Job description

AI Researcher at Vetto who designs datasets, benchmarks, and evaluations to teach models new capabilities and measure whether training interventions worked. The role is evaluation-driven with some fine-tuning and post-training to validate research hypotheses, working directly with top AI labs.

What you'll do

Design and run experiments to understand model behavior, test new ideas, and determine whether a dataset or training intervention actually works.
Use fine-tuning and post-training experiments when useful to validate research hypotheses and measure improvements in the capabilities we care about.
Create datasets, benchmarks, agent environments, rubrics, and evaluation methods for problems that are not well measured today.
Work directly with AI labs and enterprise partners to turn open-ended model-development goals into concrete research and data projects.
Dig into model outputs and trajectories to understand systematic failure modes and separate model limitations from problems in the data, grader, or evaluation setup.
Write analysis code and build lightweight tools or prototypes for your own work, with support from engineers when a workflow needs to become reliable infrastructure.
Share what you learn through clear technical reports, internal discussions, benchmarks, and research papers.

What we're looking for

Experience doing empirical research or similarly open-ended technical work with machine learning systems.
Hands-on experience designing and running agentic systems for complex work, such as coding agents and automated research pipelines.
Good experimental judgment: you can form a hypothesis, choose useful baselines and metrics, run a careful experiment, and make sense of noisy results.
Strong Python and data analysis skills, plus enough software engineering ability to prototype your own research workflows.
The independence to take an ambiguous question about a model and turn it into a dataset, benchmark, experiment, or other concrete contribution.
Rigorous analytical thinking — you look at the underlying evidence, notice subtle failure modes, and question results that seem too simple or too good to be true.
Excellent written and verbal communication with researchers, engineers, customers, and non-specialists.
Comfort with ambiguity, fast iteration, changing priorities, and occasional forward-deployed work with partner teams.

Nice to have

Research or industry experience in LLM evaluation, post-training, agents, human or synthetic data, alignment, or AI safety.
Experience designing datasets or benchmarks, validating annotation quality, or working with large collections of model outputs and trajectories.
Published research, technical writing, open-source contributions, or strong independent projects.
Experience building or managing human feedback pipelines.
A background in cognitive science, linguistics, philosophy, statistics, or another field that helps you think clearly about evaluation.
Experience at an AI lab, AI data company, or in a partner-facing research role.

Benefits

Competitive compensation and a stock option plan.
Global, remote-first work with flexibility and periodic in-person on-sites every few months.
Direct collaboration with cutting-edge AI labs on evaluation, data, and post-training challenges.
High ownership and fast career growth in a founding-era team.
