This Is Not a Typical IT Job
If you are looking for a technical role where you are trusted to solve complex problems, make sound engineering decisions, and directly influence client security, reliability, and compliance, this may be the right opportunity for you.
At Resilient IT, our technicians do more than close tickets.
We support organizations with demanding security, infrastructure, and compliance requirements, including defense contractors and businesses operating in regulated environments. Our managed services and consulting teams work extensively with environments subject to NIST SP 800-171 and DFARS requirements, while our C3PAO practice performs formal CMMC assessments.
We expect a higher level of technical discipline, documentation, accountability, security awareness, and execution.
As a Systems Technician III, you will operate as a senior technical resource across our managed services environment. You will troubleshoot complex issues, design and implement solutions, lead escalations, contribute to infrastructure and security projects, and help develop less-experienced technicians.
This is a hands-on technical position. You are expected to own outcomes, not simply work assigned tickets.

Who You Are
You take ownership.
When an issue reaches you, your objective is not simply to make the ticket disappear. You want to understand what happened, determine why it happened, resolve it correctly, document the solution, and reduce the likelihood that it happens again.
You are also someone who:
- Takes pride in doing technical work correctly
- Thinks critically before making changes
- Understands that security is part of systems administration—not a separate responsibility
- Recognizes that technical decisions can directly affect a client's security and compliance posture
- Is comfortable being accountable for technical decisions
- Communicates proactively rather than waiting to be asked for updates
- Documents work so another technician can understand exactly what was done
- Helps teammates improve rather than guarding knowledge
- Can admit when you do not know something and then methodically find the answer
- Enjoys solving difficult technical problems
- Wants to continue growing technically and professionally
This Role Is Not a Fit For
This position is NOT intended for:
- Entry-level technicians
- Technicians whose experience is primarily desktop support
- Candidates who depend heavily on scripts or step-by-step instructions
- Individuals uncomfortable troubleshooting unfamiliar problems
- Candidates who prefer to avoid client interaction
- Individuals who routinely pass difficult problems to someone else
- Technicians who consider documentation optional
- Candidates looking exclusively for remote work
- Individuals who do not want accountability for the outcome of their work
How You’ll Be Measured
| Performance Expectations |
| Client Satisfaction: Clients receive professional, effective, and proactive service. |
| Technical Quality: Solutions are technically sound, secure, stable, and appropriate for the client environment. |
| Escalation Resolution: Complex issues are driven through resolution with appropriate troubleshooting and root-cause analysis. |
| Ticket Quality: Tickets contain clear troubleshooting steps, findings, actions taken, client communication, and final resolution. |
| Ownership: Issues are actively managed rather than allowed to stall or become someone else’s problem. |
| Responsiveness: Clients and internal team members receive timely communication and updates. |
| Repeat Issues: Recurring incidents are investigated and addressed rather than repeatedly treated as isolated tickets. |
| Project Execution: Assigned technical projects are planned, communicated, documented, and completed successfully. |
| Security & Compliance: Technical work supports secure operations and applicable requirements, including NIST SP 800-171 where relevant. |
| Team Development: Junior technicians benefit from your knowledge, guidance, and technical leadership. |
| Continuous Improvement: You identify opportunities to improve client environments, documentation, processes, and service delivery. |
