About the position
We're looking for a Senior UI/UX Frontend Developer who codes first but designs with empathy—someone who knows how to turn wireframes into production-ready websites using modern tools, clean architecture, and a deep appreciation for UX. Calcium+Company is a leading healthcare marketing agency driving smarter brand engagement through strategy, creativity, data, and technology. Within our Marketing & Innovation hub, the Technology & Experience Design team brings to life digital ideas that connect brands with audiences in meaningful ways—through thoughtfully coded, beautifully designed, and AI-enhanced experiences.

You'll also apply AI-powered tools and plugins to accelerate workflows—from code generation to design handoff. This is a coder-first role—but one that values elegance, efficiency, and experience as much as execution.
