Impart Security is seeking a UI/UX Engineer to design and build the Impart console, a runtime security platform protecting APIs, AI applications, and MCP servers.
You will transform dense, high-volume security data into clear, actionable interfaces including attack and request timelines, analytics dashboards, API and endpoint inventories, flow diagrams, and threat investigations. You'll own and evolve the design system and shared component library (data tables, filters, drawers, forms, charts, empty states) to enable fast, consistent feature shipping.
Key responsibilities include designing AI-native product experiences such as conversational rule generation, AI-assisted false-positive tuning, detection explanations, and suggested actions that keep humans in control. You'll craft power-user workflows for security engineers, including in-browser code editors for writing detection rules, keyboard shortcuts, bulk actions, and fast search and filtering over millions of requests.
You'll make emerging product areas (LLM and MCP security, bot protection, AI asset inventory) intuitive for teams encountering them for the first time. You'll use AI agents (e.g., Claude Code) as integral tools to prototype, explore design variations, and ship production code. You'll implement Playwright end-to-end and visual regression tests, unit tests, accessibility standards, and front-end performance optimization.
You'll partner with customers, product, and backend engineers to run user research, validate designs, and iterate based on real usage. You'll drive projects end-to-end: research, design, build, test, deploy, measure, and iterate. You'll contribute to an engineering culture of curiosity, rigor, and craftsmanship. In-person presence in San Francisco is preferred.
REQUIREMENTS:
- 2–6 years of experience designing and building production web applications, with a portfolio demonstrating both UX/visual design and front-end implementation
- Strong proficiency in React and TypeScript, with deep understanding of modern CSS, component architecture, and state and data-fetching patterns
- Fluency in Figma (or similar) and track record of taking features from user research and wireframes through polished, shipped implementation
- Experience designing data-dense interfaces for technical users (dashboards, complex tables, charts, graph or node-based visualizations)
- Solid grasp of interaction design, information architecture, accessibility, and visual design fundamentals
- Comfortable using AI and agentic tools to move fast
- Excellent collaboration and communication skills; comfortable in fast-moving, low-ego engineering culture
NICE TO HAVE:
- Experience with Claude Code
- Experience with Chakra UI, Vite, Recharts, Monaco Editor, or React Flow
- Experience designing UX for LLM-powered features (conversational interfaces, streaming responses, human-in-the-loop approvals)
- Background in developer tools, security, observability, or infrastructure products
- Familiarity with HTTP/API concepts, OpenAPI, or web application security (OWASP Top 10s)
