Staff Software Engineer, Application Delivery

About the Team The Storage organization builds and operates the online stateful systems and abstractions that DoorDash Engineering depends on: reliable, efficient, secure, and easy to use. Within Storage, the Distributed Key Value team owns the storage platform that powers business-critical workloads across DoorDash, Wolt, and Deliveroo. These systems sit on the Tier-0 critical path. They serve millions of QPS across multiple regions and underpin how hundreds of engineering teams build reliable systems at massive scale. About the role DoorDash's storage abstraction platform is a unified data-access layer that sits in front of our databases and decouples application teams from the underlying storage engines, similar to modern data-gateway and key-value / time-series data-abstraction platforms. Nearly every request that touches persistent data flows through it. As DoorDash scales 10x–100x across new verticals, global expansion, and acquisitions, this platform is where the hardest distributed-storage problems live — latency at the tail, request routing, and reliability under exponential load. We're hiring a Staff Software Engineer to be the domain specialist for the storage abstraction platform: a deep, opinionated technical leader who owns the reliability, performance, and correctness of the platform at scale, sets its technical direction, and raises the execution bar across the storage organization. You must be located in the New York Metro Area, Bay Area or Seattle for this hybrid position. You will report to the Engineering Manager on our Distributed Key Value team within the Storage organization. You're excited about this opportunity because you will… Own the reliability, performance, and correctness of the storage abstraction platform at scale, independently leading resolution of mission-critical issues in ambiguous, high-pressure situations. Set technical direction for the platform — the storage abstraction and data-access layer, provider model, caching, and rou

We expect all team members to actively engage with AI tools relevant to their role and grow their fluency as the technology evolves. AI experience requirements vary by role and will be assessed during the interview process. We're looking for seasoned full-stack software engineers to join Gusto's HR Experience team. Half the American workforce works at a small business, and most of those businesses can't afford a real HR team. When they hit an HR decision they don't have the expertise for — a termination, a comp change, setting a time-off policy for the first time — they either pay for expensive outside help or guess, even though the right answer depends on rules that vary across 50 states and hundreds of localities. HR Experience is building that expertise directly into Gusto: compliant HR guidance and documentation, built natively for both the employer creating it and the employee receiving it, in a domain where the compliance bar is real — "mostly right" isn't good enough. You'll also help drive the other half of HR Experience's mission: using AI to make Gusto's human HR Partners faster and more effective, so more small businesses can get real HR support without needing to hire their own HR team. As a Staff Software Engineer, you'll operate across th
