About the Role
We're building and scaling a high‑growth D2C product used by hundreds of thousands of customers globally, and we're now entering a phase where UX is a core growth lever. We need a UX Lead who can drive that. This is not a 9–5 role. It's a high‑ownership, high‑impact position for someone who wants to build systems, lead people, and directly influence growth metrics.
What You'll Do
UX Strategy & Growth Impact

Take full ownership of UX, design quality, and user journeys across the product.
Turn UX into a measurable growth lever — directly improving activation, retention, and conversion.
Work closely with Product and Growth to design and optimize funnels, onboarding, paywalls, and retention loops.
Audit and continuously improve the end‑to‑end user journey — from acquisition through long‑term retention.

Data & Analytics (Core Strength)

Analyze product analytics independently — Mixpanel funnels, cohort analysis, retention curves, drop‑off patterns.
Connect UX decisions directly to business metrics — activation rate, retention curves, LTV, conversion.
Define hypotheses, experiments, and success metrics for every UX initiative.
Use session recordings (Clarity, Full Story, Hotjar), heatmaps, and behavioral data to identify friction points.
Proactively request and define new analytics instrumentation and reporting needs with the data team.
Validate UX changes through A/B testing (Growth Book or similar) — hypothesis, implementation, result analysis.

Design Leadership

Define, enforce, and evolve a clear, scalable design system (implemented directly in frontend, not Figma‑first).
Lead and direct designers and frontend engineers involved in UI/UX work — set the definition of done.
Set the visual and interaction quality bar across the product.

UX Research

Establish a structured research practice — define priorities, run interviews, surveys, and usability tests.
Translate raw research into prioritized, actionable product decisions.
Direct and level up the existing UX researcher on the team — provide structure, frameworks, and clear priorities.

What We're Looking For
Core Strengths (Must Have)
Data & Analytics

Strong, hands‑on ability to analyze product data independently — you pull your own funnels, you don't wait for reports.
Deep experience with Mixpanel, GA4, Amplitude, or similar product analytics tools.
Ability to read cohort and retention data, identify patterns, and build hypotheses from raw numbers.
Experience designing and running A/B tests (Growth Book, Optimizely, or similar) end‑to‑end.

Retention & Growth Expertise

Demonstrated experience driving measurable improvements in retention, activation, or LTV.
Strong understanding of conversion funnels, retention loops, and user behavior kground in CRO (conversion rate optimization) or growth‑driven design.

Design Leadership

Strong design background with a portfolio of conversion‑oriented, data‑validated work.
Experience leading or managing designers — you've set direction, reviewed work, and raised team quality.
Ability to define and maintain a consistent, high‑quality design system.
Comfortable working in environments where design is implemented directly in frontend (no Figma‑first culture).

UX Research

Proven ability to collect both qualitative and quantitative user insights.
Experience designing and running user interviews, surveys, and research frameworks.
Ability to translate research into clear, actionable product decisions.

Experience & Mindset

5–8+ years in UX, Product Design, or design leadership, ideally in D2C, SaaS, or consumer digital products.
Experience working in fast‑paced, growth‑oriented environments with daily or near‑daily releases.
Systems thinker — designs scalable patterns, not one‑off screens.
Clear communicator — explains the why behind every design decision with data.
Strong ownership mindset — owns…
