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 seeking a Power Electronics Controls Engineer to join our growing team. The ideal candidate is a controls engineer at heart who is excited to own the control of the power electronics that drive our propulsion: an 800-volt system delivering 1 megawatt of electrical power to the motors on our Gen 5 engine. You will bring that same controls expertise to our ground power systems, where large turbines and generators must be governed and kept in sync. You will work on a small, tight team alongside a mechanical engineer focused on the liquid-cooled inverter enclosure and an electrical engineer focused on the inverter hardware. Your work at Astro Mechanica will have a direct impact on the configuration and performance of our engine. ## WHAT YOU’LL DO: - Design, implement, and tune control systems for the inverters that drive the motors on our 800 V, 1 MW propulsion system - Develop controls for related power electronics, including DC-DC converters and motor controllers - Own bus control and governor design for our electrical systems - Support ground power by synchronizing and governing coupled systems, such as a 13 MW turbine and generator or a connection to grid power - Take systems from concept through hardware, validating control performance on real equipment - Work closely with mechanical, electrical, and propulsion engineers to bring the inverter from design through test ## WHAT WE’RE LOOKING FOR: - Bachelor’s degree in Electrical Engineering or a related field and 5+ years of experience in power electronics controls - Hands-on experience designing controls for power electronic systems, such as DC-DC converters, motor controllers, or inverters - Proven track record of building one of these systems, not just modeling or analyzing it - Working knowledge of motor control, including Field Oriented Control (FOC) and related techniques - Experience with three-phase electrical systems and machines, such as permanent magnet motors - Experience with high-voltage, high-power-density systems, such as EV traction or eVTOL propulsion - Inverter design experience is a plus - Experience synchronizing and governing coupled, complex power systems, such as multiple inverters, or turbines and generators for bus-tied or grid-tied power, 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.
