About Us

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.

Role Overview

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-quality 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 to better align with U.S. time zones and operational needs.

Responsibilities

• Own information architecture, interaction design, and UI for core tools and new features to deliver exceptional user experiences.
• Design detailed user flows, wireframes, and high-fidelity interfaces for testing and developer handoff.
• Create, test, and refine prototypes of varying fidelity; partner with engineering to visually QA UI through implementation.
• Lead end-to-end website experiences (marketing and product/Docs microsites): structure, UX, responsive UI, performance, and accessibility.
• Translate brand strategy into systematized UI: typography, color, grids, motion, and component patterns.
• Maintain and evolve our design system and documentation to ensure consistency across products and web.
• Plan and conduct interviews, surveys, and usability tests; synthesize insights into clear problem statements, opportunity areas, and prioritized roadmaps.
• Define success metrics and incorporate findings into iterative design cycles.
• Model complex user journeys and decision trees and translate them into simple, testable experiences.
• Work with product, engineering, and client-facing teams to define objectives, user journeys, and visual specs; communicate design vision and product strategy across the organization.

Qualifications

• 5+ years designing web and/or mobile products with a portfolio spanning research, prototyping, and polished UI.
• Demonstrated ability to design and deliver websites (architecture, responsive layouts, accessibility), not just product UI.
• Depth in at least one: interaction design, information architecture, motion, or visual design; strong grasp of user-centered design principles.
• Experience planning and executing UX research (interviews, surveys, usability testing) and translating insights into product decisions.
• Proven ability to map and optimize complex decision trees and multi-step flows.
• Proficiency with modern design/prototyping tools (e.g., Figma) and collaborative product workflows; excellent documentation and communication in English.
