Electrical Engineer, Circuit Design & Power Electronics

Job description: Electrical Engineer, Circuit Design & Power ElectronicsLos Angeles, CA | Full-Time | 100% On-Site | $150K-$220K base + early-employee equityJoin a fast-moving, venture-backed defense technology startup building high-performance flight hardware. You will own the power and actuator drive electronics that fly on the company's vehicles. Avionics sits on the critical path for every flight test, so your speed directly sets the pace of the program.What You'll DoDesign power distribution and conversion systems, including battery management, power regulation, and protection circuitsOwn actuator drive electronics for the fin control actuation system: power stage, current sensing, motor commutation, position-interface front end, and motor-bus partitioningCreate schematics, PCB layouts, and bring-up procedures for mission-critical analog and digital avionicsLead EMI/EMC design and validation, including power integrity, grounding, and mitigation strategiesPartner with embedded software, systems, and controls engineers to integrate and tune hardware on the benchBuild test infrastructure and validation procedures, and handle debugging, integration, and environmental testingHelp define scalable electrical architecture standards for high-rate manufacturingTech StackAltium/KiCad, schematic capture, SPICE, power electronics, BLDC/PMSM motor drives, gate drivers, current sensing, BMS, EMI/EMC testing, oscilloscopes and lab equipment, FPGA interfaces, embedded systemsWork SetupFully on-site in Los Angeles, CA. Remote work is not available. Monthly weekend travel for test events and supplier visits. Qualifications: Must-Haves5+ years in circuit design and power electronicsPower systems experience in demanding hardware environments (aerospace, defense, automotive, robotics, or similar)Strong PCB design and layout with a system-level EMC approach (grounding, shielding, filtering, signal and power integrity)Hands-on lab experience debugging hardware and bringing up boardsProven ability to take designs from schematic to layout to integration and testExperience in a rapid development, 0-to-1 environmentDaily use of frontier AI tools (Claude, Cursor, etc.) in your workflowBS in Electrical Engineering or related fieldU.S. Citizen or Green Card holder (no visa sponsorship)Able to work fully on-site in Los Angeles, plus monthly weekend travelNice-to-HavesMotor drive design (BLDC/PMSM power stages, gate driver selection, current sensing topologies, EMI mitigation on high-current buses)FPGA interface experienceQualifying hardware to DO-160 or similar environmental standardsBackground in defense, automotive/racing, robotics, EV, or high-performance mobility Why is This a Great Opportunity: Real impact: Ground floor at a well-funded startup tackling a genuine national security problemVisible work: Your hardware flies every couple of weeksNo waiting: Avionics drives the schedule, so your velocity drives the companyOwnership: Engineers own design, build, and test end to end with minimal bureaucracyStrong comp: Competitive base ($150K-$220K) plus meaningful early-employee equityGrowth: Team is scaling quickly, with significant hiring planned over the next 6-12 monthsSalary Type : Annual SalarySalary Min : $ 150000Salary Max : $ 220000Currency Type : USDNigel
