Senior React Lead / Architect

About the Role:

We’re hiring a hands-on Tech Lead to architect and scale an internal investment insights platform for a top global private equity firm. The platform will be used across multiple internal product teams and requires reusable components, modular dashboards, and high-quality developer experience. This role blends technical leadership and consultative engineering. You’ll define frontend architecture, guide implementation, and work directly with Product, Design, and client Engineering leadership onsite in New York.

What You Will Do:

Platform & Component Architecture:

• Own the component library and frontend ecosystem used across multiple micro-apps
• Package, version, and distribute shared components with clear migration paths
• Support consumption in both Bootstrap and Tailwind environments without fragmentation
• Define testing strategy across units, integration, visual, and E2E levels

Technical Delivery:

• Lead the implementation of React-based micro-apps backed by AWS serverless (Lambda, API Gateway, Fargate)
• Define and enforce CI/CD standards for publishing and deployments
• Produce documentation, usage guides, and integration examples for downstream teams

Collaboration & Influence:

• Partner with Product and Design to translate ambiguous requirements into actionable plans
• Present architectural decisions to client Tech Leads and Engineering Committees
• Support a distributed engineering team (NY + offshore) through reviews, onboarding, and unblockers
• Communicate tradeoffs, assumptions, and alternatives clearly to mixed audiences

What We’re Looking For:

Experience:

• 12–15 years engineering experience with a strong frontend focus
• Deep experience with React and component-driven architecture at scale
• Experience with micro-frontend architectures (independently deployable modules)
• Experience building or extending component libraries (not just consuming)
• Familiarity with AWS serverless (Lambda, API Gateway, Fargate)
• Experience with CI/CD, containerization, versioning, and semantic versioning
• Comfortable working through evolving requirements and partial clarity

Frontend Technologies & Skills:

Rendering & Architecture:

• Client-Side Rendering (CSR)
• Server-Side Rendering (SSR) using frameworks such as Next.js

State Management

• Redux, Zustand, React Context, or state machines

Performance & Profiling

• Optimizing FCP/LCP, first paint, render time
• Tooling: Lighthouse, Core Web Vitals, Chrome DevTools, React Profiler

Real-Time Communication

• Experience with WebSockets for real-time experiences

Styling & Frameworks

• Bootstrap, Tailwind CSS
• CSS/SCSS, Styled Components, or CSS-in-JS approaches

Component Tooling

• Storybook for component development and documentation

UI Performance Testing

• Familiarity with metrics: TTI, TBT, FCP, LCP
• Tooling: Lighthouse, WebPageTest API, browser profiling, Web Vitals

Component Ecosystem Awareness (Nice to Have)

• Material UI, Ant Design, Chakra UI

How You Work:

We’re looking for someone who:

• Communicates tradeoffs and proposes pragmatic, supportable solutions
• Works autonomously and drives decisions forward even with partial clarity
• Explains architectural reasoning clearly to both technical and non-technical stakeholders
• Collaborates closely with Product and Design to shape solutions, not just execute tickets
• Treats documentation, onboarding, and developer experience as essential parts of delivery

Why This Role:

• Strategic, multi-year platform initiative with high visibility
• Direct onsite collaboration with senior Product, Business, and Engineering leaders
• Real architectural ownership beyond feature delivery
• Opportunity to shape developer experience and platform standards across teams
