Job Title: Senior UI/UX Designer Location: Remote — Open to candidates based in Canada or Latin America Department: Product & Design

Employment Type: Independent Contractor

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.

Our team of creators, builders, and investors specializes in marketing, technology, artificial intelligence, and business—so people with big ideas can expand their agency and live lives they find meaningful.

We partner with organizations of all sizes to explore, design, and implement AI strategies that are secure, scalable, and human-centered. From advisory and tooling to implementation and education, we meet clients where they are and help them integrate AI in ways that align with their mission and values.

At Human Agency, we believe AI should amplify human potential—not replace it. Our goal is to empower teams to work smarter, move faster, and unlock new possibilities through thoughtful, responsible innovation.

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 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.

Responsibilities Product & Experience Design

• 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.

Website Design & Delivery

• Lead end-to-end website experiences (marketing and product/Docs microsites): structure, UX, responsive UI, performance, and accessibility.
• Build or modify pages/components and production-ready prototypes using modern front-end practices (e.g., semantic HTML, CSS, basic JavaScript) or component libraries; collaborate with engineers on integration and release.

Brand & Visual Systems

• 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.

Research & UX Strategy

• 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.

Decision Architecture

• Model complex user journeys and decision trees (e.g., onboarding paths, eligibility flows, funnels, chat/automation logic) and translate them into simple, testable experiences.
• Maintain clear, versioned flow charts and logic maps for cross-functional alignment.

Cross-Functional Collaboration

• 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.
• Take ownership of systems; champion accessible, performant, and customer-obsessed design.

Experience

• A portfolio of shipped digital products and websites demonstrating end-to-end ownership—from research and concept through IA, interaction, visual design, coded prototypes, and release.
• Proven delivery of responsive websites and web apps with measurable outcomes (conversion lift, engagement, task success, retention) and clear rationale for decisions.
• Hands-on front-end implementation experience sufficient to build production-quality UI or coded prototypes (semantic HTML, CSS, basic JavaScript) and to collaborate effectively with engineers on component libraries/CMS.
• Demonstrated application of brand systems to product and web (typography, color, motion, and component scales) with attention to accessibility and performance.
• Primary UX research experience (interviews, surveys, usability tests) and translation of insights into prioritized roadmaps and design decisions.
• Experience modeling and optimizing multi-step flows and decision trees; use of diagrams/logic maps to align stakeholders and inform implementation.
• Design system stewardship (tokens, components, documentation) and partnership with engineering to maintain quality and consistency at scale.
• Comfort with analytics and experimentation (e.g., instrumentation planning, funnels, A/B tests) to validate decisions and drive continuous improvement.
• Experience operating in cross-functional, agile environments; mentoring designers; leading reviews and giving/receiving critique.

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.
• Practical front-end skills sufficient to implement prototypes and production-ready UI (semantic HTML, CSS, basic JavaScript) and to work effectively with engineers on component libraries.
• 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.
• Nice to have: startup experience; mentorship of other designers; familiarity with analytics, SEO basics, performance budgets, and accessibility standards.
