  • Lead end-to-end UX/UI design for complex, cross-functional product initiatives, setting the highest standards for visual craft and interaction design.

  • Own and shape the customer experience (CX) roadmap, translating customer feedback and user research into actionable design strategies and impactful solutions.

  • Drive strategic UX evolution by partnering closely with product management, engineering, data teams, and business stakeholders to achieve measurable design outcomes.

  • Extend and refine the company's design system, ensuring scalability, accessibility, and consistency across multiple product delivery channels.

  • Provide informal leadership, mentorship, and design direction to junior and mid-level designers, fostering a culture of design maturity and excellence.

📝 Enhancement Note: While the role is titled "Lead UX/UI Designer," the responsibilities and required experience (7+ years, leading complex initiatives, influencing product direction) indicate a senior individual contributor role with significant strategic influence, rather than direct people management. The focus on "Product Design" and "User Experience Operations" aligns with how operations professionals support product development cycles through design excellence and process refinement.

📈 Primary Responsibilities

  • Lead the complete design lifecycle for intricate product initiatives, from initial discovery and hypothesis generation through to final delivery, encompassing multiple customer segments and delivery channels.

  • Translate complex and ambiguous problem spaces into clear design hypotheses, strategic directions, and high-impact, user-centered solutions.

  • Champion evidence-based design practices by actively shaping user research questions, defining key success metrics, and developing robust measurement plans in collaboration with product and data teams.

  • Produce comprehensive design artifacts, including detailed user flows, information architecture, wireframes, high-fidelity UI mockups, and interactive prototypes, utilizing Figma at an expert level.

  • Facilitate complex stakeholder alignment sessions through clear rationale, compelling storytelling, and structured communication methods such as workshops, recorded demonstrations (Looms), and detailed walkthroughs.

  • Ensure all delivered design work adheres to the highest standards of visual craft, interaction design, accessibility (including WCAG familiarity), and overall usability.

  • Provide informal leadership, direction, and constructive feedback to junior and mid-level designers, consistently uplifting the team's design quality, consistency, and overall maturity.

  • Conduct regular design critiques, share best practices, and coach team members on systems thinking, UX fundamentals, and data-driven iteration techniques.

  • Partner with Product Managers, Engineers, and Data Analysts to meticulously define success events and measurable UX outcomes, leveraging analytics tools like Heap to validate assumptions and inform iterative design processes.

  • Extend and refine the existing design system with scalable, accessible components, design tokens, and reusable patterns, creating clear documentation to ensure consistency across product teams.

  • Identify opportunities for design convergence across different products to enhance user interface coherence and operational efficiency.

  • Collaborate with user researchers or independently conduct lean user testing, including usability studies, concept validation exercises, and rapid experimentation to gather actionable insights.

  • Translate research insights directly into design decisions and iterate designs based on customer feedback and performance data.

  • Work closely with engineering teams throughout the development process, providing support, clarifying specifications, and collaborating on quality assurance (QA) to maintain design integrity.

  • Maintain highly organized and well-structured Figma files, employing clear naming conventions, versioning hygiene, and detailed notes for efficient collaboration and handoff.

📝 Enhancement Note: The responsibilities emphasize a hands-on, senior design role with strategic input. The inclusion of "data-driven design," "analytics tools," and "metrics-driven iteration" highlights the operational aspect of design, where success is measured and optimized. The focus on design systems and cross-product coherence also points to operational efficiency and standardization.
