Location: Onsite — Austin, TX

Employment Type: Direct Hire, Full‑Time

Job Title: Staff Embedded Engineer (BSP)

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 Lead Embedded Engineer (BSP) to own the Board Support Package and embedded platform underlying our counter-sUAS systems. The Lead Embedded Engineer is responsible for board bring-up, Linux platform development, device driver engineering, and the operating system framework upon which our perception, controls, and autonomy software operate. This is a senior individual contributor position.

Essential Duties

• Lead end-to-end bring-up of new board revisions, including bootloader, kernel, device tree, and peripheral driver development.

• Own the Linux platform image that ships on production systems, including kernel configuration, patching, and long-term maintenance.

• Design and maintain the operating system framework supporting application software, including process supervision, inter-process communication, logging, configuration management, and update and rollback infrastructure.

• Develop and maintain device drivers for cameras, inertial measurement units, motor controllers, and custom hardware peripherals.

• Implement, optimize, and maintain EtherCAT communication stacks to ensure low-latency, deterministic control of motor controllers and robotic actuators.

• Establish and operate the build, signing, and provisioning pipeline for production deployment.

• Diagnose and resolve complex issues spanning the hardware, kernel, and user space boundary.

• Define standards and best practices for embedded software development, testing, and deployment.

Requirements

• 6+ years of professional experience developing and shipping production embedded Linux systems.

• Expert proficiency in C and Linux kernel development, including driver development, device tree, and kernel internals.

• Demonstrated experience leading full board bring-up from schematic review through production-ready peripheral drivers.

• Strong systems programming experience in Rust or C++, with exposure to real-time industrial networking protocols (e.g., EtherCAT, CAN bus).

• U.S. citizenship and ability to pass a background check.

Preferred Qualifications

• Experience with NVIDIA Jetson platforms (Orin, JetPack).

• Yocto Project and meta-layer development experience.

• Prior experience establishing BSP practices at an early-stage or small-team hardware company.

• Active security clearance, or eligibility to obtain one.

• Prior experience in defense or other safety-critical applications.

• A passion for building robots or engineering projects as a hobby.

Benefits

• Meaningful Early Equity: You aren't just an employee; you are a foundational owner. Your contributions directly drive the value of your stake in the company.

• Direct Roadmap Influence: Forget the bureaucracy of big defense. You will have a seat at the table, directly shaping our product and technology trajectory from day one.

• 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.

• The Builder's Playground: Work in a brand-new lab fully optimized for rapid prototyping, equipped with NVIDIA Jetsons, high-end scopes, and 3-D printers.

• 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. Take the time you need to stay sharp and recharge.

• Zero Red Tape: You report to the founders. You have the autonomy to make technical decisions that would take months of committee approval at a larger firm.

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

• Relocation Assistance: We want the best talent in the room. If you aren't in Austin yet, we’ll help you get here, to make your transition to the Silicon Hills seamless.
