Senior Software Engineer

• Build production web applications with React and TypeScript, with strong performance, accessibility, and testing
• Design AI-native interfaces: streaming responses, tool-call and agent-step visibility, approval and human-in-the-loop controls, citations, and graceful failure states
• Build and maintain a shared component library and design system
• Write the backend-for-frontend layer in Python or Node: APIs, auth, session handling, and streaming endpoints (SSE/WebSockets)
• Instrument user-facing AI features with analytics, tracing, and feedback capture to improve quality
• Use AI coding tools and agents to speed up UI development, testing, and review, and help the team do the same
• Review code, set frontend standards, and mentor engineers

• 4+ years of professional software engineering with a frontend-leaning full-stack record
• Strong JavaScript/TypeScript and React (Next.js or similar), with solid HTML/CSS and browser fundamentals
• 1+ year building UI for LLM or agent features that reached production (streaming, chat or workflow UIs, state handling)
• Working backend ability in Python or Node, including REST/GraphQL APIs and a relational database
• Frontend testing and quality practice: unit, integration, end-to-end, and performance and accessibility checks
• Working knowledge of Docker, CI/CD, and one major cloud

• Experience building dashboards or analyst-style tools for security, healthcare, or compliance-driven products
• Familiarity with agent protocols and tooling such as MCP, and with how agents call tools
• Data visualization experience for complex, high-volume data
• Experience with design systems and Storybook
• Open-source contributions or public UI projects

Experience: 4+ years in software engineering, including 1+ year building AI-powered user experiences in production

• Ship production features end to end with high quality and accessibility
• Deliver an agent-driven workflow UI that users adopt, with measurable task-completion or time-saved gains
• Establish the team's patterns for AI interface states, human approval steps, and frontend evals

You'll have high ownership at an early-stage engineering site, direct exposure to leadership, and the chance to shape how security teams interact with AI agents.
