Lead Software Engineer, Programmatic Advertising

Meet CarGurus—the #1 visited online car shopping website in the US. At CarGurus, we’re building the world’s most trusted and transparent automotive marketplace where it’s easy to find great deals from top-rated dealers. 

Founded in 2006 by Langley Steinert (co-founder of TripAdvisor), CarGurus is a technology company with a passion for data and its power to simplify every aspect of the car shopping experience. Using proprietary technology, search algorithms and innovative data analytics, we provide unbiased validation on pricing, dealer reputation and vehicle history.

Our team solves a variety of unique challenges, from designing complex data structures and algorithms to machine learning and mining big-data.  We deploy code daily and use data to drive our decisions, while delivering software and analytics to consumers and dealers around the world.

One of our core beliefs is that useful data will lead to the best outcomes. We make decisions based on our data and insights. Each engineer manages their own products and projects. The autonomy in engineering is something we are very proud of and work hard to maintain. There will be great projects that can be both challenging and long term.

  • Create tests and infrastructure to support continuous delivery of everything you build.
  • Work with data scientists to improve the effectiveness of our ad spend.
  • Implement a testing framework for rapid iteration of A/B tests.

 Who You Are:

  • 10+ years of programming experience.
  • A strong analytical or mathematical background, leveraged in previous roles.
  • Experienced with multiple datastores (SQL, Elasticsearch, MongoDB, etc).
  • Interested in processing large sets of data.
  • Committed to developing well-tested code.
  • Familiar with Java or similar object-oriented language.
  • Previous experience in advertising, real-time bidding, or other high-frequency / low-latency verticals is a plus

CarGurus Culture:

At the core of our company culture is a spirit of innovation, curiosity and collaboration. True to our start-up roots, we’re nimble, flexible and hardworking. We have a great respect for testing and learning and a healthy aversion to scheduling meetings to discuss meetings. Lunch is catered daily. Gym membership is free. Foosball and ping pong are played often. Now a publicly-traded company, we’re as committed as ever to cultivating the culture that got us here.

In addition to the US, CarGurus operates sites in Canada, the UK and Germany with other markets on the horizon. Our offices are located in Cambridge, MA, Detroit, MI and Dublin, Ireland. If you’d like to learn more, please visit our careers page.
