Technical search

The machine learning role you've had open since spring.

Hensois finds AI, ML and data engineers for European product companies between 20 and 200 people — the size where the vacancy hurts every week and nobody internally is dedicated to filling it.

The focus

One field, done properly

Most agencies will take any brief that lands. That's why they send you six CVs that don't read the job description.

Hensois works one field only: machine learning, applied AI and data engineering. ML engineers, data engineers, MLOps and platform, applied scientists, analytics engineers.

Narrow enough to actually judge whether someone's production experience is real, and to keep a live network in it rather than starting each search from a blank search bar.

Where we work

  • Germany, Netherlands, Nordics

  • Remote-first teams hiring anywhere in the EU
How it runs

Three steps, no retainer

STEP 01

A real conversation

Thirty minutes on what the role actually needs, versus what the job description says. Those two things are rarely the same, and the gap is usually why the role is still open.

STEP 02

A short list, not a long one

Three to five people who have done the work, have agreed in writing to be introduced to you, and are genuinely available. No CV spraying.

STEP 03

You hire, then you pay

Nothing is invoiced until someone signs and starts. If it doesn't work out in the first 90 days, we replace them or refund you.

Terms

Stated up front, so you don't have to ask

18%

Of first-year gross salary. Contingency — invoiced 30 days after the start date, never before.

90 days

Guarantee period. If they leave or it isn't working, a free replacement or a pro-rata refund. Your choice.

€0

Up front. No retainer, no exclusivity demanded, no charge for a search that doesn't produce a hire.

Straight talk

What we turn down

Taking on a search that can't close wastes six weeks of everyone's time. So some briefs get declined:

  • Roles open more than six months where no offer has ever been made
  • Searches already running with four other agencies
  • Salary bands well below the market for that seniority
  • Full-time onsite in an expensive city with no relocation support

If you're a candidate

You'll never be sent anywhere without your explicit written consent, and you'll always know which company before your name goes near it.

No CV blasting, no keeping you on a list forever. Ask to be removed and your details are deleted the same day.

Get in touch

Tell me the role

Send the job description, or just describe the problem — what the team is trying to build and who's missing. I'll tell you honestly whether it's fillable, and roughly how long it should take.
