Senior Systems Administrator

At Horizontal Digital, we hold ourselves to one key belief: You’re only as good as your worst customer experience. This mantra is what drives our digital consultancy to think beyond the easy answers and instead create websites, apps, portals and other experiences that solve customer needs for Fortune 500 companies in intuitive and empathetic ways. And we make this lofty standard a reality by fusing strategy, data, design and technology together to arrive at solutions that set the bar higher for everyone. 

We use these values to fuel superior results: 

Lock arms 
We forge relationships that make our impact 1,000x stronger. This means working across departments and engaging both our clients and our communities to deliver the greatest good. 

Show hustle 
We’re not ones to sit on our hands and wait. Instead, we anticipate opportunities, collectively roll up our sleeves and find ways to execute the exceptional. 

Embrace change 
From new technologies to workplace philosophies, we welcome the unexpected and constantly anticipate what’s next. 

Elevate empathy 
We listen before we take action. This means understanding a variety of perspectives and holding ourselves to a higher standard of accountability. 

Never settle 
We motivate each other to push past the easy answers and collectively arrive at bigger, more inspiring ideas. 
  
But enough about us. Let’s talk about you.  
  
We’re looking for a Senior Systems Administrator to serve as a technical backbone of our IT operations. You’ll own the systems that keep Horizontal Digital running including endpoint management, identity and access, Microsoft 365, security tooling, and compliance platforms, while mentoring a growing IT team and leading the internal side of infrastructure projects like our migration to Microsoft Intune and the rollout of data protection tooling. If you thrive on solving hard problems across a broad technology stack and want a role where your decisions directly shape how a company operates, this is it. 

What you’ll do:  

• Serve as a senior technical resource on the IT team, mentoring the less experienced IT team members, and acting as an escalation point for complex issues 

• Oversee endpoint management strategy and execution (currently Workspace One, migrating to Microsoft Intune), including configuration profiles, compliance policies, application deployment, and patching 

• Administer Active Directory, Okta SSO, Microsoft 365 (Exchange Online, Teams, SharePoint), and manage licensing strategy and cost optimization across the M365 tenant 

• Serve as the internal technical lead during implementation of data loss prevention tooling (Microsoft Purview or equivalent) and data classification initiatives supporting ISO 27001 compliance 

• Develop and execute PowerShell and Bash scripts to automate administrative tasks, enforce security policies, and generate operational reporting 

Who you are:  

• A seasoned IT professional with 5+ years of hands-on systems administration experience who thrives on owning a broad technology stack rather than specializing in one narrow area 

• A natural mentor who enjoys helping junior team members grow, and who leads by example through strong documentation, clear communication, and consistent operational discipline 

• A strong problem-solver who can methodically troubleshoot across endpoints, identity systems, cloud services, and networking without needing to escalate 

• Someone comfortable serving as the bridge between third-party consultants and internal stakeholders during infrastructure projects, ensuring quality and knowledge transfer 

• A security-minded operator who instinctively thinks about access controls, data protection, and compliance implications when making infrastructure decisions 

• A proactive communicator who can translate technical concepts for non-technical audiences and advocate for IT needs to leadership 

• Someone energized by the pace of a growing organization where priorities shift, new tools emerge, and no two weeks look the same 

What you bring:   

• Associates or Bachelor’s degree in IT, Computer Science, Information Systems, or a related field (or equivalent experience).
• 5+ years of experience in IT systems administration, infrastructure management, or a related hands-on technical role
• Demonstrated hands-on experience with MDM platforms such as Microsoft Intune, Jamf, Workspace One, or equivalent tools.
• Experience supporting both Windows and macOS environments, preferred.
• Deep knowledge of Active Directory a
