Berkeley Fall 2026 Career Fair

About the role

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.

Location and duration

Location: Austin, TX (on-site)
Duration: Summer 2027 (~10–12 weeks)

Pay

Paid internship with competitive pay

What You Could Work On

• Electrical, Software, Computer Vision, Machine Learning, Mechanical, Manufacturing and Supply chain interests
• Software that connects sensors, computer vision models, and control systems into a working autonomous weapon system
• Real-time systems where latency and reliability actually matter — not just a nice-to-have
• Tools and interfaces engineers and operators use every day, from embedded Linux applications to internal tooling
• Full-stack or backend projects supporting engineering, manufacturing, or field operations

What We're Looking For

• Currently pursuing a degree in Computer Science, Software Engineering, or a related field
• Coursework or project experience in one or more of C++, Python, Kotlin, or Java
• Curiosity about real-time, embedded, or systems-level software — you don't need to be an expert yet
• A builder's mindset: you'd rather ship something and iterate than wait for a perfect spec

Why ACS

• Direct impact: your work ships on hardware being fielded to protect real people — not stuck in a slide deck
• Real ownership: no red tape. You'll work directly with the engineers building Bullfrog, from day one
• Small team, big scope: at a startup this size, interns take on real problems, not busywork
• Mentorship from engineers who've designed and fielded real defense systems

Benefits

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