Description
Liberty Mutual's US Retail Markets Data Science Excellence team is seeking a Senior Director I, Data Science to serve as a senior individual contributor and thought leader across our Claims & Service data science portfolio. This is a high-impact advisory role designed for a seasoned practitioner who thrives on breadth — someone who can engage credibly across a wide range of modeling initiatives simultaneously, elevate the technical rigor of our teams, and help translate data science investments into measurable business outcomes.
This role sits within the broader USRM Data Science (USDS) community and will partner closely with front-line DS managers, modeling teams, and business stakeholders to ensure our AI work is grounded in sound methodology and aligned to strategic priorities.
WHAT YOU'LL DO
Technical Advisory & Quality Assurance
- Serve as a senior technical reviewer across active modeling projects, identifying structural risks before they become production problems — including data leakage, label construction errors, distribution shift, and flawed evaluation methodology.
- Challenge assumptions at the design stage: scrutinize feature selection rationale, target variable definitions, train/test splits, and deployment contexts to surface gaps in problem framing.
- Conduct focused reviews of model documentation, validation approaches, and monitoring frameworks; provide specific, actionable feedback rather than general guidance.
- Recognize when a modeling approach is fundamentally misaligned with the underlying business question and redirect teams toward higher-value formulations.
Strategic Business Partnership
- Partner with front-line DS managers and their teams to assess opportunity areas — translating ambiguous business problems into well-scoped modeling applications with clear value hypotheses.
- Help business stakeholders understand what data science/AI can and cannot do in their domain; build shared frameworks for prioritizing investments based on feasibility and expected impact.
- Bridge the gap between technical execution and business strategy by framing model outputs in terms of operational levers, cost/benefit tradeoffs, and downstream claims or service workflows.
- Serve as a sounding board for DS leaders navigating build-vs-buy decisions, vendor evaluations, and model governance questions.
Mentorship & Community Leadership
- Mentor data scientists and senior modelers across USDS — providing technical expertise, business acumen, and systems thinking in roughly equal measure.
- Help develop the broader DS community's shared standards: code review practices, modeling documentation norms, reproducibility expectations, and peer review culture.
- Act as a visible senior leader in Liberty Mutual's DSPRG community — con
