Role Description We are seeking an experienced Provisioning Engineer – Subsea Optical Services to support the planning, provisioning, and lifecycle management of lit services delivered over dedicated subsea fibre pairs. This role focuses on high-capacity lit wavelength and spectrum-based services, delivered across Ciena optical transmission platforms. You will be responsible for end-to-end service delivery, from design collaboration and spectrum planning through provisioning, testing, handover, and operational readiness. The environment is technically demanding and change-sensitive, requiring strong engineering discipline, excellent cross-team collaboration, and a deep understanding of subsea fibre-pair capacity, spectrum constraints, and service performance. Key Responsibilities - Optical & Subsea Service Provisioning - Plan, provision, modify, and cease lit 10G / 100G / 400G services across dedicated subsea fibre pairs. - Deliver end-to-end service activation for both On-Net and Off-Net services across resilient and diverse backhaul routes. - Provision services across Ciena 6500 platforms, including: - WaveLogic 5 / WaveLogic 6 - WaveServer platforms - Associated optical shelves, ports, and services - Execute service delivery across protected and unprotected architectures, ensuring compliance with design and SLA requirements. - Spectrum Services & Fibre Pair Capacity Management - Design, provision, and configure Managed and Unmanaged Spectrum services, including: - Quarter fibre-pair increments - Half fibre-pair increments - Manage and optimise optical spectrum allocation on subsea fibre pairs to maximise capacity while protecting in-service channels. - Support modulation, baud rate, and power-level changes to improve spectral efficiency. - Perform capacity management across: - Subsea fibre pairs - Subsea cable systems - Ciena optical transmission networks - Network Design & Cross-Team Collaboration - Work closely with Architecture and Design teams to optimise service routes, optical configurations, and spectrum usage. - Collaborate with Systems and Tools teams to: - Configure alarms and thresholds - Set up SNMP traps and monitoring - Integrate ticketing and incident workflows to support lit and spectrum services - Provide engineering input into new service models, capacity strategies, and network evolution initiatives. - Testing, Validation & Service Handover - Perform end-to-end optical and service testing, including power, OSNR, BER, and path integrity. - Validate services against defined performance SLAs and delivery timescales. - Support controlled migrations, upgrades, and service re-grades within agreed maintenance windows. - Deliver high-quality service handover to customers and operations teams. - Documentation, Operations & Enablement - Produce and maintain: - Engineering Method of Procedures (EMOPs) - End-to-end design sheets and service charts - Handover and support documentation - Support onboarding and inventory accuracy for: - Ciena racks, shelves, ports, and optics - Fibre pairs, spectrum allocations, circuits, and carrier services - Cabling, ODFs, power, and cross-connects - Work with Operations and Service teams to: - Build and refine support procedures - Improve operational readiness for lit and spectrum services - Contribute to service and network availability reporting across Ciena platforms - Training & Knowledge Transfer - Support the development of training materials, procedures, and documentation for NOC and Operations teams. - Act as an escalation and subject-matter expert for complex provisioning and spectrum-related issues. Qualifications - Strong experience planning and provisioning services across Ciena 6500 products and services, including: - WaveLogic 5 / 6 - WaveServer - Spectrum services - Navigator / MCP - Proven experience delivering end-to-end 10G / 100G / 400G lit services. - Solid understanding of: - DWDM and ROADM architectures - Subsea fibre-pair service models - Optical spectrum management and flexible-grid networks - Experience working in high-value, low-tolerance environments with strong change control and governance.
