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
