About the Team

DoorDash is building the world’s most reliable on-demand, logistics engine for delivery! We’re looking for experienced engineers to join our fast-growing engineering team to help us develop a 24x7, global infrastructure system that powers DoorDash’s three-sided marketplace of consumers, merchants, and dashers.

And now, with our new São Paulo office, we offer an unique opportunity for fast tracking your career by experiencing an early venture and help DoorDash grow from a small team to one of the largest engineering hubs in the world.

About the Role

We’re looking for Senior Backend Engineers to work on both Product and Product Platform based teams. Product focused Engineers work at the intersection of product and infrastructure to solve key business problems with elegant technical solutions.

• Develop and define the backend architecture and tech stack for a product area
• Improve performance, reliability, scalability and security for our backend systems
• Be involved in transitioning our monolithic codebase to a microservice-based architecture
• Completely disrupt logistics by tackling bleeding-edge, technical problems

We’re excited about you because you have…

• B.S., M.S., or PhD. in Computer Science or equivalent
• 5+ years of industry experience
• Prior experience working with backend tech stacks
• Proficiency in using AI coding tools (e.g., Claude Code, Codex, Cursor) in the full software development lifecycle, including designing, generating code, testing, monitoring and releasing software
• Ability to analyze and improve efficiency, scalability, and stability of various system resources
• Experience with service oriented architecture, writing REST API’s, unit testing, and architectural design
• Understanding of modern web stacks and architecture (HTTP, REST)
• Experience with SQL and NoSQL databases and other technologies (e.g. Postgres, Redis, Elasticsearch, RabbitMQ)
