• Familiarity with the React ecosystem, including state management and component lifecycle.

• Some practical experience building services with Node.js is preferred.

• Ability to read, understand, and contribute to code in at least one core backend language, such as Go (Golang) or a JVM-based language (Java/Kotlin), or a strong willingness to learn these languages.

• Basic understanding of cloud environments (AWS is a plus).

• Experience with testing frameworks (e.g., Jest, React Testing Library).

• Working knowledge of relational databases (e.g., PostgreSQL, MySQL).

• Good problem-solving skills and a proactive attitude toward learning new technologies.

• Ability to work independently and as part of a team, with excellent communication skills.

• Intermediate to advanced English proficiency is required for effective communication.
