Array Labs is building a distributed radar imaging constellation to power the first accurate, real-time 3D model of the world.
The Hardware Engineering team at Array Labs is responsible for the analysis and design of our satellite and ground-station hardware platforms. These platforms tend to be a heterogeneous mix of various subsystems like compute, memory, peripherals with high-speed interfaces, RF, sensing, power management, navigation, and controls. The focus areas of the Hardware Engineering Team can be split into Aerospace/Avionics, Electrical/Electronics (EE), and Communications/Radar engineering. As a Power Management Design Engineer in the Communications/Radar team, you will own the simulation, design, prototyping, validation, and production of the critical power management system for the radar/communication payload on our satellites. You will be collaborating with RF, communications, and radar engineers to ensure the design satisfies the stringent requirements necessary to support Array Lab’s mission objectives.


  • Translating high-level power requirements into design specifications, evaluating design trade-offs, and defining high-efficiency power management architecture
  • Design and simulation of power supply circuits for the radar and communication subsystems
  • Work with vendors and partners to select components for cost-optimized designs
  • Create schematics and work closely with PCB designers to ensure proper layout for decoupling and power distribution
  • Develop and build prototypes of (sub-)circuits for testing and evaluation
  • Prepare comprehensive test plans and conduct thorough characterization of power management systems to validate performance
  • Debug issues related to power management functionality and performance
  • Collaborate with cross-functional teams, including antenna, RF, digital communication, and radar engineers, to ensure power management designs meet system-level requirements
  • Work with contract manufacturers for mass production, testing, calibration and integration of power management systems into our satellites

Basic Qualifications:

  • Master’s degree in electrical engineering, semiconductor device physics, or related field
  • 9+ years of hands-on experience building, testing, and delivering power supply circuits for high-power high-volume products
  • Strong background in analog circuit design, with a focus on switched-mode power converters and linear power regulators
  • Experience with circuit design and simulation tools such as Cadence (Spectre), OrCAD, PSPICE, LTspice, etc.
  • Hands-on experience with common lab equipment such as power supplies, oscilloscopes, signal generators, network analyzers, and logic analyzers
  • Experience with data analysis and programming tools such as MATLAB and/or Python
  • Excellent teamwork, communication, and documentation skills
  • Learns new concepts rapidly, completely, and in a self-directed manner
  • High level of self-motivation and personal accountability
  • Ability to work in a fast-paced environment under significant time constraints

Preferred Skills and Experience:

  • Ph.D. in electrical engineering, semiconductor device physics, or a related field
  • Experience with system power architecture
  • Experience with high-voltage high-power semiconductors (Si/SiC/GaN) and protection circuit design
  • Experience with design for fault tolerance and reliability
  • Experience with battery pack design, chargers, and battery management systems (BMS) is a plus
  • Familiarity with EMC requirements and EMI mitigation techniques relevant to power conversion systems
  • Experience with thermal analysis and simulation tools
  • Experience with parasitic extraction tools
  • Experience with schematic capture and board layout using CAD tools such as Altium Designer, Allegro, ORCAD, etc.
  • Hands-on tuning skills at the bench to optimize system performance

ITAR Requirements:

  • To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.
