About the role

Harmattan AI is developing new hardware within the Launcher module (field-deployable drone launchers). The role focuses on end-to-end electronics design for mixed-signal and power boards, with emphasis on robustness in demanding field environments and production-friendly solutions.

Responsibilities

  • Schematic Design - Design complete schematics for mixed-signal and power boards, from power stages to digital and communication sections.
  • PCB Layout & Routing - Perform or lead board placement and routing with attention to signal integrity, EMC, and power-path constraints.
  • Power & Thermal Architecture - Define and validate the power architecture of the product and the thermal strategy, including battery temperature management.
  • Environmental Robustness - Ensure the electronics withstand outdoor deployment conditions and define the associated qualification plan.
  • Component Selection & BOM Optimization - Select components with cost, availability, and reliability in mind; drive BOM cost reduction for mass production volumes.
  • Hardware Bring-up & Debug - Lead board bring-up, debug issues with oscilloscopes, power bench equipment, and other bench equipment; write bring-up scripts when needed.
  • EMC & Safety Compliance - Address EMC challenges; ensure signal integrity across the board and electrical safety of the power and battery sections.
  • Collaboration with Embedded SW - Work closely with the embedded software engineer to define hardware/software interfaces; support firmware bring-up.
  • Collaboration with Mechanical - Ensure seamless PCB integration into mechanical enclosures (connectors, mounting, thermal, sealing, shielding).
  • Supplier & Manufacturing Ramp-up - Qualify PCB manufacturers and assembly houses; support DFM/DFA review for production; manage NPI transitions.
  • Documentation - Maintain schematics, layout files, test procedures, and hardware specifications.

Qualifications

  • PCB schematic and layout design (Altium Designer preferred)
  • Power electronics design: ~300 W DC/DC conversion, protection, derating, efficiency and thermal budgets
  • Thermal regulation: temperature sensing and control loops, battery storage temperature management, heatsinking
  • Power over Ethernet (IEEE 802.3af/at/bt): combined power and data delivery, isolation, cable budgets
  • Mixed-signal design: power management, MCU interfaces, communication buses (SPI, I2C, UART, USB, CAN, Ethernet)
  • Hardware bring-up and debug: bench equipment proficiency
  • DFM/DFA for PCB manufacturing and assembly
  • Component selection and BOM management
  • Experience in lightning and surge protection is a plus
