At Snowflake, we are powering the era of the agentic enterprise. To usher in this new era, we seek AI-native thinkers across every function who are energized by the opportunity to reinvent how they work. You don’t just use tools; you possess an innate curiosity, treating AI as a high-trust collaborator that is core to how you solve problems and accelerate your impact. We look for low-ego individuals who thrive in dynamic and fast-moving environments and move with an experimental mindset — who rapidly test emerging capabilities to discover simpler, more powerful ways to deliver results. At Snowflake, your role isn't just to execute a function, but to help redefine the future of how work gets done. About the role The App Runtime team is building a platform that lets every Snowflake user go from an idea to a live, deployed web application (Node.js first) in minutes. We own the end-to-end experience of building and running apps, from Cortex AI-assisted development to deployment in a secure, scalable infrastructure. Apps built on the platform inherit Snowflake's security, governance, lineage, and access controls by default. See Deploy Faster with Snowflake Apps . As a Staff/Principal Engineer, you will shape the product and its architecture. It’s a high leverage role - you will lead a team to scale and harden an early-stage, public-preview product. Your decisions will have a long-lasting impact on the future of Snowflake as an app platform. This role requires a unique combination of deep hands-on expertise in scalability, performance and security, great product instincts, customer obsession and the organizational influence to drive cross-team programs. Responsibilities Own the roadmap and technical decisions to evolve the public-preview platform into a production-grade one, adding features like horizontal scaling, cost efficiency via suspend/resume, support for stacks beyond Node.js, and stronger access and data-governance controls Stay deeply hands-on by authoring specs

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.

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.
