Lead Javascript Full-Stack Developer (ReactJS, Next.js)

You'll own the design of outstanding web experiences that look and feel like native mobile apps, defining performance optimization strategies for both desktop and mobile web view browsers (including iOS Safari). Partnering closely with backend leads, UX designers, product owners, and engineering management, you'll translate complex interactive designs into elegant, modular, and reusable front-end architectures — while building, coaching, and scaling a high-performing team of engineers and championing best practices across the department.
