Product Manager (m/f/d)

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.

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.

Our ideal new colleague

• 3–5 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.

• 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.
