In this role, you’ll be responsible for architecting and validating robust power electronics, including DC-DC converters, power distribution units, and energy storage systems, that serve as the electrical core of scalable orbital infrastructure. This is a rare opportunity to step in early, contribute to hardware that's already flying with real customers, and influence spacecraft power systems from first principles through production. You’ll join a nimble, fast-growing team that’s tackling the complexities of building space systems at scale. Our current work spans both commercial and government contracts, with a strong emphasis on modularity, reliability, and manufacturability. If you’re looking for a high-impact role that blends deep technical ownership with hands-on engineering, this is your chance to shape the future of power systems in orbit.About UsWe’re designing a fundamentally new spacecraft architecture aimed at simplifying how satellites are built, deployed, and operated. Our compact, modular platform reimagines traditional bus systems, integrating power, control, and communications into a streamlined form factor built for mass production. With a growing portfolio of national security and commercial customers, and an experienced founding team drawn from top aerospace and technology companies, we are committed to solving the biggest bottlenecks in scalable space access, starting with intelligent, reliable power.Job DutiesLead the design and validation of spacecraft power subsystems including isolated/non-isolated DC-DC converters, power regulation networks, and distribution unitsOwn development of battery systems, including charge control, protection circuitry, and health monitoringImplement MPPT (maximum power point tracking) techniques for solar array optimizationCreate detailed schematics and multilayer PCB layouts using Altium or similar ECAD toolsSupport bring-up, integration, and qualification of flight hardware including environmental and functional testingDrive analysis of power budgets, efficiency trade-offs, and system-level energy strategiesCollaborate closely with avionics, mechanical, and embedded software teams to ensure seamless power delivery across subsystemsApply design standards for space-readiness including thermal limits, launch vibration, and radiation toleranceQualificationsBS or MS in Electrical Engineering or related technical field3+ years of hands-on experience designing and testing power electronics or embedded power systemsSolid foundation in analog design, switch-mode power supplies (SMPS), and energy storage technologiesFamiliarity with simulation tools (LTspice, PLECS, etc.) and ECAD platforms (Altium, KiCAD, etc.)Demonstrated ability to debug board-level issues and support system integrationUnderstanding of power reliability in harsh environments including thermal extremes and radiationComfortable operating independently in a fast-moving, mission-driven hardware environmentPreferred ExperiencePrevious design experience with flight-ready power systems for CubeSats, microsats, or space-rated electronicsExperience working with modular spacecraft platforms or scalable satellite bus architecturesFamiliarity with lithium-ion battery chemistries and space-based charge control profilesExposure to government, dual-use, or national security-focused space programsPrior work in early-stage startups with small, agile engineering teamsWhy Join Us?Lead development of core flight hardware from day oneHelp shape the electrical and systems architecture of a new spacecraft platformCollaborate with experienced engineers solving some of space's hardest problemsOpportunity to grow with a high-upside pre-seed startup already working with active customersEquity in a growing space ventureStrong PTO policyMedical, dental, and vision coverageFlexible and collaborative work environmentSeniority levelSeniority levelMid-Senior levelEmployment typeEmployment typeFull-timeJob functionJob functionEngineering, Information Technology, and DesignIndustriesDefense and Space Manufacturing, Space Research and Technology, and Aviation and Aerospace Component ManufacturingReferrals increase your chances of interviewing at Approach Venture by 2xInferred from the description for this jobMedical insuranceVision insuranceGet notified when a new job is posted.Sign in to set job alerts for “Senior Electrical Engineer” roles.Senior Electrical Manufacturing EngineerSan Francisco, CA $201,025.00-$236,500.00 1 month agoSr Electrical Quality Engineer (Electromechanical)Alameda, CA $125,000.00-$175,000.00 1 month agoSenior/Staff Power Electronics Manufacturing EngineerSan Francisco, CA $144,500.00-$180,600.00 2 weeks agoSenior Electrical Engineer / Authority Having JurisdictionSan Leandro, CA $125,000.00-$175,000.00 2 weeks agoSan Francisco, CA $175,000.00-$220,000.00 7 months agoSan Francisco, CA $170,000.00-$210,000.00 2 weeks agoSan Leandro, CA $75,000.00-$175,000.00 3 weeks agoSan Mateo, CA $187,700.00-$281,500.00 2 weeks agoAlameda, CA $100,000.00-$130,000.00 6 days agoSenior Instrumentation and Controls EngineerRichmond, CA $130,000.00-$190,000.00 5 days agoSan Francisco, CA $140,000.00-$270,000.00 7 months agoAssociate/Senior Associate - Electrical EngineerSan Francisco, CA $180,000.00-$220,000.00 8 months agoRedwood City, CA $135,000.00-$175,000.00 2 weeks agoSan Francisco, CA $140,000.00-$170,000.00 8 months agoAlameda, CA $140,000.00-$170,000.00 5 days agoAlameda, CA $125,000.00-$200,000.00 1 month agoSan Francisco, CA $95,000.00-$105,000.00 35 minutes agoSouth San Francisco, CA $100,000.00-$125,000.00 2 weeks agoWe’re unlocking community knowledge in a new way.
