- frontend edge cases
- Work independently and asynchronously on your own schedule
Requirements
- Deep expertise in TypeScript (static typing, generics, interfaces, utility types)
- 3–5 years hands-on experience with modern frontend/full-stack frameworks such as React, Angular, Next.js, Nuxt.js, or Node.js
- Strong written communication to clearly explain technical decisions
- Detail-oriented and methodical approach to catching subtle errors and explaining why
- Bachelor’s degree or higher in Computer Science (or related field) preferred
Nice to Have
- Experience with data annotation, model evaluation, or AI-assisted development workflows
- Familiarity with testing frameworks and type-safe API design patterns
