We’re looking for a sharp, user-focused UX Researcher to help shape and improve the overall player experience. You’ll act as the voice of the user by conducting research, uncovering behavioral insights, and turning those findings into clear, actionable product decisions.
You’ll work closely with Product, Design, and Data teams, ensuring that product decisions are driven by real user needs and behaviors rather than assumptions.

Competitor & Market Research — Conduct structured competitive analysis of sweepstakes casino products to benchmark our UX against industry standards and identify gaps.
Wireframing & Prototyping — Use Figma or Visily to translate research insights into wireframes, user flows, and low-to-mid fidelity prototypes that guide product and design decisions.
User Personas & Journey Mapping — Develop and maintain player personas, customer journey maps, and mental models that inform product strategy and prioritization.
Cross-Functional Collaboration — Work directly with Product Managers, Designers, and Developers to embed user insights into the product lifecycle from ideation through launch.
Stakeholder Reporting — Document and present research findings clearly to stakeholders, making complex insights accessible and actionable.
UX Standards — Champion user-centered design principles, accessibility standards, and usability best practices across all product initiatives.
Continuous Discovery — Proactively identify new research questions, monitor industry UX trends, and propose process improvements to keep our research function sharp.
2+ years of hands-on experience in UX research, with a portfolio or case studies demonstrating research-to-product impact.
Proficiency in Figma and/or Visily for wireframing, prototyping, and user flow design.
Proven experience conducting user interviews, usability testing, and surveys — both moderated and unmoderated.
Familiarity with analytics and behavioral tools such as Mixpanel, Hotjar, FullStory, or Google Analytics.
Strong analytical mindset — ability to synthesize qualitative and quantitative data into clear, prioritized insights.
Excellent written and verbal communication skills; able to present research clearly to non-research audiences.
Advanced AI user — comfortable leveraging AI tools to accelerate research synthesis, generate interview guides, and surface patterns at scale.
English fluency required.
Experience in sweepstakes casino, online gaming, fintech, or consumer subscription products.
Experience working in fast-paced startup or scale-up environments.
Exposure to game mechanics, reward loops, or player psychology research.
