About SUBCO

With a proven track record of delivering transformative connectivity, SUBCO owns and operates critical submarine cable assets linking Australia to Asia, the Middle East, and beyond. Building on this foundation, a new 5,000 km domestic cable system - connecting emerging digital hubs across Australia - is set to go live in 2026, marking a major milestone in SUBCO’s evolution.

As demand for high-capacity, resilient infrastructure accelerates, SUBCO is entering a strategic growth phase of major scale up, actively pursuing global opportunities to deliver innovative connectivity solutions that meet the needs of cloud, content, and AI-driven enterprises.

We’re looking for a NOC Engineer to join the SUBCO Team as we enter an exciting new phase of growth – someone eager to be at the forefront of innovation, digital infrastructure and global subsea network expansion.

At SUBCO, our values are the foundation of everything we do. As a NOC Engineer based out of London, you will join a small, high-performing global team responsible for 24x7 monitoring, incident response, and operational support of Subco’s international optical and IP networks. Working within a rotating shift roster, you’ll monitor network performance, resolve incidents, manage stakeholder communications, and execute change activities to ensure service continuity across critical infrastructure.

You’ll work with industry-leading tools and systems and collaborate across continents to uphold the performance and resilience of SUBCO’s digital backbone.

• Proactively monitor all network infrastructure, including fibre systems, optical transmission, IP routers/switches, and environmental telemetry using tools like MCP, Observium, and New Relic.
• Triage and resolve network events and incidents in accordance with SLAs, escalating appropriately via Jira Service Management.
• Participate in the change management process, including peer review and execution of MOPs to support routine maintenance and network upgrades.
• Collaborate closely with Australian-based Engineers during shift handovers, ensuring full context and documentation are preserved.
• Support continuous improvement by identifying incident trends, participating in post-incident reviews (PIRs), and helping evolve monitoring rules and automation alerts.
• Assist in the training and onboarding of new team members as required.

Qualifications:

• Qualification in Telecommunications Engineering (or actively working toward one), or equivalent experience in a network operations environment.
• Proven experience operating in a 24x7 NOC or network support function across IP and optical domains.
• Strong knowledge of transmission, long-haul, subsea, and optical networks (DWDM, MPLS, BGP, Ethernet).
• Skilled in network performance troubleshooting and event triage within complex global network environments.
• Familiarity with Data Centre environments including rack management, power, and thermal considerations.
• Understanding of security compliance and physical access control processes within telecommunications facilities.
• Working knowledge of ITIL v3 or v4 principles including Service Operations and Service Transition.
• Experience with monitoring, alerting, and observability platforms such as Observium, MCP by Ciena, and New Relic.
• Strong documentation habits, including incident summaries, PIRs, and shift handover reports.

Additional Information:

• Occasional international travel.
• Self-motivated team player, adaptable to shift-based work and remote collaboration with global colleagues.
• Be involved in infrastructure projects that will prove critical to Australasia’s digital future.
• Work alongside globally recognised industry thought leaders, transforming the backbone of our digital ecosystem.
• Fully remote role working within an international team.
