Job summary

Nebius, Amsterdam-based leader in AI cloud infrastructure, seeks a Senior Software Engineer to design and operate event-processing pipelines that turn product usage into revenue. You’ll build and maintain stateful streaming systems, ensure correctness under failures, and own end-to-end delivery of billing data and APIs.

You'll work with Go/Python, Kubernetes, and streaming tech such as Flink, Kafka Streams, and modern storage solutions, while improving scalability, latency, and observability

Qualifications

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

Responsibilities

• 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.
