Back-end Engineer

About Us

Circularity for everyone! We are on a mission to help people recover the value embedded in their pre‑owned goods, transforming them into currency, and enabling brands to sell more sustainably. We’ve built a unique AI‑powered, product‑centric platform that connects retailers, consumers, and professional used‑goods buyers. As we scale rapidly across Europe, we’re raising the bar for sustainability in one of the largest markets worldwide.

Our Culture

We foster autonomy within our team, driven by our mission and the belief that 'culture eats strategy for breakfast.' In our view, agile management, long‑term planning, and a deductive approach often fall short—only execution and tangible results truly matter. We believe in shared ownership of the company and learning through experimentation.

Our Team

We are highly focussed on people and work relentlessly to put the best possible team together. Veliuers have workd in some of the best startups worldwide: Senso, Meta, Scalapay, Palantir, Qonto, ScaleAi, Satispay, TaxFix and more!

We secured our 4m USD pre‑seed round in July 2025 and we have giga office in Milan (Italy).
