Why this role exists:
This role exists to architect and deliver scalable, high-performance web interfaces. You’ll help us drive user engagement and shape our core product direction by owning the frontend architecture, mentoring the engineering team, and championing UI/UX best practices from initial design all the way to deployment.
What you’ll drive:
Architecture & Strategy
- Architect scalable and maintainable front-end solutions using React, modern JavaScript, and TypeScript.
- Drive the adoption of efficient state management and modular build processes (e.g., Webpack, module federation).
- Design resilient, failure-tolerant systems that account for load, performance, and web security (CORS, CSP, OWASP).
Delivery & Execution
- Ship complex, high-quality code to production in a timely manner to meet crucial business expectations.
- Optimize web pages for maximum speed and scalability by deeply tuning the event loop and rendering steps (style, layout, paint, composite).
- Validate code reliability by building out comprehensive testing infrastructure (Jest, React Testing Library, unit/integration testing).
Team & Leadership
- Mentor junior developers and elevate team standards through thorough, constructive code reviews.
- Partner with Product Managers, Designers, and Delivery Managers to align technical execution with overarching business goals.
- Unblock the team by debugging deeply rooted technical issues and creating Proof of Concepts (POCs) for new technologies.
