CompanyCareersRequest a brief

[ CAREERS · 9 MOTHERS ]

We ship hardware on software tempo — AI perception, kinetic engagement, and the kill chain that closes them. Hard problems, real deployment, short iteration loops, and the people doing the work own the spec.

If you've ever shipped hardware inside a slow program of record and thought we should be doing this in months, not years — this is the team for you.

Autonomous perception, terminal engagement, manufacturable hardware — designed and built in one room. You'll own a system, not a Jira ticket.

Range time, range data, range fixes. We instrument what we build and we iterate on what the data tells us — not on what the roadmap deck promised six months ago.

Mass, setup time, and human factors are first-class specs. The people carrying it are in the loop from week one — not at acceptance testing.

Cost-per-shot, serviceability, and manufacturability are design constraints. We're building weapons the U.S. and its allies can afford to use at scale.

We're hiring across audio ML, DSP, systems, and software. If you don't see the exact role but you'd be the right person, send us a note anyway.
