About MarvelX
MarvelX is building highly specialized AI agents for the most complex, heavily regulated industries. Think insurance claims, compliance, support. Automated by AI that actually works in the real world. The opportunity is massive, and we’re moving fast.

You’ll translate complex agent workflows into clear, reliable user experiences. You’ll prototype, ship, and iterate quickly, working closely with product, design, and engineering.
Your work will help define how businesses interact with AI in high-stakes environments where clarity, trust, and usability matter.
