📋 Description

• Own the macOS agent end-to-end • Architect and maintain privileged system services, inter-process communication, and robust self-updating mechanisms across non-administrated endpoints • Implement TLS interception and certificate trust chains on macOS • Resolve system proxy configuration conflicts alongside endpoint security tools, VPNs, and cloud proxies • Build native interception capabilities for AI developer tools to monitor and apply data-loss policies • Enforce fail-open architecture so local failures do not degrade network connectivity or access to corporate assets • Analyze customer logs and clean-state Mac reproductions to identify root causes and ship permanent fixes • Own product fixes for conflicts with other endpoint security products • Serve as principal technical authority for macOS engineering decisions across R&D

🎯 Requirements

• 5+ years of systems-level software development • 3+ years delivering production macOS software using Swift and Objective-C • Deep expertise in macOS platform internals, including launchd, XPC, code signing, notarization, packaging, privileged operations, and debugging complex runtime behavior • Solid grounding in networking fundamentals, including system proxies, TLS, certificate trust, and application-to-internet connections • Hands-on proficiency with modern AI development tools such as Claude Code or Cursor • Critical, verification-first approach to AI-generated code • Clear technical communication skills • Experience resolving critical technical issues alongside field engineers and enterprise IT teams • A CS degree or equivalent practical engineering background

🏖️ Benefits

• Building a native macOS platform rather than maintaining a ported Windows client • Full technical ownership over privileged services, trust chains, proxy configuration, and network components • Engineering culture enforcing strict "fail open" reliability • Root-cause product fixes rather than customer-side exclusions or temporary workarounds
