Lead Frontend Engineer

Role overview Build the systems that let a design team take work from an idea to production-ready code with fewer handoff gaps. Embedded in Design, you will define frontend standards, develop AI-supported workflows and tools, and help establish code as the reliable reference for product implementation. The role combines technical leadership with hands-on frontend development, design system work, and coaching designers who build with AI.

Responsibilities - Set and enforce standards for production-ready frontend work created within Design. - Build the tools, agents, and workflows that help Design, Product, and Engineering move work toward release. - Review designers’ code and provide guidance that improves quality and helps them learn. - Partner with design system colleagues on reusable components, tokens, and system improvements. - Create practical documentation, examples, and guardrails for AI-assisted design and development. - Add automation and checks to catch design system violations before review or release.

Requirements - At least seven years of frontend experience, including two or more years leading technical work, architecture, standards, and code review. - Hands-on experience building AI agents and workflows, including tool use, prompts, evaluation, guardrails, and integration into development processes. - Advanced daily use of AI coding tools and experience with capabilities such as hooks, subagents, or tool integrations. - Expert React and strict TypeScript skills; strong Tailwind CSS and component library experience. - Experience with design systems, token pipelines, theming, component APIs, and documentation tools. - Testing experience across unit, component, end-to-end, and visual regression; practical accessibility and internationalization knowledge. - Familiarity with performance profiling, frontend tooling, monorepos, CI workflows, Git, and fluent written and spoken English.

Nice to have - Electron or desktop application experience; deeper knowledge of accessibility or internationalization standards; internal developer tools, command-line tools, or code generation experience. - Background in SaaS, CRM, or creator-focused products, or Chinese or Spanish language skills.

Benefits and work setup - Flexible hours and a yearly company offsite. A relocation package may be available for moves to Spain; eligibility details are not specified.
