We are seeking a highly experienced and technically proficient Senior Frontend Engineer to join our team. The ideal candidate has a deep understanding of the JavaScript ecosystem, with expert-level proficiency in React and TypeScript, and substantial experience working with both modern functional components/hooks and maintaining class-based JavaScript/React components. You will be a key contributor to the architecture, design, and implementation of highly scalable, performant, and user-friendly web applications.
Key Responsibilities
- Architect, develop, and maintain complex, high-quality user-facing features using React, TypeScript, and modern JavaScript (ES6+).
- Demonstrate strong expertise in Object-Oriented Programming (OOP) principles and patterns in JavaScript/TypeScript, actively using classes and inheritance to structure complex application logic (e.g., state machines, complex data models, or core business logic like in a video editor).
- Ensure the technical feasibility and optimal implementation of UI/UX designs, working closely with designers and product managers.
- Write clean, well-tested, and reusable code, adhering to best practices and coding standards (unit, integration, and end-to-end testing).
- Optimize application performance, scalability, and maintainability across various devices and browsers.
- Contribute to frontend architecture decisions, technology evaluations, and setting engineering best practices.
Required Qualifications and Experience
- 5+ years of professional experience in frontend web development.
- Expert proficiency in JavaScript (ES6+) and the JavaScript object model.
- Experience with React.js, including a strong understanding of core principles, component lifecycle, and state management.
- Expertise in TypeScript and its application in large-scale React applications to ensure code quality and maintainability.
- Proven experience working with and maintaining existing class-based JavaScript and React components (a specific requirement for this role).
- Experience with consuming and integrating with RESTful APIs.
- Strong understanding of web performance optimization techniques and cross-browser compatibility issues.
- Excellent problem-solving, analytical, and communication skills.
Bonus Points
- Experience with server-side rendering frameworks like Next.js or Remix.
- Familiarity with modern testing frameworks (Jest, React Testing Library, Cypress).
- Knowledge of cloud platforms (AWS, Azure, or GCP) and CI/CD pipelines.
- Experience with UI accessibility standards (WCAG).
- A Bachelors degree in Computer Science, Engineering, or a related field.
