Independent Technical Judgment

Experience needs to go beyond performing tasks the candidate has already been shown how to do.

The engineer should be able to:

• Take an unfamiliar issue and determine where to start.
• Establish facts before making assumptions.
• Form and test a technical hypothesis.
• Explain what they are testing and why.
• Adjust the course when the results do not support the original assumption.
• Troubleshoot beyond a checklist or runbook.
• Research and validate unfamiliar issues before making production changes.
• Determine root cause when reasonably possible.
• Know when to continue troubleshooting and when to involve a team lead, senior engineer, or vendor.

Ownership / Teamwork

• Drives escalated issues toward resolution or a clear next action.
• Documents troubleshooting, findings, changes, and resolution.
• Clearly communicates what has been tested, what was found, and what help is needed.
• Works independently without operating in a silo.
• Collaborates with team leads and senior engineers.
• Helps Tier 1/Tier 2 technicians improve rather than simply taking over.
• Takes accountability for mistakes and corrects them.
• Raises questions or concerns before they become larger problems.

Qualifications:

• 5+ years of IT support or systems engineering experience.
• MSP or multi-client support experience.
• Proven experience independently owning and resolving Tier 2/Tier 3 escalations.
