Senior Software Developer, SEM and Analytics

Cambridge, MA
Are you a passionate engineer able to solve hard problems? Do you want a role that allows you to implement your solutions and have a direct impact?
We need a Sr. SEM Engineer who will improve the efficiency and scope of our customer acquisition efforts. On a daily basis, you will analyze site usage and help shape development priorities. The Sr. SEM Engineer will be excited to stretch and apply their skills by solving hard problems, developing heuristics and algorithms. Our customer acquisition is accomplished via search engine marketing (SEM), display ads, and re-marketing. Our SEM campaign has tested over 50M keywords, of which about 500K are being actively shown and growing. Some of the important problems in this space that need to be solved are in keyword discovery, efficient bidding, and revenue attribution.

The Sr. Engineer should be able to talk intelligently about the statistics of testing (e.g. confidence in the result of an A/B test), write SQL queries, use regressions, and be comfortable working with messy real-world data. You will use code languages(or tools) such as Ruby on Rails (RoR), R, AWK, MySQL. We use many languages and are open to the right tool for the right project. We are a data-driven company; we track everything. Converting data to insights is the art and the challenge. Insights backed by data drive the direction the company takes. Your ability to collaborate and communicate effectively will be key to success in this role.

Our Approach:
  • We don't write tech specs - we don't expect you to either.
  • We push new code daily, and hold ourselves to our own coding standards.
  • We brainstorm new ideas, throw them at the wall, and analyze data to determine what sticks.
  • We're reshaping online car shopping just like our TripAdvisor experience revolutionized travel.

  • Experience with Ruby on Rails or other dynamic language (Python, PHP, etc)
  • Strong with algorithms and data structures
  • Proficiency with SQL
  • Proven experience with Search Engine Analytics, Big Data, and SEM
  • Knowledge of R, Awk, and machine learning are all pluses.
