Flight Software Engineer

In Orbit was founded to enable large-scale orbital research and manufacturing. Today, we are developing the next-generation of spacecraft for on-orbit operations and the return of cargo from space back down to Earth. To accomplish this, we are looking for an engineer eager to join a fast-paced team developing space services for a new orbital economy.

As a Flight Software engineer at In Orbit, your work will be critical to lead our team to success. You will be responsible for the design, test, and validation of the spacecraft flight software as well as supporting decisions to improve the on-orbit operations of complex spacecraft.
