The Role

Join our growing Machine Learning, AI & Quantitative Research (MAQR) group as a Senior Data Scientist. MAQR is a small, high-ownership team embedded across a diverse portfolio of businesses — from financial services and insurance to marketplace trading platforms and operations. We don’t have a narrow mandate. We build what needs to be built, ship it to production, and measure what matters.

This role is for a data scientist who is as comfortable wrangling a messy operational dataset as they are designing a production inference pipeline. You bring rigor without rigidity — you know when a logistic regression is the right answer and when it isn’t. You’ve built things that run in the real world, not just in notebooks.

We operate with a startup mindset inside a well-capitalized holding company. You will have real ownership, real clients, and real impact.

Key Responsibilities:

Algorithm to Production

• Own the full model lifecycle: from problem formulation and feature engineering through training, validation, and deployment in a live production environment
• Build and maintain ML pipelines that run reliably — not just models that score well offline
• Instrument models for monitoring, drift detection, and retraining triggers in production systems
• Work closely with engineers to integrate models into product workflows, operational tooling, and client-facing applications

Applied Science & Experimentation

• Develop predictive models, time series forecasts, anomaly detection systems, and causal inference frameworks across varied business contexts
• Design and analyze experiments — from A/B tests to geo-randomized trials — with proper statistical rigor
• Translate ambiguous business problems into well-scoped data science problems; define success metrics before modeling begins
• Review relevant literature and apply state-of-the-art methods where warranted; resist overengineering where simpler approaches perform just as well.

Collaboration & Communication

• Partner with cross-functional teams — business leads, engineers, product managers, and analysts — to deliver solutions aligned with real objectives
• Translate model outputs and technical trade-offs into clear, accessible communication for business stakeholders
• Contribute to AI governance standards and champion responsible, explainable AI practices across client engagements

• Master’s degree in a quantitative field (Statistics, Computer Science, Mathematics, Operations Research, Engineering, or related) plus 6+ years of applied data science experience, OR PhD in a quantitative field plus 3+ years of hands-on industry experience
• At least 6+ years of Python (or equivalent) for data analysis, model development, and production-ready scripting
• At least 4+ years of end-to-end ML model development and deployment — not just training, but shipping to production
• Demonstrated fluency across the data science stack: wrangling, feature engineering, modeling, evaluation, and deployment tooling
• Strong statistical foundations: hypothesis testing, regression, Bayesian reasoning, model validation, and uncertainty quantification
• Proven ability to bring definition and structure to large, ambiguous problems

• Clear communicator who can explain model trade-offs to an engineer and business impact to an executive

Preferred qualifications:

• Experience with cloud platforms and cloud-native ML workflows
• MLOps familiarity: pipeline orchestration, model registries, CI/CD for ML, and inference infrastructure
• Experience with large-scale or real-time data (streaming, event-driven, high-volume batch processing)
• Background in time series forecasting, causal inference, or combinatorial optimization
• Experience in financial services, insurance, marketplace integrity, or operations-heavy industries
• Knowledge of quantitative finance, econometrics, or portfolio methods — useful context, not a requirement
• Ability to write production-quality, maintainable code beyond model scripts
• Experience working Agile with cross-functional, client-facing teams
