We are looking for a result-driven Mid-to-Senior UI/UX Researcher to help our team drive conversion improvements across our web product. In this role, you’ll analyze user behavior across the full funnel, conduct competitor and market research, and turn insights into high-impact experiment ideas that directly influence product and business outcomes.

This is a fast-paced, product-focused role where your primary focus will be on audits and hypothesis generation rather than design execution. You’ll work with a high level of ownership, consistently delivering well-structured, data-backed ideas to fuel our experimentation roadmap and support continuous growth.

• Conduct systematic competitor and market research across SaaS, subscription, and freemium products — analyzing user flows, paywalls, onboarding funnels, and conversion patterns.

• Mine quantitative data from analytics tools (Mixpanel, Microsoft Clarity, GrowthBook) to identify drop-off points, attention gaps, and underperforming screens.

• Analyze heatmaps, session recordings, and attention data to surface CRO opportunities.

• Deliver 10–15 experiment ideas per week, each scored using the ICE framework (Impact × Confidence × Ease) with a target threshold of 500+.

• Write clear, testable hypotheses with defined success/failure criteria and primary metrics.

• Create low-to-mid fidelity wireframes (AI Tools) to communicate test variants — clear enough for developers and stakeholders to act on.

• Develop user personas, journey maps, and usability assessments specific to our funnel stages (Landing → Start → Quiz → Analyzing → Email Capture → Checkout).

• Present insights and recommendations in twice-weekly Growth team brainstorming sessions.

• Analyze post-test results and extract reusable patterns for the team's knowledge base.

• Stay current on CRO, behavioral psychology, and SaaS conversion trends.

• Research Experience: 3+ years in UX research — you've personally run competitor audits, heuristic evaluations, usability studies, and behavioral data analysis (not just visual design).

• Funnel&SaaS Background: Proven experience with subscription-based or freemium products — you understand recurring revenue funnels, paywalls, and trial-to-paid flows (not just ecommerce/retail).

• Analytical Toolkit: Fluency with heatmaps, session recordings, and A/B test platforms

• Prioritization Rigor: Working knowledge of ICE/PIE or similar frameworks for scoring and ranking experiment ideas.

• Wireframing Ability: Can create low-fidelity prototypes to communicate test concepts.

• Data Fluency: Comfortable pulling insights from Mixpanel, Google Analytics, Hotjar, or Microsoft Clarity.

• Communication: Clear, structured communicator who can present ideas to the team twice a week and document findings for stakeholders.

• Portfolio: Case studies that demonstrate research process and insights — not just final UI designs.

• Experience in a fast-paced startup or growth team where speed and volume of experimentation matter.

• Familiarity with behavioral psychology principles (anchoring, loss aversion, social proof, urgency).

• Basic understanding of front-end implementation - enough to know what's easy vs. hard to build.

• Experience with AI-assisted research tools and methodologies.

• Background in EdTech, HealthTech, or self-improvement products.
