Ruby Labs

About The Position

Ruby Labs is seeking a UX Lead to drive UX strategy, design quality, and research practices for a high-growth D2C product. This role is crucial for improving retention, activation, and funnel performance. The ideal candidate is deeply technical, data-fluent, and design-strong, with a high-ownership, high-impact mindset. This position is not a standard 9-5 and requires a proactive approach to building systems, leading people, and influencing growth metrics. The current design process involves direct frontend engineering, and UX research needs more structure, which the UX Lead will establish.

Requirements

Strong, hands-on ability to analyze product data independently.
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 (GrowthBook, Optimizely, or similar) end-to-end.
Demonstrated experience driving measurable improvements in retention, activation, or LTV.
Strong understanding of conversion funnels, retention loops, and user behavior at scale.
Background in CRO (conversion rate optimization) or growth-driven design.
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).
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.
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 outcomes, not output.

Nice To Haves

Experience in LegalTech, document tools, or utility products.
Familiarity with TailwindCSS, React/Next.js component implementations — you can review frontend code, not just spec it.
Experience working in engineering-led teams without a separate design org.
Exposure to PDF-based or form-heavy UX flows.

Responsibilities

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.
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, FullStory, 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 (GrowthBook or similar) — hypothesis, implementation, result analysis.
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.
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.
