Build complex IT environments. Deliver successful projects. Make an impact.

First Call Computer Solutions is looking for an experienced Tier 3 Professional Services Engineer to join our Professional Services team. This role is designed for senior engineers who thrive on implementing complex infrastructure projects, leading technical delivery, and turning approved designs into stable, secure, production-ready environments.

You'll work closely with Project Managers, fellow engineers, and clients to deliver predictable, high-quality outcomes through disciplined project execution, effective communication, and adherence to First Call’s implementation standards. Success in this role requires both advanced technical expertise and a commitment to consistent project delivery that builds long-term client confidence.

If you enjoy solving challenging technical problems and seeing projects through from kickoff to successful completion, we’d like to talk.

The ideal candidate understands that exceptional client outcomes require more than technical skill—they require planning, communication, accountability, and consistent execution throughout every phase of a project.

Required Experience

• 7+ years implementing business IT infrastructure
• MSP or IT consulting experience strongly preferred
• Proven experience delivering customer-facing infrastructure projects from planning through production
• Strong troubleshooting, planning, organizational, and time management skills
