System Administrator

AccumTech
Ann Arbor, MI
As a System Administrator, you will play a critical role in managing and maintaining on-premises and hybrid environments to ensure stability, security, and performance. This position focuses on day-to-day administration, troubleshooting, and optimization of core infrastructure components, including servers, networking, virtualization, and backup systems. You will also assist in designing and implementing resilient architectures for high availability and disaster recovery across multiple data centers.
The ideal candidate will have strong experience with Windows Server environments, virtualization platforms, networking fundamentals, and best practices in enterprise security.

Primary Responsibilities:
  • Administer and maintain Windows Server environments, Active Directory, and related services.
  • Manage on-prem infrastructure, including firewalls, switches, VLANs, and VPNs.
  • Monitor system performance and uptime; implement proactive maintenance strategies.
  • Perform incident root cause analysis and remediation for infrastructure issues.
  • Manage backup, restore, and disaster recovery processes to meet SLA requirements.
  • Troubleshoot advanced Active Directory and identity-related issues.
  • Maintain documentation for processes, configurations, and procedures.
  • Assist with Incident Response planning and security monitoring.
  • Establish baselines for system performance and capacity planning.
  • Collaborate with internal teams to support infrastructure needs for applications and services.
  • Provide escalation support for helpdesk and technical teams.
Technical Skill Requirements:
  • Strong understanding of networking fundamentals (TCP/IP, VLANs, VPNs, firewalls).
  • Expertise in Windows Server administration and Active Directory.
  • Experience with virtualization technologies (VMware preferred).
  • Knowledge of backup and disaster recovery solutions.
  • Familiarity with syslog, SIEM tools, and event correlation.
  • Understanding of security best practices, RBAC, and least-privilege principles.
  • Ability to design and maintain high-availability and redundant systems.
  • Experience with hybrid environments (basic cloud knowledge is a plus, not primary focus).
Soft Skills:
  • Ability to clearly communicate technical concepts to non-technical stakeholders.
  • Strong documentation and process development skills.
  • Proactive mindset with attention to potential issues and improvements.
  • Comfortable working in cross-functional teams and sharing knowledge.
  • Strong troubleshooting and problem-solving skills.

The annual salary range for this position is $80,000-$100,000.
