the marketing team of 12."

The rewrite names the tools, the change, and the effect. That is what a Data & AI hiring manager scans for in eight seconds.

Your 7-step plan#

1. Pick your lane. Data analyst, data engineer, ML engineer, or research. Titles in this snapshot do not overlap much, so a scattershot CV loses.
2. Work the top ten list in order, largest first. Anthropic and Intercom alone hold 20 of the 85 listings.
3. Tailor one CV per employer type: research, product, recruiter, consultancy. Four versions is enough.
4. Find two people at each target employer and send the outreach script above. Aim for information, not favours.
5. Check the free company insights tool before you apply, so you walk in knowing what the company does and where it is heading.
6. Apply within 48 hours of a listing going live. 31 of these 85 appeared in the last week, and early applicants get read first.
7. Track everything in a simple sheet: company, role, date applied, contact, next step. Review weekly and drop what is not working.

FAQ#

How current are these numbers?

They are a snapshot of JobRise's live jobs feed taken on 14 October 2026, counting open listings rather than surveying employers. Counts change daily, so re-check the feed before you plan around any figure.

Are these companies or recruiters?

Both. Some names, such as Lorien Impellam and Lane Clark & Peacock, are recruiters or staffing firms, so the hiring employer may be their client. Read each listing carefully to see who you would actually work for.

Is contract work an option in Data & AI in London?

Not much in this slice. The snapshot shows 84 full-time listings and 1 contract. If you want contract work, you will need to widen your search beyond this category or wait for the mix to change.

What salary should I expect for a data analyst role in London?

Where listings in this snapshot show pay, the posted figures range from £34K to £85K for analyst titles. That spread reflects very different seniority and sectors, so verify current ranges on the official listing before you negotiate.

Are there graduate or junior Data & AI roles in London?

Only 1 of the 85 listings in this snapshot looks entry-level on its title: "Graduate Machine Learning Researcher" at Longshot Systems Ltd. If you are early career, apply fast on those and widen your search to adjacent junior titles.
