You will work with designs provided by our design team and turn them into responsive, polished, and reliable WordPress websites. The ideal candidate is a strong developer who also has a good eye for design, layout, typography, and color composition. You should be comfortable making minor visual and UX adjustments independently when needed, without requiring a designer for every small change. We are looking for someone who understands WordPress beyond page builders and pre-built themes and is comfortable working directly with PHP, HTML, CSS, JavaScript, custom themes, and custom plugins.

Who We're Looking For

You should be comfortable receiving a completed design and independently turning it into a polished, production-ready WordPress website. You should have enough visual judgment to recognize when something doesn't look right and make reasonable adjustments without requiring detailed direction for every spacing, sizing, color, or responsive-design decision. You should also be able to open an unfamiliar custom theme or plugin, understand how it works, troubleshoot problems, and make changes without rebuilding everything from scratch.
