## Description

We are looking for a hands-on Senior Frontend Engineer (all genders) to own both of our websites. SCAYLE.com is the home of SCAYLE Commerce Engine, our enterprise platform for leading fashion and lifestyle brands. SCAYLESTUDIOS.ai is the home of SCAYLE STUDIOS, our AI photo studio with self-service sign-up and checkout. Until now, an agency ran our websites. We are bringing everything in-house to move faster, build more ourselves, and turn our most important channel into a real growth engine.

 * Execute scayle.com Replatforming: Transition from WordPress to a modern, AI-enhanced stack to accelerate deployment, eliminate agency reliance, and maintain an engaging, high-performing, premium UX.
 * Spearhead SCAYLE STUDIOS Web Experience: Assume ownership of scaylestudios.ai to build high-converting navigation, landing pages, onboarding flows, and activation-focused modules.
 * Advance SEO, GEO & Site Speed: Manage technical SEO and Generative Engine Optimization (GEO) to maximize search and LLM indexing while maintaining optimal speed across media-rich sites.
 * Enhance Analytics & Conversion Rates: Collaborate with the Demand team to implement event tracking, A/B testing, and conversion metrics to systematically optimize user journeys.
 * Foster Cross-Functional Alignment: Work directly alongside Content, Product, and Demand units to quickly transform growth initiatives into live, high-performing web experiences.
 * Adopt AI & Empower Non-Technical Teams: Embed AI coding tools (such as Claude Code) into engineering workflows and build secure, streamlined publishing pathways for non-technical stakeholders.
