  • Solid software engineering fundamentals with expertise in Python/R, SQL, AI/ML frameworks, and the modern data science stack
  • A toolkit spanning from classical statistical methods to state-of-the-art ML techniques, with knowledge of how to choose and apply the right tool for each unique problem
  • Proven ability to effectively communicate with and influence stakeholders across the organization, from engineers to executives
  • Ability to thrive in fast-paced environments and balance speed with quality
  • Strong prioritization skills, consistently focusing on high-impact work

  • Collaborate closely with product managers and engineers to identify opportunities where data science can drive product innovation and user value
  • Synthesize complex analyses into actionable insights, presenting compelling data-driven narratives to influence strategic decisions
  • Evaluate and implement cutting-edge data science methodologies and tools, ensuring the team stays at the forefront of the field
  • Partner with data engineers to enhance data pipelines, logging systems, and MLOps practices, creating a robust foundation for advanced analytics and modeling
