Job Description

Senior, Staff AI Model Engineer

Clear Street

• 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

  • Strong knowledge of computer science fundamentals, testing methodology, and systems design

  • 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

• Build AI agent discovery on top of Delinea's existing cloud discovery rather than standing up a separate inventory, covering Microsoft Azure today and expanding to AWS and Google Cloud as the platform adds those clouds. • Build discovery for AI agents running on endpoints, a newer surface for the team. • Assess the security posture of discovered agents: how they are configured, what they can access, and where they create risk. • Feed discovered agents and their context into our identity and attribution layer so they can be governed. • Partner closely with the platform teams whose discovery services your work builds on.
