POSITION SUMMARY:

The Senior Network Operations Engineer is the senior-most technical role within CENIC's Network Operations Center (NOC), with a strong background in 24x7 NOC environments and experience with service provider networks. This role serves as the primary escalation point for Network Operations Engineers, handling complex, ambiguous, and long-running incidents that fall outside standard triage workflows, and provides technical oversight of shift-level incident handling in the absence of a Lead. The Senior Network Operations Engineer also drives strategic projects to improve NOC tooling, workflows, and operational maturity, serving as the technical owner for key systems and initiatives. This role has no supervisory responsibility, but is expected to function as a technical authority and mentor for Network Operations Engineers and Administrators across shifts.

ESSENTIAL FUNCTIONS:

1. Serve as the primary escalation point for Network Operations Engineers, providing technical guidance and hands-on troubleshooting support for issues that exceed standard triage scope

2. Lead the resolution of complex, ambiguous, or long-running incidents that fall outside normal incident management workflows, coordinating cross-team input as needed and driving issues to closure

3. Own and execute strategic projects that improve NOC tooling, workflows, and operational efficiency, including serving as technical owner for key monitoring and operational systems, such as Zabbix, Jira, and CONC

4. Step into standard shift triage duties as needed to cover staffing shortfalls, performing the full scope of triage engineer responsibilities during those periods

5. Provide triage oversight during shifts when a supervisor is unavailable, ensuring incidents are being handled correctly, escalations are appropriately routed, and documentation standards are maintained

6. Identify recurring or systemic issues surfaced through escalations and incident handling, and propose process or tooling improvements to reduce repeat occurrences

7. Document complex incident resolutions and escalation outcomes thoroughly, contributing to the NOC's knowledge base and post-incident review process

8. Mentor and provide technical guidance to NOC staff, supporting skills development and consistent application of operational best practices

9. Keep current with emerging trends and technologies relevant to service provider and research/education networking, applying relevant developments to NOC tooling and processes

KEY SUCCESS FACTORS:

1. Expert-level technical knowledge of NOC operations and large-scale IP and optical network troubleshooting

2. Sound judgment and composure when handling ambiguous, complex, or long-running incidents without established playbooks

3. Strong sense of ownership and follow-through on strategic projects, from initial scoping through implementation and adoption

4. Excellent oral and written communication skills, including the ability to communicate clearly with Operations staff, Leads, and leadership

5. Well-organized and able to manage multiple concurrent priorities across escalations, incidents, and project work

6. Strong troubleshooting and analytical skills, with the ability to diagnose issues that have resisted standard triage approaches

7. Collaborative mindset and effectiveness working across shifts, teams, and with minimal direct oversight

8. Strong commitment to mentorship and the professional development of less experienced Operations staff

REQUIRED EDUCATION AND/OR EXPERIENCE:

1. Bachelor's degree in Computer Science or related discipline with 6 years or more of experience, or a combination of education and experience

2. Experience with MPLS (Segment Routing, LDP, RSVP-TE), L2VPN, and IPVPN services (EVPN or similar), and traffic engineering in a large-scale production environment

3. Experience mentoring or informally leading technical staff in a NOC setting

4. Familiarity with network automation tools such as Ansible, NSO, Git, Python, and other automation processes
