Senior Executive Assistant to the CTO

Inversion builds advanced reentry systems to deliver next-generation capabilities from space.

Our mission is to make Earth radically more accessible by turning Low-Earth Orbit into an on-demand logistics domain. We see space not as a destination, but as a platform — one that unlocks unprecedented speed and global reach.

Our spacecraft are designed to deliver payloads anywhere on Earth in under an hour, operating through extreme reentry conditions and landing with high precision. These systems open the door to new ways of testing, delivering, and operating at hypersonic speeds.

Inherently dual-use, our technology is built to meet urgent national security needs while laying the groundwork for future commercial applications. Backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, and working with partners such as the U.S. Space Force and NASA, Inversion is pushing the boundaries of what’s possible in space-based defense and logistics.

We are seeking a highly experienced, proactive Senior Executive Assistant to support our executive leadership team. This role goes far beyond calendar management—you will act as a strategic partner, operator, and force multiplier for leadership, helping drive efficiency, organization, and execution across the company. This role reports directly to the Inversion CTO.

You thrive in fast-paced, ambiguous environments, anticipate needs before they arise, and bring structure to chaos. You are equally comfortable coordinating board meetings, managing sensitive information, and jumping in to solve operational problems on the fly.

• 5+ years of experience supporting C-level executives (preferably in a startup or high-growth environment)
• Experience in aerospace, defense, hardware, or deep tech environments
• Proven ability to manage competing priorities with speed and accuracy
• Exceptional organizational skills and attention to detail
• Strong written and verbal communication skills
• High level of discretion
