Job Description
We are looking for an Electronics Engineer to join our GNC Hardware team. You will design, develop, and validate electronic boards and power stages for compact, high-performance space mechanisms and assemblies. Your scope covers the full electronics lifecycle: from architecture definition and schematic capture through PCB layout, prototype bring-up, and qualification support. You will work at the intersection of power electronics, embedded systems, and mechanical integration in a demanding space environment.
Design and implement motor control electronics and control loops (BLDC and other topologies), including FPGA-based motor control architectures.
Define the architecture of PCBAs for GNC hardware devices, including power conversion, motor drive stages, signal conditioning, and communication interfaces.
Perform schematic capture and detailed circuit design for power and mixed-signal boards.
Design multi-layer PCB layouts (including mixed-signals, DC-DC converters, H-bridge drivers, and current control loops) taking into account EMC, thermal management, and space-grade constraints.
Select and qualify PCBAs for space applications (radiation tolerance, derating, thermal, outgassing).
Produce thorough design documentation: schematics, BOMs, design justification files, and interface control documents.
Bring up prototype boards: power-on sequencing, functional verification, anomaly investigation and resolution.
Support test campaigns, including test board design, instrumentation, and data analysis.
Collaborate with the mechanical and test teams on integration, harnessing, and thermal interfaces.
Support environmental qualification activities (vibration, thermal, EMC).
5–8 years of professional experience in end-to-end PCBA design, production, and testing.
Proven experience in motor control electronics, including BLDC drives and other motor topologies (current/voltage control loops, commutation, drive stages).
Proficiency with Altium Designer (schematic capture, multi-layer PCB layout, design rule management).
Solid background in power electronics (DC-DC conversion, motor drive topologies, current/voltage control loops) and analog/mixed-signal design (op-amp circuits, ADC/DAC interfaces, filtering, grounding strategies).
Experience with board bring-up, debugging, and validation using lab instruments (oscilloscopes, multimeters, power supplies, thermal cameras).
Familiarity with space or high-reliability electronics constraints: component derating, radiation awareness, thermal management, EMC design practices.
Autonomous, rigorous, and comfortable in a fast-paced startup environment.
Hands-on experience with FPGA-based motor control (control logic implementation, sensor interfacing).
Familiarity with common spacecraft communication interfaces: SPI, I²C, UART, CAN, RS-422/485.Previous experience in the space, aerospace, or defense industry.
Space experience is a plus but not mandatory.
