Careers

Senior practitioners,
building Witness.

Witness is the consulting practice and the AI agent. Senior-only, principal-reviewed, and built to hold up in court. If that is the work you want to do, the door is open.

How we staff

Three principles, no exceptions.

Senior-only bench

No tier-1 ticket factory, no offshore phones, no junior staff fronting senior work. Every practitioner has earned the credentials and the case-hours that make the work defensible. We staff for that, not for billable-hour multipliers.

Court-admissible standard

Methodology is built around FRE 901, FRCP 26, chain of custody, and Daubert qualification. The work has to hold up in deposition before it ever holds up on a Slack message.

AI-augmented, principal-reviewed

Witness, our AI agent, scales the procedural work that used to consume senior-analyst hours. Practitioners review and attest every output. The medical-imaging-AI pattern: AI does the first read, the credentialed practitioner does the final read.

Open tracks

Roles we are looking to fill.

We hire selectively, not opportunistically. If your background fits the practice but not a listed role, send a note anyway and make the case for the role you would create.
