About the role

Senior UI Engineer responsible for leading the next generation of the Distributed Spectrum product UI, architecting frontend, and delivering high-performance visualizations and integrated agentic capabilities.

Responsibilities

  • Drive the design and delivery of new product experiences, from concept through polished, shipped UI.
  • Lead the frontend architecture: application structure, state management, component libraries, design system, build tooling, testing strategy, and performance budgets.
  • Integrate the UI deeply with agentic services and streaming responses, tool-call visualization, human-in-the-loop approvals, real-time updates, and interfaces that stay legible when an agent is acting on the user's behalf.
  • Build high-performance visualizations of large, fast-moving datasets (spectrum, maps, time series).
  • Partner with product, design, and backend engineers to shape requirements and translate ambiguous goals into concrete interfaces.
  • Establish frontend engineering standards, accessibility, testing, code review, and CI practices and help the rest of the team adopt them.

Qualifications

  • 4+ years of professional frontend / UI engineering experience shipping production web applications.
  • Strong, hands-on experience with both Angular and React, and the judgment to know what each is good for.
  • Command of the modern UI stack: TypeScript, component-driven architecture, state management (e.g., Redux, Zustand, NgRx, signals), modern build tooling (Vite, esbuild, etc.), and testing (Jest, Vitest, Playwright, Cypress).
  • Demonstrated ability to design and build a UI architecture from scratch.
  • Experience integrating with real-time and streaming backends (WebSockets, SSE) and designing UI for asynchronous, long-running operations.
  • Interest in and experience with building interfaces for AI / agentic systems.
  • Strong product sense and attention to detail; you care how things feel, not just whether they work.
