Senior Backend Engineer
About this role
About the Role Backend-focused role centered on scaling Railway's high-throughput systems. You’ll own end-to-end features—from data pipelines to UI touchpoints—focused on billing, fraud, and reliable operations at scale. What You'll Do
- 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.
- Build payment flows that are correct under concurrency and partial failure: idempotent charges, retries, reconciliation, and clean handling of provider edge cases (Stripe and beyond).
- Develop fraud and abuse detection — signal collection, real-time scoring, automated mitigation — that protects platform margin without getting in legitimate users' way.
