Senior Site Reliability Engineer

Wanna join the adventure?

Loft Orbital is revolutionizing access to space by building reliable, shareable satellites that drastically reduce the time and complexity traditionally required to get to orbit. We operate satellites, fly customer payloads, and handle entire missions from end-to-end. We’re a close-knit team of space enthusiasts, software experts, and cutting-edge technologists, all working together to make space simple for our customers.

Loft: Space Made Simple. 

Founded in 2017, Loft provides governments, companies, and research institutions with a fast, reliable, and flexible way to deploy missions in orbit. 

We integrate, launch, and operate spacecraft, offering end-to-end missions as a service across Earth observation, IoT connectivity, in-orbit demonstrations, national security missions, and more. Leveraging our existing space infrastructure and an extensive inventory of satellite buses, Loft is reducing years-long integration and launch timelines to months. With more than 25 missions flown, Loft’s flight heritage and proven technologies enable customers to focus on their mission objectives. 

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.
