We are looking for a strong software engineer with a proven track record of delivering AI products, including hands‑on experience evaluating, deploying, and integrating AI solutions into real production systems.

Aerospace experience is not required – rather we look for smart, motivated, respectful, collaborative engineers who love solving problems and want to make an impact on a super inspiring mission. You will have full ownership of challenging problems, working with a team of enthusiastic engineers with diverse perspectives to design and produce solutions that enable the company to move towards our goals at a rapid pace. The success of the missions at the company depends on the software that you and your team produce.
