Auckland, NZ · Full-time · NZ$160,000 – NZ$240,000

About this role

Rocket Lab is an end-to-end space company delivering responsive launch services, spacecraft design, manufacturing, payloads, and satellite components to open access to space. The rockets and satellites enable ambitious missions for scientific exploration, Earth observation, climate change, national security, and technology demonstrations. Electron has delivered over 230 satellites to orbit while developing Neutron for larger deployments.

The Space Systems team designs and builds complete satellites and components like solar panels, flight software, reaction wheels, star trackers, separation systems, and radios for commercial, government, and defense missions. As Senior Power Electronics Engineer, you will lead design, development, and verification of high-power flight electronics for ion propulsion power processing units and high-voltage distribution systems. You will own projects from concept through production for robust hardware in space environments.

Daily work involves architecting DC-DC converters, power distribution units, and custom magnetics while meeting efficiency, thermal, and EMC requirements. You will perform electrical analyses including Worst-Case Analysis, FIDES, Power Integrity, thermal simulations, and high-voltage stress analysis. Expertise guides technical decisions across multiple flight programs.

Join engineers and technicians building satellites for NASA Moon and Mars missions and components for James Webb Space Telescope. Contribute to spacecraft avionics integrity in high-stakes space environments. Advance propulsion and power systems for cutting-edge missions.

Requirements

  • Expertise in high-voltage DC-DC converters and power processing units for space applications
  • Experience designing custom magnetics such as transformers and inductors for high-power electronics
  • Knowledge of thermal management, EMI/EMC compliance, and high-voltage isolation in avionics
  • Proficiency in electrical analyses like Worst-Case Analysis, Power Integrity, and stress testing
  • Familiarity with space-grade components and qualification for radiation, outgassing, and corona risks
  • Skills in precision current/voltage control and arc suppression for propulsion systems
  • Understanding of power topologies and efficiency optimization for spacecraft environments

Responsibilities

  • Own the full development lifecycle of high-reliability, high-voltage power processing units for ion propulsion systems
  • Architect and design high-power DC-DC converters and power distribution electronics for mission-critical propulsion applications
  • Design and prototype vehicle-level high-voltage distribution units and interface modules with circuit protection and arc suppression
  • Perform comprehensive electrical analyses including Worst-Case Analysis, FIDES, Power Integrity, thermal simulations, and high-voltage stress analysis
  • Select space-grade high-voltage components addressing radiation tolerance, corona discharge, outgassing, and lead-time risks
  • Lead the design of complex power electronics including custom magnetics, switching regulator optimization, and high-voltage filtering
  • Develop grounding, bonding, and EMI/EMC strategies for high-power integrated avionics suites
