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

You want a data or AI job in Paris and you are tired of guessing who is actually hiring, so here is the picture as of 14 October 2026: JobRise's live feed showed 25 open Data & AI jobs in Paris, and 22 of them went up in the last 30 days. Eight appeared in the last week alone.

That is a snapshot of open listings, not a market survey. Use it as a map for this week's applications.

Who is hiring, ranked by open listings#

Counts come from company names and listing titles on JobRise, 14 October 2026. Some names are recruiters or staffing firms, so one listing can sit in front of several end clients.

1. Datadog, 11 listings. Nearly half the slice. Target this one first.
2. Fifty-Five, 5 listings. Consultant titles across digital analytics and data consulting.
3. Ubisoft, 3 listings. Titles not itemised in the snapshot beyond the count.
4. Profile Software, 1 listing: "AI & Machine Learning Engineer".
5. Allucent, 1 listing: "Sr. Clinical Data Manager (Europe)".
6. Quandela, 1 listing: "Quantum Information Scientist - Quantum Dot Modelling".
7. Celonis, 1 listing: "Senior/ Lead AI Deployment Engineer - Supply Chain".
8. Anthropic, 1 listing.
9. Infosys Consulting - Europe, 1 listing.

Nine companies, 25 roles. The shape is brutal: two names hold 16 of the 25 openings, which means one focused week of research on Datadog and Fifty-Five beats a scattershot month of generic applications. Concentration is your friend.

What the titles tell you#

Read the titles word by word, because they set the bar. "Senior" and "Lead" show up in the Fifty-Five, Celonis and Allucent roles, and the Quandela post wants a scientist with real quantum dot modelling depth. The Profile Software seat is the closest thing to generalist AI engineering here.

One blunt number matters more than the rest: 0 of these 25 listings look entry-level. No intern, graduate, junior or trainee titles in the slice at all. Early career? Then widen the net.

No listing in this slice shows a salary. Do not guess what these roles pay, ask in the first call, and check the official French sources on gross versus net because candidates confuse the two constantly.

Paris against the country#

Paris holds 25 of the 45 Data & AI listings open across all of France on the same date, so more than half the national market sits in one city. The city has 267 open listings across every category, and Data & AI is under a tenth of that. Small slice. Loud signal.

For country-level movement and how the rest of France is hiring, the JobRise Hiring Report: France tracks the wider picture, and it is worth a look before you blame your CV for a national slowdown.

How to target each type of employer#

Large product company with many openings, like Datadog. Apply to more than one posting but tailor each one, find the team lead on LinkedIn, name the exact role title, and keep it short. Volume helps because they clearly hire across several teams.

Agency or consulting firm, like Fifty-Five or Infosys Consulting - Europe. They sell your time to clients so they care about billable skills and whether you can hold a room, and speaking French matters more here than in a product company. Name the sectors you have worked in.

Deep-tech and research-heavy shop, like Quandela. Your publication record and technical depth carry the application, and a generic data scientist CV dies here. Lead with the exact method they name in the posting.

Recruiter or staffing firm, like Profile Software or Allucent. Get into their database and stay in touch, because one conversation can turn into several client submissions and that is why these single listings are worth more than they look.

Corporate with a niche vertical, like Celonis in supply chain or Allucent in clinical data. Domain knowledge is your way in, so if you have never touched their field, say what you have shipped in an adjacent one and be concrete.

Referral and outreach scripts#

Ask for a referral with a message a person can answer in 30 seconds.

"Hi Marie, I saw the Senior Data Consultant (H/F) role at Fifty-Five and I think my 4 years of digital analytics work in retail fits. Would you be open to referring me? Happy to send my CV in one line if that helps. Either way, thanks."

Cold message to a hiring manager, after you have applied.

"Hello, I applied for the AI & Machine Learning Engineer role at Profile Software this morning. My background is 3 years building ML services in Python, most recently a demand forecasting model used daily by ops. I know you are busy, so one question: is there anything about the profile you would want to see strengthened? Thank you for your time."

Message to a recruiter with a staffing firm.

"Hi, I noticed your Sr. Clinical Data Manager (Europe) opening. I have 6 years in clinical data management with EDC systems and CDISC standards, and I am based near Paris. Are you handling other data roles in the area? I would like to be considered for anything close."

Keep these under 80 words. Send Tuesday to Thursday morning. Follow up once after a week, then let it go.

A 7-step plan#

1. List the nine companies above and rank them by how your skills match the titles, not by brand name.
2. Read every posting word by word and pull out the exact tools and methods they name.
3. Rewrite the top third of your CV so those words appear where they belong, only if you actually have them.
4. Use the free company insights tool to check each company before you write anything.
5. Find one person at each target company and send the referral script, starting with Datadog and Fifty-Five.
6. Apply to 3 roles a day, no more, and log each one with the date, title and who you contacted.
7. Review the log every Friday. If a company has not replied in 10 days, move on and spend the time on a new target.

The plan works because it is small enough to finish. Candidates who fail usually fail at step 6, sending 40 applications and tracking none of them.

FAQ#

Are these companies still hiring in Paris?

The counts are a snapshot of JobRise's live feed on 14 October 2026 and they change daily. Datadog had 11 open listings and Fifty-Five had 5 on that date, but any of these can close within a week. Recheck the feed before you invest an evening in an application.

Should I apply if I do not meet every requirement?

Apply when you meet the core tooling named in the title and the first line of the posting. With 0 entry-level listings in this slice, the bar is set for experienced hires, so a junior profile needs something exceptional to stand out. Do not stretch into a quantum dot modelling role without the physics behind you.

Why are recruiters listed alongside real employers?

Some names on the listings are staffing firms or agencies rather than the end employer. That is normal and often useful, since one recruiter can submit you to several clients. Just ask clearly which company the role is for before you invest time.

Is French required for these roles?

It varies by employer and by team. The Fifty-Five titles carry the (H/F) marker common on French postings, and consulting work with French clients usually needs solid French. Product companies with international teams often run in English, so ask early rather than assuming.

What salary should I expect for these roles?

No listing in this slice shows a salary, so there is nothing to quote from the data. Reported ranges for senior data and AI roles in Paris vary widely by company type and seniority. Ask in the first call and verify figures against the current official French sources before you negotiate.
