experimental design Jobs

OpenAI

As a researcher on Frontier Assurance, you will build the technical foundations for rigorous assessments of frontier AI risks. You will help design technical assessments with external evaluators and internal teams, identifying consequential safety claims to test, defining the evidence and methods needed to assess them, and addressing gaps in coverage. You will work closely with external evaluators and embedded auditors, helping them understand the systems they are assessing and access the models, data, and technical information their work requires. Where direct access is not possible, you will conduct experiments and analyses on their behalf, with methods and results they can meaningfully scrutinize. This role combines research engineering, experimental design, and close technical collaboration, moving between investigating specific safety questions, navigating complex internal systems, and building reusable tools that make assessments more thorough and efficient. Your work will help turn independent scrutiny into concrete evidence about model capabilities, safeguards, and remaining risks.

Replit

Replit is seeking a founding Data Scientist for its Growth team. This role will partner with Product and Engineering leadership to drive initiatives across acquisition, activation, and recommender systems. The ideal candidate is proactive, identifies opportunities, and influences product development with a strong point of view. You will own data science for major growth areas, design experiments and metrics to bridge short-term readouts with long-term outcomes, and help establish experimentation standards for high-traffic surfaces. The role also involves using quasi-experimental designs, defining data science for personalization and recommendations, modeling freemium economics, and developing user segmentation.
