Power Systems Engineer

About the CompanyAt 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. Along the way, we seek to leverage the technologies we build to provide additional value across other domains. We offer a unique opportunity to join an exciting team looking to expand humanity's capabilities in space.Job DescriptionAs 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.ResponsibilitiesOwn power subsystems end-to-end-from requirements definition and architecture through design, manufacturing, integration, and in-flight operationsDesign DC/DC converters, power distribution units (PDUs), battery management systems (BMS), and solar array interfaces for high-reliability space applicationsModel and simulate power system performance under nominal and fault conditions using tools such as LTspice, PLECS, or MATLAB/SimulinkConduct PCB-level design and layout for power electronics with thermal, radiation, and EMI/EMC constraints in mindDrive root-cause analysis and troubleshooting of power-related issues in spacecraft and ground systemsDevelop test plans and automate validation for high-voltage and high-current systemsWork with systems, mechanical, software, and GNC teams to ensure power architecture supports mission-level goals and spacecraft performanceContribute to avionics team best practices, including documentation, design reviews, and hardware bring-up processesBasic QualificationsBachelor's degree in Electrical Engineering or a related fieldExperience designing and testing power electronics (DC/DC, power conversion, energy storage, etc.)Familiarity with power systems modeling and simulation toolsProficiency with test equipment such as oscilloscopes, electronic loads, power analyzers, and logic analyzersExperience with electrical CAD tools (Altium, KiCad, OrCAD, etc.)Strong organizational and time-management skills in a fast-paced environmentWillingness to work extended hours when required to support critical milestonesAbility to work onsite in Seal Beach, CAPreferred Skills and Experience3+ years of experience in power electronics for aerospace, automotive, or other high-reliability systemsExperience with space-rated power architectures and understanding of spacecraft energy budgetsFamiliarity with battery chemistries (Li-ion, LiFePO4, etc.) and charging algorithmsKnowledge of fault protection, redundancy, and reliability in power systemsHands-on experience bringing up and debugging high-power boards and systemsUnderstanding of EMI/EMC compliance and mitigation strategiesComfort writing test scripts and automating lab workflows (Python preferred)Experience with wire harness design and integration for power-heavy systemsBenefits100% paid medical, dental, and life insurance coverageVision and FSA benefits available3 weeks of PTO + 1 week of sick time10 paid holidaysRetirement savings plan - 401(k), with company matchEquity on the ground floor of a startupSalaryLevel I: $94,000 - $121,500Level II: $118,000 - $142,500Level III: $138,000 - $171,500Level IV: $168,000 - $185,500ITAR RequirementsTo conform to U.S. Government export regulations, including the International Traffic in Arms Regulations (ITAR), you must be a (i) U.S. citizen or national, (ii) U.S. lawful permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C. § 1157, or (iv) Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Government.Equal Opportunity StatementWe are an equal opportunity employer and value diversity at our company.
