Responsibilities

Drive modeling and evaluation for Calendar intelligence features from problem framing through launch.
Define metrics, evaluation sets, baselines, and human-review processes before building models.
Find and use data effectively, including priors, shared structure, and self-supervision when data is limited.
Develop and evaluate large language models, smaller models trained from larger-model judgments, and heuristics across on-device and server environments.
Write production software across the stack and Apple platforms.
Design tool- and function-calling interfaces, construct model context, and validate model output.
Collaborate with ML, design, and product teams to establish shared interfaces and deliver features.
Drive ambiguous problems forward and align teams on shared API surfaces.

Requirements

Bachelor’s degree or foreign equivalent in Computer Science, EE, Applied Mathematics, or a related field, plus 2+ years of experience developing ML/AI-driven software.
Proficiency in one or more of Python, Swift, Objective-C, or C++.
Experience developing software prototypes and features driven by large language models, including tool and function-calling interfaces, context construction, and model-output validation.
Fluency with agentic coding tools such as Claude Code and sound judgment in applying and verifying them.
Experience driving ambiguous problems with cross-functional partners from an initial idea through launch.
Strong machine learning, probability, and statistics foundations with hands-on model training and evaluation experience in PyTorch or JAX.
Experience designing systems for resource-constrained environments with on-device latency, memory, and power budgets.
Experience designing evaluations involving metrics, held-out sets, baselines, and human judgment.
Exceptional problem-solving, communication, and cross-team alignment skills.
