Senior Growth Data Scientist

You will own the reliability and quality bar for an AI copilot embedded in an trading platform used by sophisticated investors

You will design and build evaluation systems that measure correctness, safety, latency, and regression risk across market analysis, portfolio/risk reasoning, and trading workflows (including order placement)

You will develop and maintain benchmarks: curated “golden sets,” scenario suites, stress/adversarial cases, and continuously refreshed market/regime-based test corpora

You will build automated quality gates and regression workflows that block releases when key metrics degrade

You will partner with engineering and product to define safe tool/action contracts (deterministic previews, confirmations, auditability) and ensure predictable assistant behavior

You will own model improvement loops tied to evals: data collection/labeling strategies, error taxonomy, prompt/tooling changes, and when appropriate, fine-tuning or preference optimization to measurably improve benchmark performance

You will design and operate monitoring + incident response for AI: telemetry, alerting, RCA, and “fix-forward” processes

You will develop a deep understanding of trading concepts (margin, shorting, portfolio margin, risk, execution) and how to express them accurately and understandably to users Tech Stack: Rust, TypeScript, Postgres, React (Web), React Native (Mobile), observability/telemetry tooling, LLM APIs + model serving, eval/training pipelines

Experience with fine-tuning, preference optimization, distillation, or prompt/compiler-style techniques for improving tool-use reliability

Experience creating domain-specific benchmarks and adversarial suites (e.g., “known-bad” scenarios) for high-stakes applications

Deep experience with trading across asset classes, margin types, etc.

Experience with Rust and performance-sensitive services

Experience designing incident response and SLOs for ML/AI systems
