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.
Requirements
Our ideal new colleague
* 5+ years product management in IMS / VoLTE / SIP / Diameter software.
* Fluent in 3GPP spec navigation and end‑to‑end IMS call flows.
* Able to interpret SIP/Diameter traces and skim YAML / JSON / Helm for scope clarity.
* Jira & Confluence power‑user with proven backlog ownership and ticket hygiene.
* Data‑driven prioritiser who balances urgency, effort, and strategic value.
* Sharp, concise communicator—comfortable with engineers and executives alike.
Nice to have
* Worked across the 2G, 3G, 4G or 5G telco networks (understanding Network Core functions in 4G/5G cores, IMS Design & Virtualized Network Design)
* Hands‑on involvement with Tier‑1 operator roll‑outs and acceptance testing.
* Working knowledge of Kubernetes / public‑cloud cost models.
* Built automated changelog or product‑analytics dashboards.
