Job Purpose

As a Frontend Engineer, you will play a key role in designing, building, and maintaining high-performance, scalable, and resilient software systems with a strong focus on frontend development. You will collaborate closely with cross-functional teams to architect technical solutions, define implementation strategies, and ensure superior user experiences across large-scale applications.

While your primary focus will be on browser-side development, you will also work on backend-for-frontend (BFF) logic when needed — contributing to a cohesive, reliable, and efficient end-to-end architecture. This role requires a strong sense of technical ownership, autonomy, and active participation in design discussions, code reviews, and continuous improvement initiatives.

Responsibilities

Technical Leadership & Architecture

• Architect, design, and implement complex frontend solutions ensuring scalability, security, and reliability.

• Collaborate with product and engineering teams to define technical strategies and implementation plans.

• Contribute to shared ownership of the project’s mission, fostering accountability and alignment across the team.

Development & Code Quality

• Write clean, efficient, and maintainable code for both frontend interfaces and backend-for-frontend layers.

• Conduct code reviews, provide constructive feedback, and promote best engineering practices.

• Ensure adherence to accessibility, responsive design principles, and performance standards.

Problem Solving & Troubleshooting

• Identify and resolve performance bottlenecks, optimizing rendering paths, caching, and bundling strategies.

• Debug complex issues across multiple layers of the stack.

• Support continuous improvement by monitoring system behavior and implementing enhancements.

Experience & Qualifications

• 5+ years of experience building and maintaining large-scale frontend applications.

• Strong proficiency in JavaScript (ES6+), HTML5, and CSS3, with experience managing styles across complex applications.

• Hands-on experience with modern component-based frameworks or metaframeworks, especially NextJS and ReactJS.

• Solid experience optimizing frontend performance (critical rendering path, caching, module bundling).

• Strong knowledge of testing methodologies with experience in unit, integration, and acceptance tests.

• Familiarity with Git, collaborative workflows, and working with RESTful APIs.

• Advanced English skills (written and spoken), capable of collaborating in distributed teams.

Nice to Have

• Experience with TypeScript and component architectures at scale.

• Broader understanding of backend-for-frontend (BFF) patterns.
