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.

As Business Associate for Lyft Business, you'll drive growth and expansion within your existing book of business in a market where transportation touches nearly every part of daily life. Success here isn't just about closing deals; it's about the judgment to identify where your time has the biggest return, and the strategic thinking to advise each client like a trusted partner as you grow their business with us. This job rewards people who think critically about where to focus their energy. Priorities will evolve, systems are still maturing, and you won't always have a playbook for every situation, but you'll have the experience and confidence to navigate ambiguity and make an impact as we figure it out. The people who thrive here are the ones who are resourceful, hard to rattle, and genuinely motivated by finding the right product fit for a client, especially when a conversation gets complex or unexpected. You'll focus on expanding and deepening relationships with small and mid-sized businesses, becoming a Lyft product expert who can efficiently resolve common support issues and guide clients through solutions that fit their needs. In this hybrid role, you will balance inbound and outbound outreach, but with a sharper eye toward prioritization: identifying key decision makers and influencers within your top accounts, and focusing your energy where it will drive the most growth.
