ABOUT THIS ROLE

Software Development at Rasa is not only about writing code.

• Contribute to good architectural designs, and quality code, and help break an ambitious long-term vision down into milestones and issues.

• Share and learn good software practices through code reviewing with your peers.

• Think lean, prototype ideas quickly ask the right questions, and move forward projects with uncertainties within the context of the team.

• Mentor junior developers and help them develop great software engineering skills.

• Navigate our tech stack: Python, LiteLLM, LangChain, vLLM, HuggingFace, Unsloth, Milvus, TensorFlow, Transformers, Dask, Redis, Postgres, GitHub Actions, Kubernetes among other technologies and frameworks.
