About the roleOndo operates real-time trading systems that run around the clock across traditional and crypto venues. The platform spans low-latency Rust engines, a fleet of Go services for trading, execution, and PnL accounting, and a multi-region Kubernetes footprint on AWS.
We are looking for an SRE with strong systems programming skills to own the reliability, observability, and performance of this platform. This is a hands-on role: you will read and modify Go and Rust code, debug latency regressions down to the feed handler, run incident response during market hours, and build the automation that keeps a 24/7 trading system healthy with a small team.
Target outcomes- Own production reliability for real-time trading services: trading engines, execution gateways, market data ingestion, and PnL/reconciliation pipelines
- Operate and evolve our multi-region Kubernetes clusters on AWS (EKS), deployed via GitOps (Flux) with SOPS-encrypted secrets
- Build and refine observability: Prometheus metrics and alerting, Datadog logs and dashboards, and the SLOs that catch degradation before it costs money
- Improve deploy safety: progressive rollouts, config-reload behavior, and guardrails that prevent a bad push from touching live trading
Responsibilities- Debug production incidents end to end: stale market data feeds, exchange rate limits, WebSocket disconnects, order-lifecycle desyncs, and latency regressions in the trading path
- Harden market data ingestion from providers such as Databento and venue-native feeds (REST and WebSocket), including staleness detection, failover, and replay
- Build reconciliation and data-integrity tooling across live gauges, Postgres, and our S3 parquet data lake, so positions, fills, and PnL always agree
- Participate in an on-call rotation covering US equity market hours and 24/7 crypto venues
Requirements- 5+ years in SRE, production engineering, or infrastructure roles, with meaningful time supporting real-time or latency-sensitive systems
- Strong programming ability in Go or Rust, and willingness to work in both; this role changes application code, not just infrastructure
- Deep, hands-on Kubernetes and AWS experience: you have run stateful, latency-sensitive workloads in production, not just stateless web services
- Strong observability instincts: fluent PromQL, structured-log analysis, and experience designing alerts with high signal and low noise
- Solid Linux internals and networking fundamentals: you can chase a p99 regression through the kernel, the NIC, or the GC
- Sound judgment under pressure and clear written communication during and after incidents
Nice to haves- Experience operating trading systems, execution infrastructure, or market data infrastructure at a trading firm, exchange, or broker
- Familiarity with market microstructure and order lifecycle (order books, order types, fills and reconciliation)
- Experience with market data providers and protocols (Databento, SIP/prop equity feeds, venue WebSocket APIs)
- Exposure to crypto venues and on-chain trading
- Python for operational tooling and data analysis (pandas, parquet, BigQuery)
- Experience with GitOps workflows, infrastructure as code, and secrets management at scale
