Kotlin / Java Backend Engineer - Energy Tech / IoT (m/w/d), 1. image

CO2 emissions in the real estate sector must be reduced quickly. But what is not measured cannot be controlled in a targeted manner: Our live data on consumption and generation in properties enables the most effective use of electricity, gas, heat and water in everyday life.

We are a young Berlin scale-up that supports sustainability and also lives it in our day-to-day business. We are looking for a Backend Software Developer in Berlin or Heidelberg at the earliest possible date.

Responsibilities

  • You design and develop a distributed, reliable backend software platform for our in-house operations and data processing.
  • You drive the expansion of our platform's capabilities through strategic feature development and continuous improvement efforts, with a heavy focus on backend.
  • You define and enforce architectural and infrastructural standards, prioritizing robust and modern technologies while avoiding unnecessary tech trends.
  • You develop a deep understanding of complex business processes in the German energy market in order to work together with multiple stakeholders across all departments.
  • You reconcile specifications and strategy with external boundary conditions (e.g. product standards, operational constraints, market regulations).
  • You develop broad knowledge of capabilities and constraints across the German energy market, metiundo specifics, as well as integrated external systems.

Profile

  • You have a university degree in Computer Science, a related field or an equivalent qualification.
  • You have at least 3+ years of experience in programming in Kotlin or Java, including the spring framework and build systems such as gradle or maven.
  • It is an advantage if this is complemented with experience in golang and/or TypeScript and Vue.js.
  • You have experience in designing and optimizing relational database schemas, particularly PostgreSQL.
  • You are comfortable with Linux, working in a terminal and know how to use git and docker.
  • Fluency in written and spoken English is required, with German skills being desirable.
  • Bonus points: You worked with IoT or other hardware-in-the-loop systems before and gathered experience in the German energy market.

What we offer

  • A job that lays the foundations for using energy and water sustainably and consciously.
  • Permanent position with a fixed salary of between EUR 60 - 70 thousand.
  • Flexible trust-based working hours, part-time option, at least two days of mobile working per week, individual training plan and regular feedback meetings.
  • Germany ticket or job bike, as well as an office with very good public transport connections.
  • A green and dog-friendly office, terrace and free drinks.
  • Complete technical equipment.
  • 30 vacation days/year.
