Senior UI/UX Designer - Remote

Location: Remote — Open to candidates based in Canada or Latin America
Department: Product & Design
Employment Type: Independent Contractor

We’re scaling rapidly and have a growing pipeline of opportunities that demand exceptional talent across disciplines. Our mission is to bring on individuals, from creative producers to technical experts to entrepreneurial leaders, who can help us realize this next chapter of growth.

We are a company of doers. Leaders roll up their sleeves, teams work flat, and everyone contributes to what ships. Titles don’t insulate us from feedback or basics. We invite critique, learn quickly, and keep raising the bar. The best ideas win here, no matter where they come from, because clients trust us to deliver the strongest outcomes every time.

Our clients’ missions, products, and bottom lines are sacred. We immerse ourselves in their world, becoming stewards of their goals and partners in solving big problems. Every product, strategy, or asset we create must be both beautiful and functional; practical, usable, and designed for real-world impact.

Humans are our most valuable resource, and we only grow by hiring people who push us forward. Across strategy, engineering, design, data, and operations, we seek out teammates who raise the bar and make us better. Always hire up, never down.

We partner with organizations of all sizes to explore, design, and implement AI strategies that are secure, scalable, and human-centered. We believe AI should amplify human potential, not replace it and we build with that conviction in every engagement. From advisory and tooling to implementation and education, we meet clients where they are at and help them integrate AI in ways that align with their mission and values. Our goal is to empower teams to work smarter, move faster, and unlock new possibilities through thoughtful, responsible innovation.

And through it all, we lead with purpose, love, and adventure. We do meaningful work with people we care about, and we make the ride an adventure worth taking. Because at Human Agency, who we are and how we work are one and the same.

The Senior UI/UX Designer will lead end-to-end product and web experience design across research, strategy, interaction, and visual execution. You’ll collaborate with product, engineering, and marketing to solve complex problems, elevate usability, ship production-ready interfaces, and steward our brand and design system. This role suits a craft-obsessed designer who moves from insight to elegant, shippable UI—and communicates clearly with technical and non-technical partners.

This is an international independent contractor role, open to candidates based in Canada or Latin America to better align with U.S. time zones and operational needs. You will be engaged as an independent contractor and not as an employee of Human Agency. You are responsible for managing your own taxes, benefits, and compliance with local regulations. This engagement does not create an employer–employee relationship under applicable law.
