    • You can demonstrate in-depth knowledge of at least one commercial cloud platform and its associated services

    • You’ve made enough mistakes and booked enough wins to know what not to build and know what good looks like
Sphinx builds software to solve complex national security problems for America and its allies. 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by engineers and technologists with deep experience across commercial and defense technology, we were frustrated by the outdated and insecure technology America's service members are forced to rely on.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 base compensation range for this position is 180-200k/year, and includes meaningful equity ownership, profit sharing, employer 401(k) contribution, and 100% employer covered medical, dental, and vision insurance for you and your dependents. We work across time zones and are very accommodating of flexible schedules.

Eligibility: The position is only open to US Citizens. This is a full time, remote (anywhere in the US) position.
