Together with partners from science and technology, we are implementing an intelligent control and billing system for the e-mobility sector. In order to successfully develop our innovative product JustOn for E-Mobility, we are looking for you as requirement engineer.

Your skills are in the areas of analysis and planning. First, you collect and formulate product requirements, which you then communicate to our developers so that they can implement them. After the training period, you will take on responsibility as a product manager or product owner in challenging projects.


  • Collect, analyse, specify and validate product requirements
  • Managing, planning and implementing challenging sub-projects
  • Advising interested parties, new and existing customers in the areas of billing, invoicing, accounting and control of charging processes
  • Conducting business process analyses and developing specific solutions


  • Interest in digital business models, e-mobility, e-commerce and e-invoicing
  • Professional experience in consulting and business process analysis
  • Initial experience as project manager in the software sector
  • Problem-solving skills, negotiation and organisational skills as well as strong communication skills


JustOn stands for the successful automation of financial processes. As leading software providers on the Salesforce platform, we support companies in digitising their processes around billing, payment and accounting. The industry solution JustOn for E-Mobility is especially suitable for the billing of e-charging stations.
With our innovative software products, medium-sized companies around the world monetize every business model directly, including well-known customers such as Delivery Hero, Christie’s, and Verizon Media.
As company, we assume social responsibility. We preserve existing jobs and create new ones, we support social as well as other charitable projects, and we are committed to environmental protection.


With us, every second Friday is free – with full pay. This working time model corresponds to our guiding principle of new work: arrange your working life to suit your life situation. At JustOn, that’s exactly what we mean and live by.
Whether you work in our beautiful office with high-quality equipment or from home is up to you. After an onboarding phase, during which the team would like to get to know you personally, the working location is flexible.
Further training and personal development are not a phrase for us: Two days of educational leave and a fixed budget of 1500€ per year are available to every employee.
In addition, you’ll also find a cheerful, motivated team, competitive compensation and a family-friendly and appreciative environment with very short decision-making paths.
