About Block Labs

Block Labs is a leading force in the Web3 space, incubating, investing in, and accelerating top-tier fintech, crypto and iGaming projects. With a mission to shape the future of decentralized technology, we partner with visionary startups to raise funding, refine product-market fit, and grow their audiences. 

As we continue our mission of looking for best-of-class talent we are now looking for an ambitious and self-driven Senior Product UI Designer to join our iGaming partner’s rapidly growing team!  

About The Role

One of our most successful partner projects has grown to become the largest crypto poker platform in the world. Their rapid success stems from a commitment to building a fast, secure, and transparent gaming experience that appeals to both professional players and beginners. The platform also set a record for hosting the largest online poker pot in history—an incredible $7,750,000!

We're looking for a game-lover, who can transform concepts into intuitive and engaging user experiences for fast-paced competitive environments. You'll join a growing team of designers, collaborating closely with product owners to create cutting-edge interfaces for a specific iGaming/poker product. 

Key Responsibilities:

• Design high-quality, visually clear interfaces from wireframes to final prototypes
• Create UI that supports engaging user experiences and gameplay flows
• Turn briefs into effective visual designs using color, layout, and hierarchy
• Collaborate with UX designers to refine and elevate early concepts
• Work closely with developers and PMs to ensure smooth implementation
• Help build and maintain a flexible design system for scalable UI
• Use data (like A/B tests or user behavior) to improve designs over time
• Research competitors and propose innovative UI improvements
• Present your work clearly in design reviews and team sessions
• Make sure designs are accessible, responsive, and consistent across devices
• Stay updated on design trends in gaming, Web3, and mobile apps

About You:

• Solid experience in UI Design, backed by a strong portfolio.
• Experience designing for B2C mobile apps.
• Deep understanding of UI principles, responsive design, and best practices across platforms (apps, websites, dashboards).
• Comfortable working with and contributing to design systems.
• Strong technical design skills—attention to detail, component logic, and handoff-ready files.
• Strong communication skills—both written and verbal.
• Ability to design interfaces that are both intuitive and visually engaging.
• Expert in design tools, especially Figma (for both design and prototyping).

Why You’ll Love This Role:

• Design UI for a fast-growing crypto poker platform used by thousands every day
• Turn ideas into polished, high-quality designs
• Work with a team experienced in Web3 and decentralized gaming
• Join a team that cares about great design and continuous learning

If you have a passion for innovation, a keen eye for detail, and a portfolio that showcases your ability to blend aesthetics with functionality, we'd love to speak with you!
