Senior Data Scientist

This is ideally a hybrid role but open to remote.

Role Overview

We are looking for a Senior Data Scientist with a strong can-do mindset, proven ability to ship production-grade models, and passion for solving ambiguous business challenges. This role blends deep technical expertise with business acumen, product thinking, and strong storytelling skills. You will drive end-to-end delivery of Data & AI solutions—from problem framing and data acquisition to model development, deployment, and ongoing optimization—while influencing stakeholders across the organization.

Key Responsibilities

Model Development & Delivery

• Apply advanced analytics, machine learning, deep learning, and AI methodologies to build predictive models and intelligent automation systems that deliver measurable business impact.
• Own the full model lifecycle: data exploration, modeling, validation, deployment, monitoring, and continual improvement.
• Diagnose and resolve model performance issues; implement scalable, reliable processes for ongoing model operations.
• Use strong programming skills to prepare complex datasets (structured, semi-structured, unstructured) and build reproducible pipelines.

Business Impact & Storytelling

• Translate complex analytical findings into clear, actionable insights that influence decision-making at all levels.
• Present recommendations in a compelling narrative that resonates with both technical and non-technical stakeholders.
• Lead discovery sessions to clarify business needs, define success metrics, and design analytical approaches that support business strategy.

Innovation & Best Practices

• Drive innovation in Data & AI through new techniques, experimentation frameworks, and reusable analytical assets.
• Establish and promote best practices in model development, MLOps, governance, and data quality.
• Stay current on emerging trends, regulations, and technologies; provide guidance on how to leverage them within the organization.

Leadership & Collaboration

• Serve as a subject matter expert for stakeholders across the enterprise.
• Partner with cross-functional teams—including Engineering, Product, and Business—to deliver solutions that scale.
• Lead or contribute to strategic initiatives, roadmaps, and business cases that support the organization's data and AI vision.
• Mentor and guide other data scientists; contribute to internal training, tools, and knowledge-sharing.

Execution & Change Leadership

• Manage complex, ambiguous problems by structuring analytical approaches and selecting appropriate modeling techniques.
• Lead change management and communication efforts associated with analytics initiatives.
• Implement processes and controls that ensure high-quality, consistent delivery of analytical work.

Qualifications

• 7+ years of relevant experience in data science, machine learning, or applied analytics.
• Advanced degree (PhD preferred) in Computer Science, Engineering, Statistics, Mathematics, Physics, or related quantitative field—or equivalent experience.
• Proven track record of shipping models to production and maintaining them at scale.
• Expertise in machine learning and deep learning algorithms and frameworks.
• Proficiency in Python and SQL; experience with R, SAS, or other analytical tools is a plus.
• Experience with distributed computing technologies (Hive, Hadoop, Spark) and cloud ML platforms (AWS SageMaker, Azure ML, etc.).
• Strong communication, storytelling, and influence skills; able to drive alignment across diverse groups.
• Demonstrated ability to operate in ambiguity, make data-driven decisions, and solve complex, open-ended problems.
• Experienced collaborator with deep cross-functional partnership skills and ownership mindset.
