Job Description
Location: Onsite — Austin, TX
Employment Type: Full‑Time
Job Title: Lead Robotics Engineer
Company Overview
9 Mothers Defense develops AI-enabled systems to counter unmanned aerial threats. Our first product, EDDA, is an autonomous counter-sUAS point-defense platform designed to detect, track, and neutralize Group 1 drone threats. The company is headquartered in Austin, Texas.
Position Summary
9 Mothers is seeking a Robotics Lead to own the control systems and motion engineering for our counter-sUAS platform. The Robotics Lead is responsible for the design, implementation, and tuning of the high-bandwidth control loops and state estimation that enable EDDA to track and engage small, fast-moving aerial targets with precision. This is a senior individual contributor position focused on control theory.
