Embedded Electrical Engineer - SoM

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 an Embedded Electrical Engineer at Harmattan AI, you will join the R&D team to design the compute modules and associated boards used across our platforms. You will own these designs end-to-end, from system architecture and schematic through layout guidance, fabrication, bring-up, and qualification. This is a high-impact role that combines demanding high-speed design work with hands-on bench work, taking hardware from a first prototype through to boards that fly. Responsibilities Board Design: Design SoMs, baseboards, and test boards for our compute platforms. High-Speed Digital Design: Design around high-end application processors, covering PCIe, 10 Gb Ethernet, USB 3.x, and MIPI, managing layout constraints and signal integrity. Power Design: Design power trees, sequencing, and conversion topologies, and verify power-up and power-down behaviour. Design Reviews: Prepare and lead design reviews at eac
