Lead Spacecraft EPS Engineer: Own the Power System

PAVE Space SA; Villeneuve (VD); À distance; CHF 90 000 - 130 000; Plein temps

Résumé du poste

PAVE Space SA in Villeneuve (VD) is seeking an Electrical Engineer to own the spacecraft EPS, driving from approved architecture to flight-ready hardware.

You will size and specify solar arrays, batteries, PCUs, and power distribution, define redundancy, and manage interfaces, harnesses, and suppliers. This on-site role offers broad ownership and hands-on testing on a Swiss space program.

Qualifications

• 2+ years of proven experience in spacecraft EPS, avionics power, or high-reliability embedded power systems (space preferred).
• Experience sizing and selecting solar arrays, batteries, PCUs/DC-DC converters, and power distribution and protection elements
• Ability to create and maintain power budgets, margins, and mission power mode concepts
• Experience with harness design and documentation: connectors, pinouts, routing constraints, manufacturing drawings
• Familiarity with EMC/EMI and grounding principles for mixed RF, power, and digital subsystems
• Hands-on experience with integration and testing, including lab equipment (PSU, electronic load, oscilloscope, DMM) and troubleshooting
• Understanding of space constraints: thermal, radiation context, reliability, derating, workmanship
• Fluent English (our working language)
• Nice to have: ECSS standards or similar space product assurance, battery safety/qualification exposure, EGSE/test procedures, TVAC/vibration test support, French language skills

Responsabilités

• Own the Electrical Power System, from architecture decisions to flight-ready hardware.
• Size and specify solar arrays, battery pack, and PCUs/DC-DC converters.
• Define the power architecture in full, including redundancy, protection, and power modes.
• Produce and maintain the power budget, margins, and operating scenarios.
• Manage electrical interfaces between subsystems: connectors, pinouts, ICDs, grounding.
• Define and design the spacecraft harness including routing constraints and drawings.
• Manage EPS component suppliers end to end: specification, procurement, follow-up, acceptance, non-conformance.
• Contribute hands-on to AIT and test campaigns: troubleshooting and environmental testing support
