• Lead code reviews and promote consistent application of coding best practices.

• Establish and advocate standards for component design, state management, and frontend architecture.

Learning & Technical Growth

• Develop expertise in frontend architecture, performance optimization, and large-scale application design.

• Evaluate and adopt new technologies and tools where appropriate.

• Contribute to technical discussions and internal knowledge-sharing initiatives.

Collaboration

• Work closely with Product, Design, and Backend teams to define frontend solutions, API contracts, and integration approaches.

• Break down complex technical problems into manageable tasks and guide execution within the team.

• Provide technical mentorship to junior engineers and support their professional development.

• Communicate technical decisions, trade-offs, and risks effectively to stakeholders.

Production Ownership

• Lead the debugging and resolution of complex production issues.

• Drive improvements in monitoring, logging, and frontend performance tracking.

• Ensure the reliability, scalability, and performance of frontend applications.

Qualifications & Experience

• 5 to 7 years of software engineering experience with a strong focus on frontend development.

• Expert proficiency in JavaScript, HTML, and CSS.

• Strong hands-on experience with React and TypeScript in production environments.

• Solid understanding of frontend architecture, state management, and component-driven development.

• Experience designing and building scalable, high-performance web applications.

• Strong understanding of browser internals, rendering behavior, and performance optimization.

• Experience with frontend testing strategies and frameworks such as Vitest, Jest, and React Testing Library.

• Proficiency with modern frontend tooling and build systems.
