Role Summary

This role is for a hands on Principal Front-End Engineer who writes production-quality code daily while shaping front-end architecture and engineering direction. It requires deep expertise in Angular, React, Node.js, TypeScript, and Progressive Web App (PWA) development. The engineer leads complex initiatives end to end, mentors teams through direct collaboration, and influences engineering decisions through practical implementation. Exposure to Java-based backend services is optional. Experience working in an onsite offshore delivery model is important for effective collaboration across distributed teams.

Core Responsibilities

• Build and deliver complex front-end features using Angular and React with a focus on clean, maintainable, and scalable code.
• Develop and optimize Progressive Web Apps, including service workers, offline-first strategies, caching layers, background sync, and installable experiences.
• Lead hands-on implementation of front-end architecture, design patterns, and shared component libraries.
• Collaborate with backend teams to integrate front-end applications with Node.js services and optionally Java-based backend APIs.
• Coordinate effectively within an onsite offshore model, ensuring smooth handoffs, clear communication, and alignment across time zones.
• Own performance tuning, Core Web Vitals improvements, bundle optimization, and rendering efficiency.
• Drive modernization efforts such as framework upgrades, migration strategies, and refactoring of legacy codebases.
• Conduct deep technical code reviews and pair-program with engineers to elevate code quality and engineering practices.
• Prototype new ideas, evaluate emerging technologies, and introduce tools that improve developer productivity.
• Work directly with UX and product teams to translate requirements into high-quality, user-centric interfaces.
• Contribute to CI/CD improvements, testing strategies, and deployment workflows for front-end and PWA applications.
• Mentor engineers through hands-on guidance, technical deep dives, and collaborative problem-solving.

Required Qualifications

• More than 10 years of total professional experience in front-end engineering, including significant time in senior or principal-level roles.
• Expert-level proficiency in TypeScript, including advanced typing, generics, decorators, and scalable application patterns.
• Deep, hands-on experience with Angular (v10+) and React (Hooks, Context, Redux or equivalent).
• Strong experience building and integrating Node.js services (Express, NestJS, or similar).
• Proven ability to build and ship Progressive Web Apps, including:
• Service workers
• App shell architecture
• Offline-first and caching strategies
• Web app manifest
• Push notifications and background sync
• Strong command of JavaScript/TypeScript, browser internals, rendering pipelines, and performance optimization.
• Demonstrated experience designing and implementing component libraries, design systems, or shared UI platforms.
• Hands-on experience with testing frameworks such as Jest, Cypress, Playwright, Jasmine/Karma.
• Solid understanding of RESTful APIs, authentication/authorization patterns, and front-end security.
• Experience working with cloud environments (AWS, Azure, or Google Cloud Platform) and modern CI/CD pipelines.
• Experience collaborating in an onsite offshore delivery model, including distributed team coordination and communication.
• Strong communication skills and the ability to influence engineering decisions through practical, hands-on leadership.

Preferred Qualifications

• Exposure to integrating front-end applications with Java-based backend services (Spring Boot or similar).
• Experience with SSR/SSG frameworks such as Next.js or Angular Universal.
• Experience with performance profiling tools and Core Web Vitals optimization.
• Contributions to open-source projects or internal frameworks.
• Experience in large-scale, distributed, or enterprise environments.

Must Have

• Angular, React, Node.js, TypeScript, and Progressive Web App (PWA)
