L3 Systems Engineer

We are looking for an experienced Level 3
Systems Engineer who can solve complex technical problems, design and implement
solutions, lead projects, mentor other technicians, and serve as a senior
technical escalation resource.

This position combines advanced Tier 3
technical support with systems engineering, cloud infrastructure, networking,
cybersecurity, and project responsibilities.

When Tier 1 and Tier 2 technicians
encounter difficult server, Microsoft cloud, networking, cybersecurity, or
infrastructure problems, you are one of the people they escalate to.

You will also design, implement, migrate,
secure, and improve client technology environments.

You should be comfortable independently
investigating complex technical problems, developing a plan, implementing a
solution, and communicating with the client throughout the process.

Candidates whose experience is primarily
desktop support, helpdesk, or Microsoft 365 administration without meaningful
hands-on Windows Server experience will not meet the technical requirements of
this position.

  Directory
  
• Strong hands-on Microsoft
  Windows Server experience is required.

  identify problems, and independently develop a solution.
  
• Microsoft 365, Azure, and Cloud
  Engineering
  
• Modern client environments
  increasingly combine traditional infrastructure with cloud-hosted services.
  
• You must be comfortable
  supporting both, including traditional Active Directory, hybrid Active

• Apply cybersecurity best
  practices when designing and implementing technical solutions
  
• Systems Engineering and
  Advanced Escalations
  
• Own complex technical
  escalations from diagnosis through resolution
  
• Perform root-cause analysis and
  design long-term solutions rather than relying on temporary fixes
  
• Analyze logs, monitoring data,
  packet captures, and other diagnostic information to resolve complex issues
  
• Work directly with vendors on
  advanced technical issues
  
• Identify opportunities to
  improve client technology environments
  
• Clearly communicate technical
  findings, business impact, and recommended solutions

  will also support backup and disaster-recovery environments, troubleshoot
  backup failures, perform restores and recovery testing, and assist during major
  recovery events.
  
• Mentoring and Technical
  Leadership
  
•  A Level 3 Systems Engineer
  should make the entire technical team stronger
  
• You will:
  
• Mentor Tier 1 and Tier 2 technicians and review their technical
  escalations
