We develop intelligent solutions that take our products and platforms to the next level through machine learning and AI-driven approaches. Our focus lies on building high-performance, scalable features for AI-powered automation and decision-making processes – integrated into our existing product portfolio and as building blocks for future cloud services.
As a Senior AI Developer, you will work at the intersection of traditional software engineering and cutting-edge AI research.

• Experience with evaluations of AI models and systems, including performance and quality assessments, would be beneficial.
• Familiarity with Agentic Frameworks such as LangChain, Semantic Kernel (SK), or similar technologies is advantageous.
• Experience with GenAI Gateway for managing and integrating generative AI models is considered a plus
• Excellent English communication skills (written and spoken).
