In this role you will focus on Autograder research, training and adoption.
Collaborate with AI feature teams, eval design teams, and annotation teams to refine feature requirements, grading rubrics and gold annotation sets.
Develop, evaluate, and iterate on grading prompts to align autograder behavior with grading rubrics and the gold sets.
Identify when prompt tuning reaches its limits and apply other advanced techniques such as fine-tuning to close remaining grading accuracy gaps.
Design insightful analysis to measure and explain Autograder quality.
Collaborate with MLEs and feature teams on autograder deployment and adoption.
Develop scalable system to speed up autograder training processes.
Minimum Qualifications
Master's or PhD in Computer Science, Machine Learning, Artificial Intelligence, or a related field.
Deep understanding of visual-language models.
Familiarity with image quality assessment - perceptual quality dimensions, evaluation metrics, and rubric design.
Proficiency in Python; capable of writing well-structured, production-ready model code.
Strong communication skills in explaining autograder quality and driving autograder adoption with partner teams.
Preferred Qualifications
1+ years of industry experience in building VLM-based products.
Familiarity with autograder and evaluator-specific concepts: grading accuracy, agreement with human raters, calibration, and rubric design.
Strong expertise in prompt tuning and fine tuning for VLMs.
Demonstrated ability to read AI literature and translate it into applied autograder experiments.
Prior experience in building agentic system to scale autograder training/validation.
