Upway | Software Engineers (All levels), Senior Product Designer, Senior Product Managers | Full-time | Paris (ONSITE)

We’re building the biggest bike shop in the world.

Upway is the leading marketplace for refurbished e-bikes across Europe and the United States.

In 3 years, we grew from 0 to $200M GMV. The tech team grew from a small senior core to ~12 engineers in 2025, and we plan to grow to ~30 engineers in 2026.

We also raised a $60M Series C at the end of last year to support the next phase of the company.

This is not a SaaS. We operate warehouses, handle real inventory, and build software that connects logistics, product, and marketplace dynamics at scale.

We work with a Shape Up–inspired methodology that gives teams real ownership: shaping problems, building solutions, shipping, and learning from real-world impact.
