What Is a Junior Developer Expected to Know

Short answer

Junior developers are expected to write basic code, debug simple issues, and learn quickly. They are not expected to architect systems or work independently on complex features.

How it works

Employers look for familiarity with version control, a programming language, and collaborative tools. juniors should ask questions, accept feedback, and demonstrate growth.

Example

A junior front-end developer can implement a static page from a design, write unit tests, and open pull requests. They may need guidance on state management or performance optimization.

Why it matters

Clear expectations reduce anxiety for new hires. Knowing what is expected helps juniors focus on foundational skills rather than comparing themselves to seniors.
