Senior Software Engineer - Frontend
Job description
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by engineers and technologists with deep experience across commercial and defense technology, we were frustrated by the outdated and insecure technology America's service members are forced to rely on.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 Sr. Fullstack Engineer to join our team, building the next generation of mission planning and command and control software for space communications programs. This team is tasked with creating modern, resilient services and capabilities to service the US Government for the next decade and beyond.
As a Sr. Fullstack Engineer, you will lead the development of intuitive UI/UX and enhance backend services to support Sphinx's space vehicle mission planning platform, which is being leveraged by some of the most important space missions operated by the US Government. We're seeking an experienced engineer with strong front-end development skills AND backend programming fundamentals. You'll work as an individual contributor and a lead for more junior engineers.
What you will be focusing on:
- This is a fully remote role. All work must be completed in the United States. Occasional travel may be required, such as client visits, semiannual company gatherings, and other project related travel as needed may be required.
COMPENSATION
This role is between $160,000 - $185,000 base salary.
BENEFITS
Compensation includes competitive salary, meaningful equity ownership, profit sharing, employer 401(k) contribution, and 100% employer covered medical, dental, and vision insurance for you and your dependents.
