Intern Frontend Engineer

We are a small frontend team building a web platform for ML data annotation. Our frontend work is an active balance of greenfield feature development and the continuous evolution of our established data-annotation tools. Whether architecting a new visual editor from scratch or modernizing an existing codebase, we hold all work to the same standard: architecture docs as the source of truth, small reviewed PRs, strict linting/type checks a dedicated component book for every UI element, and an AI-assisted workflow.

We are looking for an intern with solid TypeScript fundamentals who is eager to learn Svelte and modern frontend conventions. In this role you'll start with well-scoped tasks: UI components, component book entries, tests, small bug fixes in legacy projects under a mentor's review, and grow toward owning small features end to end. You will work with a modern stack (Svelte 5, TypeScript, Tailwind, Bun), practice AI-assisted development as a standard workflow, and ship to production behind strict quality gates in a team small enough for your work to make an immediate impact.

• →Implement small UI components and pages in Svelte 5 / TypeScript following the design system
• →Add component book entries and write unit/browser tests for new and existing components
• →Fix well-scoped bugs in the new platform and in legacy projects
• →Integrate simple REST endpoints under guidance
• →Participate in code review (receive feedback, and gradually review others' PRs)
• →Keep type checks, lint and tests green on your changes
• →Improve documentation and conventions where you find gaps
• →Learn and apply AI-assisted development responsibly

• At least 1 year of experience and/or a GitHub profile with pet projects available for the team review 
• Solid TypeScript fundamentals
• HTML/CSS knowledge
• Familiarity with at least one modern frontend framework (any — Svelte, React, Vue)
• Good understanding of client-server communication
• Git basics
• Ability to understand technical documentation and follow engineering guidelines
• Good written and spoken English (preferably B1+)

• Solid knowledge of Svelte/SvelteKit and Tailwind
