About us
Committed to building the next generation of 100% software-based mobile networks, ng-voice is creating innovative mobile infrastructure solutions and making them accessible for operators and enterprises that want to deploy future-proof networks.
To support our exponential growth, we are looking for a Product Manager (m/f/d) to join our Hamburg office.
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 VP of Product 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.

Nice to have
