Original job 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.

What You'll Be Working On

This is not a traditional "keep the lights on" Systems Administrator position. The goal is to bring in someone who can take ownership of infrastructure operations, lead continuous improvement initiatives, and become the go-to infrastructure resource for the business.

Responsibilities include:

Owning day-to-day infrastructure and operational support

Managing and mentoring the Network Administrator

Partnering with the MSP and managing the vendor relationship

Responding to issues affecting internal users and external clients

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

This role offers significant autonomy and influence, with the objective of allowing the VP, IT to transition away from day-to-day operational IT responsibilities.

Technology Environment

Upcoming Projects

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%
