Drive UI/UX excellence by closely collaborating with designers, product managers, and backend teams.
Own the quality of your code writing clean, maintainable, and well-tested components.
Establish and maintain comprehensive unit, integration, and end-to-end test coverage.
Influence and implement best practices for CI/CD, performance, and security in front-end engineering.
Actively contribute to architectural decisions, technical roadmaps, and system design discussions.
Mentor and support other engineers through code reviews, knowledge sharing, and hands-on collaboration.
Thrive in a dynamic environment with autonomy and ownership over key front-end domains.

A strong foundation in computer science, software engineering, or equivalent real-world experience.
Deep expertise in JavaScript, React, and TypeScript, with a proven track record of delivering production-grade SPAs at scale.
Experience architecting complex front-end systems, including modular component design, state management (e.g. Redux, Zustand, or equivalent), and performance optimization.
Solid experience with tooling and infrastructure: Webpack, Babel, npm/yarn, Git, Docker, etc.
A strong grasp of frontend testing strategies, including Jest, React Testing Library, and Cypress (or equivalents).
Familiarity with modern CI/CD pipelines and tools (e.g., GitHub Actions, CircleCI).
A security-first mindset and experience mitigating common frontend vulnerabilities.
Excellent communication and collaboration skills you're comfortable leading discussions, sharing knowledge, and driving decisions across teams.
A growth mindset, passion for continuous improvement, and willingness to mentor others.

Bonus points for:

Experience in designing frontend systems for SaaS or analytics-heavy platforms.
Familiarity with accessibility standards (WCAG) and internationalization.
Contributions to open-source projects or relevant tech communities.

Implement and maintain robust testing strategies, achieving comprehensive unit, integration, and end-to-end test coverage.
Drive improvements in CI/CD pipelines, performance optimization, and front-end application security.
Contribute to architectural decisions and establish best practices for front-end development.
Mentor and guide junior engineers, fostering a culture of learning and collaboration within the team.
Evaluate and adopt emerging trends and technologies to enhance the platform's technical capabilities and user experience.
