Responsibilities:

• Build and evolve scalable, high-performance web applications using React and Node.js 
• Collaborate with product managers, designers, and backend engineers to translate complex requirements into intuitive user experiences.
• Participate in code reviews, share best practices, and help maintain high engineering standards within the frontend team. Work closely with DevOps to streamline CI/CD pipelines, improve deployment reliability, and enhance observability through metrics and monitoring tools.
• Own features end-to-end — requirement refinement, implementation, testing, and delivery. Optimize frontend performance, focusing on loading times, rendering speed, and bundle efficiency.
• Ensure cross-browser and multi-device compatibility while meeting accessibility (a11y) and usability standards.
• Contribute to  modernization, refactoring, and performance enhancements to keep the platform scalable, maintainable, and aligned with product goals.
• Contribute and enforce engineering best practices across coding, documentation, testing, and review processes.
• Ensure strong automated test coverage and reliable CI/CD workflows that reduce manual effort and improve delivery predictability.
• Own operational excellence, including incident response, root-cause analysis, and long-term reliability improvements.
• Advocate for scalability, performance, security, and observability across the platform’s architecture and tooling.
• Identify technical risks, estimate complexity, and communicate trade-offs to leadership and stakeholders.

Qualifications & Skills:

• 4+ years of software development experience with strong expertise in modern frontend engineering at scale.
• Deep hands-on knowledge of React including component architecture, SSR patterns, RSC, and complex UI data flows. Proficiency with Node.js and MongoDB for server-side functionality.
• Strong understanding of modern styling systems and theming approaches (vanilla-extract, styled-components, design tokens).
• Solid TypeScript practices, including strict typing, shared contracts, and schema validation (Zod or equivalent).
• Experience with Module Federation.
• Good understanding of bundling and compilation, experience with webpack/rollup/vite/esbuild
• Experience with automated testing frameworks (Vitest/Jest) and end-to-end testing (Playwright/Cypress).
• Good understanding of backend integration patterns (REST, GraphQL, RPC-style APIs).
• Experience with CI/CD workflows (GitLab CI or similar), private registries, and secure artifact handling.
• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field.

Nice to Have:

• Experience building platforms or tooling used across multiple frontend teams (design systems, template engines, configuration frameworks).
• Experience with react-native/mobile experience.
• Knowledge of performance optimization strategies for client-side and server-side rendering.
• Understanding of accessibility, internationalization, and semantic UI design best practices.
• Experience developing SDKs, CLI tools, or developer-facing automation.
• Familiarity with event-driven UI flows, real-time interfaces, or edge-rendering strategies.
• Background improving developer platforms, observability stacks, or performance monitoring systems.
• Comfort with UI-as-data approaches and leveraging AI-assisted/no-code tooling to accelerate feature delivery.
