About The Role
As a Senior System Administrator, you will work as a generalist across IT operations, infrastructure, security, and support. You’ll handle a wide variety of responsibilities — from system administration and device management to security enforcement and vendor management.
While the role is broad by nature, you’ll also have the opportunity to take ownership of specific domains (such as SaaS Systems, AI Automation, or IAM) and become the subject matter expert for those areas.
This hands-on, user-facing role requires technical depth and strong communication skills. You’ll support employees directly, maintain reliable systems, and drive improvements that make IT operations more efficient and scalable.
Please note this role requires you to be on call as part of a shift pattern.

- Maintain accurate IT asset inventory and lifecycle tracking.
- Manage hardware procurement and vendor coordination.
Maintenance & Reliability
- Develop and implement automation solutions to streamline Tier 1 support tasks.
- Build and maintain integrations between IT systems and tools.
- Provide Tier 2/3 support for escalated issues.
- Conduct capacity planning to ensure systems meet business needs.
- Perform performance tuning for infrastructure and services.
Security & Compliance
- Manage access controls and identity management.
- Monitor security events and respond to incidents.
- Enforce IT and security policies across systems and endpoints.
- Apply system hardening and patch management practices.

People & Process
- Create and maintain IT documentation and knowledge base.

- Strong expertise in at least two major domains (e.g., SaaS Systems, AI Automation, Support, IAM), with broad competence across all IT areas.
- Experience leading complex troubleshooting efforts and driving root cause analysis.
- Hands-on experience with:
- Identity & Access Management (JumpCloud, Okta, or similar enterprise IAM).
- Cloud & SaaS platforms (Google Workspace, Microsoft 365, Slack, Zoom).
- Endpoint & Device Management (MDM for macOS, Windows, and mobile devices).
- ITSM platforms (Jira Service Management or equivalent).
- Solid understanding of security principles and compliance frameworks (ISO 27001, SOC2, GDPR) and ability to enforce them in practice.
- Familiarity with IT asset management systems (e.g., AssetPanda).
