Tasks

What you'll do

• Translate needs into scoped work – convert customer gaps, engineering ideas, and market signals into clear, acceptance‑ready backlog Jira tickets.
• Own backlog health – maintain ticket quality, sizing data, and priority suggestions so the VPofProduct can make informed roadmap decisions.
• Steer delivery flow – track progress, flag risks, and ensure documentation and release notes stay synced with shipped features.
• Capture and loop feedback – turn launch lessons and in‑field insights into follow‑up improvements, measuring adoption and impact.
• Monitor metrics that matter – cycle‑time, readiness ratio, release accuracy, and feature usage.
• Stay ahead of standards – watch 3GPP / GSMA releases and industry moves; highlight implications for future planning.
