Senior Software Engineer, Event Streaming Systems in London

Join us in our mission to transform the way people shop and eat, where impact, innovation and growth drive everything we do. Our Engineering teams tackle complex technical challenges across a global, three-sided marketplace, building and scaling systems that serve millions of customers, riders and partners every day. From real-time logistics to resilient infrastructure and marketplace optimisation, we design, build and operate technology that powers Deliveroo’s growth at scale.

We’re looking for a Senior Software Engineer to join our team. This is a hybrid role. In this role, you’ll help us build and operate the event streaming infrastructure that powers business-critical workflows across Deliveroo, DoorDash and Wolt.

What You’ll Be Doing

• You’ll be joining the Event Streaming Systems team within the broader Storage organisation. The team builds and operates highly reliable, scalable and efficient event streaming infrastructure, including Kafka, Event Streaming abstractions (internally called EventBus) and future streaming platform technologies. These systems support Tier-0 workflows and are foundational to how engineering teams build reliable, event-driven products at scale.
• Design, build and operate large-scale event streaming infrastructure that supports critical production workloads.
• Improve the reliability, scalability, observability and automation of Kafka, EventBus and related streaming platforms.
• Debug complex distributed systems issues, including performance bottlenecks, capacity constraints and production reliability challenges.
• Build infrastructure automation and self-healing capabilities that reduce operational toil and improve platform resilience.
• Contribute to incident response, operational readiness and continuous improvement for Tier-0 infrastructure.
• Partner closely with EventBus, Storage, SRE, Data Platform and Core Infrastructure teams across US and EU regions.
• Help shape the long-term architecture and evolution of Deliveroo’s event streaming platform.

What You’ll Need to Thrive

• Strong hands-on experience building or operating distributed systems in production.
• Experience with Kafka or similar event streaming systems, either as a platform, infrastructure service or critical production dependency.
• Strong coding ability in Java, Go, Python or similar languages, with a focus on reliable, maintainable production systems.
• Experience operating scalable production infrastructure, including debugging, troubleshooting and improving reliability.
• Strong understanding of infrastructure automation, observability, capacity management and operational excellence.
• Good fundamentals in Linux, networking and JVM-based systems, or curiosity to deepen expertise in these areas.
• Strong collaboration and communication skills, with the ability to work across platform, infrastructure and product engineering teams.

Nice to have

• Experience contributing to Kafka or related open source distributed systems.
• Experience with Redpanda, WarpStream, AutoMQ, Pulsar or similar streaming technologies.
• Experience with JVM tuning, broker tuning, partition management or Cruise Control.
• Experience with tiered storage, diskless streaming architectures or multi-region event streaming platforms.
• Experience operating Tier-0 infrastructure at large scale.
