[Hiring] Senior UX Researcher @Ruby Labs

Role Description

We're building and scaling a high-growth D2C product used by hundreds of thousands of customers globally. We move fast, ship often, and every product decision needs to be grounded in real user data, not assumptions.

We're looking for a Senior UX Researcher who can build and run a proper research practice, both qualitative and quantitative, and directly connect findings to conversion, retention, and funnel improvements. You'll work closely with Product, Growth, and design leadership to ensure we make smart, data-backed decisions across every part of the product.

This is not a passive observation role. You'll be expected to set the research agenda, design and run studies independently, synthesize insights, and advocate for change with measurable impact. If you're excited by ownership, fast shipping, and seeing your research ship into product within days, read on.

Key Responsibilities

• Set and own the research agenda, define what we research, why, and in what order, in collaboration with Product and Growth leadership.
• Design and run structured research programs, including user interviews, usability tests, surveys, diary studies, and in-product feedback mechanisms.
• Analyze session recordings, heatmaps, and behavioral data (Clarity, Mixpanel) to identify friction and patterns.
• Conduct competitor research to benchmark best practices and identify differentiation opportunities.
• Define and track quantitative research metrics, not just qualitative impressions.
• Translate findings into clear, prioritized recommendations that product and design can act on immediately.
• Help design A/B test hypotheses grounded in user behavior research.
• Build and maintain a research repository structured, searchable, and regularly updated.
• Proactively identify gaps in analytics instrumentation and work with the data team to fill them.
• Help establish research as a core practice in the org, set standards, frameworks, and processes others can follow.

Qualifications

• 4-6+ years of UX research experience in a product company, not an agency.
• Proven track record of running both qualitative and quantitative research end-to-end.
• Experience designing and running user interviews, usability tests, and surveys independently, from question design to analysis to recommendations.
• Strong experience analyzing user behavior using session recording tools (Clarity, Hotjar, FullStory) and product analytics (Mixpanel, GA4, Amplitude, or similar).
• Ability to synthesize qualitative and quantitative data into actionable, prioritized insights.
• Experience running customer surveys that generate statistically meaningful results.
• Strong understanding of conversion funnels, A/B testing, and iterative optimization processes.
• Excellent written and verbal communication, you present research clearly to non-researchers and advocate for both the user and the business.
• Demonstrated ability to operate independently and drive research projects from question to outcome.

Nice to have

• Experience working on D2C SaaS or subscription-based products.
• Background in behavioral psychology, customer journey mapping, or user onboarding optimization.
• Familiarity with CRO (conversion rate optimization) tools and frameworks.
• Experience building a research practice from scratch or in an early-stage team.
• Experience mentoring or guiding junior researchers.
