  • Collaborate with cross-functional teams - product, ML, data engineering, frontend, and analytics - to define clear API contracts and translate requirements into scalable technical solutions
  • Mentor and coach engineers on best practices, MLOps principles, GraphQL patterns, and production ML integration
  • Contribute to the long-term technical roadmap, driving innovation and reducing technical debt
