About the role

  • This is a senior individual contributor position focused on control theory.

Responsibilities

  • We don't build for "what if." We build systems the Department of War actively needs to counter immediate, real-world threats.
  • 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.
  • Design, implement, and tune the control stack for EDDA's motion system, including actuators and gimbaled subsystems.
  • Develop and maintain high-bandwidth control loops, including PID, feedforward, and model-predictive control as appropriate to the application.
  • Develop and maintain state estimation pipelines that fuse inertial measurement unit data, encoder feedback, and perception output into a consistent target track.
  • Characterize and model mechanical nonlinearities - including backlash, cogging, stiction, inertia, and structural modes - and develop compensation strategies.
  • Your contributions directly drive the value of your stake in the company.
  • Mission-Critical Work: We don't build for "what if." We build systems the Department of War actively needs to counter immediate, real-world threats.

Requirements

  • 6+ years of professional experience in production controls engineering within motion systems, robotics, aerospace, or comparable real-time domains.
  • Proficiency in Rust, C, or C++ for real-time code, and Python for analysis and tooling.
  • Demonstrated track record of bringing a complex physical system to production-grade performance.
  • U.S. citizenship and ability to pass a background check.
  • You have the autonomy to make technical decisions that would take months of committee approval at a larger firm.

Nice to have

  • Experience with gimbal, turret, or pointing-system design.
  • System identification and model-based control experience.
  • Hands-on experience with motor drivers, CAN bus, and RTOS targets.
  • Experience with ROS 2 or DDS middleware in production.
  • Active security clearance, or eligibility to obtain one.
  • Prior defense startup experience
  • you are a foundational owner.
  • Direct Roadmap Influence: Forget the bureaucracy of big defense.

Skills

  • Continuously improve slew rate, settling time, and pointing accuracy as the hardware platform evolves.

Compensation

  • Characterize and model mechanical nonlinearities — including backlash, cogging, stiction, inertia, and structural modes — and develop compensation strategies.

Benefits

  • Meaningful Early Equity: You aren't just an employee; you are a foundational owner.
  • 100% Employer-Paid Premiums: We cover 100% of your medical, dental, and vision insurance premiums and cover 50% of healthcare premiums for your dependents.
  • Unlimited PTO: We value results, not clock-watching.

Company info

  • Join an onsite team in Austin, TX, where we prioritize high-bandwidth collaboration and rapid field-testing.
