Founded in 2018, Clear Street is a diversified financial services firm replacing the legacy infrastructure used across capital markets. We started from scratch by building a completely cloud-native clearing and custody system designed for today's complex, global market. Our platform is fully integrated with central clearing houses and exchanges to support billions in trading volume per day. We've agonized about our data model abstractions, created horizontal scalability, and crafted thoughtful APIs. All so we can provide a best-in-class experience for our clients. By combining highly-skilled product and engineering talent with seasoned finance professionals, we're building the essentials to compete in today's fast-paced markets.

The Role: - 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 Requirements: - At least Eight (8) years of experience shipping production software; strong proficiency with any programming language - Strong knowledge of computer science fundamentals, testing methodology, and systems design - Experience building evaluation frameworks, test harnesses, and benchmark suites for complex systems (LLMs/agents/search/retrieval/ranking/recommenders) - Experience running model improvement cycles: dataset curation, labeling/QA, offline experimentation, and deploying changes with measurable impact on benchmarks - Ability to define metrics, build measurement pipelines, and drive engineering/product decisions from data - Comfort working across the stack: debugging model/tooling failures, instrumenting services, and partnering with frontend/product on UX patterns that improve safety and trust - High degree of self-motivation and willingness to jump into unfamiliar areas to solve problems Bonus: - 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 We Offer: The Base Salary Range for this role is $180,000 - $250,000.
