Minimum Qualifications:

• Bachelor's degree in Computer Science or a related technical field; or Equivalent related professional experience.

• 2+ years of relevant professional experience.

• Experience applying machine learning, statistical modeling, or related quantitative methods to technical or product problems, with ownership across a service, product area, or defined technical domain from problem formulation through evaluation and delivery.

• Strong programming and data analysis skills, including experience with machine learning methods, model evaluation techniques, and relevant development tools.

• Working knowledge of system design, low-level design, API design, and data modeling as they relate to integrating machine learning capabilities into products.

Preferred Qualifications:

• Advanced degree in machine learning, computer science, statistics, mathematics, economics, operations research, engineering, or a related technical discipline.

• Experience or strong domain interest in airlines, travel marketplaces, revenue management, yield management, pricing, or commercial decision science.

• Experience operating machine learning models or data products at scale, with attention to reliability, monitoring, maintainability, and responsible performance.

• Practical exposure to experimentation or causal-inference methods, such as controlled experiments, quasi-experimental designs, or treatment-effect estimation.

• Experience working with large datasets; familiarity with distributed computing frameworks such as Apache Spark is a plus.

• Familiarity with AI-driven systems, tools, or workflows and applying AI/ML concepts to real-world products.
