About the Role
We are looking for an experienced JavaScript/TypeScript Developer with strong hands-on expertise in modern JS/TS ecosystems, including Node.js or full-stack development. In this role, you will validate asynchronous patches, execute complex test suites, identify root causes of failures, and ensure code correctness through precise debugging and thorough reasoning about async flows and event-loop behavior. You will work across real-world repositories, review PRs, and ensure that all changes meet quality, maintainability, and reliability standards.
Key Responsibilities
- Validate patches involving async/await, promises, callbacks, and event-loopdependent behavior.
- Execute and maintain JavaScript/TypeScript test suites using Jest/Mocha or similar frameworks.
- Diagnose failing tests, analyze stack traces, and debug issues in both frontend and backend JS/TS code.
- Review pull requests with focus on correctness, code clarity, consistency, and long-term maintainability.
- Understand and reason about event-loop mechanics, async timing, race conditions, and async workflows.
- ensuring correctness and maintainability in JavaScript/TypeScript systems.
- Assess changes for side effects, correctness of logic, and reliable behavior across modules/services.
- Collaborate with engineering teams to improve debugging processes, testing reliability, and overall code health.
Required skills& Experience
- 15 years of hands-on development with JavaScript or TypeScript.
- Experience working with Node.js, backend services, or full-stack JS/TS architectures.
- Strong proficiency with Jest/Mocha and modern JS test frameworks.
- Deep understanding of async/await, promises, microtasks/macrotasks, and event-loop internals.
- Ability to analyze runtime behavior and debug complex async scenarios.
- Proficiency in Git workflows, code review, debugging tools, and working with large repositories.
- Strong reasoning ability to evaluate correctness, side effects, and maintainability of patches.
- Experience handling async logic, debugging in both Node.js and browser environments, working with large codebases, reviewing PRs, running extensive test suites.
