81 North is looking for a developer with strong TypeScript skills for a two-week project. The goal is to improve the type safety of an existing codebase by refactoring 'any' types, creating custom interfaces and types, and implementing stricter type checking. You will analyze the code, identify areas for improvement, and apply advanced TypeScript features to make the application more robust and maintainable. This project is perfect for a developer who is passionate about static typing and enjoys enhancing code quality. A solid understanding of TypeScript is a must.

This project is a concentrated effort to enhance the quality and reliability of a large TypeScript codebase. The application has grown over time, and several areas use loose type definitions (any) or lack proper type coverage. Your role is to act as a TypeScript specialist, improving the overall type safety of the project.

Key Tasks:

• Audit the codebase to identify all instances of the any type and other type-related issues.
• Replace any with specific, accurate types. This will involve creating new interfaces, enums, and custom utility types.
• Refactor functions and components to have explicit parameter and return types.
• Leverage advanced TypeScript features like generics, mapped types, and conditional types to create flexible and reusable type definitions.
• Work with complex data structures from APIs and ensure they are properly typed.
• Enable and configure stricter TypeScript compiler options in the tsconfig.json file to enforce better coding practices.
• Ensure the application compiles without errors and that all functionalities work as expected after the refactoring.

This is an ideal role for a developer who finds satisfaction in clean code and robust systems. You will need a deep understanding of TypeScript's type system and the ability to apply it pragmatically in a real-world application. This project offers a great opportunity to showcase your expertise in TypeScript and make a significant, immediate impact on a development team's productivity and code quality.

• At least 1 year of hands-on experience with TypeScript.
• Strong understanding of TypeScript's type system, including generics and utility types.
• Experience working on a large codebase.
• Familiarity with configuring tsconfig.json.
• Meticulous attention to detail.

• Deepen your expertise in advanced TypeScript features.
• Make a direct and measurable impact on code quality.
• Short, focused project with a clear objective.
• Work remotely with a high degree of autonomy.
