• Design and implement advanced hydration strategies and rendering logic to maximize Google PageSpeed and Core Web Vitals performance. 

• Establish coding standards, frameworks, and best practices to ensure clean, reusable, and maintainable code across a multi-developer environment. 

• Define and document the component architecture, metadata schema, and lifecycle rules that govern how the CMS grows and scales. 

• Collaborate with the Director of Marketing Operations to translate high-level business and marketing goals into a scalable technical roadmap. 

• Work closely with the backend engineer to define data flows, optimize APIs, and ensure seamless integration between CMS components and backend data sources. 

• Mentor and direct the junior React developer, reviewing code, guiding implementation, and ensuring adherence to architectural standards. 

• Integrate and optimize advanced applications such as 3D visuals (Spline3D), analytics, and marketing tools without compromising site speed or stability. 

What You Bring 

• 7+ years of front-end engineering experience, including 5+ years deep in React architecture and performance optimization.  

• Proven success building and scaling React-based CMS or page-builder systems from the ground up. 

• Expertise in PageSpeed optimization, hydration strategy, and React rendering performance. 

• Strong grasp of component-driven architecture, code-splitting, and lazy hydration for high-performance environments. 

• Experience integrating design systems, managing Figma-to-React workflows, and maintaining organized component registries. 

• Ability to define and enforce clean, maintainable engineering standards in multi-developer environments. 

• Experience collaborating with backend teams on API design, data flow, and performance optimization. 

• Exposure or interest in advanced 3D or interactive experiences (e.g., Spline, React Three Fiber, or WebGL) with an understanding of how to integrate them efficiently without compromising performance. 

• Demonstrated leadership and mentoring skills, with clear communication across teams. 

Why You’ll Love It Here 

• Architect a global platform that supports millions of users and redefines how people interact with the law across continents.
