Duties & Responsibilities:
VIAVI Solutions is seeking a strategic and highly technical Product Line Manager (PLM) to join our Automated Mobility Solutions (AMS) business unit, specifically owning the evolution of the NITRO Mobile product portfolio.
In this role, you will drive the product strategy, roadmap, and commercial success of our next-generation Mobile Core Service Assurance solutions. You will blend deep cellular network domain expertise (4G EPC, 5G NSA, and 5G Standalone Service-Based Architecture) with robust software product management practices. This position bridges engineering, data science, marketing, and sales to deliver cloud-native observability, automated root-cause analysis (RCA), and AI-driven insights (AIOps) to global Tier-1 Communication Service Providers (CSPs).
What you'll be doing:
Portfolio Strategy & Lifecycle Management
· 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.
Product Architecture & Technical Definition
· 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.
Business & Market Success
· 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.
Pre-Requisites / Skills / Experience Requirements:
What you'll bring to the role:
· Cellular Core Architecture: 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.
· Protocols & Telemetry: Deep understanding of mobile core protocol stacks (HTTP/2, GTPv2, Diameter, SIP/IMS) and real-time capture infrastructure (DPI, virtual taps, eBPF telemetry).
· Cloud & Modern Infrastructure: Working familiarity…
