Product Line Manager – Mobile Core Service Assurance

VIAVI Solutions is seeking a Product Line Manager to own the evolution and commercial success of its NITRO Mobile core service assurance portfolio. The role drives product strategy, roadmap, architecture, lifecycle management, and market success, working across engineering, data science, marketing, and sales to deliver cloud-native observability and AI-driven insights for communication service providers.

Responsibilities:

• Own the end-to-end product lifecycle for assigned NITRO Mobile core service assurance modules, from inception and market requirements definitions (PRDs/MRDs) to development, launch, and eventual sunset
• Define the multi-year portfolio roadmap, balancing tactical customer commitments with long-term strategic evolution toward automated network operations and network slicing assurance
• Champion cloud-native observability paradigms, ensuring NITRO Mobile platforms gracefully handle high-throughput 5G user-plane (UPF) and control-plane telemetry
• Translate complex 3GPP standards and service-based interfaces into actionable software requirements for data collection, probe ingestion, and analytics dashboards
• Drive integration with modern orchestration and data layers, ensuring alignment with industry automation benchmarks such as TM Forum Open APIs
• Collaborate with engineering and data science teams to specify and validate machine learning-driven anomaly detection, predictive health indicators, and automated service triage models
• Manage product line profitability (P&L optimization), pricing strategies, and packaging frameworks as the portfolio shifts toward virtualized, cloud-native subscription and SaaS delivery models
• Conduct market analysis to evaluate the Total Addressable Market (TAM), competitive landscapes (including independent software vendors and network equipment providers), and emerging operator pain points
• Support high-value pre-sales activities, delivering technical portfolio briefings, leading proof-of-concept (PoC) scopes, and responding to complex RFI/RFP requirements for major global carriers

Requirements:

• Mastery of 4G Evolved Packet Core (EPC) and 5G Standalone (5G SA) architectures, including comprehensive familiarity with network functions like AMF, SMF, UPF, NSSF, and NWDAF
• Deep understanding of mobile core protocol stacks (HTTP/2, GTPv2, Diameter, SIP/IMS) and real-time capture infrastructure (DPI, virtual taps, eBPF telemetry)
• Working familiarity with cloud-native deployment patterns (Kubernetes, AWS/Azure telco clouds), containerized applications, and distributed high-scale data architectures (Kafka, ClickHouse)
• Familiarity with 3GPP performance management/trace specifications and TM Forum automation/service management frameworks
• Minimum of 8 to 10 years of experience as a technical Product Manager, PLM, or Solution Architect in the telecom OSS/BSS, monitoring, or service assurance space
• Demonstrated experience managing software product pricing, constructing software subscription models, and generating business cases for major technology shifts
• Proven capability to influence across boundaries, collaborating effectively with software developers, system architects, finance, product marketing, and executive leadership
• Exceptional ability to synthesize highly complex, low-level technical infrastructure challenges into clear value propositions for executive-level (C-suite) operator decision-makers
