Senior Product Designer

About HeyMax HeyMax turns everyday spending into travel. Users earn Max Miles on the things they already buy, and redeem them for flights, hotels, and experiences worldwide. Founded in 2023, we're live in Singapore and Hong Kong — and building toward a product that works for anyone, anywhere in the world. The role — a mini lab inside HeyMax You'll run a growth and expansion design lab: a small, autonomous unit with one mandate — grow HeyMax's user base, anywhere in the world. That means the full growth surface: how new users discover and activate, how existing users deepen and refer, and how the experience flexes for markets and users we haven't designed for yet. You operate like a startup within the startup — pick the highest-leverage problem, ship an experiment, read the data, decide what's next. What you'll own • Global activation — the entire journey from first touch to first value moment, designed to work for any user in any market from day one. This is the engine that lets HeyMax launch a country without rebuilding the product. • One experience, every market — an adaptive design system where the product reconfigures itself around user state and market maturity. You're not designing screens per country; you're designing the rules that make one product serve a hundred markets. • Compounding growth loops — referral, sharing, and re-engagement mechanics built to scale across borders. Every experiment you ship becomes reusable infrastructure for the next market. • The lab's playbook — you set the growth agenda, run the experiment portfolio, and build the repeatable expansion playbook the whole company will run on. Who you are • 5+ years consumer product design, with real growth work — you've owned an activation or acquisition funnel metric, not just designed alongside one. • Systems thinker: you design state machines, not screens. "What does this surface look like with 1 partner / 10 partners" is a question you ask before drawing anything. • AI-native: AI tools are your default for prototyping, research synthesis, and copy variants — you move at lab speed because of it. Bonus: you've designed agent or copilot patterns. • Comfortable with the ambiguity of a market you can't visit — you design research-cheap ways to learn (fake-door tests, concierge MVPs, remote unmoderated tests).
