Westmount, Quebec, Canada Csc Generation Full-time
CSC Generation is the AI-native holding company re-engineering omni-channel retail. We acquire iconic brands and transform them with Genesis—our operating platform unifying a Data Fabric, Automation Engine, proprietary tools, and shared services—to modernize operations, elevate customer experience, and expand margins. 
With $1B+ in revenue across 13 brands, our portfolio includes Sur La Table, Backcountry, One Kings Lane, and more—premier home and outdoor banners that double as real-world innovation hubs. CSC Generation continues to grow through M&A, revitalizing companies with strong brand recognition and loyal customers. 

We are looking for a Staff Data Scientist to lead the development of production-grade machine learning solutions that drive measurable business impact.

This is a senior individual contributor role requiring deep technical expertise, independent judgment, and the ability to influence cross-functional teams. You will own complex, ambiguous problems end-to-end, from problem framing through deployment and iteration.

Key Responsibilities – Technical Leadership:

    • Lead the design and development of ML systems that solve complex, ambiguous business problems
    • Make sound technical decisions on model architecture, evaluation methodology, and tradeoffs
    • Set standards for model validation, testing, and monitoring across the team
    • Identify when "good enough" is appropriate vs. when deeper investment is warranted
    • Debug and troubleshoot models that fail in production - understand why they fail, not just that they fail

Key Responsibilities – End-to-End Model Development & Evaluation:

    • Frame business problems as well-defined ML tasks with clear success criteria
    • Build robust predictive models (classification, regression, time series, causal inference)
    • Implement rigorous train/validation/test methodology to ensure real-world generalization
    • Identify and prevent data leakage, overfitting, and other failure modes before they reach production
    • Define metrics that align model performance with actual business outcomes
    • Conduct holdout testing on true out-of-sample data - recognize when CV metrics are misleading
    • Design and analyze experiments to measure causal impact
    • Communicate model limitations, uncertainty, and risk to technical and non-technical stakeholders

Key Responsibilities – Influence & Collaboration:

    • Partner with product, engineering, and business teams to ensure ML solutions solve real problems
    • Translate complex technical concepts into actionable recommendations for stakeholders
    • Contribute to hiring and technical interviews

Required Qualifications:

    • MS in a quantitative field (Statistics, Computer Science, Operations Research or related discipline)
    • 7+ years applied ML / data science experience
    • Expert-level proficiency in Python / R, and SQL
    • Familiarity with cloud data & ML platforms (GCP/Vertex AI, AWS/SageMaker)
    • Proven track record of building production ML systems that delivered measurable business impact
    • Deep understanding of model evaluation methodology, experimental design, and causal inference 
    • Ability to work with messy, incomplete, real-world data and make pragmatic tradeoffs
    • Strong communication and influence skills
    • Self-directed and autonomous

Preferred Qualifications:

    • Hands-on experience in e-commerce retail and pricing
    • PhD in a quantitative field
    • Track record of mentoring junior data scientists and leading technical projects

What We're NOT Looking For

    • Someone who only knows how to call .fit() and .predict() without understanding the underlying mechanics
    • Someone who builds black-box models they can't explain, debug, or defend
    • Someone who needs detailed instructions or hand-holding for ambiguous problems
    • Someone who over-engineers solutions when a simple approach would suffice
