Company at a GlanceOpenX is focused on unleashing the full economic potential of digital media companies. We do this by making digital advertising markets and technologies that are designed to deliver optimal value to publishers and advertisers on every ad served across all screens.
At OpenX, we have built a team that is uniquely experienced in designing and operating high-scale ad marketplaces, and we are constantly on the lookout for thoughtful, creative executors who are as fascinated as we are about finding new ways to apply a blend of market design, technical innovation, operational excellence, and empathetic partner service to the frontiers of digital advertising.
OpenX is seeking a Machine Learning Engineer (Data Scientist) to be responsible for designing, executing, and leading critical R&D projects on petabyte-scale datasets. We also seek creative, curious, and tenacious individuals who are capable of employing sophisticated models to solve challenging problems. Where standard linear and logistic regression is expected for rapid prototyping, we further expect solutions to make full use of skills and expertise in cutting-edge applications of Neural Networks, bagged & boosted decision trees, as well as highly customized optimization algorithms. Also of great importance is the ability to interface those models and insights into our ad exchange and related platforms through the use of both off-the-shelf and customized serving and integration platforms.
