About

Engineering without borders.
We believe great software is built when talented engineers come together around real
problems, regardless of geography. ONELITY exists to make that possible. We are a
European product-engineering company shaping a new model for how software is delivered
across Europe, smart-shoring built on partnership, transparency, and shared ownership.
Embedded engineering, true partnership.
Our mission is to be the trusted technical partner of Europe’s most ambitious organizations.
We integrate our engineers as full members of our clients’ product teams, building
cloud-native platforms, event-driven systems, and modern services. The software we deliver
supports real users at real scale, and our engineers are present in the room when the most
important architectural and product decisions are made.

Our way of working.
We operate with the discipline expected of a modern engineering organization: trunk-based
development, comprehensive automated testing, continuous deployment, and a culture of
open retrospectives. Cross-functional squads take end-to-end ownership of the products
they build, and technical decisions are made by the engineers closest to the work. We invest
deliberately in our people through structured mentorship, certified training in Agile, ISTQB,
and clear paths for advancement at every career stage. Rooted at the meeting point of
German engineering precision and Greek innovation, our culture is one of continuous
learning, mutual respect, and a genuine passion for craft.

Who we are & The Mission

Welcome to Onelity. We aren’t just another software house; we are a smart-shoring
partner engaging in high-value, long-term partnerships. We believe in a simple philosophy:
To know, to learn, to share.
Our culture is strictly flat. We don’t care about titles when we sit at the table; we care about
ideas, honesty, and mutual respect. If you love sharing knowledge and believe that “we” is
stronger than “I,” you’ll fit right in.
The Project: As a Product Owner, you will be the driving force behind a massive
modernization challenge for a major wholesale supplier serving time-sensitive clients (e.g.,
supermarkets, HORECA, hospitals, etc.) across Europe.
The Mission: We are building from scratch a robust, modular e-commerce platform. While
the core is in place, we are now entering the critical phase of building modules and 3rd
party integrations. Since you will be working directly with our partners in the DACH
region, very good command of the German language is essential for success in this
role. Your mission is to bridge the gap between business vision and technical execution,
ensuring we deliver a next-generation solution that transforms the food wholesale
industry.

we are not 100% remote nor 100% office-bound. You choose your mix. Want to
visit the office just 1-2 times a month on designated team days? That’s fine by us.
• Stability: We engage in long-term projects with steady, impactful work.
• The Culture: A laid-back, flat environment where you can speak your mind freely to
anyone in the company.

with business goals and timelines.
• Requirements Engineering: Define clear user stories, use cases, and acceptance
criteria for new modules.

• Collaboration: Strong interpersonal skills; you act as the “bridge” and know how to
foster collaboration between diverse teams.
• Passion for Impact: You want to work on cutting-edge e-commerce solutions that
have a real-world business impact across Europe.
