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.

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

• 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.

• BS/MS in Computer Science, Engineering, or related field OR equivalent industry experience.
• Strong problem solving mindset with a focus on the end user while considering long term outcomes.
• 5+ years of software engineering experience, ideally with strongly-typed frontend languages such as Type Script or Flow.
• A passion for semantically correct, stable, clean code.
• Demonstrated experience contributing to complex web applications.
• Experience working in codebases with automated CI/CD pipelines and static analysis enforcement.
• Proficiency in code revision management within larger, fast-moving teams.

• Experience with AI assisted / agentic coding tools such as Codex or Claude Code.
• Experience working with SSR (server-side rendering), RSC (React server components), and isomorphic code.
• Experience working with 3d applications.
• Experience working with interactive mapping and/or geospatial data visualization.
• Experiencing working with large, cross-team monorepos.
• Experience with accessibility-focused component libraries such as React Aria or Radix UI.

• Have had exposure to the aerospace/space industry, satellite operations concepts, or mission-critical software environments.
• Experience authoring or maintaining CI/CD workflows (e.g., Git Hub Actions), containerized build/deploy pipelines (Docker, Helm), or automated dependency management tooling (e.g., Renovate, Dependabot).
