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 the company’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 the company, DoorDash and Wolt.

Get to know our Engineering team, what drives us, how we work, and what you can expect.

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.

Here’s what your day-to-day might look like:

• 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 the company’s event streaming platform.

Our ideal candidate will bring strong expertise in some of these areas and curiosity to grow in others:

• 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.

• 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.

At the company, you’ll do work that matters, solving real-world problems in a three-sided marketplace that’s constantly evolving. We’re food lovers, problem solvers, community builders and more, brought together by a shared drive to make things better. Working here you can expect to:

• Solve meaningful problems at real scale.
• Work on a complex, always-on marketplace that impacts millions every day.
• See your impact, fast.
• Ship, test and improve ideas quickly in a low-hierarchy, high-ownership environment.
• Grow through challenge and ownership.
• Take on big, ambiguous problems and accelerate your career with strong support.
• A culture built for builders.
• High standards, collaboration, flexible working and continuous learning.
• Share in the success you help create.

We aim to create a fair process that lets your skills shine, our interview typically includes 3-4 stages. Explore our Engineering Interview Guide to help you feel confident at each stage.
