Engineering Manager, Frontend

Muon seeks an Engineering Manager to lead our Frontend team. This team builds and ships features across our Mission Command platform, the consolidated frontend for mission operations, customer-facing tools, and internal workflows. The team works in a modern TypeScript and is establishing this platform as the canonical interface for managing constellations, scheduling contacts, and monitoring satellite operations at scale.

The Frontend team is critical to the overall growth and success of Muon's product offerings. As the number of products and services delivered to customers expands, the reliable, high-performance, and accessible experiences this team delivers directly determine how effectively satellite operators and customers can accomplish their work every day. This manager will inherit a team of engineers, and will be responsible for both scaling that team to meet current demand and evolving it into a product-minded frontend organization that establishes the unified web platform as the canonical interface for Muon's mission and operational needs.

This position is hybrid and requires working on-site in our San Jose, CA office three days per week.
