Autonomous defense systems and C2 platforms
Harmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces.
Our work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected.
As a Mechatronics Engineer, you will play a key role in designing and developing the hardware and software that power our automated testing and inspection platforms. Working within the R&D department, you will create robust, scalable automation tools that support both product development and manufacturing operations. Your primary focus will be mechanical development for test automation, while also collaborating on software and electrical integration aspects of test systems.
Test Fixture Development – Design, prototype, and maintain mechanical test fixtures, jigs, and tooling built for reliability, reproducibility, and repeatable operator use.
Mechanical Integration – Design the physical integration of sensors, actuators, cameras, and other instruments into test stations, in collaboration with the Automation Software Engineers who own the control and software layer. Occasional software integration is also possible based on candidate skillset.
ATE Integration — Specify and integrate custom solutions from external vendors for testing equipment/instrumentation (RF housings, GNSS, optical systems…).
Cross-Team Collaboration – Work closely with product development, manufacturing, and the Infrastructure & Deployment engineer to deliver robust, maintainable, and scalable automation solutions for the factory and field.
MSc in Mechanical, Mechatronics, or related engineering field.
Excellent CAD skills with experience in rapid prototyping and robust solution implementation (SolidWorks, Catia or similar).
Experience working with external vendors and machine shops for part fabrication and test equipment selection.
Comfortable performing soldering, wiring, and small-scale electrical circuit work for test system integration.
Experience working with electronic assemblies (PCBAs); familiarity with pogo-pin / bed-of-nails fixturing is a strong plus.
Knowledge of RF housing design and specifications is a plus.
Strong problem-solving skills and ability to design practical, robust engineering solutions.
Excellent communication skills and proven ability to collaborate across multidisciplinary teams.

We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
Autonomous defense systems and C2 platforms
Harmattan AI builds vertically integrated autonomous defense systems for NATO and allied forces. Its products include layered air defence, coordinated ISR and strike UAVs, electronic-warfare tools, and command-and-control platforms, all powered by a software-defined autonomy stack. The systems are designed to operate together, with autonomous decision-making, sensor fusion, and mission execution through its C2 framework. The company differentiates itself through large-scale industrial manufacturing, secured Programs of Record with European and UK defense ministries, and a strategic partnership with Dassault Aviation to embed Harmattan’s controlled autonomy into combat-air systems such as Rafale F5 and UCAS. The goal is to provide trusted, scalable autonomous solutions for defense missions, expanding globally and embedding autonomy into partner platforms to strengthen allied capabilities.
