Kapa makes technical knowledge instantly accessible through AI assistants. As a research engineer you will work on improving Kapa’s ability to answer harder and harder technical questions. Check out Docker’s documentation ([https://docs.docker.com](https://docs.docker.com/)) for a live example of what Kapa is (look for the “Ask AI” button).
**The following challenges should excite you:**
* Evaluating a RAG system in production without labelled data.
* Creating your own benchmark from scratch.
* Building an agentic retrieval system that can judge when to be fast and when to take more time.
* Fine tuning embeddings or rerank models.
**To solve these challenges you will:**
* Work directly with the founding team and our software engineers.
* Keep up with the latest developments in the space and see how they can be applied.
* Design and run experiments.
**You may be a good fit if you have:**
* A Master's/ PhD degree in Computer Science, Machine Learning, Mathematics, Statistics or a related field.
* A detailed understanding of machine learning, deep learning (including LLMs) and natural language processing.
* Hands-on experience in training, fine-tuning and deploying large language models.
* Have prior experience working with vector databases, search indices, or other data stores for search and retrieval use cases.
* Significant experience building evaluation systems for LLMs or search.
* Familiarity with various information retrieval techniques, such as lexical search and dense vector search.
* The ability to work effectively in a fast in a environment where things are sometimes loosely defined.
* Want to learn more about machine learning research.
\* This is neither an exhaustive nor necessary set of attributes. Even if none of these apply to you, but you believe you will contribute to kapa.ai, please reach out.
