Senior Infrastructure & Security Engineer

About NuView: 

NuView IT is a security-first Managed Services Provider (MSP) and Managed Security Services Provider (MSSP) platform integrating founder-led IT services firms into a unified, AI-enabled leader. Our mission is to deliver premium, secure, and efficient IT & cybersecurity services to SMBs through a standardized, high-margin, and scalable operating model. NuView drives value through disciplined integration, recurring revenue growth, cross-selling of advanced security offerings, and operational excellence, targeting top-quartile MSP performance.

Job Description: 

The Senior Network/Cloud/Systems Engineer is a hands-on technical leader responsible for delivering secure, compliant, and reliable IT services to NuView clients. This role operates at the Tier 3 / escalation level, supporting complex environments, mentoring engineers, and ensuring consistent execution of NuView’s technical standards.

This position is delivery-focused, not managerial. The Senior Network/Cloud/Systems Engineer plays a critical role in solution execution, technical quality, client trust, and platform consistency, especially in regulated and security-sensitive environments.

Key Responsibilities:

Technical Delivery & Escalation Support

• Serve as a Tier 3 escalation point for network, cloud, and systems issues across NuView’s client base.
• Engineer and support network environments, including FortiGate firewalls, routing and switching, site-to-site and client VPN, SD-WAN, and wireless.
• Engineer and support cloud and identity environments, including Microsoft 365, Azure, Entra ID, Intune, and conditional access.
• Engineer and support core systems, including Windows Server, Active Directory, virtualization, and backup and recovery.
• Lead remediation and recovery efforts during incidents, outages, and security events.
• Own complex technical issues through resolution, ensuring root cause is identified, documented, and remediated whenever possible to prevent recurrence.

Security & Compliance Execution

• Implement and maintain controls aligned with frameworks such as HIPAA, NIST 800-171, CMMC, PCI-DSS, and SOC 2 (as applicable to client environments).
• Support vulnerability remediation, hardening, MFA deployment, backup validation, and incident response activities.
• Work with security leadership and vCISO resources to execute compliance-driven technical requirements.

Solution Implementation & Projects

• Deliver client projects including migrations, security enhancements, cloud deployments, and infrastructure upgrades.
• Execute projects according to NuView standards, timelines, and documentation requirements.
• Participate in pre-project technical discovery and post-project validation.
• Identify technical debt, security gaps, lifecycle risks, and infrastructure improvement opportunities that can improve client outcomes while supporting recurring revenue and project growth.

HaloPSA & Operational Discipline

• Maintain exemplary ticket hygiene and documentation within HaloPSA.
• Accurately log time, work performed, configuration changes, and outcomes for all tickets and projects.
• Adhere to “no ticket, no work” standards and support continuous process improvement.

Platform Standardization & Knowledge Sharing

• Contribute to standardized configurations, runbooks, SOPs, and internal documentation.
• Champion NuView platform standards by reducing unnecessary client-to-client variation and promoting approved technologies, configurations, security controls, and operational practices.
• Identify recurring issues or inefficiencies and propose improvements to tooling or process.
• Act as a technical mentor to Tier 1 and Tier 2 engineers by coaching troubleshooting methodology, documentation quality, client communication, and sound technical decision-making.

Client Trust & Professionalism

• Act as a trusted technical advisor to clients during escalations, projects, and security-related discussions.
• Communicate clearly and professionally and stay calm in high-pressure situations.
• Represent NuView’s security-first mindset and commitment to excellence in every engagement.

Analytical Ability & Business Judgment

• Carry a deep, intrinsic focus on client outcomes. NuView is client first, and the result the client needs matters more than anything else.
• Quickly assess complex, ambiguous problems and drive to root cause rather than treating symptoms.
• Find practical solutions under real constraints, weighing the right fix against time, budget, and client impact.
• Translate technical decisions into business terms: cost, risk, and downtime.
• Recognize when a recurring issue signals a process or design problem instead of a one-off.
• Understand the relationship between technical decisions and business outcomes, balancing risk, security, client experience, operational efficiency, and profitability.

Success in the Role

A successful Senior Network/Cloud/Systems Engineer will:

• Serve as a trusted Tier 3 escalation resource across the NuView platform.
• Drive root-cause analysis and reduce repeat incidents through permanent remediation.
• Improve documentation quality, technical consistency, and operational discipline
• Contribute to platform standardization initiatives and security-first best practices.
• Mentor and elevate the technical capabilities of other engineers.
• Identify opportunities to reduce technical debt and improve client outcomes.
• Consistently deliver projects and escalations that strengthen client trust and satisfactions in every engagement.

Requirements

• 5+ years in IT infrastructure, systems engineering, or MSP/MSSP environments
• Proven experience supporting security-conscious or regulated clients
• Network: FortiGate, routing and switching, VPN, SD-WAN, wireless, with Cloudflare Zero Trust a plus
• Cloud and identity: Microsoft 365, Azure, Entra ID, Intune, conditional access
• Systems: Windows Server, Active Directory, virtualization, endpoint management, backup and recovery
• Security tooling exposure across an MSSP stack such as CrowdStrike, ThreatLocker, and Cisco Duo
• Experience in a PSA-driven service organization; HaloPSA strongly preferred
• Ability to balance speed, security, and quality in client-facing work.
• Demonstrated ability to independently manage complex technical workstreams with minimal supervision while maintaining strong communication and accountability.
