Test 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.

Position Overview

As a Test Engineer, your primary mission is to own product acceptance and end-of-line (EOL) test systems as we transition from development into scaled production. This role is responsible for building and maintaining reliable, repeatable test processes that ensure every unit shipped meets performance and quality expectations. You will work closely with manufacturing, quality, and engineering to improve yield, resolve failures, and enable increasing production rates. This is a hands-on role. You will be expected to both design systems and step in to support execution when needed.

What You'll Do

• Own development and maintenance of product acceptance and EOL test systems

• Design and implement test processes that are robust, repeatable, and scalable

• Drive improvements in test throughput to support increasing production rates

• Analyze test data to identify yield issues, failure trends, and opportunities for improvement

• Lead root cause investigations and implement corrective actions

• Design fixtures, instrumentation, and automation to improve consistency and reduce manual effort

• Partner with engineering to improve testability and manufacturability

• Work closely with manufacturing and quality teams to resolve issues and maintain production flow

• Develop and maintain test procedures, documentation, and work instructions

• Continuously improve test systems to increase reliability, uptime, and scalability

What You'll Need

• Bachelor’s degree in Electrical, Mechanical, or related engineering field (or equivalent experience)

• 3+ years of experience in hardware testing, preferably in a production or manufacturing environment

• Experience with test instrumentation (DMMs, oscilloscopes, DAQ systems, power supplies, etc.)

• Ability to analyze test data and identify trends impacting yield and performance

• Experience with root cause analysis and implementing corrective actions

• Strong problem-solving skills and attention to detail

• Ability to work cross-functionally in a fast-paced, production-driven environment

• Willingness to be hands-on and support test execution when needed

You’ll Stand Out

• You have experience building or supporting EOL/production test systems

• You’ve improved test throughput, yield, or system reliability in a measurable way

• You have experience with test automation (Python, C++, or similar)

• You’ve designed fixtures or hardware interfaces for production testing

• You think in terms of systems, scalability, and failure modes – not just test execution

• You’ve worked in a high-growth or startup environment

What We Offer:

• Competitive salary

• ACS Equity Package

• Health, Dental, and Vision Insurance

• Paid Time Off
