Software Engineer I

York Space Systems is seeking a Full Stack Software Engineer who is passionate about building software that pushes the bounds of what's possible. Our software is a modern web-based application (React/TypeScript, C# .NET) with a microservice infrastructure (Docker, Kafka, REST) that operators use to monitor and control constellations of spacecraft across several active missions.

This is an early-career role designed for engineers who are eager to grow quickly in a technically demanding environment. You'll work alongside experienced engineers who will support your development through mentorship, code reviews, and collaborative design discussions. As you ramp up, you'll take on real feature work like implementing UI components, building backend logic, fixing bugs, and contributing to the same platform that operators use to manage active satellite missions. The problems we work on are complex, and you will be supported by your team and leadership to engage with and grow into that complexity over time.

Prior space-industry experience is not required.
