Senior Propulsion Development Engineer

Astro Mechanica is a vertically integrated aerospace company developing a scalable technology platform to power critical infrastructure, mission operations, and the future of flight. 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.

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.

Astro Mechanica is looking for a Senior Propulsion Development Engineer to join our growing team. The ideal candidate is someone who has a deep-seated understanding of complex system dynamics, and can take full ownership of hardware testing from concept to production. Your work at Astro Mechanica will have a direct impact on the configuration and performance of the turboelectric adaptive jet engine.

In this role, your mission will be to shepherd our innovative jet engine and subsystems hardware from early prototype through flight qualification, vehicle integration, and aircraft flight. You will have the firsthand responsibility that every new design is rigorously tested to ensure quality and performance metrics are met prior to aircraft integration before leaving the ground. You embody the test-like-you-fly philosophy.
