PLC-Developer (m/f/d)


We pioneered the organic battery

CMBlu started in 2011 as a research-driven project with the goal of storing electrical energy in arbitrarily large quantities in an environmentally friendly, sustainable and cost-effective way. Since then, we have continuously expanded our broad IP portfolio and expertise in large-scale energy storage.

Today, we are one of the leading organic flow battery companies headquartered in Alzenau, 30 km from Frankfurt Airport. With our groundbreaking technology, we will drive the energy transition, together with our partners, customers and most importantly: with our employees!

We are a highly motivated, committed and fast growing team of over 140 employees. We are now preparing for the market launch of our products and further professionalizing our organization.

An important component of our batteries is the battery management system (BMS). The development of this software for control and regulation requires interdisciplinary cooperation with colleagues from specialist areas such as chemistry, hydraulics, electrical engineering, construction and testing. A high degree of discipline and initiative in implementation is a mandatory requirement. You can expect the opportunity to actively shape the area of software development.
