KAYAK is looking for people who love working with data and have a strong interest in machine learning systems, from recommender systems to reinforcement learning to vision to natural language processing. Good candidates will be well-versed in recent advances in machine learning and will be comfortable quickly testing and iterating on new ideas. Positions at different levels of seniority are available.
KAYAK Labs, specifically, is a cross-cutting team focused on riskier projects and innovation across the business. Leveraging ML/AI, optimization, and our unique data assets, we aim for novel, impactful products and breakthrough improvements. We seek to distinguish our brand, to delight our users, and to help our customers experience the world through travel with confidence and peace-of-mind.
As part of the Labs team, you’ll collaborate with strong researchers and engineers, and your work will have tangible impact. You will be challenged; you will have an opportunity to shape our business, and by extension, the wider travel industry. You will expand your competence and explore new technologies at the intersection of AI, data engineering, computation, and product delivery at scale.
Frame, design and execute your own solutions to modeling problems that will improve user experience and/or optimize key metrics important to the business.
Conduct experiments and engage in rapid-prototyping of ideas, making creative use of the data and resources at your disposal.
Implement designs in a stable, maintainable, and scalable production-ready form.
Extract, process and leverage massive amounts of data to drive successful projects.
Engage in group problem-solving, and collaborative team efforts.
Communicate and share results in a clear and concise manner.
Comfortable with math, statistics, systems design and coding to the extent necessary to tackle industrial machine learning and data science challenges. A PhD in a quantitative field (computer science, statistics, mathematics, operations research, science, engineering, etc.), is preferred and is a good indicator of sufficient preparation, but is not strictly required: what you can do (or quickly learn to do) is more important.
Exposure to a minimum introductory level treatment of the core concepts and methods in machine learning, and some applied experience deploying those methods towards solving data science problems.
Familiarity with current machine learning development ecosystems (Python, PyTorch / TensorFlow, Git, etc.)
Comfortable collaborating in a dynamic, cross-functional team: you know how to listen, ask questions, build consensus, advocate (with data), and share success. You are willing to assume leadership and ownership over technological, business, or team responsibilities.
Strong written and verbal communication skills: you can communicate clearly and effectively with peers and non-technical stakeholders alike. You can explain your plan for solving a business problem clearly, and document your work concisely.
Working knowledge of advanced machine learning theory and methods, whether through experience or (graduate) coursework.
Direct experience applying ML/AI in a business environment, and experience distilling high-level business challenges down to concrete modeling problems.
Familiarity with bash scripting, relational databases.
Familiarity with CI/CD tools and procedures, containerization, and horizontal scaling in latency sensitive ML-centric / production inference settings.
Research publication track-record.
