Mechanical Engineer (Electronic Warfare)

Job Description:

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 Mechanical Engineer within our Electronic Warfare team, you will design the mechanical structures and packaging that house and protect our EW/SIGINT electronics in demanding field conditions - from concept to field deployment. You will translate RF and electronic constraints into robust mechanical designs, working hand-in-hand with hardware, software, GNC and ML teams.

Responsibilities

* RF Electronic Packaging: Design mechanical packaging for RF and high-power electronics (a core requirement of the role).
* Thermal Management: Design thermal solutions for high-power, high-density electronics.
* Shielding & Cabling: Integrate EMI/RF shielding and manage cable routing and constraints.
* Mechanical Design: Own mechanical design from concept through prototyping and validation.
* Technical Coordination: Collaborate across HW, software, GNC and ML teams on integration and technical interfaces.
* System Reviews & Documentation: Contribute to design and architecture reviews and maintain documentation and traceability.

Candidate Requirements

* Experience in RF electronic packaging is a must.
* Previous RF experience (radar, radio or EW) is a strong plus, to keep the associated constraints in mind (shielding, thermal, cabling, etc.).
* Strong background in mechanical design, thermal management and packaging.
* Broad engineering culture with understanding of electrical and embedded systems.
* MSc in Mechanical Engineering; PhD is a plus.
* 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
