Join to apply for the Power System Engineer role at AstroForge

At AstroForge, our mission is to make space resources accessible on Earth. We mine asteroids to extract valuable minerals in space at a lower cost and smaller carbon footprint than current terrestrial mining methods. We offer a unique opportunity to join an exciting team looking to expand humanity’s capabilities in space.

Job Description

As an Electrical Engineer focused on Power Systems at AstroForge, you will play a key role in designing and delivering reliable, high-efficiency spacecraft power electronics. You will collaborate across engineering disciplines to architect, build, and test the power systems that drive the first successful asteroid mining vehicle—from energy storage to distribution to conversion.

Responsibilities

Own power subsystems end-to-end—from requirements definition and architecture through design, manufacturing, integration, and in-flight operations
Design DC/DC converters, power distribution units (PDUs), battery management systems (BMS), and solar array interfaces for high-reliability space applications
Model and simulate power system performance under nominal and fault conditions using tools such as LTspice, PLECS, or MATLAB/Simulink
Conduct PCB-level design and layout for power electronics with thermal, radiation, and EMI/EMC constraints in mind
Drive root-cause analysis and troubleshooting of power-related issues in spacecraft and ground systems
Develop test plans and automate validation for high-voltage and high-current systems
Work with systems, mechanical, software, and GNC teams to ensure power architecture supports mission-level goals and spacecraft performance
Contribute to avionics team best practices, including documentation, design reviews, and hardware bring-up processes

Basic Qualifications

Bachelor’s degree in Electrical Engineering or a related field
Experience designing and testing power electronics (DC/DC, power conversion, energy storage, etc.)
Familiarity with power systems modeling and simulation tools
Proficiency with test equipment such as oscilloscopes, electronic loads, power analyzers, and logic analyzers
Experience with electrical CAD tools (Altium, KiCad, OrCAD, etc.)
Strong organizational and time-management skills in a fast-paced environment
Willingness to work extended hours when required to support critical milestones
Ability to work onsite in Seal Beach, CA

Preferred Skills and Experience

3+ years of experience in power electronics for aerospace, automotive, or other high-reliability systems
Experience with space-rated power architectures and understanding of spacecraft energy budgets
Familiarity with battery chemistries (Li-ion, LiFePO4, etc.) and charging algorithms
Knowledge of fault protection, redundancy, and reliability in power systems
Hands-on experience bringing up and debugging high-power boards and systems
Understanding of EMI/EMC compliance and mitigation strategies
Comfort writing test scripts and automating lab workflows (Python preferred)
Experience with wire harness design and integration for power-heavy systems
100% paid medical, dental, and life insurance coverage
Vision and FSA benefits available
3 weeks of PTO + 1 week of sick time
10 paid holidays
Retirement savings plan – 401(k), with company match
