Principal Software Engineer (GTMO/Mesh)

• Owning features across the full stack - React frontends, backend APIs, cloud infrastructure - from design through production
• Responding to production incidents and shipping fixes
• Building and improving core platform capabilities: AI agents, orchestration workflows, microapp infrastructure, LLM integrations
• Developing SDKs and tooling for engineers who build on top of Mesh
• Championing quality and reliability - tests, coverage, habits that prevent regressions
• Collaborating across teams and supporting users directly through our Slack support channels
• Mentoring engineers through code reviews and technical guidance

Why Mesh:

• Small team, real impact - your contributions are visible and your opinions carry weight
• We use AI tools heavily in our own workflow - Claude Code, AI-assisted code review, LLM-powered automation
• Distributed systems, LLM reliability, workflow orchestration, real-time integrations - the problems are hard and varied
• We move fast and we’re getting smarter about how we do it
