Vendor & Partner Steering: Lead and direct external frontend development teams (L2/L3/Dev). Provide unambiguous requirements, conduct regular sprint planning and review sessions, and ensure the timely delivery of high-quality, tested, and maintainable code.
User Experience & Performance: Champion a user-centric and performance-first culture. Utilize analytics, user feedback, and A/B testing to make data-driven decisions. Define and monitor Core Web Vitals and other performance metrics to ensure an exceptional user experience across all devices and regions.
Technology & Innovation: Stay at the forefront of frontend and headless technologies (JAMstack, SSG, SSR, Edge Computing). Proactively identify and advocate for new tools and methodologies that can drive innovation, improve developer experience, and enhance our digital presence.

Be cautious of an offer made with no real interview, or pressure to decide quickly or share financial details early.
