Full Job Description

Senior Systems Administrator / Infrastructure Architect (MSP – 10+ Years)

Location & Role Type

Location: Columbus, OH (Primarily in-office with limited WFH flexibility)

Type: Full-Time

Industry: Managed IT Services (MSP / MSSP)

About the Role

Kloud9 IT is seeking a Senior Systems Administrator with architect-level experience to help design, standardize, and support infrastructure across multiple client environments. This role is intended for a highly experienced professional (10+ years) who has worked extensively in MSP environments and is comfortable making architectural decisions, leading complex projects, and serving as the highest technical escalation point.

This position blends hands-on engineering with technical leadership. You will influence how environments are built, secured, documented, and maintained—while remaining directly involved in execution.

Core Responsibilities

Act as a senior technical authority and final escalation point for complex infrastructure issues

Design, implement, and maintain scalable, secure client environments

Own architecture and long-term health of Microsoft 365, Windows Server, and identity platforms

Architect and support network infrastructure including firewalls, switching, VLANs, routing, and site-to-site VPNs

Lead high-impact infrastructure initiatives such as Microsoft 365 migrations and modernization projects

Ensure environments align with security, compliance, and best-practice frameworks

Partner with security, service delivery, and project teams to align technical decisions with business and compliance requirements

Produce and maintain high-quality technical documentation and standards

Provide mentorship and technical guidance to other engineers

Communicate confidently and professionally with client stakeholders

Required Experience & Qualifications

10+ years of professional IT experience

Extensive MSP experience supporting multiple client environments

Advanced expertise in Microsoft Windows Server, Microsoft 365, Active Directory / Entra ID, and network design

Proven ability to architect solutions—not just support existing systems

Strong understanding of security fundamentals (MFA, backups, least privilege, endpoint protection)

Excellent documentation, prioritization, and decision-making skills

Preferred / Strong Plus Experience

Experience with CMMC, NIST 800-171, or similar security frameworks

Background supporting regulated or compliance-driven organizations

Experience defining technical standards and best practices

Familiarity with MSP tools (RMM, PSA, documentation platforms)

Relevant Microsoft, networking, or security certifications

Why Kloud9 IT

Kloud9 IT supports organizations that require reliability, security, and compliance. We value experienced engineers who think strategically, execute cleanly, and raise the technical bar for the entire organization.
