About the Role At DoorDash we are redefining what it means to be a designer. We are building towards a team of makers, builders, and doers. Between 2005 and 2015, "web designer" became "product designer" and the scope widened. The same shift is happening now — LLMs are expanding the T again, toward strategy on one end and direct execution on the other. As a Staff Product Designer, you will lead this shift across your team: not just practicing build-first design, but multiplying it through the people and systems around you. We're seeking an ambitious and system design minded Staff Product Designer to lead “Meals for Work” within DoorDash for Business , a strategic area at the heart of redefining workplace dining and company perks. You’ll craft transformative consumer and enterprise experiences, from tools that make team lunch ordering effortless to scalable solutions for catering, company paid recurring meals, and grocery benefits. This role offers a unique opportunity to design powerful systems that help workplace admins plan, manage, and operate food programs with confidence, while pioneering new offerings in an evolving market. This position is open for candidates in San Francisco, Seattle, or New York City, and will report to the Head of New Bets Design within our Consumer organization. You will work in a hybrid model, working from one of our offices 1-2 times a week with the rest working from home. Your primary impact is making the team faster and more autonomous. You build reusable workflows, shared tools, and decision frameworks that let every designer on your team operate at a higher level with less coordination overhead. Your secondary impact is revenue: the speed and quality gains you unlock translate directly into more experiments shipped, faster iteration cycles, and measurable business outcomes across your team and adjacent teams. You're excited about this opportunity because you will... Define projects with a clear point of view on what to build,

About the Role & Team Every AI insight, every experiment, every cohort at Amplitude starts with a query. Our in-house OLAP engine, Nova , processes trillions of events in real time — turning raw behavioral data into fast, trustworthy answers that power decisions for thousands of product teams worldwide. We’re entering a world where AI agents don’t just assist product teams — they ship features, run experiments, and make prioritization calls autonomously. What makes that possible is agents’ ability to verify their work against real product data continuously. That makes Nova the critical infrastructure in the loop, and as non-stop agents become the main source of queries, the demand on Nova’s throughput, correctness, and operational rigor grows dramatically.
