Senior Software Engineer - GenAI , Ads Creative & Ecosystem

A "creative" is the ad (in the form of a short-form video) served to TikTok users, composed of video, background music, call-to-action card, post-click landing page, and other formats that get delivered to users. A quote goes "creativity is the soul of advertising", because a good ad creative is effective, yet difficult to produce, especially at the scale of TikTok advertising.

TikTok Ads Creative & Ecosystem team tackles the challenge of creating engaging and effective ad creatives at scale. Our mission is to build cutting-edge tech solutions for ad understanding, production, and optimization, empowering advertisers, creators, and partners to deliver the best creative experiences.

The team is building platforms to provide in-depth and unique AI-driven data insights to provide creative guidance to advertisers, which is the key for their ads planning and iteration. We are looking for an engineer leader with strong data application background to join our fast growing team. The engineer leader will lead the team to focus on creative insights direction, grow business understanding, build highly scalable and reliable software/infrastructure, partner across functions with global teams, and make big impacts. If you are someone who welcomes challenges, we are eager to have you on the team!
