Msp Network Engineer Jobs in Reston, VA (NOW HIRING)

cyDaptiv Solutions is hiring an IT Systems Engineer to support our Microsoft 365 environment and our Innovations Lab.

This is a hands-on, collaborative engineering role - not a help desk position. A managed service provider handles day-to-day support and routine Microsoft 365 administration, and a remote lab administrator leads our cloud and lab infrastructure. You are the onsite engineer who partners with both: engineering advanced tenant configuration, providing hands-on lab support, and using AI tools to automate and document the work. Expect roughly 60% lab and infrastructure support and 40% Microsoft 365 engineering, automation, and compliance.

• Serve as the onsite hands for the lab: racking, cabling, imaging, hardware installation, network segmentation, and out-of-band management.
• Build and maintain on-premises virtualization (vSphere, Hyper-V, or Proxmox), physical servers, switching, and firewalls.
• Stand up and tear down cyber range, demonstration, and proof-of-concept environments for capability development, customer demos, and proposal efforts.
• Support cloud infrastructure (AWS and Azure) alongside the lab administrator - networking, identity, and cost governance.
• Contribute to repeatable, version-controlled environments using infrastructure as code (Terraform, Bicep, or Ansible).
• Keep the lab isolated from production and free of CUI; maintain asset inventory, lifecycle, and secure disposal.

• Serve as internal technical authority for our Microsoft 365 tenant (E5 with Enterprise Mobility + Security), working alongside - not replacing - our MSP.
• Engineer configurations outside the MSP's scope: Entra ID Conditional Access, phishing-resistant MFA, PIM, app registrations, and SSO integrations.
• Design and maintain Intune configuration and compliance policies, Autopilot enrollment, app deployment, and update rings.
• Tune Microsoft Defender and Purview (sensitivity labels, DLP, retention); govern SharePoint, Teams, and external sharing for a CUI environment.
• Coordinate escalations with the MSP and Microsoft support on tenant-level issues.

• Use AI tools daily - Claude (including Claude Cowork and Claude Code), Google Gemini, and NotebookLM - to accelerate scripting, troubleshooting, runbook generation, and documentation synthesis.
• Build reusable AI-assisted workflows for the team: prompt libraries, knowledge bases, and repeatable analysis patterns.
• Apply responsible AI practices - data handling rules for CUI and proposal-sensitive information, appropriate tool selection, and human review of generated output.
• Automate administration and evidence collection with PowerShell and Microsoft Graph; maintain SOPs, diagrams, and runbooks.
• Implement and evidence NIST SP 800-171 controls supporting CMMC Level 2 readiness; support the ISMS and ISO 27001 audits.

• U.S. citizenship - required for handling Controlled Unclassified Information under DFARS 252.204-7012.
• 4+ years in enterprise IT infrastructure or systems engineering.
• Hands-on on-premises virtualization (vSphere, Hyper-V, or Proxmox) and comfort with physical hardware, racking, and out-of-band management.
• Networking fundamentals: VLANs, routing, DNS, DHCP, VPN, and firewall rule sets.
• Microsoft 365 administration: Entra ID, Exchange Online, SharePoint Online, Teams, and Intune.
• Public cloud experience (AWS or Azure): accounts and subscriptions, networking, and cost management.
• PowerShell scripting for administration and automation.
• Practical, daily use of AI tools for scripting, troubleshooting, or documentation - and the judgment to know when not to trust the output.
• Experience supporting a formal compliance program (CMMC, NIST SP 800-171, ISO 27001, or RMF).
• Proven ability to collaborate with remote teammates and outside vendors with limited direction.
• Bachelor's in IT, Computer Science, or a related field - or an equivalent combination of certifications and hands-on experience.

• Cyber range, red/blue team lab, or training environment buildout.
• Experience building AI-assisted or agentic workflows for an internal team.
• Prior small business or defense contractor experience wearing several hats.
• Certifications (none required): Security+, AZ-104, MD-102, MS-102, AWS Solutions Architect Associate, VCP-DCV, Network+ or CCNA.

• $55,000 – $120,000 annually, commensurate with experience. Full-time, FLSA exempt. Good-faith range per the Maryland Wage Range Transparency Act.
• Hybrid: 2-4 days per week onsite in North Bethesda, MD, driven by lab work. Periodic local travel.
• Medical, dental, and vision; 401(k) with company contribution; PTO and federal holidays. [CONFIRM]
• Company-funded certifications and training, with lab time to pursue them.
• Must be able to lift up to 50 lbs and work in and around equipment racks.
