About this project

We are building a next-generation advertising platform that embeds products directly into visual experiences rather than traditional banners or feeds. This involves high-scale data pipelines, real-time decisioning, attribution, partner integrations, and performance-critical systems, paired with compelling, visual user experiences.

This is an early-stage initiative in which senior engineers will play a key role in defining the system architecture, technical direction, and engineering standards.

Your technical knowledge is matched only by your passion for designing, creating, and succeeding with others.

You want to build on your experience. You are interested in making a big impact, but you may currently be limited in your growth potential. Join us, and you will work directly with our talented engineering team to push our product to new heights.
