Senior Software Engineer - Endpoint

The role

You will own the layer that makes TokenShift work, including per-agent harnesses, compression rules, and installation mechanics. You will build infrastructure for AI developer tooling that runs on developer machines.

What you will do

• Own the installation and enrollment mechanics including CLI flows, MDM scripts, and platform-specific packaging.
• Instrument and monitor endpoint behavior through the telemetry pipeline.
• Build and maintain a lab for automatic research and development of new capabilities and platforms by AI agents.
• Build and maintain agent harnesses to route network and shell commands through the TokenShift proxy.
• Develop and extend compression rules and strategies for new command types.
• Maintain correctness and resilience of the proxy layer.
• Collaborate with the research team to translate agent architectures into production-grade harnesses.

Required qualifications

• Solid understanding of Windows and Unix fundamentals: process model, shell execution, stdin/stdout/stderr, file permissions, and IPC.
• Deep familiarity with MDM deployment patterns (Jamf, Intune, JumpCloud, Ansible).
• Strong proficiency in Go.
• Experience building or maintaining CLI tools in production environments.
• Attention to correctness and edge cases.
• Ability to work across platforms (macOS and Linux) and understand their differences at the system level.

Nice to have

• TypeScript experience.
• Hands-on experience with AI coding agents (Cursor, Claude Code, Copilot CLI, Codex) as a user or developer.
• Experience with semantic compression, summarization, or output parsing.
