Job description

Level 3 Field Engineer

Senior On-Site & Remote Infrastructure Engineer

Full-Time • New York / New Jersey area • Field Services

About the Role

We need a senior field engineer who can walk into unfamiliar environments, diagnose complex issues, and own them through to resolution. As a senior (L3) escalation point, you handle our toughest issues and engage vendors when a problem needs to go further. This is a high-trust role for someone who thrives on variety and complexity, not routine. Most importantly you must work well with a team that helps each other and works closely together.

Responsibilities

Technical Escalation & Support

• Serve as a senior escalation point for issues unresolved by L1/L2 technicians – both remote and on-site.
• Troubleshoot and resolve advanced problems across servers, networks, endpoints, and liaise with software applications.
• Engage vendors when necessary; own the issue through to resolution regardless of path.
• Collaborate with the wider team. Reaching out, asking, and answering to get issues solved quickly.

Field & Infrastructure Work

• Lead and participate in networking deployments, hardware replacements, and production cutovers (in live environments).
• Deploy and support networking environments of all shapes and sizes, including non-standardized setups (across multiple vendors of switching, wireless, routing, and firewalls).
• Walk into unfamiliar client sites with minimal context and assess, prioritize, and resolve technical issues.
• Handle emergency deployments, infrastructure cutovers, and site relocations.

Network & Systems Work

• Assess client network environments during site walkthroughs. Identify switch consolidation opportunities, recommend equipment placement, (VLAN improvements,) and propose practical upgrades with confidence.
• Administer Windows Server environments, virtualization platforms, and cloud infrastructure.

Availability & Coverage

• Be available to provide weekend, holiday, and after-hours coverage for urgent incidents and escalations.
• This role involves occasional travel for emergency and on-site work, with trips typically lasting 1-5 days. Overnight travel averages 10–15% and may be required on short notice.

Mentorship & Documentation

• Mentor L1/L2 technicians; provide guidance on escalated issues and best practices.
• Maintain thorough, standardized documentation of solutions, client environments, (and processes).

Required Qualifications

Experience

• 7+ years in IT support, including at least 3 years in a Level 3 or senior engineer role.
• Prior MSP or multi-client environment experience strongly preferred.
• Hands‑on experience with server/workstation hardware, cabling, and on‑site troubleshooting.

Technical Skills

• Strong Windows Server administration experience (exposure to Mac & Linux a plus). Virtualization: Hyper‑V (vSphere).
• Microsoft 365, Azure, and Intune (for endpoint and identity management).
• Networking: Firewalls, VPNs, VLANs, DNS/DHCP, and best practices. Core networking fluency matters more than any single vendor platform – you should be able to log into a SonicWall, Fortinet, Meraki, or comparable device and understand it.
• Comfortable with PowerShell for routine administration.

Other Requirements

• Comfortable working independently in unfamiliar environments without step‑by‑step guidance.
• Available for last‑minute travel, weekends, late nights, holidays, and overtime.
• Based in the New York / New Jersey area (Connecticut considered) with reliable vehicle and a valid driver’s license.
• Real‑world experience setting up, managing, and troubleshooting firewalls, servers, and general networking.
• Experience with emergency site support, relocations, or infrastructure cutovers.
• A genuine team player who works well with others.

Preferred Qualifications

What Success Looks Like

• Can be dispatched on‑site with confidence that the work gets done right.
• Figure-it-out‑ability – given an unfamiliar problem, you work it through independently or by asking, retain what you learn, and pass it on to others.
• Moves at a good pace without sacrificing quality or documentation.
• Resourceful when documentation is sparse or systems are unfamiliar.
• Calm and level‑headed under pressure.
• Communicates clearly with clients and teammates.
• Dependable for after‑hours and emergency coverage without handholding.
• L1/L2 techs grow from working alongside you.

Not the Right Fit If You…

• Prefer a predictable 9–5 schedule.
• Need extensive documentation before starting work.
• Are uncomfortable working independently on unfamiliar systems.
• Are unavailable for emergencies, after‑hours, or weekend coverage.
• Prefer remote support over hands‑on field work.

Salary range

$75,000–$110,000 annually, commensurate with experience and qualifications.
