Sr. Subsea Network Operations Center (NOC) Technician

Job Description

Job Description

OVERVIEW:
SILTT is searching for a dynamic and highly motivated Subsea Network Operations Center (NOC) Technician to serve as a Tier III technical authority for our global undersea cable infrastructure. This role acts as the final escalation point for the monitoring, maintenance, and restoration of critical subsea optical paths, providing expert-level troubleshooting for complex physical-layer anomalies—including shunt faults, fiber attenuation, and Power Feed Equipment (PFE) instabilities—to ensure rapid service restoration during Priority 1 and Priority 2 events. By driving deep-dive Root-Cause Analysis (RCA), managing high-stakes coordination with marine maintenance vessels, and spearheading proactive network grooming, this position serves as the critical bridge between Subsea Engineering and Real-Time Operations. If you are a seasoned technical leader ready to sustain global connectivity and mentor a world-class team from our San Diego operations hub, we encourage you to apply today!

WHO WE ARE:
At SILTT we’re pushing the limits of infrastructure innovation in the Telecommunications and Information Technology industry. From delivering world-class modular data center facilities to all-hours, 365-day operational response and disaster recovery, our multi-functional team of experts are force multipliers across the infrastructure landscape. We pride ourselves in leading from the front to advise, assist, and accompany our clients through their toughest technological and operational challenges. We always deliver results ( spelled “re-SILTTs”)!

WHY SILTT?
At SILTT, “objective-driven” means first being “people-driven”. As a small business we know that the ability to achieve our mission demands we take care of our own by providing our team members with a variety of benefits that allow them to live fulfilling, healthy, balanced, meaningful lives. That’s why we believe in offering paid healthcare, ultra-competitive 401K matching, accrued paid time off and fixed holiday leave, continuous learning and professional development incentives, and promote a sustainable work-life balance.

As we charge ahead in the competitive world of technology and sustainment, we need a strong Subsea Principal/Senior NOC Network Technician to support our current and future projects. This critical position will collaborate with fellow SILTT teammates, stakeholders and executive leadership.  As we staff up to support a new program, this Principal/Senior NOC Network Technician will have the opportunity to be on the ground floor and help define the trajectory of our future!

A DAY IN THE LIFE:
In this role, you will support a high-impact Network Operations Center that forms the backbone of global subsea service delivery. This role provides the opportunity to modernize NOC best practices and shape a world-class operations culture that scales while maintaining customer trust and operational excellence in a mission-critical subsea environment. Key responsibilities include, but are not limited to:

Incident and Problem Resolution:

• Spectrum Sharing Modules (SSM), Power Feed Equipment (PFE), and terrestrial backhaul connectivity (DWDM, Coherent Optics, OTN).
• Support root-cause analysis (RCA) for cable faults and implement corrective actions for recurring system instabilities.
• Collaborate with Incident managers during P1/P2 events (e.g., cable cuts), providing technical direction for traffic restoration via restoration pairs or diverse paths.
• Interface with marine maintenance authorities, cable ships, and subsea vendors to expedite undersea repairs or hardware replacement (RMA).

Network Maintenance and Change Implementation:

• Plan and execute approved maintenance on subsea wet-plants and dry-plants following CAB authorization and MOP standards.
• Conduct firmware upgrades on transponders, gain equalization adjustments, and validation testing on submerged repeaters and branching units.
• Ensure adherence to change control and documentation standards, maintaining strict rollback and verification plans for high-latency transoceanic circuits.
• Review and validate post-change outcomes, reporting optical SNR (Signal-to-Noise Ratio) metrics and identifying improvement opportunities.

Monitoring and Optimization:

• Tune optical monitoring thresholds and alarms to differentiate between seasonal "ocean noise" and genuine system degradation.
• Use NMS and specialized subsea tools (Coherent OTDR, COTDR, Unit-specific Element Managers) to identify fiber anomalies and performance trends.
• Recommend and implement proactive measures to enhance network resilience, such as optimized power feeding or automated rerouting.
• Collaborate with Marine Engineering and QA teams to update optical baselines and improve emergency runbooks.

Documentation and Knowledge Sharing:

• Maintain accurate and version-controlled documentation for straight-line diagrams (SLDs), cable landing station (CLS) layouts, and link budgets.
• Contribute to the continuous improvement of the Subsea NOC Knowledge Base (KB) regarding specific cable system architectures.
• Mentor and train Level I and Level II NOC staff through hands-on guidance in optical physics and peer review sessions.

BASIC QUALIFICATIONS:

• Bachelor’s degree in Electrical Engineering, Telecommunications, or a related technical discipline preferred; equivalent professional experience and specialized training may be considered in lieu of a formal degree.
• BICSI certified Technician (TECH) preferred, other BICSI or equivalent optical/marine certifications may be considered.
• 8+ years of experience in enterprise or service provider network operations, with a heavy emphasis on optical transport and subsea systems.
• Strong technical expertise in high-capacity transport (Ciena, Infinera, Nokia, NEC, SubCom), DWDM, and subsea power feeding.
• Deep understanding of OTDR/COTDR, Optical Link Budgets, Q-factors, Chromatic Dispersion, and PMD.
• Experience with NMS, ITSM, and logging platforms (ServiceNow, SolarWinds, Splunk, or vendor-proprietary EMS).
• Working knowledge of scripting or automation tools (Python, Ansible, or similar) for managing large-scale optical fleets preferred.
• Certifications: CCNP (required), JNCIP, or equivalent advanced vendor certification preferred; ITIL v4 Foundation a plus.

SKILLS & COMPETENCIES:

• Advanced Optical Diagnostics and Subsea Troubleshooting
• Root Cause and Problem Analysis (Wet-plant vs. Dry-plant)
• Change Implementation and CAB Readiness
• Mentoring and Technical Leadership
• Monitoring Optimization and Automation Awareness
• Documentation Quality and Regulatory Compliance (ICPC standards)

ABILITY TO WORK REMOTE:
The work associated with this role is expected to be performed on-site at our San Diego Area location, though some travel may be required for periodic support as needed.
