## Job 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 http://allencontrolsystems.com.

Company Overview

Allen Control Systems (ACS) is a cutting-edge defense startup founded by two former Navy electrical engineers with a proven track record in robotics and software. We are developing an autonomous gun turret using advanced computer vision and control systems to precisely detect, track, and neutralize enemy drones.

With an engineering-first culture, ACS values technical excellence and innovation. Backed by our founders’ successful exits from two previous ventures acquired for a combined $180M in 2022, we are committed to ensuring that the groundbreaking technologies we develop will have a real-world impact.

## About The Role

We are looking for a Firmware Engineer to own the low-level embedded software that runs our autonomous aircraft in the field. This is a deep individual contributor role for someone with 4+ years of industry experience who can operate at the architecture and design level from day one. You will make real decisions about bare-metal versus RTOS tradeoffs, sensor and peripheral integration, deployment strategies for fielded aircraft, and the HIL testing infrastructure that validates it all. You are expected to document and justify those decisions with the same rigor you apply to the code itself.

## What You’ll Do

- Own the architecture and implementation of time- and safety-critical embedded firmware on STM32-based platforms; evaluate existing firmware ecosystems and make well-reasoned decisions about what to carry forward versus redesign from scratch.
- Write drivers for sensors and peripherals; select and configure communication protocols including CAN, I2C, UART, and Ethernet appropriate to each use case.
- Determine and implement deployment strategies for fielded aircraft, including bootloader design and over-the-air or field update approaches.
- Set up and maintain hardware-in-the-loop testing infrastructure; produce thorough design documentation that captures architectural decisions, protocol selections, and tradeoffs clearly enough to stand on their own.

## What You’ll Need

- 4+ years of industry experience in embedded firmware development; fluency in C and C++ is required.
- Deep understanding of bare-metal and RTOS embedded architectures; strong working knowledge of embedded communication protocols including CAN, I2C, UART, and Ethernet and the ability to select the right tool for each application.
- Solid experience with bootloader design and firmware deployment for fielded systems; experience setting up hardware-in-the-loop testing environments.
- High standards for code quality and correctness; demonstrated ability to document and justify architectural decisions clearly and concisely so that design rationale is durable and legible to others.

You’ll Stand Out

- Background in aerospace, defense, or aviation; prior experience with HIL testing of aircraft or flight control systems specifically.
- Hands-on experience with STM32 microcontrollers and associated toolchains.
- Experience with safety-critical or DO-178C certified software development practices.
- Exposure to autonomous systems, robotics, or UAS platforms at the firmware level.

## What We Offer

- Competitive salary
- ACS Equity Package
- Health, Dental, Vision Insurance
- Paid Time Off

## About Allen Control Systems

## Company Overview
- **One-liner**: Allen Control Systems (ACS) is a defense technology company building autonomous robotic weapon stations to counter drone swarms with cost-effective, AI-driven precision.
- **Entity Type**: Private (Series A; recent $200M round at $2.2B valuation)
- **Headquarters**: Austin, Texas, USA (also office in Alexandria, Virginia)
- **Founded**: 2023 (seed round closed April 2024)
- **Founders**: Luke Allen (CTO), Mike Wior (CEO), and Steve Simoni (President) – all U.S. Navy veterans and nuclear engineers

## Core Business
- **Primary industries**: Defense and space manufacturing, counter-unmanned aircraft systems (C-UAS), robotics, AI/computer vision
- **Target customers**: U.S. Department of Defense, allied militaries, national security agencies (B2G)
- **Mission/purpose**: To completely change battlefield economics by lowering the cost per kill of a drone to a few dollars, using existing weapon systems enhanced by proprietary hardware and software.

## Products & Services
- **Bullfrog™ Weapon Stations**: A family of autonomous, remotely operated weapon mounts (variants: M240C, M230, M2, M134, M240) that can be integrated with existing military platforms. Key features:
  - Passive sensing (no radar required) for stealth operations
  - Open architecture for integration with any C2 system
  - AI/ML-based fire control for precise targeting of Group 1–3+ UAS, including swarms and non-jammable drones
  - Effective range up to 1,500m depending on variant
- **Autonomous Fire Control Software**: Machine vision and synthetic data generation engine that continuously updates threat libraries and enables accurate engagement without human intervention.
- **Synthetic Data Training Pipeline**: Generates simulated threat scenarios to keep the system current with evolving drone threats.

## Market Standing
- **Valuation**: $2.2 billion (per 2026 $200M funding round; reported by company and media)
