9 Mothers

9 Mothers is a counter-drone defense company based in Austin, Texas. Its careers page frames the team as one that ships hardware on software tempo, covering AI perception, kinetic engagement, and the kill chain that connects them. The site positions the work as hard problems with real deployment and short iteration loops, where the people doing the work own the spec.

The page emphasizes four working principles. The work itself is the perk: autonomous perception, terminal engagement, and manufacturable hardware are designed and built in one room, with engineers owning systems rather than tickets. Short loops and real telemetry mean range time, range data, and range fixes drive iteration instead of roadmap decks. Operators are treated as users, with mass, setup time, and human factors as first-class specs. Finally, cost-per-shot, serviceability, and manufacturability are design constraints, reflecting a focus on affordable weapons for the U.S. and its allies.

The careers page lists seven open roles and invites candidates to request a brief. Hiring spans audio ML, DSP, systems, and software, suggesting demand for both signal-processing depth and full-system engineering. The content is aimed at engineers who have shipped hardware inside slow programs and want to move in months rather than years.

Applicants should review the open roles and the stated principles before requesting a brief, then assess fit with the Austin location and the hands-on, deployment-focused culture. The
