Staff Software Engineer

This role is for one of the Weekday's clients

Salary range: Rs 5000000 - Rs 8000000 (ie INR 50-80 LPA)

Experience: 8+ yrs

Location: Bengaluru

Job Type: full-time

We are seeking a Staff Frontend Engineer to be the technical anchor for our frontend capability. This role goes beyond feature delivery — you will define the frontend architecture, establish the component design system, own the Next.js application structure, drive performance standards, and mentor Senior and mid-level frontend engineers. You will build the most complex, data-intensive UI surfaces: real-time attribution dashboards, AIpowered campaign builders,and platform-embedded intelligence widgets — all in a React + Next.js stack integrated with Elasticsearch-powered search and streaming AI responses

Key Responsibilities

• Own and evolve the frontend architecture: Next.js App Router structure, component boundaries, state management strategy (Redux), and data-fetching patterns — applying hexagonal UI principles where the component layer is decoupled from specific backend service contracts.
• Design and build the most technically complex UI surfaces: real-time attribution dashboards (streaming data), AI-powered campaign builder (LLM response streaming), Elasticsearch-backed customer search with faceted filtering, and platform-embedded opportunity cards.
• Define the component design system: atomic component library, theming contracts, accessibility standards (WCAG 2.1), and Storybook-based documentation.
• Establish frontend performance standards: Core Web Vitals targets, bundle size budgets, SSR/SSG strategy with Next.js, lazy loading, and virtualization for large data tables.
• Lead Next.js architecture decisions: App Router vs. Pages Router tradeoffs, RSC (React Server Components) applicability, streaming SSR for AI-generated content, and API route design.
• Integrate AI-native frontend patterns: streaming LLM responses into UI components, real-time score updates from Redis/Aerospike via SSE, and Elasticsearch typeahead search.
• Drive code quality through design reviews, code reviews, pair programming, and frontend-specific engineering standards.
• Mentor Senior and mid-level frontend engineers — setting the bar for component design, test coverage, and performance discipline.
• Collaborate closely with backend Staff Engineers to define API contracts and with designers to implement pixel-perfect, accessible UIs

Skills & Qualifications

• 8+ years of frontend engineering experience with deep React and Next.js expertise in production systems.
• Mastery of Next.js 14+ App Router, React Server Components, streaming SSR, and static generation —knowing when to apply each pattern.
• Strong TypeScript expertise: type safety across component props, API contracts, Redux store shape, and server/client boundaries.
• Deep Redux expertise: slice design, selector optimization, middleware patterns, and RTK Query for data fetching.
• Proven experience building data-intensive dashboards with real-time data (WebSocket, SSE, or polling) and chart libraries (Recharts, D3.js).
• Experience integrating Elasticsearch-powered search UIs: typeahead, faceted search, and result ranking display.
• Strong frontend performance engineering: bundle analysis, code splitting, memoization, virtualization, and Core Web Vitals optimization.
• Experience establishing and maintaining component design systems with accessibility standards.
• Experience mentoring engineers and raising the technical bar across a frontend team.

Good to Have

• Experience streaming LLM/AI-generated content into React UI components (token streaming, partial rendering patterns).
• Familiarity with platform-embedded micro-frontend patterns (module federation or iframe-based embedding).
• Background in automotive retail, eCommerce analytics, or SaaS BI/reporting platforms.
• Experience with Storybook for component documentation and visual regression testing.

Perks & Benefits

• Competitive compensation and generous stock options.
• Medical insurance coverage.
• Work with some of the brightest minds from Silicon Valley's most dominant and successful
