Sr Associate Engineer

Responsibilities

• Architect and ship React + TypeScript features with strong component design, custom hooks, and performance tuning (render paths, memoization, code splitting, lazy loading).
• Drive design-system-first development using ADS and Material UI; extend shared components without fragmenting the UX.
• Own state and routing patterns: Redux at scale, pragmatic adoption of Zustand, and React Router v5 navigation and deep-linking concerns.
• Design and implement complex product UI: high-density grids, dashboards, widgets, drag-and-drop, and charts with resilient loading, error, and empty states.
• Define integration contracts for REST and GraphQL; partner on BFF (Backend-for-Frontend) design, pagination, caching, and client-side mapping layers.
• Advance monorepo practices (pnpm, Nx): shared libraries, versioning, build graph optimization, and cross-package API stability.
• Establish the testing strategy: Vitest + RTL (React Testing Library) for fast feedback; Cucumber + Playwright BDD E2E for critical journeys.
• Champion i18n (internationalization) and a11y (accessibility) using WCAG-oriented patterns, keyboard flows, screen reader behavior, and RTL/locale edge cases.
• Guide microfrontend and module federation boundaries (shared dependencies, runtime composition, isolation, and failure modes).
• Own Vite/Webpack build configuration tradeoffs, bundle analysis, and platform tooling (Docker/Tilt, feature flags, internal API clients).
• Lead production support: debug with Grafana, Splunk, and distributed traces/logs; write actionable incident notes and preventative fixes.
• Own release to production: release trains, rollback judgment, coordination with SRE/platform, and Harness/Argo CD pipelines.
• Resolve Snyk, SAST, and dependency vulnerabilities; embed secure SDLC practices in team workflows.
• Mentor junior and mid-level engineers via reviews, pairing sessions, and technical RFCs; represent the frontend team in cross-team design reviews.
• Optionally lead or spike React Native initiatives (native tooling, debugging, shared logic extraction).
• Required Qualifications
• Core Web (Expert-Level Application)
• Deep HTML/CSS skills applied through design systems rather than ad-hoc styling.
• Advanced TypeScript (generics, discriminated unions, utility types, strict typing for API models).
• Web Components literacy (custom elements, shadow DOM, and interoperability with React hosts where applicable).
• React Platform Leadership
• 5+ years of experience building large, long-lived frontend products; 3+ years of experience leading features in React.
• Proven performance optimization in data-heavy UIs (virtualization, debouncing, selector patterns, profiling).
• Strong component API design: composability, accessibility props, testability, and extension points.
• Architecture & Tooling
• Production experience with monorepos (pnpm, Nx), shared packages, and internal design libraries.
• Vite and/or Webpack expertise; familiarity with module federation and microfrontend operational concerns.
• GraphQL client patterns (caching, error policies, colocated queries) plus robust REST client abstractions.
• BFF collaboration: shaping payloads for UI needs, auth/session handling at the edge of frontend concerns.
• Quality, Security & Operations
• Testing leadership: RTL + Vitest, meaningful coverage of behavior (not implementation detail); E2E strategy with Playwright/Cucumber.
• Hands-on vulnerability remediation (Snyk, npm audits, SAST triage) and secure dependency management.
• Produc
