Data Scientist

Job description

Remerge is a fast-growing mobile advertising scaleup that has become the no.1 app retargeting company over the last 5 years with offices spanning Berlin, San Francisco, New York, Singapore, Tokyo, Seoul and Beijing. Our mission is to help app developers maximize user engagement and in-app revenues by providing the world's most scalable and efficient app retargeting platform. Remerge enables app developers to re-engage up to 2 million users per second across 500,000 apps globally in order to increase retention and boost user lifetime value. Remerge works with the world's top grossing app developers from all major verticals such as Wish, AirBnb, Spotify, JollyChic and Grab



Striving to deliver the best return on advertisement spend for our clients by finding the best combination of Ads, targeted users and bidding price, we are looking for a talented data scientist who is adept at crawling through large data sets to find actionable insights and build prediction models. If you are the kind of Data Scientist that would go beyond pure mathematical and statistical modelling to leverage your analytical and creative problem-solving skills to build a product that makes a real impact in the business, then this role would be the perfect challenge for you.   


Going beyond typical AdTech machine learning projects like click through rate and conversion rate predictions, we are aiming further and determine to be a pioneer in delivering incremental Ad results. In practice, you would be thrilled by uncommon challenges such as changing consumer behavior, fraudsters’ actions and auction dynamics, as well as high-cardinality-sparse-data and counterfactual issues, not to mention the engineering decisions when working with multi-terabytes of data.  

The predictive models will be deployed into our low-latency high-throughput system currently handling up to 2M requests per second and collecting over terabytes of data daily. You will work with our experienced engineering team to take your models to production and solve prediction problems at scale.


Besides being skilled in data analytics and predictive modeling, the ideal candidate would have a strong mindset in product ownership which cares about materializing the business impacts through well-thought planning and communications. You should work well in an autonomous culture, which enjoys a high degree of freedom in making decisions but at the same time requires one to be responsible for his/her own time uses. Finally, you should be a good communicator – able to simplify the complex and present your ideas effectively.


Job Responsibilities

  • Gain a deep understanding of our business domain and solutions, work closely with our product team to identify opportunities for improving the algorithmic side of our product;
  • Build and implement machine learning models and prototype solutions for prediction problems in large scale;
  • Work closely with the engineering and infrastructure teams to operationalize the prototypes into high quality production solutions;
  • Proactively analyze data to answer key business questions or out of self-initiated curiosity with an eye for what drives business performance, investigating and communicating areas for improvement in efficiency and productivity, which in turn drives changes in operations or initiatives in product;
  • Conduct investigative research with large data sets, uncover actionable insights and answer product questions essential to the product development process;
  • Actively contribute to improving the data-driven culture at Remerge. 


 You are our ideal candidate if you:

  • have 2-4 years of experience as a Data Scientist developing predictive models related to digital marketing and/or consumer behavior;
  • are a competent Data Scientist having good knowledge in data science theories as well as the technologies. Expertise in Experimental Design, Bayesian Data Analysis, or Tensorflow programming will be a BIG PLUS;
  • are a critical thinker that likes to challenge ideas and assumptions rigorously rather than accepting them at face value;
  • are a good detective that have a super instinct knowing where to look for information to find answers;
  • are excellent in communicating difficult concepts to people of varying backgrounds using common ground, metaphor, sketching and storytelling;
  • are a creative-problem solver who knows how to find a way to get around or over or through an obstacle;
  • are excited when working with complex data science problems;
  • are passionate in advertising technologies and mobile apps.

Our Promise

  • Work with senior engineers who value good engineering practices, lean processes and always strive for the simplest working solution;
  • Make a difference in the development of a successfully proven product that is required by top app developers worldwide;
  • Solve tough algorithmic challenges at high scale unique to the advertising world;
  • Benefit from a competitive remuneration package with generous stock option awards;
  • While operating at huge scale, we still maintain a close-knit team culture with team dinners, activities, and offsite to celebrate our success;
  • Growth and continuous learning: you are encouraged to thrust in experiments and personally grow;
  • We believe in supporting a culture of trust and responsibility, that’s why Remerge employees enjoy a flexible vacation and work from home policy.
