- Implement responsive, mobile-first layouts that work cleanly across devices and browsers.
- Integrate forms, email capture, basic analytics, and simple CMS or headless content sources.

- Evaluate AI-generated frontend output and refine markup, styling, structure, and copy placement to production quality.
- Troubleshoot layout, performance, and cross-browser issues independently.
Requirements and Benefits
- At least 3 years of relevant experience in frontend development, landing page production, or website development (required)
- Bachelor's or Master's Degree in Computer Science, Engineering, Information Technology, Design, or related fields is a plus

- Experience with utility-first CSS (Tailwind) or modern component libraries.
- Ability to translate Figma designs or written briefs into clean, maintainable code.
- Familiarity with form handling, email capture services, and basic analytics setup (GA4, Plausible, or similar).
- Working knowledge of on-page SEO, accessibility (WCAG basics), and Core Web Vitals.
- Comfortable working with simple CMSs or headless content (Webflow, Framer, Sanity, Contentful, or similar) is a plus.
- Strong attention to detail and visual taste — pages should look intentional, not generic.
- Self-directed work ethic with the ability to deliver complete pages with minimal supervision.
- Portfolio of shipped landing pages and/or small websites (required).
- English proficiency: Upper-intermediate (B2) or above (required).
