Build where the map ends.
We hire people who would rather build the thing than describe it. You join the parent company, own a real problem in one of four divisions and borrow the whole bench whenever you need it.

Why we’re here
The most important work of the next decade will be done by small teams who are allowed to build at every scale.
Clexerl is built so that a team of five can ship like a team of fifty: one shared engineering bench, one balance sheet and one distribution engine behind every venture. You spend your time on the problem, not on rebuilding the company around it.
How we work
Six habits we hire for, promote on and hold each other to.
Build the thing
A working prototype settles more arguments than a slide. We demo early, we demo often and we let the thing speak for itself.
Every scale, same rigour
A rounding error in a spreadsheet and a car crossing a city get the same care. Small problems are where big ones hide.
One bench
Engineers, capital and distribution are shared across ventures. You move to where the problem is, without a transfer form.
Say the true thing
We disagree in writing, in the open and early. Then we commit. Nobody has to guess what anybody thinks.
Own the outcome
You own a problem end to end, not a ticket. If something you shipped breaks, you hear about it first and you fix it.
Measure twice
We move fast and we measure. Safety cases, evals and post-mortems are part of the work, not a tax on it.
Life at Clexerl
Studios in Columbia, New York, San Francisco and London. Whiteboards everywhere.

the plan, v14“I shipped to the vehicle in my second week. Nobody asked me to write a design doc first. They asked me to show them it worked.”
Perception Engineer, Autonomy “The memory work I do ends up in Clexerl Go a month later. You can see your research change how a few thousand teams plan their week.”
Research Engineer, Frontier AI “Disagreeing in writing felt strange for a month. Now I can’t imagine going back to finding out what people think in the hallway.”

- Equity in Clexerl, plus a stake in the venture you help build when it spins out.
- 22 weeks parental leave
- Fully paid, for every parent, however your family arrives.
- Rest that sticks
- Flexible time off with a four-week minimum we actually check on, plus a company-wide week in December.
- Learning and compute
- A yearly budget for courses, conferences and books, and compute credits for side projects.
- 401(k) with a 4% match
- Matched from your first paycheque and vested immediately.
- Relocation, handled
- Moving costs, temporary housing and visa support for every hub.
- Lunch on the bench

Questions, answered
Do I need a background in AI or robotics?
For research roles, usually yes. For most engineering, product and operations roles, no. We care more about what you have built and how fast you learn than about the field you learned it in.
Can I apply to more than one role?
Yes, up to three at a time. Recruiters see every application, so we will route you to the best fit even if it is a role you did not pick.
Do you sponsor visas?
Yes. We sponsor and transfer visas for every hub and cover the legal costs, and we have done it for most nationalities.
How does remote work?
Roles marked remote-friendly can be done from anywhere in the US, with a week together in a studio each quarter. Hybrid roles are in the studio three days a week.
What does “work across divisions” mean in practice?
You join a team in one division, but the engineering bench is shared. People regularly spend a quarter on another division’s problem when it needs them, and come back with something useful.
Are the salary ranges real?
They are the base salary ranges we would pay in the US for each role. Final offers depend on level and location, and every offer also includes equity.
