Software Engineer, C/C++ SDK Performance Optimization
TikTok, San Jose, California
The team
We own the Effect SDK powering TikTok's camera and creation experience — the system behind every filter, AR effect, and visual effect used by hundreds of millions of creators every day. This role sits at the business architecture layer of a self-developed rendering engine, partnering closely with rendering, algorithm, and camera pipeline teams to deliver smooth, low-power effect experiences across a massive range of mobile devices.
What you will do
- Drive end-to-end experience optimization of the effect pipeline during shooting — diagnose and resolve frame drops, jank, thermal throttling, and power consumption issues on real user devices.
