As a Frontend Engineer, you will be responsible for the full lifecycle of frontend features. This includes writing testable code, participating in code reviews, and collaborating with designers to ensure high-fidelity implementation of UI components. You will frequently interact with backend engineers to define API contracts, ensuring seamless data flow between the server and the client.

You will also be expected to drive initiatives that improve developer productivity, such as refining component libraries or upgrading legacy code. Success in this role is measured by your ability to deliver robust features on time while maintaining a focus on accessibility and performance.

Candidates who excel in this role demonstrate a solid balance of technical expertise and soft skills.

• Must-have skills: Proficient in JavaScript (ES6+), React, and TypeScript. You must have a clear understanding of modern frontend build tools and version control systems like Git.
• Nice-to-have skills: Familiarity with automated testing frameworks (e.g., Jest, Cypress) and experience with state management libraries like Redux or Zustand.
• Experience level: Most candidates for this role have several years of professional experience in frontend-heavy environments, though the ability to articulate past project successes is more important than a specific number of years.
