  • Own the reliability, availability, and operational health of LDAP, SMTP, DNS, DHCP, and other Unix-based infrastructure services.
  • Manage day-to-day operations, incident response, troubleshooting, performance tuning, and capacity planning.
  • Lead infrastructure projects, including solution design, deployment, upgrades, and service modernization.
  • Drive automation through scripting and configuration management to improve efficiency and scalability.
  • Design and maintain highly available, secure, and resilient infrastructure across on-premises, cloud, and hybrid environments.
  • Implement monitoring, alerting, and observability practices to improve service reliability and operational visibility.
  • Partner with cross-functional teams on enterprise initiatives and provide technical leadership for infrastructure services.
  • Develop operational standards, documentation, and best practices.

Who You Are

  • You demonstrate strong leadership during critical incidents, rapidly assessing system failures, coordinating response efforts, and driving resolution while maintaining clear communication with stakeholders
  • You develop automation and infrastructure code with maintainability in mind, ensuring documentation and implementation clarity that enables team members to support and extend your work
  • You communicate complex technical concepts effectively across organizational levels, translating infrastructure challenges into clear business context for leadership and detailed guidance for engineering teams
