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

- 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)
