Date Posted: 2026-05-15

Experience Level: 5-10 years

Remote Status: Fully Remote

🚀 Role Summary

  • Drive product and business performance by owning UX strategy, design quality, and the research practice as a core growth lever.

  • Leverage deep technical and data fluency to analyze product analytics, identify friction points, and connect UX decisions directly to business metrics like activation, retention, and conversion.

  • Establish and evolve a scalable design system implemented directly in the frontend, setting the visual and interaction quality bar across the product.

  • Build and lead a structured UX research practice, translating qualitative and quantitative insights into prioritized, actionable product decisions.

  • Collaborate closely with Product and Growth teams to design and optimize critical user journeys, including onboarding, paywalls, and retention loops.

📝 Enhancement Note: This role is positioned as a strategic leadership position within the Product and Growth functions, with a primary focus on leveraging User Experience (UX) as a key driver for business outcomes. The emphasis on "data-fluent," "deeply technical," and "design-strong" indicates a highly analytical and hands-on approach to UX, directly tying design efforts to measurable growth metrics. The "not a 9-5 role" and "high-ownership, high-impact" statements suggest a demanding yet rewarding environment for individuals seeking significant influence and responsibility.

📈 Primary Responsibilities

  • Develop and execute comprehensive UX strategy: Define the overarching UX vision and roadmap, ensuring alignment with product and business objectives to drive measurable improvements in activation, retention, and conversion rates.

  • Own the end-to-end user journey: Conduct thorough audits of user flows from acquisition through long-term retention, identifying and implementing optimizations to enhance user experience and engagement.

  • Drive data-informed design decisions: Independently analyze product analytics (Mixpanel, GA4, Amplitude), session recordings, and behavioral data to identify user pain points, validate hypotheses, and inform design iterations.

  • Lead A/B testing initiatives: Define hypotheses, design experiments, implement tests using platforms like GrowthBook, and rigorously analyze results to validate UX changes and their impact on key growth metrics.

  • Establish and evolve the design system: Define, enforce, and scale a clear, consistent, and high-quality design system, ensuring its direct implementation in the frontend for efficient and cohesive user interface development.

  • Lead and mentor design and engineering talent: Direct the work of designers and frontend engineers involved in UI/UX, setting clear expectations for quality, defining the "definition of done," and fostering a culture of design excellence.

  • Build and structure the UX research practice: Establish a systematic approach to UX research, including defining priorities, conducting user interviews, surveys, and usability tests, and translating findings into actionable product recommendations.

  • Collaborate cross-functionally: Partner closely with Product Management, Engineering, and Growth teams to integrate UX insights and design solutions into the product development lifecycle.

  • Define analytics instrumentation needs: Proactively collaborate with the data team to define and implement new analytics tracking and reporting requirements to better measure UX impact and user behavior.

📝 Enhancement Note: The responsibilities highlight a hands-on role where the UX Lead is expected to not only strategize but also execute, particularly in data analysis and A/B testing. The emphasis on "implemented directly in frontend, not Figma-first" suggests a need for collaboration with engineers and potentially a deeper understanding of frontend development realities than a traditional design-centric role. The leadership aspect is clear, with expectations to "lead and direct designers and frontend engineers."

🎓 Skills & Qualifications

Education: While no specific degree is mandated, a strong educational foundation in Design, Human-Computer Interaction (HCI), Computer Science, Psychology, or a related field is highly beneficial.

Experience: 5-8+ years of progressive experience in UX, Product Design, or design leadership roles, with a significant portion within fast-paced, growth-oriented environments.

Required Skills:

  • Data Analysis & Interpretation: Proficient in independently analyzing product analytics using tools like Mixpanel, GA4, Amplitude, or similar platforms. Ability to conduct cohort analysis, retention curve analysis, and identify patterns from raw data to form actionable hypotheses.

  • A/B Testing Expertise: Demonstrated experience designing, implementing, and analyzing A/B tests using platforms such as GrowthBook, Optimizely, or similar experimentation tools.

  • Growth & Conversion Optimization: Proven track record of driving measurable improvements in key growth metrics including activation rates, retention, LTV, and conversion rates. Strong understanding of conversion funnels and retention loops.

  • Design Leadership & Systems: Experience leading or managing designers, setting design direction, reviewing work, and elevating team quality. Ability to define, enforce, and evolve a scalable design system.

  • UX Research Methodologies: Proven ability to conduct qualitative and quantitative user research, including user interviews, surveys, and usability testing. Skill in translating research findings into clear, actionable product decisions.

  • Frontend Collaboration: Comfort working in environments where design is implemented directly in the frontend. Ability to collaborate effectively with frontend engineers and understand implementation constraints.

  • Communication & Storytelling: Ability to clearly articulate the "why" behind design decisions, backed by data and user insights, to stakeholders at all levels.

  • Systems Thinking: Capacity to design scalable patterns and solutions rather than isolated screens, considering the broader product ecosystem.

  • Ownership Mindset: A strong sense of accountability for outcomes, not just output.

Preferred Skills:

  • Experience in LegalTech, document management tools, or utility-focused products.

  • Familiarity with frontend technologies such as TailwindCSS, React, or Next.js, with the ability to review frontend code.

  • Experience working within engineering-led teams that may not have a dedicated, separate design organization.

  • Exposure to UX flows involving PDF manipulation or complex form-heavy interactions.

📝 Enhancement Note: The emphasis on "hands-on ability to analyze product data independently" and "you pull your own funnels, you don't wait for reports" strongly suggests that candidates must be self-sufficient in data analysis. The preference for experience where design is "implemented directly in frontend" and familiarity with specific technologies like TailwindCSS and React/Next.js indicates a practical, engineering-adjacent approach to design execution.

📊 Process & Systems Portfolio Requirements

Portfolio Essentials:

  • Data-Validated Design Case Studies: Showcase 2-3 in-depth case studies detailing your process from problem identification through to solution implementation and measured impact. Each case study must clearly articulate the business problem, your role, the design process followed, the data and research used to inform decisions, and the quantifiable business outcomes achieved (e.g., % increase in activation, % improvement in retention, reduction in funnel drop-off).

  • Growth & Optimization Focus: Highlight projects where you directly influenced key growth metrics (activation, retention, conversion, LTV). Demonstrate your understanding of conversion funnels, onboarding flows, and retention loops.

  • Design System Examples: Include examples of your involvement in defining, implementing, or evolving design systems, showcasing your ability to ensure consistency and scalability in design.

  • Cross-functional Collaboration Evidence: Provide examples demonstrating your ability to work effectively with product managers, engineers, and data analysts, illustrating how you integrated their input and communicated your design rationale.

Process Documentation:
