Senior Software Engineer, Endpoint Agent (MacOS)

Keeper Security is one of the fastest-growing cybersecurity software companies that protects thousands of organizations and millions of people in over 150 countries. They are seeking a Senior Software Engineer to help build and scale the MacOS endpoint agent for their Endpoint Privilege Manager solution, focusing on designing and implementing agent capabilities that enforce privilege policy in real time.

Responsibilities:

• Design, build, and maintain macOS agent components for EPM, including elevation workflows, policy enforcement, and audit logging
• Implement secure local policy evaluation and caching to support offline/online operation and consistent enforcement
• Build robust agent lifecycle capabilities including installation, upgrades, rollback safety, notarization/signing, and configuration management
• Integrate the agent with management-plane services and APIs for policy distribution, device identity, telemetry, and reporting
• Strengthen tamper resistance and abuse prevention, including hardening service/daemon behavior and agent configuration/update flows
• Improve diagnostics and observability (structured logs, health signals, performance profiling, crash handling) to support enterprise deployments
• Collaborate with QA Automation to improve test coverage and reliability across unit, integration and end-to-end test suites
• Participate in secure SDLC practices, threat modeling, code reviews, and on-call/incident response as needed

Requirements:

• 5+ years of professional software engineering experience delivering production software
• Strong experience building macOS-native software such as daemons/services, endpoint agents, system utilities, or security tooling
• Proficiency in one or more languages commonly used for macOS agent development (e.g., Swift/Objective-C, C/C++, Rust, Go)
• Solid understanding of macOS security and privilege models (process execution, entitlements, TCC/privacy controls, least privilege patterns)
• Experience with packaging and enterprise deployment patterns on macOS (pkg, signing, notarization, MDM distribution)
• Strong debugging skills for complex issues (concurrency, performance, stability, and root cause analysis)
• Experience building automated tests and working in CI/CD environments; strong engineering hygiene around reviews and documentation
• Strong communication skills and ability to partner cross-functionally with Product, QA and Security
• Experience with endpoint privilege management, EDR/EPP agents, device management, or identity/security products
• Familiarity with macOS platform security architecture (e.g., system extensions) and enterprise management workflows
• Experience designing policy engines (rules evaluation, precedence, auditability, explainability)
• Familiarity with secure update mechanisms, signing/notarization, and release hardening for endpoint software
• Exposure to IT admin and MSP workflows and macOS enterprise tooling (e.g., Jamf, Kandji, Intune for macOS)
• Exposure to secure SDLC practices and compliance-minded engineering (e.g., SOC 2, FedRAMP, NIST)
