Frontend Developer Intern

🏢 About SixSense

SixSense brings artificial intelligence to the semiconductor manufacturing industry. Process and quality engineers across global semiconductor fabs and OSATs use the SixSense platform to inspect microscopic defect images, train and deploy ML models, and act on visual intelligence without writing code.

🎯 The Role

As a Frontend Developer Intern at SixSense (5-month full-time remote internship), you will build real production features in the web control room that semiconductor quality engineers work in every day. Rather than working on toy sandbox projects, you will tackle interactive image manipulation challenges, state coordination for large datasets, and browser performance optimization.

🛠️ Tech Stack

• React & modern JavaScript (ES6+)
• TypeScript
• HTML Canvas & SVG visualization
• Web Workers & OffscreenCanvas
• Material UI (MUI) theming and style customization
• Testing: Jest & React Testing Library

💼 What You'll Do

• Build and maintain production frontend features using React, TypeScript, and MUI.
• Develop interactive image experiences on HTML Canvas, including smooth panning, sub-pixel zooming, and drawing bounding boxes.
• Work with large datasets of high-resolution wafer images, defect annotations, and model inference outputs while keeping the interface responsive.
• Leverage Web Workers and background threads to move heavy computation off the main browser thread.
• Profile rendering performance and troubleshoot frame drops, responsiveness, and memory usage.
• Write unit tests for UI components and business logic using Jest and React Testing Library.
• Participate in structured code reviews, architectural discussions, and engineering mentorship sessions.

✅ What You'll Need

• Strong JavaScript fundamentals, including closures, the event loop, Promises, and asynchronous programming.
• Hands-on development experience with React (hooks, state management, component composition, and render lifecycle).
• Good understanding of HTML, CSS, and browser rendering fundamentals.
• Solid analytical problem-solving skills and familiarity with basic data structures.
• At least one substantial project that you built and can explain in depth, including technical decisions and trade-offs.
• Full-time commitment on weekdays for the 5-month duration with a reliable computer and stable internet connection.

🌟 Nice to Have

• Hands-on experience with TypeScript.
• Experience with HTML Canvas or SVG for drawing, visualization, or interactive geometry.
• Familiarity with Web Workers, OffscreenCanvas, or client-side performance profiling.
• Experience with automated testing using Jest or React Testing Library.
• Experience using modern AI development tools (Cursor, Claude Code, Copilot) alongside strong manual code review skills.
