The Role

The Senior IT Engineer is a force multiplier on our technical team.

This is not a position where you sit in one queue doing the same work every day. Our Senior Engineers rotate through every layer of our service delivery model on a 30-day Tour of Duty cycle - front-line support, scheduled technical work, and project delivery.

There is a reason for that.

We want senior technical knowledge close to the client experience. We want difficult issues solved faster. We want junior engineers learning from senior engineers. And we do not want any part of our technical organization operating in isolation.

You will know which lane you are in, what you own, and what success looks like - but you will also understand how every part of our service model fits together.

You do not just complete work.

You elevate the team and the environment around you.

What You Will Do

• Rotate through our service delivery tiers on a 30-day Tour of Duty cycle, staying connected to the complete client experience
• Own escalations from IT Engineers with accountability through resolution
• Troubleshoot complex technical issues across multiple client environments
• Monitor and remediate device and infrastructure alerts proactively - our clients should not have to call us about problems we should have caught first
• Own complex scheduled technical work from planning through completion
• Participate in and lead technical project delivery, including scoping, planning, implementation, documentation, and handoff
• Mentor and coach other IT Engineers - explaining your reasoning, not simply providing the answer
• Manage Windows Server, virtualization, networking, and hybrid infrastructure environments
• Administer Microsoft 365, Entra ID, Intune, SharePoint, and hybrid identity environments
• Work with firewalls, VLANs, VPNs, DNS, DHCP, wireless, and other network technologies
• Support modern cybersecurity platforms and security-focused configurations
• Identify recurring problems and help eliminate root causes instead of repeatedly treating symptoms
• Document configurations, decisions, root causes, resolutions, and next steps with precision
• Leave every client environment better than you found it

What You Bring

• 3+ years of IT engineering, systems administration, or equivalent hands-on technical experience, preferably within an MSP or multi-client environment
• Strong working knowledge of Windows Server, Microsoft 365, Entra ID, Intune, and modern Microsoft environments
• Strong networking fundamentals, including switching, routing, VLANs, VPNs, firewalls, DNS, and DHCP
• Experience troubleshooting issues that do not have an obvious answer
• Experience managing scheduled technical work and projects - not just reacting to tickets
• The ability to take ownership of a problem and see it through to resolution
• Strong documentation discipline - you leave environments better documented than you found them
• The ability to explain complex technical issues in plain language to clients and coworkers
• A mentorship mindset - you build the people around you, not just the systems around them
• Strong communication skills and professional judgment
• The ability to work in person from our Ankeny, Iowa office and travel to client locations when needed

And just as important:

Attention to detail matters here.

Technical ability can get someone a long way in IT. At Tier 3, ownership, communication, judgment, and attention to detail are what turn a good engineer into a great one.

Nice to Have

• CompTIA Network+, Security+, or Microsoft certifications such as MS-900, AZ-900, or MD-102
• NinjaOne RMM, HaloPSA, or similar MSP platforms
• VMware, Hyper-V, or other virtualization technologies
• Backup and disaster recovery platforms
• WatchGuard or comparable firewall administration
• CrowdStrike, Huntress, or enterprise EDR/XDR platforms
• Microsoft 365 security and Conditional Access
• Azure and hybrid Microsoft environments
• Experience working within mature MSP processes and service delivery standards

Who Thrives Here

See It Through

You own the result, not just the task. The job is not finished until the outcome is achieved.

Own the Mess

When something goes wrong, even when you did not cause it, you step in and help make it right.

Multiply the Team

You share what you know. You teach. You document. You make the people around you better.

Lead With Love

You remember there is a human being on the other side of every ticket, call, email, and problem - and you treat them accordingly, even when the situation is difficult.

Why Tier 3?

A job change should be about more than compensation.

We want Tier 3 to be a place where great technical people can build a career.

You will join a growing company with:

• An Inc. 5000-recognized growth story and ambitious plans for the future
• Clients across the country and exposure to a wide variety of technologies and environments
• A talented technical team that collaborates instead of operating in silos
• Leadership that continues investing in people, tools, cybersecurity, automation, and better ways of delivering IT
• Challenging technical work that will continue stretching your abilities
• Opportunities to lead projects, mentor others, and influence how we operate
• A culture where we take our work seriously without taking ourselves too seriously
• A team that works hard, enjoys working together, and celebrates wins together
• The opportunity to play an important role in where Tier 3 goes next

Our Commitment to You

• $75,000–$95,000 annual compensation, commensurate with experience
• Health benefits
• Paid time off
• A structured 90-day onboarding program designed to set you up for success through hands-on coaching, technical immersion, and process training
• A defined career path with clear expectations and milestones for advancement
• Continued investment in your technical and professional development
• Exposure to challenging projects and technologies across a diverse client base
• A team that takes the work seriously and each other personally

Attention to Detail - Read This

We run one of the most thorough hiring processes in our industry on purpose.

About 70% of applicants do not make it past the first step - not necessarily because they lack technical ability, but because they fail to follow basic instructions.

That matters to us.

Our clients trust us with systems, security, data, and businesses they have spent years building. Small details can have significant consequences. We believe attention to detail starts before someone ever joins our team.
