📍 Job Overview

Job Title: Senior Product Designer UI/UX Company: MASV Location: Canada (Remote) Job Type: Full-Time Category: Product Design / UX/UI Date Posted: January 16, 2026 Experience Level: 5-10 Years Remote Status: Fully Remote

🚀 Role Summary

• Drive the end-to-end user experience (UX) and user interface (UI) design for complex web applications, focusing on B2B SaaS products.
• Establish and maintain a scalable Design System to ensure consistency and efficiency in product development and engineering execution.
• Collaborate closely with Go-To-Market and Engineering leaders to translate business problems into user-centered design solutions and product requirements.
• Act as the primary owner of the design culture, championing best practices and proactive problem-solving within a lean, fast-moving product team.
• Utilize data-driven methodologies and rapid prototyping to validate design concepts and ensure alignment with customer needs and business objectives.

📝 Enhancement Note: This role is positioned as the "First Founding Designer," implying significant ownership and the opportunity to shape the design function from its foundational stages. The emphasis on "owning" and "defining" the design culture suggests a strategic, high-impact position beyond typical individual contributor roles. The specific mention of working directly with "Go-To-Market leaders (who define the 'Why')" and "Engineering leaders (who define the 'How')" highlights a deep integration into the core product strategy and development lifecycle, characteristic of senior or lead design roles in growth-stage companies.

📈 Primary Responsibilities

• Visualize complex business problems and translate them into wireframes, user flows, and rapid prototypes during the product definition phase to validate requirements before development.
• Build, maintain, and evolve a lightweight, scalable Design System that aligns with the frontend architecture, enabling engineers to efficiently implement high-quality UIs.
• Design for progressive delivery by defining MVP (Minimum Viable Product) and future state visions, ensuring value is delivered iteratively and quickly.
• Act as a key liaison between customer needs, business requirements, and engineering constraints, proactively identifying and mitigating usability risks early in the design and documentation process.
• Champion a "documentation mindset," ensuring all design decisions, specifications, and rationale are clearly documented and communicated to facilitate collaboration and reduce cognitive load for engineering teams.
• Partner with product and engineering teams to conduct user research, usability testing, and analyze data to inform design decisions and validate product hypotheses.
• Contribute to defining and refining product strategy by providing insights into user behavior, market trends, and design best practices.
• Foster a collaborative design culture by actively participating in design reviews, providing constructive feedback, and mentoring other team members as the design function grows.

📝 Enhancement Note: The responsibilities emphasize a proactive and strategic approach to design, moving beyond screen design to encompass design operations, system building, and cross-functional leadership. The focus on "progressive delivery" and "phasing" indicates an Agile development environment where iterative design and development are critical. The extensive use of terms like "establish," "champion," "bridge the gap," and "translate complexity" points to a senior-level role responsible for defining processes and standards.

🎓 Skills & Qualifications

Education: While no specific degree is mandated, a strong portfolio demonstrating equivalent practical experience and expertise in UX/UI design principles is expected. A degree in Design, Human-Computer Interaction, or a related field is beneficial but not strictly required. Experience: 4+ years of professional experience in designing complex web applications, with a strong preference for experience in B2B SaaS environments.

Required Skills:

• Expert proficiency in modern design and prototyping tools, specifically Figma (including Auto-layout, Components, and Variables).
• Proven ability to translate abstract business problems into clear, user-centered design solutions through wireframes, user flows, and interactive prototypes.
• Strong understanding of fundamental web technologies (HTML, CSS, JavaScript) to design feasible and technically sound solutions, enabling effective communication with engineering teams.
• Experience in establishing and maintaining Design Systems, including component libraries and style guides, to ensure UI consistency and development efficiency.
• Demonstrated ability to design for progressive delivery, planning for phased rollouts and MVP releases.
• Excellent documentation skills, with a "documentation-first" mindset for creating clear, actionable design specifications and artifacts.
• Strong collaborative and communication skills, with the ability to effectively partner with cross-functional teams (Product, Engineering, Go-To-Market).
• Experience working in an Agile development environment, understanding iterative design and development cycles.
• Customer empathy and a data-driven approach to problem-solving, using data, simulations, or A/B testing concepts to support design decisions.

Preferred Skills:

• Experience conducting user research, usability testing, and analyzing qualitative/quantitative data to inform design.
• Familiarity with front-end development concepts beyond basic HTML/CSS/JS, such as understanding component-based architectures.
• Experience in a "founding" or early-stage design role within a startup or high-growth company.
• Ability to mentor junior designers or contribute to building a design team and culture.

📝 Enhancement Note: The technical fluency requirement is nuanced: "You don't need to write code, but you must understand how HTML/CSS/JS work." This indicates a need for practical understanding rather than coding proficiency, crucial for effective collaboration with engineers. The emphasis on "documentation-first" and "data-driven problem-solving" aligns with typical requirements for senior operations or product-focused roles where process and measurable outcomes are paramount.

📊 Process & Systems Portfolio Requirements

Portfolio Essentials:

• Case studies demonstrating the complete product development lifecycle, from problem definition to shipped feature, highlighting collaboration with cross-functional teams.
• Examples showcasing how you translated complex problems into simplified user experiences and clear design solutions.
• Prototypes that illustrate user flows, interaction design, and the validation process used to refine designs.
• Documentation samples that reflect a "documentation-first" approach, including detailed specifications, user stories, or design rationale.
• Evidence of building or contributing to a Design System, including component libraries, style guides, and their implementation.

Process Documentation:
