Job Summary
In this role, you will develop scalable event streaming infrastructures using Kafka, optimize their reliability, debug complex system issues, and implement automation-driven solutions.
Job Technologies
Your role in the team
- We're looking for an experienced Platform Engineer to join the Event Streaming team - the distributed team responsible for the Kafka infrastructure and event streaming systems that power business-critical workflows across Wolt, Deliveroo, and DoorDash.
- You'll be joining a team that operates at the intersection of Platform Engineering and Reliability Engineering, building and running the streaming backbone that is used by thousands of services across 3 companies.
- This is deeply technical work: you'll own distributed systems at scale, contribute to long-term architecture decisions, and be working on the reliability of critical parts of infrastructure.
- You'll be joining the team within the broader Storage organisation.
- The team builds and operates highly reliable, scalable and efficient event streaming infrastructure, including Kafka, in-house Event Streaming abstraction (internally called Event Bus) and any future streaming platform technologies.
- These systems support critical 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, Event Bus, and related streaming components.
- Debug complex distributed systems issues - latency issues, performance bottlenecks, capacity constraints, partition imbalances - and drive them to resolution.
- Build infrastructure automation and self-healing capabilities that reduce operational toil and improve platform resilience.
- Contribute to the team's 24/7 on-call rotation and incident response.
- Partner closely with other teams within the Storage organization and the wider Core Infrastructure org, such as SRE, Data Platform, and Caching teams across EU and US regions - including occasional collaboration during EU evening hours.
- Shape the long-term architecture and evolution of our event streaming platform, contributing to RFCs and technical strategy.
