What you'll do
- Design, build, test, deploy and improve backend services for customer-facing features used by restaurants and their guests in markets around the world.
- Own features end to end, from technical design through to launch and ongoing support, including taking part in an on-call rotation to keep systems reliable.
- Work on hard problems in data, latency and scale: unifying guest identity across channels, real-time availability search across thousands of venues, and integrations with the systems restaurants already run.
- Build on DoorDash's global platform, so the features you ship can reach restaurants across DoorDash, Deliveroo and Wolt markets rather than being rebuilt for each one.
- Work in a modern engineering environment with frequent daily releases, feature flags and AI coding agents used across code review, deployment and debugging.
- Partner with engineers, product managers and designers across London and other DashOS locations to decide what to build and how.
What we're looking for
- 3+ years of professional software engineering experience, and a degree in Computer Science or a related field, or equivalent practical experience.
- Built and operated backend services or web applications in production, with strong fundamentals in data structures, algorithms and system design.
- Fluent in at least one modern backend language (we mostly use Python), and happy to pick up new languages and tools as the platform evolves.
- Care about the people using what you build, and take ownership of technical solutions from first design to production.
- Use AI coding tools as part of how you work, or are keen to, and comfortable reviewing and taking responsibility for what they produce.
- Enjoy collaborating with cross-functional teams to solve problems that don't have an obvious answer yet.
