We apply aerospace engineering and quality standards across our products, delivering high performance, reliability, and efficiency for the most demanding operating environments. Astro Mechanica is backed by leading venture and strategic investors, including Andreessen Horowitz (a16z), Giant Step Capital, United Airlines Ventures, and Voyager Ventures. ## WHO WE ARE: We’re a team of passionate engineers dedicated to advancing aerospace. We’re generalists with specialist depth, united by a flat structure and a shared obsession with building things that work well. We move fast, stay pragmatic, and let engineering excellence speak louder than hierarchy. ## WHO YOU ARE: Astro Mechanica is looking for a Senior Electrical Engineer focused on power systems development to join our growing team. 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. ## WHAT YOU’LL DO: - 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 ## WHAT WE’RE LOOKING FOR: - 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 ## PERKS & BENEFITS: - 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 ## ADDITIONAL INFORMATION: 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. ## About Astro Mechanica ## Company Overview - **One-liner**: Astro Mechanica is building the world’s first turboelectric adaptive jet engine (Duality) that achieves high efficiency across both subsonic and supersonic speeds, aiming to democratize high-speed flight. - **Entity Type**: Private (Venture-backed; latest round: Series A-II / Venture Round in September 2025) - **Headquarters**: San Francisco, California, United States - **Founded**: 2021 - **Founders**: Ian Brooke (CEO & Founder) ## Core Business - **Primary industries**: Aerospace, aviation propulsion, defense systems - **Target customers**: US government (military and defense applications), commercial aviation (long-term), cargo/logistics - **Mission/purpose**: “Democratize high-speed flight by making supersonic travel flexible, accessible, and sustainable” – developing rapid, on-demand, point-to-point global mobility. ## Products & Services - **Duality™ Propulsion System**: A proprietary dual-use turboelectric adaptive jet engine designed to be efficient at all speeds from subsonic to supersonic. Currently in development and expected to begin altitude testing in 2027 on a dedicated testbed aircraft. - **Airframe & Flight Systems**: Vertically integrated design of airframes and flight control systems optimized for the Duality engine, with near-term focus on government contracts. ## Market Standing - **Valuation/Market Cap**: Not publicly disclosed - **Key Metric**: Total funding raised – **$54.7 million** as of the latest venture round in September 2025 (LinkedIn data; earlier reports by CBInsights indicated $27.6 million, likely reflecting a prior round) - **Notable Investors/Partners**: United Airlines Ventures (lead investor in latest round), Andreessen Horowitz, Giant Step Capital, Y Combinator (seed) - **Growth Signals**: Headcount grew **228.6% year-over-year** to ~35 employees; **36 active job postings** as of mid-2025; rapid hiring across engineering, manufacturing, and leadership roles; moving toward engine flight test in 2027. ## Competitive Advantages - **Unique engine architecture**: The turboelectric adaptive design allows a single engine to operate efficiently from subsonic to supersonic regimes, removing the need for afterburners or separate engines. - **Vertical integration**: In-house engine, airframe, and flight systems development enables tight optimization and rapid iteration. - **Flat engineering culture**: Described as “generalists with specialist depth” and a flat structure that accelerates decision-making and innovation. ## Strategic Focus - **Near-term**: Engine altitude testing (scheduled for 2027) and securing US government contracts for high-speed systems. - **Long-term**: Develop a full aircraft platform and operational model for economically viable supersonic commercial travel. ## Why Work Here - **Culture**: Emphasis on engineering excellence, pragmatism, and moving fast. Flat hierarchy where “engineering speaks louder than hierarchy.” - **Work policy**: Hybrid environment – most roles are based in San Francisco with a mix of in-office and remote collaboration. The majority of job listings specify “In-Office” at the HQ. - **Notable perks**: Not explicitly listed, but the company offers equity (typical for startups) and the opportunity to work on groundbreaking aerospace technology from concept to flight. - **Engineering focus**: Strong technical team with talent from SpaceX, Relativity Space, Boom Supersonic, Lockheed Martin, and Astra. Active hiring in propulsion, flight software, GNC, test engineering, and manufacturing. ## Sources 1. [astromecha.co](https://www.astromecha.co/) 2.
