Ruby on Rails Developer

About the product:

AndonCloud is a SaaS system for factories that combines Andon, MES, CMMS, HMI, and BI functionality. It enables real-time production monitoring, as well as management of orders, workstations, machine statuses, KPIs, and reports.

About us:
We are building our own product — we are not a software house. We are a small team with a short path from idea to implementation. Your technical decisions have a real impact on the product and on the everyday work of people in factories. We do not focus on years of experience; what matters is being capable, proactive, and able to solve problems independently.
