Developers are the heroes of the gaming world.

Without your creativity we wouldn't have Mario, we'd be deprived of Master Chief and Zelda would be nothing more than a twinkle in someone's eye. We want to help you succeed and build a business around your great ideas. We love working with you, we love telling your stories, and we love making a difference in your business.


Small Company, Big Impact

We're a rapidly growing startup, building a technology platform that helps mobile game developers acquire more users, monetize more effectively, and make data-driven decisions. Each month, we reach 600 million people and power 20 billion game sessions in every corner of the globe. We're looking for game changers who want to help others, tackle big problems, and have fun doing it.

In addition to competetive pay and equity in one of the most successful startups around, we offer:

  • 20 days of PTO, and 10 paid holidays (including your birthday!)
  • $130/mo in commuter benefits to offset costs for parking or public transit.  An additional $250/mo can be expensed for Taxi/Uber/Lyft/SideCar or Parking to help get you to/from the office.
  • Fully paid medical, dental, and vision plans for employees and 95% paid for spouses and dependents.
  • Catered breakfast on Mondays, lunch on Tuesdays and Fridays and dinner every evening (you're certainly not expected to eat dinner at the office, but if you're still working at 6:00, you shouldn't do it hungry).  Plus, fully stocked kitchens with snacks and drinks on every floor.

Our technology stack includes Hadoop, Hive, HDFS, HBase Spark, Scala, Python, Java, Jenkins, Scalding, multiple NoSQL storage systems, AWS, Git, Jenkins, Zipkin and Puppet. Our developers own both unit and integration tests to ensure high quality in our products. You have the opportunity to evaluate new technologies and use them to design better and more reliable systems.

We work at massive scale, handling 10s of thousands of events per second and  work with hundreds of TBs of data.  Our products reach over 600 million people around the globe every month so we have tons of great opportunities and challenges to sink your teeth into as an Engineer, whether your focus is Front End, Back End, Data Science/Machine Learning, Analytics or anything in between.

    I have been working at Chartboost full-time


    * Salary is (at least IMO) very fair. * People are extremely professional (in terms of being offensive vs. courteous). We can poke fun at ourselves and people here generally have a good sense of humor, but I never see anyone being horribly ridiculed for gender/race/sexuality (which happens more often than you think at startups usually.) * Free lunch every day! * Managers (or at least my manager) go out of their way to make sure you are happy, succeeding and performing well. You don't feel neglected, held out to dry, or held to ridiculous standards. * PTO policy is awesome. * The recruitment process was easy and smooth. I felt welcome immediately and I never had second thoughts about joining. From what I can gather most new hires who came after me also feel happy with that process and the onboarding process.


    * People leave often. A new person leaves basically every week. I imagine this is partially due to the fact that in this industry people don't stay at places for very long, but it makes me concerned that there aren't any growth opportunities, or that it's difficult to grow, although from what I've witnessed first-hand, Chartboost does seem comfortable promoting people from within. So, take this with a grain of salt. * There is a general gossipy sense to the office which is to be expected with any medium-large startup with lots of young people (median age here is about 30) but it can get a little irritating. * Sometimes it seems like there are too many internal meetings, many of which are not useful to the majority of people in the room. It would be ideal to pare these meetings down so that people only go to the ones that are relevant to their departments.

    Advice to Management

    Make sure that employees continue to feel valued and that we have clear paths to grow our career HERE.

    Average Interview


    I applied online. I interviewed at Chartboost.


    Had a chat with the recruiter, they were very well informed and then scheduled an interview pretty quickly. A general technical telephonic screen, with the interviewer explaining about the role and then we jumped into a coding problem in coder pad. The interviewer explain about the company and about their role in the company in a detailed fashion.
