Build and maintain critical data infrastructure pipelines to support a high-throughput, real-time prediction market platform.
Responsibilities
- Polymarket is looking for a Senior Quantitative Developer to join the team that runs the data infrastructure powering our platform — real-time pipelines, clean market data, and reliable delivery across every system that depends on it. The team is small and the surface area is large. Everyone carries meaningful ownership.
- This hire is about adding real depth to a high-performing team working on complex, high-stakes systems. You'll take full ownership of critical pipelines across our data infrastructure — not just keeping them running, but actively making them better, faster, and more robust over time. If you've built and operated high-throughput data infrastructure in production environments where reliability and performance truly matter, this is the role for you.
- Build and maintain real-time data pipelines that ingest market events across our platform with high reliability and low latency
- Investigate and resolve root causes of data gaps, delivery delays, and schema breaks before they compound into larger incidents
- Ship incremental improvements to ingestion and delivery infrastructure on a continuous basis — not just when something breaks
- Monitor pipeline health, define meaningful alerts, and reduce the operational overhead of keeping systems running
- Partner with analysts and engineers to understand how data is consumed downstream and improve the quality and shape of what gets delivered
- Document systems clearly enough that any engineer on the team can context-switch into your systems without friction
Requirements
- 5+ years of experience building and operating production data pipelines with real throughput and real consequences when they fail
- Strong proficiency in Python or a similar language for pipeline development, data transformation, and tooling
- Hands-on experience with stream processing systems such as Kafka, Flink, or Kinesis in a production environment
- Track record of debugging hard data reliability issues — schema drift, late-arriving events, ordering anomalies — and getting to root cause without a lot of hand-holding
- Comfort operating in resource-constrained environments where you own the full lifecycle of what you build, from design through ongoing maintenance
- Experience working with cloud data infrastructure, particularly on AWS or GCP, including storage, compute, and orchestration tooling
- (Plus) Experience in financial markets, crypto infrastructure, or other latency-sensitive trading environments
- (Plus) Familiarity with blockchain event indexing or on-chain data ingestion
- (Plus) Experience building or maintaining data contracts and schema registries across multiple producers and consumers
Conditions
- Competitive salary & equity
- Unlimited PTO
- Full Health, Vision, & Dental coverage
- 401k match
- Hardware setup: new MacBook Pro, big display, & accessories
