Software Engineer (Ads Delivery), Brand Ads

Team Overview TikTok's immersive content ecosystem and global scale create unique opportunities for brands to reach users in ways that feel native, relevant, and effective. Our team focuses on building the next generation of Brand Innovation products across Premium Reach and Brand Search areas.

We own critical parts of the end-to-end delivery stack behind these products, from traffic allocation and auction strategy to pacing, bidding, ranking, experimentation, and delivery quality. We work closely with Product, Strategy, Data Science, and cross-functional engineering teams to turn ambiguous business opportunities into scalable product capabilities. This role is not limited to execution. We are looking for engineers who can drive product development end-to-end: identify the right problems, shape technical and product direction, design robust delivery mechanisms, and ship solutions that unlock measurable business impact.

What You'll Build You will help develop delivery systems and product capabilities for a fast-evolving portfolio of brand ads products, including:

• Contextual Ads: Deliver ads alongside highly relevant and premium content with strong controls over supply quality, allocation, and monetization efficiency.
• Brand Search: Build delivery and marketplace capabilities that connect advertiser demand with high-intent search traffic and ranking opportunities.

Responsibilities

• Build delivery systems across pacing, bidding, auction, traffic allocation, and delivery controls.
• Drive products from concept to launch with Product, Strategy, and XFN partners.
• Turn business goals into scalable delivery strategies and system designs.
• Own technical design, implementation, experimentation, launch, and iteration.
• Use data and experiments to diagnose issues and drive fast iteration.

Why Join Us This is a high-impact opportunity to shape how some of TikTok's most strategic brand ads products are delivered and scaled. You will work on real marketplace and systems problems at global scale, influence both product and technical direction, and help define the next generation of delivery capabilities for contextual, search, and content-driven advertising.

If you are excited by auction dynamics, pacing systems, bidding strategy, and end-to-end product ownership, we would love to talk to you.
