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

You'll head the design of outstanding web experiences that look and feel like native mobile apps, owning performance optimization strategies for both desktop and mobile web view browsers (including iOS Safari). Partnering closely with backend engineering leads, UX designers, and product leadership, you'll translate complex interactive designs into elegant, modular, and reusable front-end architectures — while managing, mentoring, and growing a team of engineers and championing best practices across the organization.

- Establish organization-wide strategies for managing complex client-side state (e.g., Redux, Zustand, Context API) and drive robust integrations with backend RESTful or GraphQL APIs
- Set the bar for engineering quality: define coding standards, drive code review culture, and lead the evolution and governance of our shared UI component library and design system
- Lead, mentor, and grow a team of senior, mid-level, and junior developers, conducting performance reviews, fostering career development, and cultivating a culture of technical excellence
- Partner with product, design, and engineering leadership to shape the long-term technical roadmap, drive architectural decisions, and align front-end strategy with business objectives
