Power Electronics Engineer

Senior Electronics Engineer (Power Electronics & High‑Voltage)

iO Associates are partnered with a growing deep‑tech company in the space sector, developing advanced propulsion hardware for small satellites. As they scale from R&D into production, they are strengthening their electronics capability and are now seeking a Senior Electronics Engineer with deep expertise in power electronics and high‑voltage systems to support this next phase. This is a hands‑on, hardware‑focused role based near Paris.

Key Responsibilities

• Design and develop advanced electronics hardware with a strong focus on power electronics (e.g. DC/DC converters, flyback topologies, power conversion systems)
• Lead technical work on high‑voltage and high‑reliability electronic systems
• Ensure robust design against EMC, lightning and electrical transient effects, particularly for harsh environments
• Support system integration, testing and validation activities
• Drive key technical decisions balancing performance, reliability, safety and manufacturability
• Contribute to the transition from R&D to production, including DFM and industrialisation
• Collaborate closely with multidisciplinary engineering teams

Your Profile

• Experienced Electronics Engineer with 10-20+ years of experience, ideally in demanding or high‑reliability sectors
• Strong expertise in power electronics design, including converters (DC/DC, flyback, etc.)
• Proven experience working with high‑voltage systems or electrically harsh environments
• Deep understanding of electronics protection, including EMC and protection against lightning/transient effects (e.g. Class III/IV environments)
• Predominantly hardware‑focused, hands‑on engineering approach
• Background in sectors such as space, aerospace, automotive, power electronics, or scientific instrumentation
• Comfortable operating in an R&D environment transitioning to industrial scale‑up
• French language skills are desirable

Why Apply?

• Work on cutting‑edge space propulsion hardware with real flight applications
• Join a highly expert team where your contribution has direct impact
• Play a key role in scaling a company from research to industrial production
• Develop deep expertise in a highly specialised and technically complex field
