Mechanical Engineering Intern, 2027

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 .
