Full Job Description
Description

This role spans the full stack of AI development: from training and fine-tuning models, to building the systems that serve them, to crafting the interfaces that let people experience them. You'll iterate rapidly and communicate what you've learned.

We value diverse experiences and unconventional paths-what matters is that you can build, learn, and communicate what you've discovered. We're looking for someone who brings something we don't already have, whether that's a novel technical specialty, an unusual background, or a way of thinking we haven't encountered. If you build things to understand them, we want to hear from you.

Minimum Qualifications

Experience training or fine-tuning ML models (PyTorch, JAX, or MLX)

Strong understanding of ML fundamentals: model architectures, training dynamics, evaluation

Familiarity with current ML research landscape

Experience reading and implementing techniques from ML papers

Proficiency in Python and Swift; experience with C++ or Rust a plus

Track record of building complete, working systems rather than isolated components

Preferred Qualifications

Experience with LLMs: prompting, fine-tuning, RLHF, inference optimization

Experience reproducing results from ML papers

Familiarity with Apple platforms and frameworks (CoreML, Metal, SwiftUI)

Experience building native apps for iOS or macOS

Background in an R&D, research, or prototyping environment

Ability to work on ambiguous problems where the goal is learning, not shipping

Bias toward building-you'd rather make something to test an idea than debate it

Initiative to pursue ideas without waiting for direction

Eye for detail and craft in how you present work

Comfort communicating ML research to diverse technical audiences

Experience presenting at or attending ML conferences (NeurIPS, ICML, etc.)

Interest in AI education or open-source community building

Work you can share: models you have trained, systems you have built, ideas you have explored
