The Role

As our Product Manager/Owner, you will sit at the intersection of AI platform development and sustainable packaging innovation. You will own the product lifecycle end-to-end, from discovery and validation to delivery and adoption, ensuring our AI-driven platform delivers measurable business and sustainability impact for customers in the packaging value chain (material suppliers, converters, brands etc.)

You will report directly to our Co-founder and will work closely with Engineering, Data, Design, and Go-to-Market teams, translating real customer problems into scalable, high-impact product solutions.
This role requires end-to-end (design and execution) management and ownership of Product cycle. Further details below.

We are open to remote candidates within Europe (+/- 2hrs CET), with a preference for Spanish or German based candidates who can be directly employed. Any other locations would be managed through Employer of Record services.

  • AI Value Identification:Identify and prioritise opportunities where data, AI, and software can deliver the highest ROI, balancing customer impact, feasibility, and scalability.

  • Hypothesis-Driven Validation: Partner with Engineering to test assumptions through prototypes, experiments, and MVPs before committing significant development effort.
