Technical Product Owner

About 0TO9

0TO9 is a fast-growing, profitable European fintech bank built on a unique model: in parallel with our banking operations, we act as a venture builder — launching entrepreneur-driven portfolio companies with capital, licenses, and infrastructure from day one, each a different banking product or vertical. We build alongside a team of founders, colleagues, and investors who bring some of the strongest track records in banking and fintech.

About the role

As Technical Product Owner, you'll work at the heart of the infrastructure our portfolio companies run on. That covers Z9, the shared platform of vendors, tools and integrations used across the group, and our core banking system. You'll be the link between the portfolio companies, the bank and our technology partners, making sure needs are understood, prioritized and delivered. This is a hands-on role where you'll get real responsibility early, work closely with experienced founders and colleagues, and grow your ownership as we scale. What you'll do:

• Own and prioritize the backlog for Z9 and the core banking system

• Gather and structure needs from the portfolio companies, and turn them into clear requirements and user stories

• Work closely with engineers and vendors to drive delivery, from specification and testing to release

• Coordinate vendor onboarding and integrations, and follow up on performance and SLAs

• Keep documentation and the vendor overview up to date together with risk and compliance

About you

You're technically curious, structured, and eager to learn how banking works under the hood. You enjoy solving problems with many different people, and you're comfortable taking ownership in an environment where things move fast and structures are still being built. We'd expect you to bring:

• Experience as a Product Owner/Product Manager or similar background

• A solid understanding of APIs and system integrations

• Fluency in English and Swedish

• Experience with core banking, lending or payment systems is a plus

What we offer:

• Be part of building the leading fintech bank & venture builder

• A dynamic, entrepreneurial and international environment

• Beautiful office in the heart of Stockholm
