Category: Product Design / UX / Growth Operations

Date Posted: May 26, 2026

Experience Level: 5-10 years

πŸš€ Role Summary

  • This is a high-impact, high-ownership remote role focused on leveraging UX as a core growth lever for a high-growth D2C product.

  • The role requires a deep technical understanding, data fluency, and strong design skills to drive product and business performance.

  • You will own UX strategy, design quality, and the research practice, directly influencing key business metrics like activation, retention, and conversion.

  • This position is ideal for someone who wants to build systems, lead people, and is driven by measurable outcomes in a fast-paced environment.

πŸ“ Enhancement Note: This role is positioned as a critical driver of business growth rather than a traditional support function. The emphasis on "growth lever" and "measurable growth" suggests a strong alignment with Revenue Operations and Sales Operations principles, focusing on optimizing user journeys to directly impact key business performance indicators. The "not a 9-5 role" and "high-ownership" descriptors indicate a demanding yet rewarding environment for ambitious operations professionals.

πŸ“ˆ Primary Responsibilities

  • Develop and execute comprehensive UX strategy: Define and own the end-to-end user journey, from acquisition through long-term retention, focusing on improving activation, retention, and conversion rates.

  • Drive measurable growth through UX initiatives: Translate UX efforts into quantifiable improvements in key business metrics, acting as a core driver of product and business performance.

  • Lead data-driven design and optimization: Analyze product analytics independently using tools like Mixpanel and GA4, identify friction points from session recordings and heatmaps, and define hypotheses for A/B testing.

  • Establish and evolve a scalable design system: Define, enforce, and maintain a clear, consistent design system, with a focus on direct frontend implementation rather than a Figma-first approach.

  • Build and structure the UX research practice: Establish priorities, conduct user interviews, surveys, and usability tests, and translate research findings into actionable product decisions.

  • Collaborate closely with Product and Growth teams: Design and optimize critical user flows including onboarding, paywalls, and retention loops to enhance user engagement and monetization.

  • Define and communicate analytics instrumentation needs: Work with the data team to ensure necessary tracking and reporting are in place to measure UX impact effectively.

  • Validate UX changes through experimentation: Design, implement, and analyze A/B tests using platforms like GrowthBook to continuously improve user experience and business outcomes.

  • Lead and mentor designers and frontend engineers: Set the definition of done for UI/UX work, uphold visual and interaction quality standards, and guide team members involved in design and implementation.

πŸ“ Enhancement Note: The responsibilities heavily emphasize a data-centric approach to UX, directly linking design decisions to business outcomes. This aligns with the core principles of Revenue Operations and Growth Operations, where understanding user behavior and optimizing conversion funnels are paramount. The expectation of independent data analysis and A/B testing experience is critical for success in this role.

πŸŽ“ Skills & Qualifications

Education: While no specific degree is mandated, a strong portfolio demonstrating relevant experience and skills is paramount. A background in design, human-computer interaction, or a related field is beneficial.
