Job summary

Starpath seeks a Power Electronics Avionics Engineer for the Starlight product to own the power converter from architecture to flight readiness. You will select topologies, design magnetic components, drive circuits, sensing, and EMI/thermal interfaces for a spaceflight solar array.

You will model, simulate, test, and iterate with systems, mechanical, and test engineers to ensure robust performance in launch and space environments. This role is on site in Carson, CA.

Qualifications

• 3+ years designing power electronics or converters.
• Experience taking a power converter from architecture to prototype, bring‑up, and testing.
• Strong grounding, EMI/EMC fundamentals and power integrity knowledge.
• Space-grade hardware experience is a plus.

Responsibilities

• Own the design of a power converter for the Starlight solar array product from requirements through flight readiness.
• Translate system requirements into converter architecture and detailed electrical requirements.
• Design switching power stages, gate-drive circuits, magnetics, control loops, sensing, filtering, and protection circuitry.
• Perform circuit modeling, simulation, stability analysis, component derating, and worst‑case analysis.
• Own schematic capture and power‑electronics PCB layout, with high‑current paths, grounding, and thermal/EMI considerations.
• Build, bring up, characterize, and debug converter prototypes.
• Develop and execute tests for efficiency, regulation, transient response, stability, thermal performance, and fault behavior.
• Design for launch and space environments, including vibration, thermal vacuum, radiation, and EMC.
• Define electrical interfaces between solar array, converter, spacecraft power system, and avionics.
• Investigate failures, determine root causes, and implement design improvements.
• Partner with manufacturing and supply‑chain to transition the design into production.
• Maintain schematics, BOMs, analyses, and test/qualification records.
