About the role

  • **Overview**
  • We’re looking for a Senior Front-End React Developer to lead the direction of front-end
  • development for an enterprise B2B product. You’ll partner closely with a UI/UX designer working
  • in Figma and collaborate with product, backend, and QA teammates to ship responsive,
  • accessible, enterprise-grade applications, often featuring complex mapping experiences and
  • real-time alerting.
  • **What You’ll Do**
  • ● Lead front-end direction: establish patterns, architecture, and standards for React
  • development across the project.
  • ● Build high-quality, responsive user interfaces using React (and potentially MUI).
  • ● Translate Figma designs into polished, production-ready UI with strong attention to
  • interaction details.
  • ● Deliver map-heavy experiences (layers, markers, clustering, filtering, drawing tools,
  • performance tuning, etc.).
  • ● Implement real-time alerting UI patterns (streams, toasts, notification centers,
  • acknowledgment flows, severity states).
  • ● Ensure the product is accessible and meets WCAG best practices (keyboard navigation,
  • ARIA, contrast, screen reader support).
  • ● Collaborate in an agile environment: participate in planning, refinement, reviews, and
  • retros; break down work and estimate effectively.
  • ● Write maintainable code with strong testing practices and thoughtful documentation.
  • ● Improve performance, reliability, and developer experience through refactoring, tooling,
  • and CI/CD-friendly workflows.
  • ● Mentor teammates and contribute to a healthy, pragmatic engineering culture.

Requirements

  • **What You’ll Bring**
  • ● 5+ years building modern web applications, including deep experience with React.
  • ● Strong proficiency with TypeScript, HTML, CSS, and responsive design.
  • ● Experience implementing component systems and design libraries (ideally Material UI
  • (MUI) or similar).
  • ● Demonstrated ability to turn Figma designs into high-fidelity UI and reusable
  • components.
  • ● Proven ownership of front-end architecture (routing, state management, data fetching,
  • performance, error handling).● Experience building enterprise-grade applications with attention to security, scalability,
  • and maintainability.
  • ● Solid accessibility knowledge and track record of shipping accessible interfaces.
  • ● Familiarity with real-time data patterns (WebSockets, SSE, polling, event-driven UIs).
  • ● Comfort integrating mapping libraries and delivering performant map UIs (e.g., Mapbox
  • GL, Leaflet, Google Maps, OpenLayers).
  • ● Strong collaboration and communication skills—able to lead, influence, and align across
  • disciplines.
  • **Nice to Have**
  • ● Experience with data visualization (charts, dashboards, geospatial analytics).
  • ● Knowledge of testing frameworks (Jest, React Testing Library, Playwright/Cypress) and
  • component documentation (Storybook).
  • ● Experience with monorepos, micro-frontends, or design systems at scale.
  • ● Prior consulting experience: navigating ambiguity, balancing stakeholders, and delivering
  • iteratively.
