Member of Technical Staff, Research
Save this role or tell us whether you want more jobs like it.
Overview
At Primitive Labs our mission is to make human behavior a first-class primitive of software development.
In this role, you will build the research systems behind our behavioral intelligence agents. Your work will span simulation architectures, memory systems, computational cognitive science, continual learning, and agent architectures. The goal is to improve how agents model human behavior, make decisions, and act across real product experiences. You will also help define our research program through papers, technical writing, open-source work, and conference talks.
Responsibilities
Own research directions from question to production.
Design experiments for agent behavior.
Build simulations of real user decision-making.
Develop behavioral-fidelity benchmarks.
Train and evaluate agents against human data.
Translate research findings into model, memory, and runtime improvements.
Publish papers, technical write-ups, and open-source work.
Qualifications
Led research in agents, ML, simulation, or cognitive science.
Design rigorous experiments.
Build the systems needed to test your ideas.
Work deeply with large models and agents.
Turn research into production systems.
Care about human behavior, not just task completion.
Benefits include medical, dental, and vision coverage, plus paid time off and vacation.
