About the role

Position Summary

Reporting to the Director of IT Infrastructure, the Senior IT Systems Administrator plays a critical role in owning, scaling, and securing Harness’ corporate IT environment. This is a hands-on, senior individual contributor role focused on identity, SaaS platforms, device management, automation, and security in a fast-growing, global company.

This position is ideal for someone who has already operated at scale, is comfortable owning systems end-to-end, and thrives in environments where automation, security, and user experience matter.

About the role

Core Systems

  • Administer identity and access management platforms (Okta, SSO, SCIM, lifecycle workflows)
  • Manage and optimize SaaS applications (Google Workspace, Microsoft 365, Atlassian, Slack, etc.)
  • Lead device management for macOS and mobile platforms using MDM solutions (Kandji (Iru), ManageEngine)
  • Serve as a primary SME for core corporate IT systems

Automation & Efficiency

  • Design, build, and maintain automation workflows using Workato, BetterCloud, Okta Workflows, and similar tools
  • Identify manual or error-prone processes and proactively replace them with scalable automation
  • Partner with internal teams to deliver automation that improves efficiency and employee experience

Security & Reliability

  • Maintain a security-first mindset across identity, endpoints, SaaS, and access controls
  • Support and improve endpoint and infrastructure security (SentinelOne, Qualys, RBAC models)
  • Participate in system monitoring, incident response, and root-cause analysis
  • Assist with networking and infrastructure initiatives (Meraki, Cisco)

Operational Excellence

  • Lead and execute IT projects from design through delivery
  • Provide Tier-3 level troubleshooting and escalation support
  • Create and maintain high-quality documentation, runbooks, and knowledge base articles
  • Participate in a rotating on-call schedule
  • Ability to travel between company offices on an as-needed basis to support infrastructure projects, deployments, and on-site initiatives, including office buildouts, technology setups, and the resolution of complex on-site issues
  • Perform other duties as assigned, consistent with the role

About you

Experience

  • 5+ years in a similar role in a growing or enterprise environment
  • Experience supporting 1,000+ end users across multiple locations
  • Proven ability to operate independently and own systems without heavy oversight

Technical Strength

  • Deep experience with:
  • Google Workspace
  • Okta (SAML/OIDC, SCIM, Lifecycle Management, Workflows)
  • Atlassian, Slack, BetterCloud
  • Kandji MDM (profiles, patching, library items)
  • Strong macOS and Windows 11 administration experience
  • Solid understanding of networking fundamentals (DNS, routing, hardware basics)

Security & Architecture

  • Strong grasp of access controls, RBAC, and security best practices
  • Experience applying security frameworks in day-to-day operations
  • Comfortable balancing security requirements with user experience

Project & Communication Skills

  • Demonstrated success leading IT projects (email migrations, SaaS rollouts, VoIP, security initiatives)
  • Excellent communication skills with both technical and non-technical audiences
  • Clear documentation and structured problem-solving approach
  • The position requires a balance of proactive project work and reactive support, with the flexibility to pivot between long-term initiatives and immediate technical issues.

Nice to Have

  • Scripting experience (Bash, PowerShell, Python)
  • Experience integrating or leveraging AI-driven IT tools
  • Prior experience in high-growth or SaaS companies

Why This Role Is Different

  • You’ll own systems, not just tickets
  • Heavy emphasis on automation and scale, not manual admin work
  • Partnership with security, engineering, and business leaders
  • Influence over tooling, architecture, and IT standards
