Senior UI Designer

We are ARB Interactive, the team behind Modo Casino, one of the top Social+ platforms in the US. Founded in 2022, we've grown to nearly 200 team members and were named one of LinkedIn's 2025 Top 50 Startups in the United States. We move fast, think big, and love bold ideas that push boundaries (and buttons). From new rewards to fresh game mechanics, every challenge is a chance to innovate and have fun doing it. Our culture is collaborative, curious, and full of laughter because great ideas grow best between coffee, code, and a few epic high-fives.

ARB Interactive is seeking a Senior UI/UX Designer to lead design efforts across our suite of products. This role will own the end-to-end design process for one or more product verticals, working closely with product managers, engineers, and other stakeholders to create compelling user experiences that drive engagement, conversion, and retention. The ideal candidate combines strong visual design skills with a strategic mindset and deep empathy for users.

Experience in mobile UX/UI design is required, and familiarity with gaming, real-money gaming, or sweepstakes mechanics is strongly preferred.

• Lead the UX and UI design for one or more Modo product teams, from concept to launch and beyond.

• Translate product vision and user needs into elegant, functional, and engaging user interfaces.

• Own and evolve the design system to ensure consistency, scalability, and brand alignment across all surfaces.

• Conduct user research, usability testing, and competitor analysis to inform design direction.

• Create wireframes, prototypes, interaction flows, and high-fidelity mockups with a strong attention to detail.

• Collaborate closely with product managers, engineers, and marketing to ensure designs are feasible, optimized, and aligned with product goals.

• Advocate for the user and help shape product strategy through user-centered design thinking.

• Contribute to team culture and mentor junior designers by sharing best practices, feedback, and thought leadership.

• Ensure accessibility and performance are considered in all design output.

• Participate in sprint planning, design reviews, and product brainstorming sessions.

• Proactively identify user experience issues and propose thoughtful solutions based on data and research.

• Maintain clear design documentation and specifications to support handoff to engineering.

• Work with cross-functional stakeholders to iterate quickly and efficiently based on user feedback and evolving requirements.

• Partner with analytics and product teams to validate design hypotheses through testing and experimentation.

• 5+ years of experience in UI/UX design, with a strong portfolio demonstrating end-to-end product design on mobile platforms.

• Deep understanding of mobile interaction patterns, user behavior, and best practices for iOS and Android.

• Proficiency in Figma (or similar tools) for design, prototyping, and collaboration.

• Experience working in social or gaming products; real-money gaming or sweepstakes experience is a strong plus.

• Ability to balance business needs, technical constraints, and user empathy in your design approach.

• Strong communication skills and the ability to clearly articulate design rationale to both technical and non-technical stakeholders.

• Experience working in agile, cross-functional teams and comfort in a fast-paced, iterative environment.

• Bachelor’s degree in Design, HCI, or a related field preferred.
