Deploy and configure infrastructure for new client onboarding, supporting connectivity, integrations, authentication, and ongoing environment needs.
Administer Microsoft Active Directory across multiple AWS tenants and trusted domains, including GPOs, DNS, DHCP, DFS/DFSR, domain trusts, permissions, and role-based access.
Configure and support secure client access using SAML2, SSO, Identity Providers (IdP), VPNs, and related authentication technologies.
Maintain the security, availability, and compliance of cloud and Windows infrastructure, including vulnerability remediation, operational controls, and support for annual SOC 2 Type II audits.
Monitor infrastructure health and proactively identify performance, reliability, security, and cost optimization opportunities, including rightsizing and removing unused AWS resources.
Troubleshoot complex application, networking, authentication, and infrastructure issues, partnering with developers, DBAs, QA, technical leads, and clients through resolution.
Support hybrid connectivity between AWS and Siepe corporate infrastructure, including Meraki SD-WAN, and use PowerShell, Terraform, AI tools, and automation to streamline deployments and infrastructure operations.
Maintain accurate system documentation and operational knowledge, track work and service requests in ConnectWise PSA, and provide regular visibility into progress, risks, issues, and remediation activities.
What You’ll Bring
Extensive experience supporting enterprise Windows infrastructure in AWS, including large-scale EC2 environments and multi-tenant cloud infrastructure.
Advanced knowledge of Microsoft Active Directory, including domain trusts, GPOs, DNS, DHCP, DFS/DFSR, identity management, and access controls.
Strong networking expertise across Layer 3 routing, firewalls, VPNs, and SD-WAN, with familiarity with Meraki technologies.
Experience supporting Microsoft SQL Server, Windows application servers, and web server environments.
Strong understanding of infrastructure security and operations, including vulnerability management, patching, backups, monitoring, endpoint management, and security best practices.

Experience with AWS cost optimization and cloud governance, with familiarity with SOC 2 Type II controls and compliance requirements.
Strong troubleshooting, communication, and documentation skills, with the ability to independently manage multiple environments and competing priorities in a fast-paced environment.
