Description
As a Senior Systems Administrator at Omnidian, you will be a technical force multiplier during a period of rapid global expansion. You are a self-directed architect who thrives in high-growth environments, enjoys owning and improving systems, proactively leveraging modern AI tools to automate complex workflows and engineer resilient infrastructure.
You will spend 60% of your time leading high-impact IT projects, 20% on proactive security remediation, and 20% providing Level 2+ support for our global, asynchronous workforce across the US, Australia, and Latin America. This role is primarily focused on project-based work and owning infrastructure improvements, with limited reactive support responsibilities.
What You'll Do
Project Leadership & Mentorship
High-Stakes Execution: Lead the implementation and lifecycle management of high-stake infrastructure projects (IDP, MDM, ITAM) from conception to full completion.
Technical Mentorship: Serve as a senior technical escalation point and mentor junior IT staff , fostering a culture of continuous learning
Architectural Oversight: Contribute to architectural decisions for SharePoint Online, ensuring site designs meet the specific data-governance needs of Finance and Legal while maintaining audit readiness.
Global Infrastructure Scaling: Own, support, and implement infrastructure solutions to meet sudden demand spikes, particularly during international expansion, Mergers & Acquisitions (M&A), and the onboarding of offshore staff.
Security & Compliance
Vulnerability Remediation: Partner with the Information Security Team and senior IT staff to swiftly execute tasks required to remediate security findings and vulnerabilities within SOC2 and ISO frameworks.
DR & BCP Support: Support and contribute to the development and testing of Disaster Recovery (DR) and Business Continuity Plans (BCP), primarily managed by the Information Security Team.
Technical Standards: Establish and maintain technical designs and configuration baselines for all managed workstations, ensuring no “configuration drift” occurs across the global fleet.
Advanced Support & Operations
L2+ Technical Escalation: Provide high-level engineering support for complex hardware and software issues for a remote global team that exceed standard specialist capabilities.
Observability & Monitoring: Design and maintain monitoring and observability frameworks to proactively track global system health and maintain high situational awareness.
Vendor & Roadmap Alignment: Interact with key SaaS and infrastructure vendors to understand product roadmaps and articulate complex technical requirements for internal projects.
Cloud Application Management: Provide deep technical management for the global cloud stack, including Google Workspace, GCP, Endpoint Detection & Response (EDR), and CRM solutions.
Operational Excellence & AI Integration

Knowledge Management: Act as a lead contributor to the team Knowledge Base, ensuring that project-level architectural decisions and troubleshooting workflows are documented as "living" resources.
Who You Are
High-Stakes Project Leader: You have a proven track record of driving complex infrastructure projects to successful completion under pressure.
Independent Critical Thinker: You bring the situational awareness to understand the "downstream" effects of technical decisions and act swiftly to prevent small issues from becoming global incidents.
Autonomous Architect: You don't just follow a roadmap; you help build it by identifying infrastructure gaps and proposing technical solutions with a bias for action.
AI-Augmented Mindset: You proactively use AI tools like Gemini and Claude AI to increase your "speed-to-solution" for troubleshooting, process development, and documentation.
Global Communicator: You are comfortable working across time zones and possess the articulate communication skills required to lead cross-functional projects.
Experience You’ll Need
Proven Project Leadership: Demonstrated experience leading high-stake IT infrastructure projects from initiation to full delivery and documentation.
Professional Experience: 4+ years in systems administration or infrastructure engineering in a high-growth environment.
Certifications: ITIL 4 Foundation is required. Project management certification/experience is a plus.
