About the Role

We are seeking a Design Engineer to transform complex AI safety workflows into user-friendly interfaces for engineering and research teams. This role involves working with both design and code, from creating flows in Figma to implementing them with React and TypeScript.

Responsibilities

  • Design and build product interfaces end to end, from Figma exploration to production-ready React code
  • Own our design system in both Figma and code: tokens, components, variants, documentation. Keep the two in sync
  • Build and polish UI components with attention to states, edge cases, accessibility, and performance
  • Prototype interactions and new flows in code to test ideas with real data before we commit to them
  • Craft motion and micro-interactions that make complex workflows feel clear and responsive
  • Raise the quality bar of the product: spot UI inconsistencies, fix them yourself, ship
  • Work directly with product, engineering, and research. Expect fast iterations and full ownership

Requirements

  • 6+ years of experience in product design, frontend engineering, or design engineering, with a portfolio showing both design and shipped code
  • Strong frontend skills: React, TypeScript, modern CSS (Flexbox, Grid, custom properties, container queries)
  • Experience building and maintaining design systems in code, e.g. design tokens, component APIs, Storybook or similar
  • Deep Figma knowledge: Auto Layout, Components, Variants, Variables, Prototyping
  • Experience with motion and animation in code (Framer Motion / Motion, CSS transitions, or similar)
  • A track record of designing clear, functional web interfaces, ideally for technical or data-heavy products (dashboards, developer tools, B2B SaaS)
  • Solid grasp of accessibility (WCAG, keyboard navigation, ARIA) and responsive design
  • Comfort working in a real codebase: Git, code review, working alongside engineers
  • You use AI tools daily in your workflow (Cursor, Claude Code, v0, or similar) and know how to get production-quality results out of them

About the Company

  • White Circle is an AI Safety company building the safety, reliability, and optimization layer for AI systems.
  • At the core of our platform are policies – simple natural-language rules that define what an AI model should and shouldn’t do.
  • We automatically test, enforce, and continuously improve these policies at scale.
  • We’ve recently raised our Series A funding round, taking our total funding to $70M.
  • Our investors include top funds, founders, and senior leaders at OpenAI, Anthropic, HuggingFace, Mistral, DeepMind, Datadog, Sentry, and others
  • We process over one hundred million API calls every month
  • We fine-tune and train our own LLMs so they run faster and cheaper than any open or proprietary model
  • We’re a small, highly focused team. If you want to work deeply on hard problems, see your work ship to production quickly, and influence how AI safety is actually built – you’re the one we need
