Motor Drive Firmware Engineer

*Company Overview
*

Allen Control Systems (ACS) is a cutting-edge defense startup founded by two former Navy electrical engineers with a proven track record in robotics and software. We are developing an autonomous gun turret using advanced computer vision and control systems to precisely detect, track, and neutralize enemy drones.

With an engineering-first culture, ACS values technical excellence and innovation. Backed by our founders’ successful exits from two previous ventures acquired for a combined $180M in 2022, we are committed to ensuring that the groundbreaking technologies we develop will have a real-world impact.

About The Role
We are looking for a Motor Drive Firmware Engineer with deep expertise in embedded systems and real-time control for electromechanical systems. You will design and implement high-performance motor control firmware critical to the precision and reliability of our autonomous platforms, working closely with electrical, mechanical, and systems teams to ensure seamless integration across hardware and software.

We’re hiring across multiple experience levels, including:

• Associate Engineer
• Engineer
• Senior Engineer
• Staff Engineer
• Senior Staff Engineer

Your title and level will be determined based on your experience, skills, and the scope of responsibility appropriate for the role.

What You’ll Do

• Design and implement embedded firmware in C/C++ for real-time motor control, including high-frequency control loops, deterministic system behavior, and control algorithms (PID, FOC) for BLDC, PMSM, or similar motor systems.
• Work closely with electrical engineers to bring up motor control boards, including debugging power stages, gate drivers, and sensor feedback systems.
• Use lab equipment including oscilloscopes, logic analyzers, and power analyzers to validate performance and troubleshoot control, timing, and signal integrity issues.
• Optimize firmware for latency, efficiency, and reliability in hardware-constrained environments; conduct lab and field testing to validate motor performance under real-world operating conditions.

What You’ll Need
3+ years of experience in embedded firmware development with a focus on motor control systems.
Strong experience with real-time control loops and BLDC/PMSM motors, motor drivers, and power electronics.
Proficiency in C/C++ for embedded systems and experience with microcontrollers such as STM32, TI C2000, or similar.
Strong debugging skills using hardware lab tools including oscilloscopes, logic analyzers, and power analyzers.

You’ll Stand Out

• Experience with Field-Oriented Control (FOC) or advanced motor control techniques.
• RTOS or bare-metal real-time firmware experience.
• Experience integrating firmware with mechanical systems and actuators.
• Familiarity with high-reliability or defense systems.

What We Offer

• Competitive salary
• ACS Equity Package
• Health, Dental, Vision Insurance
• Paid Time Off
