Software Engineer (Frontend Focus)

You will build and ship the user-facing product that brings AI-driven insights into real engineering workflows. Your work will help customers explore predictions, compare results, and make faster decisions through clear, intuitive interfaces. This is a high-impact role where what you deliver becomes part of how world-class teams design, iterate, and tape out next-generation semiconductors.

​

​This role requires in-person work at our San Francisco or Taipei office.

Leafy Lab

Leafy Lab is redefining semiconductor design with explainable AI. Our technology aims to deliver 95%+ prediction accuracy and reduce chip development time by up to 50%. By combining AI, device physics, and semiconductor engineering, we build next-generation modeling and circuit design tools that address the industry’s hardest technical challenges. Our platform is trusted by the world’s top 10 chip design companies and backed by leading Silicon Valley investors. Every engineer directly shapes our product and the future of AI-driven chip design.

Key Responsibilities

  • Build interfaces for our AI platform (e.g., dashboards, prediction workflows, and data management)

  • Translate product requirements into intuitive UX for technical users (e.g., clear information hierarchy, fast iteration)

  • Work closely with backend and AI/ML teams to define APIs, data formats, and end-to-end user flows

  • Implement rich visualizations for model outputs, comparisons, and experiment history

  • Own features end to end from implementation to release, including quality, performance, and reliability

Qualifications

  • Bachelor’s degree in Computer Science or equivalent practical experience

  • 3+ years of software engineering experience focused on frontend development

  • Strong frontend skills and modern web frameworks (e.g., React)

  • Experience building data-heavy interfaces (tables, filters, charts, forms, state management)

  • Comfortable moving fast and taking ownership in a startup environment

Nice to Have

  • Experience with design systems and component libraries

  • Strong UI/UX instincts for complex technical products

  • Experience with frontend performance profiling and optimization

  • Familiarity with authentication, permissions, and multi-tenant web apps

  • Experience shipping products that integrate with complex third-party tools or workflows

Why Join Leafy Lab

  • Real Industry Impact: Build tools used by global engineering teams to accelerate next-generation AI and chip development

  • Deep Technical Challenges: Tackle complex ML × device physics × EDA problems, including high-precision modeling and explainable AI

  • Full-Stack Technical Growth: Develop across chip design, device modeling, AI algorithms, and system-level tooling

  • High Ownership and Influence: Early engineers shape our architecture, product direction, and long-term technical vision
