Your mission

Together with other Software Developers and a Product Owner your goal will be to make energy consumption in buildings transparent to their residents. This data has to be reported every two weeks at the legal minimum, and one of our big goals and challenges is to increase this frequency end-to-end.

  • You will become a member of Team Tetris, an engineering team at our sister-company KALO, building products in and around the energy consumption reporting domain.

  • You will work closely with other teams and departments at KALO, as well as with teams at Beyonnex, to ensure the products you build integrate well with both ecosystems.

  • Your focus will be on backend development

  • You will be involved in every part of the software engineering process and in the lifecycle of the services that your team is building - requirements, design, development, testing, deployment, maintenance, operations and improving software based on user feedback and usage metrics

  • you are motivated by end results, by features made available to the customer. You strive for simple solutions. Technology is your tool, not your goal.

  • Practical experience working in agile development teams

  • B2-level English, C1 preferred (Beyonnex is international and fully english)

  • willingness to travel to our offices in Hamburg, once a month

  • Curiosity and the ability to learn fast

  • Motivation to iteratively develop processes in our organization

  • Problem-solving mindset

Benefits are following skills and interests:

  • Knowledge of web-development using any modern frontend framework and TypeScript. The ability to help out in this area when needed will increase the team's flexibility.
