Build the ML systems behind real-time CTV ad bidding at Pinterest's tvScientific
Own the machine learning powering tvScientific's Connected TV ad-buying platform — real-time bidding, campaign optimization, and incrementality measurement across Hulu, Pluto TV, Disney+, HBO Max, and hundreds of FAST channels. This is production ML in adtech, not research: you'll write prod Python that makes millions of bid decisions per second and prove advertisers' CTV spend actually drove business outcomes.
