How much do undersea cable jobs pay per hour?

As of Jul 5, 2026, the average hourly pay for undersea cable in the United States is $22.37, according to ZipRecruiter salary data. Most workers in this role earn between $19.23 and $24.52 per hour, depending on experience, location, and employer.

What are the key skills and qualifications needed to thrive as an Undersea Cable Engineer, and why are they important?

To thrive as an Undersea Cable Engineer, you need expertise in electrical and telecommunications engineering, knowledge of fiber optic technology, and often a relevant engineering degree. Familiarity with specialized cable-laying vessels, GIS mapping software, and industry standards such as ITU and IEEE is typically required. Strong problem-solving abilities, teamwork, and adaptability are vital soft skills for working in challenging and remote environments. These competencies ensure reliable global communications infrastructure and minimize downtime during installation and maintenance.

What are some common challenges faced by professionals working in undersea cable roles, and how can they be managed?

Professionals in undersea cable roles often encounter challenges such as working in remote or offshore locations, dealing with unpredictable weather conditions, and coordinating with international teams across different time zones. Effective communication, strong project management skills, and adaptability are crucial for overcoming these obstacles. Additionally, staying current with the latest advancements in submarine cable technology and adhering to stringent safety and environmental regulations can help ensure smooth operations and career success.

What is the difference between Undersea Cable vs Submarine Cable Installer?

AspectUndersea CableSubmarine Cable Installer
Primary RoleDesign, manufacturing, and maintenance of undersea communication and power cablesInstallation and repair of submarine cables on-site
Work EnvironmentResearch labs, manufacturing facilities, planning officesOffshore, on ships, and at installation sites
CredentialsEngineering degrees, technical certificationsTechnical certifications, maritime training
Industry UsageTelecommunications, energy sectorsTelecom companies, specialized installation firms

Undersea Cable professionals focus on the design and maintenance of cables, often working in labs or offices. In contrast, Submarine Cable Installers are hands-on workers who physically install and repair cables offshore. Both roles require technical skills, but their work environments and responsibilities differ significantly.

What are undersea cables?

Undersea cables, also known as submarine cables, are specialized cables laid on the seabed between land-based stations to transmit telecommunication signals across stretches of ocean and sea. They are primarily used for international data and voice communication, carrying about 99% of the world's internet traffic. These cables are engineered to withstand harsh underwater environments and can span thousands of kilometers, connecting continents and enabling global connectivity. Their installation and maintenance require specialized ships and technology, making them a critical part of the global communications infrastructure.

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 anomaliesincluding shunt faults, fiber attenuation, and Power Feed Equipment (PFE) instabilitiesto 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 were 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. Thats 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).
