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.
