Software Development Engineer (SDE) – Frontend

# Software Development Engineer (SDE) – Frontend **On-Site, Hyderabad, India · Full-Time** > **Only apply if:** You have **≥ 1 year** of production-grade frontend experience with strong, demonstrable expertise building and shipping scalable **React / Next.js** applications — **and** you can point us to **live, deployed products** you have built. --- ## Who We Are We are a fast-growing product startup building intelligent, AI-powered software for modern businesses. Our focus is on crafting seamless, high-performance user experiences powered by scalable backend systems and data-driven intelligence — and we ship to real customers every week. As we scale, we are looking for a **Frontend-focused SDE** who thrives in a fast-paced environment and can take end-to-end ownership of frontend architecture and user experience across a complex, multi-surface product. --- ## What You'll Do ### Core Frontend Development - Build production-grade applications using **Next.js (App Router), React 19, TypeScript, and Tailwind CSS**. - Architect scalable, reusable component libraries and design systems on top of **shadcn/ui / Radix primitives**. - Implement modern UI patterns using hooks, context, and advanced state management. - Optimize performance using code-splitting, lazy loading, caching, and **SSR / SSG / ISR / CSR** strategies. - Ensure pixel-perfect, responsive, accessible UI across devices and browsers. ### UI/UX Engineering Excellence - Translate product requirements and Figma designs into robust frontend implementations. - Build complex **dashboards, data visualizations, and interactive multi-step workflows** (charts, tables, maps, geographic intelligence, analytics views). - Build **AI-driven, streaming interfaces** — chat/agent UIs, token-by-token streaming, real-time updates, and rich message rendering (markdown, code, math). - Integrate real-time features using **WebSockets, SSE / streaming APIs, or event-driven updates**. - Ship accessible, SEO-friendly, high-performance web interfaces measured against Lighthouse best practices. ### Frontend Architecture & Scalability - Design scalable folder structures and modular, maintainable frontend architecture. - Implement server- and client-state management using **TanStack Query** and **Zustand** (or equivalent modern solutions). - Build robust forms with **React Hook Form + Zod** validation. - Integrate with backend services (TypeScript/Node and Python) over **REST and/or GraphQL** APIs. - Ensure robust error handling, observability, and performance monitoring. - Drive frontend testing strategy with **Vitest / Jest, React Testing Library, and Cypress/Playwright**. - Contribute to **embeddable / SDK-style frontend artifacts** (e.g. CDN-delivered, shadow-DOM-isolated widgets) where relevant. ### Engineering & Collaboration - Conduct structured code reviews and enforce high-quality coding standards. - Collaborate closely with backend engineers, product managers, and designers. - Contribute to CI/CD workflows and deployment pipelines. - Take ownership of features from concept to production release. - Mentor junior engineers and uphold engineering best practices. --- ## Must-Have Qualifications ### Core Frontend Expertise - **≥ 1 year** of production experience building scalable web applications. - Strong command over **Next.js, React, TypeScript, and modern JavaScript (ES6+)**. - Deep understanding of rendering strategies (**SSR, SSG, ISR, CSR**) and when to use each. - Advanced **Tailwind CSS** knowledge and experience building custom design systems. - Experience with frontend performance optimization and profiling. ### API & Integration - Experience integrating frontend applications with **Node.js and Python** backends. - Strong understanding of **REST APIs and/or GraphQL**. - Familiarity with authentication systems (**JWT, OAuth, session-based auth**). - Experience handling large datasets, paginated/infinite APIs, and streaming responses. ### Frontend Ecosystem Knowledge - Server/client state management (**TanStack Query / React Query, Zustand, Redux Toolkit**). - Form management (**React Hook Form, Zod/Yup validation**). - Data fetching and caching strategies. - Component-driven development; experience with design systems / Storybook is a plus. - **Data visualization** libraries (Recharts, D3, ECharts, Nivo, or similar). ### DevOps & Quality - Experience with **Docker-based local development** workflows. - CI/CD familiarity (GitHub Actions, GitLab CI, etc.). - Strong Git workflows and collaborative branching strategies. - Testing mindset spanning unit, integration, and E2E coverage. ### Engineering Mindset - Clean, maintainable code adhering to SOLID principles. - Strong debugging and performance-profiling skills. - Ownership-driven, product-first thinking. - Comfortable working independently in an **in-office startup environment**. --- ## Critical Requirements – High Weightage > **This is non-negotiable. Applications without these will not be prioritized.** ### Portfolio, Live Products & Demos You must be able to **show, not just tell**. With your application, explicitly share: - **An active GitHub profile** showcasing real, production-grade frontend code (not just tutorials or forks). - **Live, deployed projects** — public URLs we can open and interact with right now. Next.js + TypeScript projects strongly preferred. - **Live demos / a portfolio site** where you specifically showcase your **UI/UX work** — the visual quality, interaction design, responsiveness, and polish you are personally responsible for. - Demonstrated ability to build **complex dashboards, SaaS products, AI-integrated UIs, or data-heavy interfaces**. - Clean code structure, thoughtful architecture, and clear documentation. **In your application, please include direct links to:** https://forms.gle/FPUtQZ9ebgHPeAH59 1. Your GitHub profile (and 1–3 specific repos you're proud of). 2. At least one **live deployed product** (URL) you built or substantially contributed to. 3. A **portfolio / demo** that highlights your UI/UX craftsmanship. Tell us, for each link, exactly what you built and which parts are yours. ### Technical Assessment We will evaluate your: - Frontend architecture design and scalability decisions. - Code quality and maintainability. - Performance optimization strategy. - Ability to convert product requirements into production-ready UI. - End-to-end ownership during feature implementation. --- ## Nice-to-Have - Experience building **AI-powered, streaming, or data-heavy interfaces**. - Knowledge of **WebSockets, streaming UIs, and real-time collaboration** features. - Experience building **embeddable widgets / SDKs** (shadow-DOM isolation, CDN delivery). - Experience with design systems and internal UI libraries. - Exposure to animation libraries (**Framer Motion, GSAP**). - Contributions to open-source React/Next.js projects. - Experience working in early-stage startups. --- ## What We Offer - Competitive salary with a strong growth trajectory. - High-impact role with direct influence on product direction. - Opportunity to work on cutting-edge AI-driven products. - Fast execution cycles and a strong ownership culture. - Learning budget for courses and certifications. - Collaborative in-office engineering culture in **Hyderabad**. --- **https://forms.gle/FPUtQZ9ebgHPeAH59** If you are passionate about building scalable, beautiful, and high-performance frontend systems — and want to shape the product experience of a growing startup — **send us your GitHub, your live products, and your portfolio.** We'd love to see what you've shipped.
