Senior Ruby on Rails Developer

BuyBay (Amsterdam NH, Nederland) 26 dagen geleden gepost

At BuyBay, we're in the business of helping e-tailers, manufacturers and distributors resell their return products to new owners. With our own, in-house developed smart software and an end-to-end logistical chain we make sure return products keep their value and find their way to happy customers.

Our mission
We didn't start BuyBay because we saw a return problem. We saw an environmental problem. That's why we're determined to work hard and have a positive impact on the world around us. We don't want to shift the return-problem somewhere else: we really want to solve it. Because we're convinced we can. We work together with a tight knit network of brands, manufacturers, (e)retailers and (online) platforms. All with one goal: finding a return product a new owner as fast as possible and for the right value.

Because, why buy something brand new if there is also a - just as good - returned alternative? By giving return products a second chance, instead of writing them off, we prevent waste and contribute to a more sustainable and circulair environment. That's how we make a positive impact. Open, transparent and no-nonsense.

The development team takes care of the development, maintenance and support of the software BuyBay runs on.
