About Us
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.
About the Role
As a Hardware (Electronics) Engineer within our Electronic Warfare team, you will design and develop the RF hardware and electronic front-ends at the core of our electronic warfare and signal intelligence systems - from concept to field deployment. You will work hand-in-hand with system, software and mechanical teams to turn architecture needs into robust, high-performance hardware, and to ensure overall performance, robustness and reliability.
Responsibilities
We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
