Test Integration Engineer

Company Overview
ACS (Allen Control Systems) is a defense technology company building precision robotic systems for the United States and its allies. Founded by two former U.S. Navy electrical engineers with deep experience in robotics and software, ACS brings together AI, computer vision, precision motion, and advanced hardware to solve complex defense challenges across land, air, and maritime environments.

Our flagship product, Bullfrog, is an autonomous precision weapon system that transforms existing weapons into highly accurate counter-drone systems — giving warfighters a scalable, cost-effective response to one of the fastest-growing threats on the modern battlefield. Bullfrog is deployed with U.S. forces, and ACS works with organizations throughout the U.S. military and national security community.

Following a $200 million Series B at a $2.2 billion valuation, ACS is rapidly expanding manufacturing, accelerating Bullfrog deployments, and developing the next generation of autonomous battlefield systems. This is an opportunity to join a proven, fast-moving team and help scale technology with direct, real-world impact on national security.

ACS is headquartered in Austin, Texas, with additional operations in Alexandria, Virginia; Mountain View, California; and Huntsville, Alabama. For more information, visit allencontrolsystems.com.

About The Role: 

We are looking for a Test Integration Engineer to join our team, focusing on system integration, bring-up, debugging, and validation of our next-generation autonomous weapon platforms. This role is highly hands-on and involves working across electrical, mechanical, and software systems to diagnose issues, improve reliability, and ensure systems perform in real-world conditions.  

What You'll Do: 

• Integrate electrical subsystems including motor drivers, sensors, cameras, networking and power systems.

• Perform system bring-up, debugging and validation during prototype and production phases.

• Debug and integrate systems spanning Linux-based platforms and STM32 firmware.

• Use oscilloscopes, logic analyzers, spectrum analyzers, and other lab equipment to diagnose power, signal integrity, timing and communication issues.

• Develop and execute test procedures for electrical, communication and system level validation.

• Support field testing and help root-cause failures observed during operation

• Collaborate with hardware and software engineers to improve design robustness and testability.

• Build and maintain test fixtures, harnesses, and automation tools where appropriate 

• Assist in validating new hardware revisions and verifying design changes.  

What You'll Need: 

• Bachelor’s or Master’s degree in Electrical Engineering or related field.

• 3+ years of experience in hardware bring-up, integration and test.

• Strong hands-on experience using oscilloscopes, logic analyzers, and other lab instrumentation.

• Familiarity with embedded systems and firmware debugging.

• Strong proficiency working in Linux environments from the command line.

• Experience with common electrical interfaces (CAN, Ethernet, RS-422/485, UART, I²C)

• Basic scripting or programming ability (Python or C/C++).

• Understanding of real-time constraints and hardware-software integration challenges.

• A desire to work in a highly collaborative, fast-paced startup environment.  

You'll Stand Out: 

• Hands-on work with high-power, motor-driven, or battery-based systems

• Exposure to hardware-in-the-loop (HIL) or system-level test environments

• Working knowledge of embedded Linux platforms such as Yocto or Ubuntu-based systems

• Understanding of EMI and EMC considerations and field reliability challenges

• Involvement in field testing or operational deployments

• Proven ability to troubleshoot intermittent or system-level failures in complex hardware systems 

What We Offer: 

• Competitive salary

• ACS Equity Package

• Health, Dental, Vision Insurance

• Paid Time Off
