Senior Product Engineer, Scalability

This is a backend-leaning role focused on scaling systems. Billing and fraud will be a focus, but your remit spans every high-throughput system at Railway , workers, queues, event pipelines, and the databases underneath them. You'll own your work end-to-end, including when a feature reaches the UI.

For this role, you will:

Architect and scale the pipelines that turn raw usage into accurate, real-time billing , metering, aggregation, rating, and invoicing across millions of events, from ingestion in ClickHouse to the rating engine.
