À propos de ce poste Power Electronics Engineer chez Espace
Espace · Saratoga, CA
Ready to make connectivity from space universally accessible, secure and actionable? Then you’ve come to the right place!
E-Space is bridging Earth and space to enable hyper-scaled deployments of Internet of Things (IoT) solutions and services. We are building a highly-advanced low Earth orbit (LEO) space system that will fundamentally change the design, economics, manufacturing and service delivery associated with traditional satellite and terrestrial IoT systems.
We’re intentional, we’re unapologetically curious and we’re 100% committed to innovate space-based communications and deliver actionable intelligence that will expand global economies, protect space and our planet and enhance our overall quality of life.
We are seeking Power Electronics Engineers to design and qualify power subsystems for a next-generation satellite constellation. You will be responsible for power distribution, battery management, charge regulation, and power conditioning circuits across multiple avionics boards. The role demands deep analog and power design expertise, combined with the rigor required for space-grade hardware.
Key Responsibilities:
- Design DC/DC converter power stages including switching device selection, filter design, driver circuits, and magnetics.
- Develop battery management and charge regulation circuits with appropriate safety, cycle-life, and charging-profile considerations.
- Perform control-loop modeling and compensation for analog and digitally controlled power supplies.
- Design fault-protection circuits including overcurrent break, current clamp, overvoltage clamp, crowbar, and foldback protection.
- Implement current, voltage, and temperature sensing circuits with filtering, threshold triggers, and ADC integration.
- Perform component derating analysis and design for radiation tolerance across all power subsystems.
- Develop load accounting, mode-based power consumption estimates, and concept-of-operations power budgets.
- Design power distribution networks with DC load switches, telemetry, and protection for multiple subsystem loads.
- Collaborate with PCB layout engineers on power supply layout optimization (loop area minimization, noise reduction, switching node management).
- Support FPGA and digital teams with power supply sequencing, support circuitry, and power integrity requirements.
Required Qualifications:
Preferred Qualifications:
- Experience with satellite or spacecraft power subsystems (PDU, BMS, BCR, solar array interfaces).
- Background in lithium-ion battery performance, safety, and packaging considerations.
- Experience with motor-drive design and inductive-load drivers (solenoids, magnetorquers).
- Familiarity with orbit-geometry analysis for power-balance and eclipse-cycle planning.
- Understanding of solar panel I-V characteristics, harvesting topologies, and degradation modeling.
- Supply-chain awareness including long-lead component identification and pre-buy strategies.
Tools & Technologies:
- SPICE-based circuit simulation (LTSpice, PSpice, or equivalent)
- Altium Designer (schematic capture)
- HyperLynx PI (power integrity analysis)
- MATLAB or Python for control-loop modeling and power budget analysis
This is a full time, exempt position, based out of our Saratoga office. The total compensation packaged will be determined by various factors such as your relevant job-related knowledge, skills, and experience.
We are redefining how satellites are designed, manufactured and used—so we’re looking for candidates with passion, deep knowledge and direct experience on LEO satellite component development, design and in-orbit activities. If that’s your experience – then we’ll be immediately wow-ed.
E-Space is not currently able to provide employment sponsorship for candidates who do not hold work authorization for the location of this role.
Why E-Space is right for you:
As a member of our team, you will play a crucial role in driving our success. Our team members have a strong sense of dedication and responsibility; this includes a strong commitment to our mission to create an entirely new suite of global capabilities to improve lives, business efficiencies and build a smarter planet. This means that there will be times when extra hours, including nights and weekends, may be needed to meet critical deadlines and mission goals. In return, we offer a dynamic work environment with opportunities for professional growth and development and the chance to make a meaningful impact in a high-growth industry.
We want you to make the most of your journey at E-Space. That’s why we support and invest in the physical, emotional and financial well-being of our team members and their families. Some of what you can expect when working at E-Space:
• An opportunity to really make a difference
