Senior Product Manager (Remote)
Krakow, Kraków
Rimthan LAB
Role Purpose
The Senior Product Manager ensures that venture goals are translated into validated product outcomes across Rimthan’s portfolio. They are both a strategic partner (owning product vision, roadmap, and KPIs) and a hands-on contributor (supporting discovery, validation, and delivery). The PM balances customer needs, client objectives, business viability, and technical feasibility, ensuring Rimthan delivers world-class products with measurable business impact.
This is not a project management role. The focus is on defining and validating product outcomes, not managing timelines or task tracking.
The role reports directly to the CPO, Marcus Wiberg: https://www.linkedin.com/in/marcuswiberg/
