The Role

As a Senior ML Engineer for AWS and Real-Time Inference, you'll own the fast path: ingesting live trading data and scoring it in near real time. It's a systems-heavy role focused on streaming, low-latency inference, and the retraining cadence that keeps models current and most directly determines whether the systems keep up with live markets.

What you'll do:

• Streaming and storage pipelines that feed both model training and low-latency inference.
• The online inference path and its latency. A real-time detector microservice is built and unit-tested but not yet deployed — it needs to be connected to a run-time model and hold latency under live load. One known, non-trivial problem lives here: batch scoring ranks across a whole population, but single-account (or single-wallet) real-time scoring has no population to rank against, so it must threshold on calibrated raw scores.
• The model retraining cadence as data and labels accumulate, including drift-triggered retraining.
• Productionizing new features and detectors on the fast path, in partnership with data science.
• Strong data / ML engineering experience with streaming systems (e.g., Kafka / Kinesis / MSK) and modern data storage formats
• Experience building low-latency, high-throughput inference services
• Proficiency in a systems language (e.g., Go) alongside Python
• Production AWS experience
• Familiarity with financial market data or trading protocols a plus — the US feed is a FIX 5.0 SP2 drop-copy session with real-world quirks (nanosecond timestamps, repeating groups, dedup semantics)
• Familiarity with chain-data infrastructure (node providers, subgraphs, event indexing) is a plus
