Principal Backend Engineer

Sphinx is hiring a Principal Backend Engineer to join our team working with the US Space Force to build a cutting edge communications platform for US government satellites. As a Principal Backend Engineer, you will own the architecture and development of core platform services, designing and building technology to support the operations of a wide variety of government satellites. You will work both as an individual contributor and a lead for more junior engineers.

We're looking for a track record of the following:

• Defining architectures and building services on public cloud platforms like AWS, Azure, or GCP

• Working with a team to develop and operate APIs and services as part of a platform

• Developing with an emphasis on automation and security

• Willingness to own a technical problem end-to-end

• A habit of self-directed learning of new technologies

• The ability to work well with a team and a history of technical leadership and mentorship

• The ability to communicate clearly

You might be a good fit if

• You have 7 years of software engineering experience with progressively increasing responsibilities

• You have several years of experience architecting and building APIs and backend services

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

• Are comfortable working with some ambiguity and able to self-direct your work

• 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by engineers and technologists with deep experience across commercial and defense technology, we were frustrated by the outdated and insecure technology America's service members are forced to rely on.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.
