About the Position

Senior Software Engineer (Stream Processing)

Amsterdam, Netherlands; Berlin, Germany; United Kingdom

About Nebius

Nebius is leading a new era in cloud infrastructure for the global AI economy. We are building a full-stack AI cloud platform that supports developers and enterprises from data and model training through to production deployment, without the cost and complexity of building large in-house AI/ML infrastructure.

Built by engineers, for engineers. From large-scale GPU orchestration to inference optimization, we own the hard problems across compute, storage, networking and applied AI.

Listed on Nasdaq (NBIS) and headquartered in Amsterdam, we have a global footprint with R&D hubs across Europe, the UK, North America and Israel. Our team of 1,500+ includes hundreds of engineers with deep expertise across hardware, software and AI R&D.

Responsibilities

In this role, you will:

Build stateful streaming pipelines that compute billed consumption in near real time.
Develop and operate Go services that ingest usage events, move data between our storage systems and deliver consumption data to users through usage APIs and billing data exports.
Guarantee correctness under failures: idempotency, exactly-once processing and reconciliation.
Operate transactional storage, persistent queues and change data capture under high throughput.
Build reusable streaming infrastructure rather than solving each use case independently.
Improve the reliability, scalability, latency and observability of the billing platform.
Take end-to-end ownership of your systems: design, implementation, reliability and deployment.

Requirements

We expect you to have:

Strong software engineering fundamentals.
Professional experience building and operating backend, streaming or data-intensive systems.
The ability to reason about consistency and data correctness under failures.
Experience with databases, messaging systems or event-processing platforms.
The ability to investigate unfamiliar systems and solve problems without an obvious predefined solution.
The ability and willingness to learn the team's technology stack.

Nice to Have

It will be an added bonus if you have:

Experience with a stateful stream-processing framework such as Apache Flink or Kafka Streams.
Experience designing streaming pipelines.
Go development experience.
Experience operating services in Kubernetes.

Go, Python
Apache Flink
YDB
