Job description

You work in a TypeScript codebase that spans the UI, the API, or both, for a US team. The types have to match what the code does with real input, including the failure case. A type that only covers the happy path is not done.

What you do on the team

On a placement, this is the work the US team expects.

• Work in the TypeScript codebase, on the UI, the API, or both
• Make the types match real input, including the failure case
• Cover the change with the test runner in the repo
• Use AI tools to draft a typed function, then check the types against real inputs before it ships
• Review the pull request before it ships
• A type that only covers the happy path is not done

The stack

• TypeScript
• React, Node.js, or both
• Types at the API boundary
• The test runner in the repo
• The lint and build the team already runs

What we look for

• TypeScript in a production codebase
• Types that match the runtime, not only the happy path
• React, Node.js, or both
• 5 or more years as a software engineer
