Product Owner

We are looking for a proactive and detail-oriented Product Owner who thrives working shoulder-to-shoulder with engineers and turns customer, market and stakeholder signal into clear priorities. In this role, you will sit inside a product engineering team, alongside the lead and product engineers, shaping problem statements, backlog and sprint plans that the whole team believes in. This is a full-time role based in Sofia, Bulgaria. We value in person collaboration and meet in the office at least 3 times a week. Some of the things you'll work on: Bring outside context into the team, including customer feedback, support trends, usage data and competitive landscape. Write clear, honest problem statements that a product engineer can pick up and run with. Track outcomes after a feature ships, not just whether it ships. Keep the backlog tidy and up to date in Jira, drafting new items and retiring stale ones. Draft problem statements and acceptance criteria for new tickets, finishing acceptance criteria jointly with a product engineer where needed. Run backlog grooming as a working session with product engineers. Bring a clear "why it matters" into sprint planning and set the sprint goal together with the lead and product engineers. Surface new signal that could shift priorities and work through trade-offs before committing to changes mid-sprint. Shape and sequence the roadmap together with the lead and engineers, and own the "what problem is worth solving" call. Join sprint reviews and demos to check delivered work against the original problem. We're excited if you have: 3+ years of experience as a Product Owner, Product Manager or similar role, with real day-to-day ownership of a backlog. Hands-on experience running Jira, including writing tickets and running or co-running grooming sessions. Comfort working shoulder-to-shoulder with engineers rather than handing off finished specs. Strong plain-language writing skills for problem statements and acceptance criteria. Enough technical fluency to follow a trade-off conversation and ask the right questions. A track record of prioritising under pressure, including saying no and explaining why. Genuine curiosity about the "why" behind customer and business problems. Familiarity with tools like Notion, Mixpanel or Amplitude for tracking outcomes post-launch. Some direct customer-facing experience, such as support, sales engineering, customer success or research.

Why you'll love it here: Flexible working hours and home-office (2x per week) Internal shares programme (EDPP) Ergonomic workspace and cutting-edge technology Regular team events Modern and stylish offices Sustainable merch for all employees Adverity Social Responsibility Days (+2 days paid off)
