About Wild West Systems

Born in America. Built for the Future Warfighter.

Robotics are reshaping the battlefield, and yesterday’s weapon systems are outdated, expensive, and built for the past.

Wild West Systems is building the universal weapons layer for robotics: precision weapon systems designed to make autonomous platforms more capable, more lethal, and fully reusable. We’ve built a team of leading engineers from companies including Tesla, Apple (Special Projects Group), SpaceX, and more to rethink what these platforms are capable of.

This is the Wild West.

The Role

As a Firmware Engineer, you’ll develop the embedded systems that connect software to real hardware, working across electronics, sensors, actuators, motor control, and autonomous systems. This is where firmware meets steel.

• Develop embedded systems on STM32 microcontrollers.
• Develop low-level drivers, peripherals, communication protocols (UART, SPI, I2C, CAN), and real-time systems.
• Work at the intersection of electronics, sensors, actuators, motor control, and embedded software.

Requirements

Required Qualifications

• Bachelor’s degree in Computer Science, Software Engineering, or a related technical field (or equivalent experience).
• 3+ years of professional firmware engineering experience.
• Solid mechatronics background.
• Experience developing production-quality firmware in Rust.
• Experience troubleshooting hardware/software interactions.
• ITAR eligibility as outlined above.

Preferred Qualifications

• Experience in defense, aerospace, robotics, or autonomy.
• Familiarity with drone/UAV systems, real-time operating systems, or embedded development.
• Experience at a high-growth startup or technology company with strong engineering practices.
• Experience using the Embassy asynchronous embedded framework.
• Experience taking systems from prototype through deployment.

Why Wild West

• Build the whole thing. Own your work from first principles through design, prototype, test, iteration, and production. What you build will leave the screen and enter the real world.
• Build where the hardware gets built. Engineering, fabrication, manufacturing, and testing happen under one roof, so ideas move fast.
• Make an impact from day one. Your decisions will shape the product, the roadmap, and the company itself.
• Move at mission speed. Work with urgency, solve hard problems, and turn ambitious ideas into field-ready systems.
• Share in what you build. Every employee has the opportunity to own stock options and participate in the company’s success.
• Work with exceptional people. Join a team defined by high standards, low ego, direct communication, and relentless execution.
