• Assist in identifying performance trends, capacity constraints, and emerging issues before they impact services or customers.
• Partner with experienced engineers to deploy, optimize, and scale network infrastructure supporting AI and other demanding workloads.
• Investigate incidents, perform root cause analysis, and drive issues to resolution.
• Participate in network upgrades, implementations, testing, and operational improvement initiatives.
• Continuously expand technical expertise through hands-on experience, self-directed learning, mentorship, and training opportunities.
• Travel up to 20% as needed to support deployments, installations, maintenance activities, and operational support.
Required Qualifications:
• Strong troubleshooting, analytical, and problem-solving skills.
• Self-motivated with a strong sense of ownership, accountability, and follow-through.
• Excellent communication and collaboration skills.
• Ability to work effectively in a fast-paced environment where technology is continuously evolving.
• Willingness and enthusiasm to continuously learn and develop new technical skills.
• Ability to travel up to 20% (domestic and international).
Preferred Qualifications:
• Familiarity with networking fundamentals, including TCP/IP, routing, switching, VLANs, SNMP, and basic network troubleshooting.
• Experience with monitoring, telemetry, observability, alerting, or performance management tools.
• Exposure to Linux systems or Linux-based Network Operating Systems (NOS).
What Will Make You Successful:
• You are naturally curious and enjoy investigating how systems and technologies work.
• You take initiative and actively seek opportunities to improve processes, systems, and your own technical skills.
• You are comfortable tackling unfamiliar technologies and enjoy learning through hands-on experience.
• You take ownership of problems and remain engaged until they are resolved.
