We hire for the long run. Permanent roles are CLT or contractor, fully remote. The talent pool holds specialties we bring in per project.
THE TEAM
A small, stable team: the same people, year after year. Over time each person learns how the others think and how they fail — and no process replaces that.
Our communication is constant and direct: real context, no detours, no meeting to fill a calendar. And when silence comes, it bothers no one.
Nobody carries a hard problem alone: what blocks one becomes the group's business. There is no internal competition and no fight for space. This is not a stopover — it is where a career is built, and whoever fits notices quickly.
HOW WE WORK
Our greatest asset is our name. The deadline is set before we start and it holds. When the work needs more time, the delay is ours: we would rather pay a penalty than deliver something that has not gone through the full quality review.
Between taking the loss and harming whoever trusted our company, we take the loss.
MISSION, VISION AND VALUES
This is not lobby decoration. It is the criteria we use to accept a project, to hire and to turn work down — including when turning it down costs money.
Mission
Protect systems that cannot fail.
Vision
The place where hard work is done calmly.
Values
Consistency. Rigor. Autonomy. Permanence.
BENEFITS
Flexible hours
You organise your own day. What we track is delivery by the deadline you committed to, not the hour you sit down.
Team support
Nobody stays stuck on a problem alone. Asking for help costs nothing here and goes into nobody's review.
Continuous learning
Courses and certifications paid by the company when the content applies to what you do.
Project bonus
A share in the results of the projects you lead that meet the agreed targets.
