Data Science Engineer

Jampp, Buenos Aires or Córdoba, Argentina

Mobile App Engagement, Retargeting, & User Acquisition

Jampp is a performance marketing platform for mobile advertisers with challenges that span many technologies, from an extremely scalable and highly available platform to big data tools that allow us to manage the big stream of data. We manage hundreds of instances buying impressions in a global market 24/7 with data centers in 3 continents, processing 150 TB daily, 850K QPS and 55+ billion in-app events per month. In order to pick the best ads and show them to the right people at the right time, we rely on real-time machine learning models (with billions of features) that predict in less than 1ms as well as optimization systems which solve complex constrained problems to maximize global company goals in an iterative fashion.

Jampp is the programmatic platform of choice for the fastest growing on-demand companies worldwide.

In 2013, we noticed the chaos surrounding mobile performance advertising and wanted to change it, somehow. We built a suite of growth products that unlock programmatic advertising for some of the biggest names in mobile (like Uber, Rappi, iFood, & Postmates to name a few).

We’re a team of builders - engineers, data architects, designers, and entrepreneurs - who love what we do.

We serve a global customer base from our offices in San Francisco, Berlin, São Paulo, Singapore, and Buenos Aires.

About Jampp

Our Story In 2013 we noticed the chaos surrounding mobile performance advertising, and wanted to change all that, somehow. It took us a year to build Jampp. What we recognized back then resides at the core of everything we do today: real value in this industry is derived from long-lasting app customers, and nothing else. While companies flocked to sell app installs, we designed our infrastructure and technology with a single mission in mind - to help companies boost their mobile sales. Today Jampp uses advanced developments like Predictive Bidding to serve a global client base from offices in San Francisco, London, Berlin, São Paulo, Cape Town and Buenos Aires. We are a diverse team of 80 people with backgrounds spanning Engineering to Economics, delivering sales and engagement to the world’s fastest growing app companies.
