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by engineers and technologists with deep experience across commercial and defense technology, we were frustrated by the outdated and insecure technology America's service members are forced to rely on.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.
ABOUT THE ROLE
Sphinx is hiring a Backend Engineer to join our Space Communications team building a ground communications and data-transport platform for US government satellites. As a Backend Engineer you will lead the development of core platform services, designing and building technology to support the operations of a wide variety of US Government satellites. You'll work as both an individual contributor and a lead for more junior engineers.
We’re looking for a track record of the following:
- Experience working on multi-tenant services on public cloud platforms like AWS, Azure, or GCP
- Developing and consuming APIs and services as part of platform ecosystem
- 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
- The ability to communicate clearly
You might be a good fit if:
- You have 3-5+ years’ of progressively responsible software engineering experience
- You have extensive experience with Python, FastAPI, postgres, AWS, Docker, Kubernetes, Terraform
- You have 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
Nice to have:
- Prior experience working in space, satellite communications, or building ground systems.
