Jon San Agustin
Product Designer
I’m Jon San Agustin, a Senior Product Designer with a strong track record of delivering scalable, user-centered solutions across complex digital products. With a foundation in operations at high-growth startups like Postmates and Lyft, I bring a unique blend of business acumen, systems thinking, and executional craft to every project.
Since transitioning into design in 2019, I’ve led end-to-end initiatives—from research and strategy to high-fidelity execution—helping teams ship impactful products that balance user needs with business goals. I specialize in simplifying complexity, designing for clarity, and collaborating cross-functionally to move fast without compromising quality.
