About Pinetree
Pinetree is a frontier lab focused on transforming general intelligence into reliable labor. We build autonomous, long-horizon Computer Use Agents, which we believe is the first step towards achieving AGI.
Role Overview
We are looking for a Machine Learning Researcher to work on core research problems in agentic systems, multimodal models, and learning under real-world constraints. This role is research-driven but tightly coupled to deployment. You will design, prototype, and evaluate novel ML methods that enable reliable computer use, long-horizon reasoning, and robust interaction with complex interfaces.
This is an ideal role for someone who enjoys working on open research questions but wants their work to ship and matter.
Responsibilities
Conduct research on agentic ML systems, including planning, reasoning, tool use, and long-horizon execution
Design and evaluate learning methods for computer use, including vision-language models, multimodal perception, and UI understanding
Develop benchmarks, datasets, and evaluation frameworks for agent reliability, robustness, and safety
Experiment with fine-tuning, distillation, and reinforcement learning for real-world task execution
Analyze agent failures and propose principled fixes grounded in theory and empirical results
Collaborate closely with engineers to translate research ideas into production systems
Author internal research reports and, when appropriate, external publications
Required Qualifications
Strong background in machine learning, AI, or a related field
Ability to design rigorous experiments and analyze results critically
Comfortable working in fast-moving, ambiguous problem spaces
Preferred Qualifications
PhD or industry research experience in agents, robotics, HCI, or applied ML
Familiarity with browser automation, web agents, or UI interaction models
Publications in NeurIPS / ICLR / ICML / ACL / EMNLP or other respected conferences or journals
What We Offer
Opportunity to work on foundational problems in real-world AI agents
Direct ownership over research direction and impact
Close collaboration with a highly technical founding team
A culture that values rigor, clarity, and shipping real systems
About the Company
Pinetree Research is an AI research lab building the next generation of autonomous AI agents that can reliably use computers, software interfaces, and enterprise systems to complete real work. While today’s AI models excel at reasoning and language, most struggle to act within complex, GUI driven environments. Pinetree Research focuses on closing that gap by enabling AI to move from intelligence to execution.
Our core mission is to make computer use a first class capability of artificial intelligence. We develop AI systems ...
