Senior Software Development Engineer - Global E-commerce
Responsibilities
The e-commerce industry has seen tremendous growth in recent years and has become a hotly contested space amongst leading internet companies. With millions of loyal users globally, we believe TikTok is an ideal platform to deliver a brand new and better e-commerce experience to our users. Our quality assurance engineering team is responsible for keeping an e-commerce ecosystem stable, secure, and intuitive for our users. We are looking for passionate and talented people to join us as we drive the future of e-commerce here at TikTok.
Role Overview:
We are developing a software quality platform that applies AI to strengthen how code changes are reviewed, tested, and validated before reaching production.
The objective is to improve correctness and reliability by:
- Applying AI-assisted review and analysis to code changes;
- Generating realistic synthetic test data;
- Enforcing clear quality gates across different testing stages;
- Reducing regressions and increasing confidence in production deployments.
This role focuses on designing and implementing systems that enable AI to support quality decisions, while deterministic checks and policies remain authoritative.
Key Responsibilities:
- Develop mechanisms for generating synthetic test data that reflect production structure, scale, and relationships without using real production data.
- Build AI-assisted systems for test generation across unit, integration, and end-to-end testing.
- Define and enforce expectations around correctness, regressions, and behavioral changes.
- Ensure AI-generated outputs are explainable, traceable, and safely bounded.
- Improve the reliability and signal quality of automated testing outcomes.
Scope of Work:
You will contribute to a platform where:
- Build and ingest synthetic test data mirrors production-like characteristics while remaining safe and compliant.
- AI powered system which makes code review, unit tests, integration tests and end to end testing easy and productive.
- Evaluate test results against consistent quality criteria before promotion to later environments in deployment pipelines.
- Failures are summarized and explained in a way that supports efficient resolution.
