Software Engineer (Frontend)

• Muon seeks a Software Engineer to join our Mission Frontend team
• In this role you will build and ship features across our Mission Command platform, the consolidated frontend for mission operations, customer-facing tools, and internal workflows
• You’ll work in a modern TypeScript monorepo and contribute to establishing this platform as the canonical interface for managing constellations, scheduling contacts, and monitoring tasking at scale
• Day to day, you’ll own features end-to-end; from design through deployment and post-launch operational health, collaborating closely with the team on technical design, and shared foundations
• You’ll also be part of a team that treats AI-assisted coding tools (Claude Code, Copilot, and similar) as a core part of the workflow, applying the same rigor to AI-generated output as to human-authored code
• This is a high-impact role delivering reliable, high-performance, and accessible experiences that satellite operators and customers depend on every day
• Build and ship features across Muon Space’s unified web platform, delivering reliable, high-performance, and accessible experiences for satellite operators, customers, and internal users
• Own features end-to-end, from design and implementation through deployment, with appropriate test coverage, documentation, and post-launch monitoring
• Participate actively in code reviews and technical design discussions, contributing informed perspectives and helping raise the quality bar across the team
• Collaborate across backend and product teams to define requirements as needed
• Support operational health of the features you ship, responding to issues surfaced through observability tooling and iterating to improve reliability and performance
• Grow into an autonomous, trusted contributor who consistently ships high-quality work and helps establish the unified web platform as the canonical interface for Muon’s mission and operational needs
