The responsibilities will include modifying existing designs, bench testing, flight testing, and troubleshooting our hybrid electric powertrain and electrical systems. You will be involved in the high-voltage power train, electrical systems, harnesses, and testing. This role requires a balance of high-level engineering and hands-on ability to execute tasks across multiple disciplines as we advance the future of middle-mile logistics.\nResponsibilities\nIron Bird Development: Take charge of the electrical layout, wiring, and assembly of the aircraft’s Iron Bird ground test platform. This skeletal replica of the aircraft’s avionics and power train serves as a non-flying ground test platform. Run tests and analyze data on flight-representative subsystems, wire harnesses, and actuators. \nPowertrain: Build, test, and iterate on the hybrid-electric powertrain architecture, including the turbine powerplant, generators, high-voltage motors and battery pack integrations.\nHigh Voltage and Power Distribution: Build, Test, and iterate on the high-voltage distribution network, ensuring strict safety isolation, grounding, EMI/EMC mitigation, and circuit protection. Systematically solve observed issues, propose and implement solutions in collaboration with our multidisciplinary team.\nHands-on Harnessing: Layout, build, and rework complex aerospace-grade wire harnesses. Select connectors, shielding, and routing paths optimized for SWaP-C.\n Test and Flight Validation: Define and implement electrical testing strategies. Perform comprehensive test plans, design and build test fixtures, conduct hardware-in-the-loop (HIL) testing, and support ground and flight test operations.\nCross Disciplinary Collaboration: Act as the primary point of contact for electrical considerations, collaborating with mechanical, software, flight test, and systems engineering to rapidly bridge gaps between hardware and software.\n Safety and Compliance: Ensure that system testing is conducted safely and implement risk mitigation strategies. Verify that electrical designs adhere to safety standards, participate in safety reviews, and maintain clear documentation to support FAA certification pathways.\nOur Ideal Candidate\nBachelor’s degree or higher in Electrical Engineering or a related field\n5+ years of professional engineering experience, ideally in a fast-paced startup, or small team environment\nProven track record with electric vehicles, eVTOL, or aerospace powertrain and high-voltage DC distribution development\nExtensive experience debugging and using lab equipment like oscilloscopes and spectrum analyzers\nProficiency in electrical CAD tools for schematic capture, layout, and wire harness design\nDemonstrated ability to self manage competing priorities, self-directed tasks, and solve ambiguous problems\nBonus Points For\nMaster’s degree in Electrical Engineering or a related field\n8+ years of experience in electrical systems design for autonomous systems or VTOL aircraft\nExperience with hybrid propulsion systems\nFamiliarity with aerospace certification frameworks or guidelines\nHands-on experience with flight testing and data analysis using Python or MATLAB\nWhat We Offer:\nCompetitive salary\nEquity ownership in a rapidly growing advanced aerospace company\nComprehensive medical benefits\n401(k) with company contribution + Roth IRA\nFree daily lunch provided onsite\nFlexible time-off policy\n3 months of paid parental leave\nEmployee assistance program with 24/7 support\nHigh-impact startup environment with significant ownership and autonomy\nOpportunities for rapid career growth and internal advancement\nYou’ll work with a motivated, kind, and highly skilled team\nYou'll help shape and define our company culture and values\nYou'll help build and scale a new category of aerospace / logistics
