Senior Frontend Software Engineer - Ground Software

York Space Systems was founded to radically improve spacecraft affordability and reliability, transforming, and enabling next- generation space mission operations worldwide. Today, York is one of the most innovative aerospace companies, specializing in end-to-end customer solutions and the rapid production of spacecraft platforms. York’s complete Space Segment Solution includes spacecraft production, payload integration, system integration & test, launch services, ground segment services, and mission operations, enabling customers to leverage York’s existing technology solutions to get to orbit rapidly and responsively. We’re looking to expand our team across the board.

We are looking for a Senior Frontend 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.

As a senior member of the team, you'll own the frontend experience end-to-end, from design system management to the real-time telemetry dashboards that satellite operators depend on in high-stakes environments. You'll partner closely with UI/UX, backend engineers, and operators to build interfaces that are fast, reliable, and intuitive under pressure, tackling difficult problems like:

• Visualizing live satellite state across a constellation
• Surfacing alerts during critical mission windows
• Designing workflows to transfer data between air-gapped environments
• Ensuring full UI functionality during the transfer of control between Mission Operation Centers

You'll also drive frontend best practices across the team and help junior engineers grow their craft.

Prior space-industry experience is not required.
