Harmattan AI is a defense prime building autonomous and scalable defense systems. Following a $200M Series B at $1.4B valuation, the company is expanding teams to deliver mission-critical systems to allied forces.
The Ground Control System (GCS) team is developing new hardware products including ruggedized drone controllers and long-range RF systems for demanding field environments. These products require complex PCB design integrating RF modules, microcontrollers, power management, and communication interfaces—optimized for cost at volume.
You will own electronics design end-to-end, from schematic through production. This is a senior individual contributor role in a small, autonomous team environment.
Key Responsibilities:
- Design complete schematics for mixed-signal and RF boards, covering power, digital, and RF sections
- Perform PCB layout and routing with attention to signal integrity, EMC, and RF constraints (6-8 layer boards, controlled impedance, ground planes, RF traces)
- Select components and optimize BOM for cost, availability, and reliability at mass production volumes
- Lead board bring-up and debug using oscilloscopes, spectrum analyzers, and bench equipment; write bring-up scripts as needed
- Address EMC challenges and ensure correct RF performance (antenna impedance matching, power levels)
- Collaborate closely with embedded software engineers to define hardware/software interfaces and support firmware bring-up
- Work with mechanical teams to ensure seamless PCB integration into enclosures (connectors, mounting, thermal, shielding)
- Qualify PCB manufacturers and assembly partners; support DFM/DFA reviews for production; manage NPI transitions
- Maintain schematics, layout files, test procedures, and hardware specifications
Requirements:
- Proven experience designing and shipping complex PCBs into production, ideally mixing digital and power domains
- PCB schematic and layout design expertise (Altium Designer preferred)
- RF PCB design: controlled impedance, antenna matching, EMC management
- Mixed-signal design: power management, MCU interfaces, communication buses (SPI, I2C, UART, USB, CAN)
- Hardware bring-up and debug proficiency with bench equipment
- DFM/DFA knowledge for PCB manufacturing and assembly
- Component selection and BOM management experience
- Rigorous approach to schematics, layout, and bring-up with strong instinct for cost and manufacturability
- Ability to work autonomously in a small team and bridge hardware and firmware domains
