Position

"Love numbers" is one of KAYAK's core cultural values, and being the leading travel search engine worldwide means that we have a lot of numbers and data. Our marketing data science team uses that data to better enable KAYAK to share our product with travelers around the globe- we want to enable everyone to be confident in travel planning.

We’re looking for a Senior Data Scientist to join our team. As a team built on diverse backgrounds, we are looking for an experienced problem-solver to contribute the strengths of their own experiences and expertise. Our ultimate goal is to ask and answer the questions, as well as build the tools, that will let KAYAK confidently scale user acquisition across all of our markets. You will also be working closely with an international team of analysts, engineers, and marketing experts.

This is a “full-stack” data science role. Our team's projects can draw from the following skill sets: assembling data sources from square one, parsing and cleaning data, mining for insights, building and improving models, designing and running experiments, presenting results and giving recommendations to stakeholders outside our team, and driving business decisions or technical changes to our product. 

A sample of projects we work on:

  • Improving the predictive models and control algorithms used by our home-grown bidding platform to make large-scale user acquisition decisions
  • Building data pipelines and reporting solutions to monitor performance metrics across marketing channels
  • Forecasting future KPIs using time series analysis techniques
  • Optimizing budget allocation and investment strategies across channels and campaigns
  • Running experiments to assess the true impact of marketing campaigns
  • User journey analyses, including lifetime value and paths to conversion

This position will be based in our Cambridge office near Kendall Square/Lechmere.

What We're Looking For

  • Ability to write high quality code, especially in Python
  • A storyteller's approach to analysis: not satisfied at "what", but "why?", "how?", and "what next?"
  • Extensive experience with SQL and database usage. Data manipulation and extraction should be a well-honed tool in your toolset
  • Extensive experience with building mathematical models for real-world events/scenarios 
  • Loves problem solving and developing creative, tailored approaches 
  • Great communication skills- capable of bridging business and technology
  • 2+ years of industry experience in a related role
  • Experimental design experience is a plus
  • Online marketing experience is a plus

Voluntary Self-Identification of Disability

Why are you being asked to complete this form?

To help us measure how well we are doing, we are asking you to tell us if you have a disability or if you ever had a disability. Completing this form is voluntary, but we hope that you will choose to fill it out. If you are applying for a job, any answer you give will be kept private and will not be used against you in any way.

If you already work for us, your answer will not be used against you in any way. Because a person may become disabled at any time, we are required to ask all of our employees to update their information every five years. You may voluntarily self-identify as having a disability on this form without fear of any punishment because you did not identify as having a disability earlier.
