York Spaces SystemsGreenwood Village, CO
Hybrid

About The Position

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, and 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.
