GN - Frontend Engineer (React+typescript) - 214

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.

Tech Stack (Typical)

● React + TypeScript

• MUI (Material UI) (or comparable component library)
• Modern state/data tooling (e.g., React Query, Redux Toolkit, Zustand—depending on

project needs)

● Real-time transport (WebSockets/SSE)

• Mapping libraries (Mapbox GL / Leaflet / Google Maps
