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

• RF Front-End Design: Design and develop radio and radar RF front-ends, from specification through to validation.

• Hardware Architecture: Drive the hardware architecture of EW/SIGINT systems, ensuring performance, robustness and manufacturability.

• High-Power & High-Voltage Electronics: Design high-power switching supplies (including narrow pulse generation) and high-voltage PCBs, supplies and shielding.

• Integration & Validation: Lead board bring-up, RF integration, prototyping and validation against performance targets.

• Technical Coordination: Collaborate across software, mechanical, GNC and ML teams on system integration and technical interfaces.

• System Reviews & Documentation: Contribute to design and architecture reviews, maintaining consistency between requirements, design and testing.

Candidate Requirements

• Strong background in RF hardware design is mandatory, including radio or radar front-end design.

• No prior Electronic Warfare experience required.

• Experience in RF integration is a plus.

• Experience with high-power switching supplies (narrow pulse generation) is a definite plus.

• Experience with high-voltage PCB / supply design and shielding.

• MSc in Electrical / Electronics Engineering; PhD is a plus.

• Broad engineering culture with understanding of mechanical, software and embedded systems.

• Rigorous, structured and mission-driven mindset with strong analytical skills.

• Excellent communication and documentation abilities.

We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
