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/Type Script, 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. Y ou’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 :

• V isualizing live satellite state across a constellation
• S urfacing alerts during critical mission windows
• Designing workflows to transfer data between air‑gap 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.
