Description

Requirements

- JavaScript experience, with TypeScript exposure and React fundamentals
- SQL and relational databases (MySQL)
- Ability to write unit tests with PHPUnit
- Git fluency for collaborative development (branches, PRs, conflict resolution)
- Ability to use agent tools such as Claude Code and explain AI-generated code
- Strong problem understanding mindset: ask for context and clarify before coding
- Fast, independent learning; comfortable asking for help
- Evidence of real working code (project, internship, practice, open source, etc.)
Benefits
- Real product work in a domain used by hundreds of companies and millions of end customers
- Early production deployments and ongoing learning via high-quality code review
- Paid AI tool licenses and paid equipment for work
- Supportive learning environment with direct access to leadership
