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.
