About The Role
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by engineers and technologists with deep experience across commercial and defense technology, we were frustrated by the outdated and insecure technology America's service members are forced to rely on.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.
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.
Responsibilities
What you will be focusing on:
- Building performant, secure, tested web applications with a focus on automation and security
- Designing, enhancing, and improving APIs between front-end and backend software services
- Leading the development of critical features, taking ownership of the entire development lifecycle from design to deployment
- Conducting thorough code reviews to maintain code quality, enforce best practices, and ensure code adheres to established standards
- Creating and translating design mockups into functional, visually appealing user interfaces using modern front-end frameworks (FastAPI, SQLAlchemy, PostgREST, Svelte, React, CesiumJS) and technologies like Python, Javascript, Typescript, CSS, and Kubernetes
- Advocating for improvements to product quality, security, and performance that have a particular impact on your team and others
- Supporting junior engineering talent with mentorship or technical guidance
Qualifications
You might be a good fit if you have:
- 5+ years of progressively responsible web development experience with modern software development approaches
- Extensive experience with JavaScript, HTML, CSS, TypeScript, web frameworks (React, Svelte), and concepts such as caching, authentication, and CSP
- You are a well-rounded engineer comfortable wearing multiple hats, such as a web designer, UX designer, and engineer
- You possess a strong understanding of backend code with experience integrating the front-end and the backend (and the willingness to fix the backend when it's needed)
- You are comfortable working with ambiguity and can self-direct your work while guiding others and supporting project leadership activities
- You understand the importance of, and you have the desire to own a technical problem end-to-end
- You've made enough mistakes and booked enough wins to know what not to build and what good looks like
- Excellent communication skills, working with end-users to design and build solutions to their needs, a habit of self-directed learning of new technologies, and the ability to learn quickly and adapt to a fast-paced environment
Bonus
Bonus points if you have the following:
- You have experience designing and developing intuitive user interfaces featuring real-time, 2D/3D geospatial visualizations
