Crossian

Overview of job

ABOUT THE ROLE

At Crossian, data science is not just analytics, it's a strategic lever powering our global eCommerce engine. As we grow from a $200M valuation toward $1B, the Data & AI Team plays a central role in designing models and optimization engines that fuel revenue, efficiency, and growth at scale.

As a Data Scientist, you will translate real business challenges into elegant analytical frameworks and machine learning solutions. From rigorous A/B testing to predictive modeling, from optimization algorithms to supply chain forecasting, your insights and models will directly influence how we acquire customers, plan inventory, price products, and build smarter features. You'll work cross-functionally with product, marketing, operations, and engineering teams to ensure your models are not only technically excellent but also business-relevant and production-ready.

If you're passionate about solving high-impact business problems with data, Crossian is the place to make it happen.

WHAT YOU WILL DO

Business-Framed Statistical Modeling

• Collaborate with stakeholders to translate open-ended business problems into testable hypotheses and ML formulations.
• Develop statistical models (e.g., linear regression, logistic regression, hierarchical models) to understand and predict business dynamics.
• Drive experimentation strategy and analyze A/B tests with proper statistical rigor.

ML Model Development

• Build and validate supervised and unsupervised ML models (e.g., regression, classification, clustering, ensemble methods).
• Apply modeling techniques to problems like customer segmentation, fraud detection, demand prediction, and marketing efficiency.
• Fine-tune models using performance metrics such as AUC, RMSE, lift, and precision/recall.

Optimization & Forecasting

• Apply operations research techniques to build optimization solutions for pricing, inventory, and logistics.
• Contribute to planning tools via time-series forecasting, resource allocation models, or heuristics.
• (Nice to have) Experience applying ML to supply chain use cases (demand forecasting, inventory management, routing).

Cross-Functional Execution

• Work closely with MLEs and Data Engineers to productionize models and integrate into APIs or dashboards.
• Communicate clearly with non-technical partners (Marketing, Product, Finance) to ensure insight adoption.
• Mentor junior team members and contribute to analytics best practices and experimentation frameworks.

We’re not just about building platforms; we’re about creating a workplace where talent thrives. Here's what you’ll gain:

• Exceptional Compensation
  • Total annual compensation $70,000 - $90,000, reflecting your expertise and contribution.
• Growth Opportunities
  • Hands-on exposure to cutting-edge technologies and complex system architecture in a global-scale project.
  • Clear career advancement pathways and access to continuous professional development programs.
• Global Vision
  • Contribute to projects that redefine how brands connect with consumers globally.
  • Opportunity to work on challenging problems in data analytics, customer engagement, and operational efficiency.

In addition to development tasks, you’ll collaborate closely with other CoEs to understand their unique challenges. With your technical expertise, you’ll continuously propose innovative solutions to elevate their performance and contribute to the overall success of the organization.
