About the role
Scrambly's mobile and web products are used by millions of people worldwide. As our Lead Product Designer, you'll own product design end to end: the vision, the standards, the craft and the outcomes. This is a hands-on leadership role. At first, you'll design core experiences yourself while setting our design direction. As we grow, you'll hire and lead an in-house design team. You'll partner closely with Product and Engineering leadership, turning business goals, metrics and user needs into a product people love to use every day.

What you'll do
• Own the experience. Take full responsibility for UX and UI across all mobile and web products, and make the final call on design decisions.
• Drive discovery. Work with Product to understand users through research, data, funnels and session replays, then turn insights into prioritized hypotheses.
• Experiment fast. Design low-effort experiments and A/B tests with Product and Engineering, learn quickly and iterate without dropping quality.
• Set the craft bar. Deliver flows, prototypes, high-fidelity designs and interaction specs, with pixel-perfect execution on everything we ship.
• Build the system. Create and own Scrambly's design language, components and patterns so design stays fast and consistent across platforms.
• Be the voice of the user. Represent design in leadership discussions and challenge product or technical decisions that hurt the experience.
• Lead the function. Manage external partners (agencies, UX writers, researchers), and hire, mentor and grow the internal team as we scale. What you bring
• 7+ years in product design, with extensive experience on mobile-first consumer products.
• A world-class portfolio showing exceptional UX/UI craft,



strong product thinking and end-to-end work shipped at scale.
• Experience as the sole or lead designer with full ownership of design decisions.
• Hands-on experience with user research, usability testing, hypothesis-driven design, rapid prototyping and A/B testing.
• Experience leading or mentoring designers, or managing agencies and external partners.
• The ability to move fast without losing quality, turning ambiguous problems into simple, elegant solutions.
• Confidence presenting and defending your work with leadership and cross-functional teams.
• Skill with animation, transitions and microinteractions, and practical use of AI tools in your design workflow.
• A strong ownership mindset and comfort in a fast-paced, metrics-driven startup.
• English at B2 or above. Nice to have
• Hands-on use of product analytics tools such as Mixpanel, Amplitude or PostHog.
• Experience building or scaling a design system across multiple platforms.
• Advanced motion design skills.
• A strong network in the design community.
• A background in mobile apps, gaming, rewards, fintech or marketplaces.

What we offer
• A founding leadership role shaping a general product used by millions.
• Full ownership of product design, from vision to execution.
• The chance to build the design team from scratch.
• Direct collaboration with Product, Engineering and company leadership.
• A fast-paced environment where ideas ship quickly.
• Competitive compensation and flexibility. Is this you? This role isn't for designers who prefer isolated features or pure visual execution. We want a design leader who owns ambiguous problems, makes independent calls and is accountable for outcomes.
