Ready to make connectivity from space universally accessible, secure and actionable? Then you’ve come to the right place!

E-Space is bridging Earth and space to enable hyper-scaled deployments of space-powered Internet of Things (IoT) solutions and services. We are fundamentally changing the design, economics, manufacturing, coverage limitations and service delivery associated with traditional satellite and terrestrial IoT systems.

By building a highly-advanced low Earth orbit (LEO) space system—with a unique antenna design, highly sustainable spacecraft system and low-cost, small portable end-user devices—we can extend global satellite coverage, capacity and connectivity beyond legacy space services to provide a new kind of IoT platform that lets users sense, track, connect and act on information gathered, anywhere.

We’re intentional, we’re unapologetically curious and we’re 100% committed to saving space, protecting our planet and turning connectivity into actionable intelligence.

We are looking for a Senior 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.

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).

BS +5 years / MS +3 years in Electrical Engineering, Electronics, or related field.

Minimum 3 years of professional experience in end-to-end PCBA design, production, and testing.

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.

Familiarity with common spacecraft communication interfaces: SPI, I²C, UART, CAN, RS-422/485.Previous experience in the space, aerospace, or defense industry.

While we welcome candidates with global experience, please note that English is the language we conduct our business in, and application submissions will need to be in English or both English and French to be reviewed by our global team.
