Your role in the team

  • As a Junior Java Developer with a focus on AI/ML, you work in a multidisciplinary Scrum team and develop technically demanding solutions for software applications in the areas of relationship management and product configuration.
  • With your work, you significantly contribute to making the sales process more efficient, error-free, and of higher quality through AI-powered automation.
  • Your activities include, for example, the development of AI-supported methods for the automated conversion of free-text requirements specifications into compliant product configurations in our Merlin CPQ system.
  • Another focus of your work is on AI-based assistance solutions, help chatbots with modeling knowledge, and personalized configuration recommendations.
  • To find the optimal approach, you systematically compare and evaluate your prototype implementations in terms of accuracy, robustness, and integration effort.
  • In doing so, you independently implement your concepts in the product, identify new application areas for AI features, and actively drive their further development.

Our expectations of you

Education

  • You hold a degree in a computer science-oriented program such as Applied Computer Science, Business Informatics, or Mathematics.

Qualifications

  • You have a good understanding of modern AI/ML techniques, especially in the areas of NLP & LLMs (e.g., fine-tuning, prompt engineering, RAG, evaluation metrics) as well as personalized recommendation systems and decision support.
  • You have solid knowledge of object-oriented development with Java and Python and enjoy working with modern technologies, frameworks, and tools.
  • You are driven to actively shape products and your work environment, to contribute to an agile team, and to share your knowledge with your team members.

Experience

  • You are familiar with the theoretical foundations of AI applications and have experience working with common tools such as LangChain, PyTorch, or scikit-learn.
  • Perhaps you already have experience with MCP, Agentic AI, or generative models (e.g., for document generation); this can be helpful in your tasks but is not a prerequisite.

What we offer

  • In addition to our we-culture and focus on healthy relationships, we also offer our co-creators a wide range of benefits.
  • Together, we shape your personal role based on your experience and skills.
  • Our CAS Academy offers a variety of further training opportunities.
  • We tailor the right offer for you, including coaching, training, expert, and leadership programs.
  • With us, you flexibly combine team days on-site and mobile office.
  • With FlexTime and FlexVacation, you can choose annually between 28 - 40 hours per week or vacation days.
  • Whether it's JobRad, Germany Ticket Job, or our CAS sports groups – take advantage of our offerings to make your everyday life healthy, active, and environmentally conscious!
  • In our company-owned restaurant "Culinarium," you recharge energy for the second half of the day.
  • Fresh fruit and beverages are also available to you free of charge.
  • We value collaboration highly.
  • Events like our summer party with the whole family, team barbecues, or networking in expert groups await you.
