Description

Robert Half is exclusively partnered with a well-established organization in Newmarket that is looking to hire a Senior Systems Administrator to lead infrastructure, security, and IT operations across the business.

This is a highly visible role that combines hands-on technical leadership with stakeholder engagement, vendor management, and strategic planning. The successful candidate will play a key role in modernizing the environment while helping the organization move further toward a cloud-first future.

• Identifying opportunities for infrastructure improvements and modernization

• Making security recommendations and driving best practices

• Supporting disaster recovery, redundancy, and business continuity initiatives

• Leading and contributing to infrastructure-related projects

• Acting as a trusted technology advisor to leadership and business stakeholders

What We're Looking For

• 5+ years of infrastructure, systems administration, or IT operations experience

• Strong Microsoft infrastructure expertise

• Experience supporting hybrid cloud environments

• Network, security, and systems administration experience

• Strong troubleshooting and problem-solving skills

• Experience managing vendors or MSP relationships

• Excellent communication and stakeholder management abilities

• Comfortable working directly with clients and senior leadership

• A passion for technology and continuous improvement

• Automation mindset with PowerShell or similar scripting experience

Why Consider This Opportunity?

• Opportunity to become the senior infrastructure leader within the organization

• Broad ownership across infrastructure, security, operations, and vendor management

• Executive visibility and influence

• Stable organization with a long-tenured technology team

• 100% employer-paid benefits

• RRSP matching up to 6%
