  • Sunhat bridges this "Proof Gap". We are the Collaborative Proof Platform that consolidates scattered data into a central, verified Proof Library.
  • As an AI Software Engineer (m/f/d), you will work on innovative projects in the areas of text generation, text classification, semantic search, and agentic AI workflows.
  • Your responsibilities include evaluating LLMs, integrating them into our platform, orchestrating AI agents, and optimizing performance with regard to scalability and efficiency. You will work closely with software engineers and sustainability experts, leveraging your expertise to seamlessly incorporate machine learning and AI-powered features into our software solution.
  • Drive generative and agentic AI initiatives from ideation to deployment, ensuring that solutions are robust, scalable, and seamlessly integrated into our platform.
  • Work on tasks using generative AI and natural language processing such as text generation with agentic RAG, semantic similarity, and classification, leveraging current AI models.
  • Work closely with Software Engineers to integrate GenAI models and agentic workflows directly into our platform, focusing on efficiency, security, and performance at scale.
  • Utilize modern LLMOps practices and TDD (Test-Driven Development) to ensure reliable, maintainable pipelines and to enable rapid iteration and deployment of models.
  • Collaborate with product management, sustainability experts, and the engineering team to translate business requirements into powerful, AI-driven features that enhance the capabilities and user-friendliness of our product.
