Who We Are

Loft Orbital builds “shareable” satellites, providing a fast & simple path to orbit for organizations that require access to space. Powered by our hardware & software products, we operate satellites, fly customer payloads onboard, and handle entire missions from end to end - significantly reducing the lead-time and risk of a traditional space mission.

Our standard interface enables us to fly multiple customer payloads on the same satellite, with capabilities such as earth imagery, weather & climate /science data collection, IoT connectivity, in-orbit demonstrations, and national security missions. Our customers trust us to manage their space infrastructure, so they can focus on what matters most to them: operating their mission and collecting their data.

At Loft, you’ll be given the autonomy and ownership to solve significant challenges, but with a close-knit and supportive team at your back. We believe that diversity and community are the foundation of an open culture. We are committed to hiring the best people regardless of background and make their time at Loft the most fulfilling period of their career.

We value kind, supportive and team-oriented collaborators. It is also crucial for us that you are a problem solver and a great communicator. As our team is international, you will need strong English skills to better collaborate, easily communicate complex ideas and convey important messages.

With 4 satellites on-orbit and a wave of exciting missions launching soon, we are scaling up quickly across our offices in San Francisco, CA | Golden, CO | and Toulouse, France.

As an international company your resume will be reviewed by people across our offices so please attach a copy in English.
