You will be working with an extraordinary team to enable Astro Mechanica’s ground power product, which greatly accelerates the company’s ability to develop its ambitious aircraft product. In this role, you will be responsible for the medium voltage electrical system repurposing and adapting aircraft engines towards ground power generation. This is a hands-on, high-ownership where you will set the architecture, run the studies, specify the equipment, lead validation and commissioning, and be the technical authority on electrical safety. You will work closely with mechanical, controls, and manufacturing teams and represent the product with customers, utilities, and certification bodies. If you want to build a real power product rather than a slice of one, this role is for you.
Translate product requirements into electrical specifications, one-line diagrams, schematics, and BOMs
Own the electrical architecture and design of the plant including transformers, switchgear, cabling, protection, and grounding
Perform and review power system studies- load flow, short-circuit, protection coordination, arc flash, grounding, harmonics, and transient analysis
Ensure compliance with NEC, IEEE, IEC, UL, NFPA 70E, and utility interconnection requirements; own electrical safety and certification for the product
Mentor engineers, review designs, and serve as the technical interface to customers, utilities, and suppliers
BS, MS, or PhD with a focus on power electronics
5+ years of experience designing, building, testing, and shipping electrical power systems
Deep experience with medium-voltage systems (1–38 kV): generators, transformers, switchgear, protective relays, and paralleling/grid-interconnect schemes
Strong command of power system analysis (symmetrical components, fault calculations, protection coordination, arc flash) and proficiency in ETAP, SKM, or EasyPower
Working knowledge of applicable codes and standards (NEC, IEEE, IEC, UL, NFPA 70E) and experience taking a product through certification
Hands-on field experience commissioning and troubleshooting MV equipment and generator control systems
Track record of owning a complex electrical product from concept through production with cross-functional teams
Familiarity with power electronics (inverters, rectifiers, excitation systems) and controls integration (SCADA, PLC, communication protocols) is a plus
Comprehensive medical, dental, and vision insurance, including Flexible Spending Accounts (FSA)
401(k) program and transparent stock option plan
Self-managed and flexible time-off policy, including PTO, paid holidays, and sick time
Flexible work environment
At Astro Mechanica, we highly value in-office work to foster collaboration and strengthen our company culture. We consider working in the office five days a week an essential part of the employee's role.
Astro Mechanica is an equal opportunity employer. We proudly recruit and hire a diverse workforce and are committed to creating an inclusive environment for all employees.
