At Juo, were building technology for businesses that want to build, run and scale their subscription offering. Business model-wise, Juo is a B2B SaaS.

Our initial and current focus has been on direct-to-consumer ecommerce brands selling physical products, but our goal is to make Juo components applicable in any industry where a subscription model can be applied for repetitive selling of physical goods.

Juo operates at the intersection of a few areas, like ecommerce and payments, but — especially the new platform — with a strong focus on developer experience. The team is lean and consists only of experienced people. In the past, we built successful businesses together. Some unsuccessful ones too — and learned a ton from that.

Business-wise, we have passed the most difficult stage for any startup — finding the so-called product‑market fit, which means we can focus on building and perfecting the product without financial concerns about the purpose of these actions. We are confident in ourselves, in what we do, and in the value we create for ourselves, our clients, and end users.

Were backed by fantastic investors (MOC, Peak, Kogito, SMOK) and advisors, including domain experts from companies such as PayU, Piwik PRO, and Your KAYA. Weve just raised our third financing round. In other words, we have all the resources needed to be able to focus on building the product, shipping fast, and delivering value to the clients.

The role: Design Engineer

Why this role

Juo operates at the intersection of ecommerce, payments and developer tools. The product we built combines intuitive, modern UI / design with high quality performance.

We search for an experienced individual who is engineer by heart but at the same time has a strong visual taste. Someone that knows what will work and what won’t. Someone who can pick up any product‑related problem and solve it. A professional that can quickly understand the vision and execute upon it.

You’ll collaborate across teams to deliver features that solve real customer problems, while fostering a culture of technical excellence and innovation in a lean startup setting.
