JOB-2119

A seed-stage, crypto-native company building a high-performance prediction-markets exchange, with an off-chain order book and on-chain settlement, is hiring a Founding Backend Engineer to own its entire backend.

Scope

  • Own the matching engine, blockchain indexer, API and WebSocket services, data schema and platform
  • Build the trader-facing surface: order entry, market data and account state
  • Design end to end: state model, failure modes, recovery and consistency between the order book and the chain
  • Treat infrastructure as a first-class deliverable: Terraform, Kafka, Redis and Postgres operations, observability and on-call
  • Work directly with the founders to shape the product, not just the code

About you

  • 3–10 years in backend or distributed systems at Senior or Staff level (or on a clear promotion track)
  • Production distributed-systems experience: ordering, idempotency, consistency and failover
  • Strong CS generalist across architecture, databases and scaling
  • Depth in a systems language (Rust preferred; C++, Go or Java considered)
  • Exchange, trading or crypto experience, or big tech followed by startup experience, is a strong plus

Hybrid in New York, NY. Open to visa transfers.
