We are seeking a macOS Sr. Endpoint Engineer to provide Tier 3 support and lead the design, configuration, and lifecycle management of enterprise endpoints. This role is responsible for delivering secure, scalable, and high-performing endpoint solutions across macOS, Windows, and mobile environments, while improving overall user experience and operational efficiency.

This is a senior-level engineering role focused on building, standardizing, and enhancing endpoint environments—not a traditional support role.

Key Responsibilities

• Lead the design, implementation, and management of endpoint solutions, including workstation updates, mobile device security policies, and application configurations
• Serve as a subject matter expert for endpoint management platforms such as JAMF, Intune, SCCM, and Citrix
• Own and enhance macOS endpoint environments, including policy creation, configuration profiles, and lifecycle management
• Manage mobile device environments, including MDM and MAM solutions for both corporate-owned and BYOD devices
• Oversee deployment of security patches, updates, and endpoint protection solutions to ensure compliance and system integrity
• Manage the full lifecycle of endpoint hardware and software, including imaging, driver updates, BIOS/firmware updates, and refresh strategies
• Develop and maintain endpoint build standards, deployment procedures, and configuration baselines
• Lead cross-functional initiatives related to endpoint security, software packaging, and device management
• Support enterprise-wide deployment of next-generation technologies, including virtual desktop environments (VDI), macOS, Windows, and mobile platforms
• Define and enforce endpoint hardware standards and lifecycle management processes
• Use data and operational metrics to monitor performance, identify trends, and provide insights to leadership
• Drive continuous improvement of endpoint engineering services in partnership with infrastructure, operations, and security teams
• Train and enable support teams by improving documentation, reducing escalations, and building internal knowledge
• Create and maintain technical documentation, including knowledge base articles, standards, and procedures

Required Qualifications

• 5–7+ years of experience supporting and engineering endpoint environments in enterprise settings
• Strong hands-on experience with macOS and Windows environments
• Proven experience owning and building macOS environments using JAMF (not just supporting existing setups)
• Hands-on experience with Intune, including MDM/MAM for mobile device management
• Advanced expertise in Active Directory, including Group Policy, DNS, replication, and OU design
• Deep understanding of Windows registry, permissions, macOS preferences, and driver management
• Experience with SCCM and hybrid Azure Active Directory environments
• Strong scripting and automation experience using PowerShell
• Experience with application packaging and deployment (e.g., Microsoft 365, OneDrive)
• Knowledge of endpoint security, encryption, and cloud-based endpoint management
• Experience supporting virtual desktop environments (e.g., VMware vSphere, Citrix)
• Strong troubleshooting skills across LAN/WAN environments and remote endpoints
• Experience managing deployments, test plans, pilot groups, and release processes
• Strong communication skills with the ability to support high-touch users and explain technical concepts clearly

Preferred Qualifications

• Bachelor’s degree in a related field
• Experience with endpoint modernization and cloud-first device strategies
• Familiarity with emerging endpoint and security technologies
• Experience supporting developer environments (e.g., macOS-based tooling)
• Background in high-growth or technology-driven environments

Key Characteristics for Success

• Strong ownership mindset with the ability to build and improve systems from the ground up
• Effective communicator who can interact with both technical teams and end users
• Collaborative approach with the ability to work across infrastructure, security, and support teams
• Passion for documentation, standardization, and continuous improvement
• Ability to mentor and upskill support teams to reduce dependency and improve efficiency
