Your role will be to optimize Zed's interaction with language models through rapid prototyping and rigorous evaluation. Using Python or another lightweight scripting language, you'll explore the frontier of model capabilities and validate approaches before we sink time into implementing production-grade features. You'll collaborate with the whole Zed team to envision new AI capabilities, then take ownership over the prompts, fine-tuning, and dataflow while Rust engineers focus on editor integration.

This role offers a unique opportunity to combine your AI expertise with a team that excels at crafting world-class user interfaces for code. At Zed, if you can envision an AI-powered coding interface, our team can bring it to life. Your innovations will push the boundaries of what's possible in code editing, transforming how developers interact with AI in their daily work.
