About The RoleAs a Lead Product Designer at Scrambly, you will fully own the product design function end-to-end and be responsible for the quality, consistency, and impact of the user experience across all mobile and web products used by millions of users worldwide.
This is a hands‑on leadership role. In the initial phase, you will personally design core product experiences while defining Scrambly’s design vision, strategy, standards, and culture. Over time, you will build and lead an internal product design team and scale the design function as the company and product portfolio grow.
You will act as a strategic partner to Product and Engineering leadership, translating business goals, product metrics, and user needs into clear, user‑centered design solutions. You will have full ownership over design decisions and will be expected to proactively identify problems, propose solutions, and continuously raise the quality bar across the organization.
Your goal is to establish a world‑class product experience and turn Scrambly into a product people genuinely 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.
