Data Science Researcher (part-time 25%)

Rubrik Rubrik · Enterprise · Israel · Engineering

Part-time Data Science Researcher (25%) for Rubrik's Data Research Team, focusing on Cyber Security. The role involves leading long-horizon, high-complexity research initiatives using State-of-the-Art methodologies, with an emphasis on LLMs and Advanced NLP. The researcher will design and prototype advanced LLM workflows (RAG, Agents, Fine-tuning) and act as a knowledge hub, translating academic concepts into functional Proofs of Concept (POCs). Requires current PhD enrollment in ML/NLP/AI, industry experience with real-world data, strong Python/ML framework skills, and LLM expertise beyond prompting.

What you'd actually do

  1. Lead specific, deep-dive research initiatives that require advanced methodology (e.g., novel anomaly detection architectures or LLM-based reasoning for security threats) without the pressure of daily sprint cycles.
  2. Design and prototype advanced LLM workflows (RAG, Agents, Fine-tuning) to solve specific security challenges that standard APIs cannot handle.
  3. Act as a knowledge hub for the team; bring SOTA academic concepts, recent paper findings, and novel techniques into the team’s toolkit.
  4. Build functional Proofs of Concept (POCs) that the full-time engineering team can eventually operationalize.
