Senior Compiler Engineer
Own a compilation surface end-to-end — parser, IR, codegen, diagnostics, tests. Ship code that runs in people's terminals every day.
What you'll do
- Extend the Axint IR to cover new App Intents, App Entities, or WidgetKit features
- Author new AX diagnostic codes and write the fix-it paths for them
- Keep generated Swift correct against real xcodebuild runs
- Review compiler PRs from the community
Must have
- Shipped a compiler, type-checker, or serious static analysis tool in production
- Comfortable in TypeScript and Swift — enough to read and critique both
- Writes code the way you'd see it at Apple, Stripe, or Vercel — small, obvious, tested
Nice to have
- Contributed to swift-syntax, tree-sitter, Babel, or any mainstream compiler
- Has opinions about IR design vs. direct codegen
- Has shipped a real App Intent or Widget
