About

About the Team Are you passionate about using machine learning to improve Customer Experience? Would you like to work in the fast‑paced, competitive, customer‑focused, and data‑rich world of online travel? Our Machine Learning and Data Science team is growing! We are looking to hire researchers and data scientists interested in breaking new ground to tackle some of the most complex customer experience problems in the travel domain. What You'll Do Design & Implement ML Solutions: Take ownership of the end‑to‑end ML lifecycle for your projects, from ideation and research to deployment and monitoring. Test, Learn, and Iterate: Design and analyze tests to validate your models and quantify their business impact and design future iterations. Collaborate and Communicate: Partner closely with product managers, engineers, and business stakeholders to understand requirements, define problems, and communicate your findings and results effectively. Who you are Experience & Education: PhD or MS in a quantitative field (e.g., Computer Science, Economics, Statistics, Physics). 3+ years of hands‑on industry experience building and deploying machine learning models to solve real‑world problems. Functional & Technical Skills: Expertise in applied ML: deep, practical knowledge of machine learning theory (supervised/unsupervised learning, deep learning) and statistical modeling and a strong command of experimental design (A/B testing) and causal inference to accurately measure impact. Able to design end‑to‑end ML solutions: framing the problem, choosing data sources, selecting algorithms, and defining evaluation strategy. Experience with the machine learning software development lifecycle, including experimentation, deployment, monitoring, and iteration in production. Strong programming skills in at least one major ML language (e.g., Python, Scala, Java) plus SQL; writes clean, modular, maintainable code. Technical Fluency: Strong programming skills in Python and its data science ecosystem (e.g., pandas, scikit‑learn, pySpark), plus proficiency in SQL. Follow software engineering best practices and contribute to the team’s shared codebase. First‑Principles Problem Solver: Skilled at dissecting ambiguous problems and clearly communicating complex technical ideas. Highly Desired Experience: Domain knowledge in customer service, recommendation systems, operational applications of ML, and/or e‑commerce. Experience with reinforcement learning or other advanced ML techniques is a plus. Experience building and deploying models using GenAI/LLM technologies. Experience translating research and academic papers into improved model designs and techniques. Minimum Qualifications Bachelor’s degree in Computer Science or a related technical field; or Equivalent related professional experience. 5+ years of relevant professional experience. Proven ability to design end‑to‑end ML solutions, including problem formulation, identification and preparation of data sources, algorithm selection, feature engineering, evaluation strategy, and production deployment and monitoring. Strong programming skills in Python and its data science ecosystem (such as pandas, scikit‑learn, PySpark) and proficiency in SQL, with experience following software engineering best practices and contributing to shared codebases. Familiarity with AI‑driven systems, tools, or workflows and applying AI/ML concepts to real world products, including experience with the machine learning software development lifecycle from experimentation through operational monitoring. Preferred Qualifications MS or PhD in a quantitative field such as Computer Science, Economics, Statistics, Physics, or a related discipline. 3+ years of hands‑on industry experience building, deploying, and iterating on machine learning models that solve real‑world problems in production environments. Proven ability to design end‑to‑end ML solutions, including problem formulation, identification and preparation of data sources, algorithm selection, feature engineering, evaluation strategy, and production deployment and monitoring. Strong programming skills in Python and its data science ecosystem (such as pandas, scikit‑learn, PySpark) and proficiency in SQL, with experience following software engineering best practices and contributing to shared codebases.
