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

We are seeking an experienced Senior Robotics Engineer to join a small, fast‑moving team. You will design and implement the physical control systems — the “body” — of our interceptor platforms. This role is critical, as the accuracy of our control theory dictates the success of every high‑speed maneuver in combat. You should be comfortable writing code and working with robotic components (actuators, controllers, compute, sensors, etc.).

Essential Duties

• Design and implement high‑bandwidth control loops and advanced control algorithms (e.g., PID control) to ensure vehicle stability and enable high‑speed, precise maneuvers under dynamic load.

• Write high‑quality, efficient code (primarily Rust, C, or C++) to control and manage actuators, motor drivers (via CAN bus), and sensors on a real‑time operating system (RTOS).

• Integrate and fuse sensor data from cameras and IMUs (using methods such as EKF/UKF) on embedded systems (e.g., NVIDIA Jetson) to achieve reliable, real‑time state estimation.
