Product Designer, Design Systems - Mississauga

Photon is seeking an experienced product designer to design and build UI components and tools that enhance user experiences, particularly in AI-assisted workflows. The role involves collaborating with designers and engineers to create user-friendly systems and maintain design libraries.

Responsibilities:

• Design reusable components and patterns that align with design principles and support consistent implementation across products
• Create, maintain, and evolve shared UI libraries, templates, and tokens in Figma
• Define and refine system-level patterns for AI‑assisted workflows, agentic experiences, and generative or dynamic UI
• Create UX patterns for multi‑step task orchestration, human‑in‑the‑loop review, and other AI‑supported workflows
• Translate emerging product needs into scalable design system solutions, and document patterns and guidance that enable teams to adopt and extend the system effectively
• Partner with designers, engineers, and product managers to ensure system patterns are feasible, implemented consistently, and meet product needs; review usage to identify gaps and improvement opportunities
• Advocate for accessibility across all design system work, including new AI‑driven experiences
• Establish design system guardrails that reduce ad‑hoc AI UX decisions and improve consistency, quality, and speed across teams
• Contribute to the ongoing evolution of the design system as new AI interaction models and more adaptive product experiences emerge

Requirements:

• 4+ years of product design experience in a product-focused technology organization
• 2+ years of experience designing and evolving design systems, including reusable components, patterns, and documentation
• Portfolio should demonstrate both design systems work and product design for AI-enabled or workflow-heavy experiences
• Strong skills in visual design, interaction design, and prototyping, demonstrated through a portfolio of desktop and mobile work
• Strong command of Figma, including component libraries, variables, and advanced system workflows
• Prior experience designing and shipping AI-enabled product experiences, including AI-assisted workflows, agentic interactions, or generative UI
• Ability to work within an established direction while independently defining new patterns when needed
• Experience working closely with cross-functional partners, especially engineering and product
• Strong organizational and communication skills, with the ability to simplify complex concepts and document decisions clearly
• Bachelor's/University degree
• Formal UX education or equivalent professional experience
• Experience defining design system guidance for AI-enabled product experiences
• Experience creating patterns for adaptive, dynamic, or context-aware interfaces
• Experience with design tokens, variables, and implementation-minded system thinking
• Strong understanding of accessibility standards such as WCAG and how they apply to evolving interaction models
• Ability to connect product needs to reusable system solutions that improve consistency and reduce rework
• Experience helping teams adopt design systems through documentation, reviews, and practical guidance
• Comfort working in ambiguity and shaping standards in an area that is still evolving
