About Sphinx

Sphinx builds software to solve complex national security problems in Space. Founded by engineers and technologists with deep experience across commercial and defense technology, we were frustrated by the outdated and insecure technology America’s service members are forced to rely on. We’re here to do better.

We’re focused on building modern, scalable products with an emphasis on using open source technologies. Expect talented, motivated, and interesting colleagues who emphasize collaboration, transparency, and individual responsibility.

The Sphinx Space Communications team is a small, engineering‑focused team that prioritizes delivering quality products and learning from each other. The team is distributed across the US, with a strong culture that balances independence with collaboration.

Sphinx is hiring a Dev Ops Engineer to join our team building a cutting‑edge communications platform for US government satellites. We’re looking for an experienced Dev Ops Engineer to help take our build and deployment automation to the next level. As a Dev Ops Engineer you will help build the development and deployment infrastructure used by our Space Communications team, which provides infrastructure for a wide variety of US Government satellites.

As an early hire on a small team, you will have an outsized role in determining what we build and how we work.
