We hire researchers — people who have found what the industry missed, or shipped a system that could not afford to fail. Write us a letter. Not a résumé.
A research organization, not a product factory

Time to research
Thirty percent of the week belongs to your own inquiry. No project, no approval, no clock.
A laboratory that is yours
Hardware, sandboxes, and budget for real lab work — not a laptop and a Jira board.
A room that is quiet
Real offices, real doors, no open-plan theatre. Deep work is the whole of the job.
Disclosures, credited
Every coordinated disclosure carries your name. The work is public and yours.
Zero-meeting Wednesdays
One day a week where the only meeting is with your work.
The record, in writing
Equity and compensation written down, verified, and kept on the record.
12.1Open research threads
Where you might sit.
12.2The process
Four steps, no theatre.
A letter
Write to us, not a résumé. Tell us what you have found in the dark and what you want to build next.
A problem
We send one problem from the research queue. Solve it on your own time, on paper, your way.
The deep dive
Half a day with the team. We push on your reasoning the way we push on our own findings.
Compose
An offer, a quiet week to decide, and a first research thread that matters from day one.
The letter is the interview
Tell us what you have found in the dark — and what you want to build next.
We read every letter personally. If it holds, we write back within a week.
