Jobs in Helsinki, Finland

About the role

We're looking for an experienced Platform Engineer to join 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.

What you'll bring

• Strong hands-on experience building or operating distributed systems in production.
• Deep 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 — with the emphasis on building reliable, production-grade systems and libraries.
• 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 communication and writing 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.
• Our Commitment to Diversity and Inclusion
