About the role
This is a backend-leaning role focused on scaling systems at Railway. Billing and fraud will be a focus, but your remit spans every high-throughput system — workers, queues, event pipelines, and the databases underneath them.
You'll own your work end-to-end, including when a feature reaches the UI.
What you'll do
- Architect and scale 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.
- Scale Postgres under heavy write load, Node.js services under pressure, and long-running workflows orchestrated with Temporal where exactly-once semantics and durability matter.
- Build TypeScript + GraphQL APIs where correctness and auditability are non-negotiable.
- Write Engineering Requirement Documents to take something from idea, to defined tasks, to implementation, to monitoring its success and scaling it further.
- Contribute to open-source repositories (CLI, Typescript SDK, Railpack, etc.).
- Be oncall from time to time.
- Re-architect billing end-to-end: per-second usage metering at platform scale, idempotent payment processing that survives provider outages without double-charging, and credit, prepayment, and enterprise-invoicing models that hold up under audit.
- Stand up a fraud-detection service that scores signups and deployments in real time and automatically throttles abuse (crypto mining, free-tier farming, stolen cards).
- Scale Temporal workloads to orchestrate workflows across millions of deployments.
- Build internal tooling that gives teams across Railway a trustworthy, real-time view into the systems they depend on.
Nice to have
- Rust experience, or the desire to learn it.
