Job technologies

Your role in the team

  • Product Architecture & AWS Infrastructure: Contribute to the design and build a scalable cloud architecture on AWS for the ELMI-AI platform.
  • From MVP to production readiness: Evaluation, further development, and partial rebuild of existing module prototypes into a stable first production version.
  • EMS data integration: Connecting and processing data from the energy management systems of our charging stations and battery storage systems.
  • Dynamic pricing: Technical implementation of market analysis of nearby charging stations and automated, dynamic price adjustments.
  • Charging strategy optimization: Development of logic and algorithms to optimize the recharging strategy of internal battery storage systems.
  • Energy Trading: Technical implementation of interfaces and trading logic for automated energy trading.
  • Team collaboration: Close collaboration with the development team (including the nearshore team), including code reviews and contributing to technology decisions.
  • Hands-on Coding: Active development in the codebase, particularly during the critical build phase of the first stable version.

Our expectations of you

Qualifications

  • Hands-on mentality: You enjoy coding yourself and take ownership of your areas of responsibility from conception through to operations.
  • Pragmatism: You make technical decisions that fit the company’s current size instead of overengineering.
  • Language skills: Fluent German and very good English for collaborating with the international team. Knowledge of Mandarin is a big plus.

Experience

  • Experience: Several years of experience as a Software Engineer, ideally with experience building a software product from an early stage.
  • AWS & Cloud Architecture: Proven experience building and operating AWS infrastructure.
  • Platform/IoT experience: Experience with software that controls distributed physical assets (e.g., IoT platforms, fleet or asset management, smart grids). Experience with charging infrastructure, EMS, or energy trading is a plus, but not required.
  • Teamwork: Experience collaborating with (remote/nearshore) development teams; you enjoy sharing your knowledge with less experienced colleagues.

What we offer

  • Growth path: You’ll help build an entirely new business area with ELMI AI. As the product grows, so will your role and responsibilities, potentially leading to a Head-level position.
  • Technically exciting environment: modern AWS cloud architecture, real-time data from the field, dynamic pricing models, and energy trading—one of the most technically exciting interfaces in the energy transition.
  • Real responsibility from day one: You decide on the architecture, tech stack, and how the development team is built.
  • Short decision-making paths: Close collaboration with executive management and product management—no corporate bureaucracy, no silos.
