About the Job

Requirements

  • Deep, hands-on experience delivering predictive models, decision science, causal inference or experimentation in complex environments.
  • Practical capability across agentic workflows, large language models and retrieval-based solutions.
  • A strong command of fairness, explainability, technical assurance and responsible AI controls.
  • Working knowledge of MLOps or LLMOps and what it takes to operate AI reliably through its lifecycle.
  • The judgement to influence senior stakeholders, make sound technical calls and explain complexity without hiding behind jargon.

Responsibilities

  • Shape technical plans with engineering, product and business partners, surfacing dependencies and trade-offs early.
  • Set the technical direction for assigned use cases and select fit-for-purpose modelling, experimentation, retrieval and agentic approaches.
  • Design models and agent workflows with eligibility, suitability and vulnerability safeguards built in from the start.
  • Lift quality through strong data practices, leakage prevention, temporal validation, calibration, experimentation and fair treatment across customer segments.
  • Build and run evaluations that demonstrate quality, human oversight and safe fallback before release recommendations are made.
  • Embed AI risk, privacy and security controls, with clear documentation of assumptions, limitations, approvals and material technical risks.
  • Diagnose drift, model issues and agent failures with engineers, then validate fixes and recovery.
  • Coach AI professionals, strengthen review quality and personally deliver the most complex technical work.

Desired Qualifications

  • Business lending, wealth, credit risk or pricing decision-science experience is valued, but is not essential if the candidate can learn the domain quickly.
