• Work with Git for version control and collaborate using GitHub or similar tools, including CI/CD pipelines.
• Troubleshoot and resolve complex technical issues across different environments.
• Use AI-driven development day to day, working with company-supplied AI agents such as Claude and Codex to speed up delivery while keeping quality high.
• Stay up to date with the latest web technologies and frameworks, and adopt new tools as they emerge.
• Work with DevOps teams to manage hosting, CDNs, and caching solutions for optimal website performance.
• Develop Integrations for web sites with 3rd-party platforms and tools.

TO DO IT, YOU WILL NEED:

• 4+ years of experience in frontend or full-stack web development.
• Solid experience building and shipping production websites or web applications, including custom themes, plugins, or components, and working with REST APIs.
• Proficiency in JavaScript, HTML5, CSS3, PHP, and MySQL
• Experience with performance tuning and optimization strategies for websites, including Core Web Vitals.

• Familiarity with infrastructure platforms like Cloudflare, AWS, and other hosting solutions.
• Strong problem-solving skills and ability to work independently.
• Experience with JavaScript frameworks and libraries such as React, Next.js, or NestJS would be considered an asset.
• Experience with WordPress (themes and plugins) is nice to have, but not required.
• Working knowledge of AI as a day-to-day workflow, using company-supplied AI agents such as Claude and Codex to plan, write, test, and review code, and for research, debugging, learning, and planning.
• Excellent communication and collaboration skills.
