Software Engineering Intern, 2027

Employer description

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.

Software Engineer Intern - Summer 2026

Our interns aren’t fetching coffee or shadowing — they’re working alongside the same engineers building the systems we ship. This is early-career work with real stakes.

Location: Austin, TX (on-site)

Duration: Summer 2027 (~10-12 wks)

Pay: Paid internship

What You Could Work On:

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.
