  • Work in an open and collaborative environment within the global Reply network and build next-generation AI applications and intelligent digital products
  • Collaboration with interdisciplinary teams including AI engineers, software developers and data scientists across industries such as Banking, Insurance, Automotive and Retail
  • A very active social program including paid training, conferences, communities of practice, hackathons and Reply XChange
  • Monetary Benefits include: Mobility package, Gym subsidy & WellPass, Insurance & Pension Scheme, Corporate Savings Plan, KiTa and Childcare Allowance
  • Flexible work arrangement between home office, EU-wide workation options, on site office-work in our downtown Munich office with access to Stammstrecke, and client on site visits

Requirements

  • Degree in Computer Science, Software Engineering, Data Science or a comparable technical field
  • Convincing communication and presentation skills in German and English in order to participate in workshops of both languages
  • Strong programming skills in Python and modern backend frameworks
  • Experience building applications using AI, machine learning or generative AI technologies
  • Familiarity with Retrieval-Augmented Generation (RAG) and vector databases
  • Familiarity with cloud platforms such as AWS, Azure or GCP
  • Engaging directly with enterprise clients to understand their business challenges and identify high-impact opportunities for AI-driven solutions

Nice to have

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
