Job Title:
Senior Endpoint Engineer (Tier 3 Desktop Specialist)

Location:
Primarily Remote (with occasional on-site visits)

Overview:
We are seeking a highly experienced and proactive Senior Endpoint Engineer to elevate our end-user computing environment. This role goes beyond break/fix support—it's about creating a consistent, reliable, and secure experience across all endpoints. You will own the integration of desktops, laptops, mobile devices, and related systems, ensuring issues are solved at scale, not just at the individual level.

Key Responsibilities:

• Serve as the Tier 3 escalation point for complex desktop issues across Windows, macOS, and iOS environments.
• Analyze root causes of recurring problems and implement fleet-wide solutions to prevent future incidents.
• Design and enforce standards for endpoint configuration, security, and performance to deliver a consistent user experience.
• Collaborate with network, security, and engineering teams to identify and resolve systemic issues (e.g., VPN performance, network stack bottlenecks).
• Evaluate and recommend hardware and software solutions, including guiding decisions on device procurement (Windows vs. Mac, monitor quality, etc.).
• Act as a trusted advisor to leadership, articulating technical challenges and presenting actionable solutions.
• Occasionally visit offices to assess real-world user experiences, troubleshoot environmental issues, and build relationships with stakeholders.
• Stay current with emerging technologies and leverage tools (including AI) to optimize troubleshooting and system design.

Required Qualifications:

• 7+ years of experience in end-user computing, desktop engineering, or endpoint management.
• Deep expertise in Windows environments (Lenovo laptops), with working knowledge of macOS and iOS.
• Strong understanding of networking fundamentals (IP addressing, VPNs, network stack troubleshooting).
• Familiarity with information security principles and systems engineering concepts.
• Proven ability to diagnose complex technical issues and implement scalable solutions.
• Excellent communication skills with the confidence to challenge assumptions and advocate for improvements.

Preferred Qualifications:

• Experience introducing macOS into enterprise environments.
• Knowledge of Cisco VPN and alternative remote access solutions.
• Exposure to program management and procurement processes.
• Ability to leverage AI tools for research and troubleshooting.

Work Style & Growth:

• Self-driven and proactive—able to identify problems and take initiative without waiting for direction.
• Comfortable working remotely but willing to visit offices as needed to engage with users and validate solutions.
• Opportunity for career growth into leadership and option for conversion to full-time employee after 6 month contract period of evaluation.
