The USDS Global E-Commerce Quality & Engineering Efficiency team is dedicated to elevating the product quality of TikTok's Global E-Commerce ecosystem in the US. We are a group of passionate problem-solvers who drive quality assurance best practices and boost engineering efficiency. Our team is responsible for the end-to-end quality assurance of US e-commerce products, spanning the consumer side, seller side, creator side, and core e-commerce platforms.
We sit at the intersection of traditional quality assurance and platform engineering. Beyond designing test plans and executing test coverage across iOS, Android, Frontend, and Server-side systems, our team is responsible for building engineering efficiency tooling, customizing automation frameworks, and providing direct software engineering and debugging support for various business domains. We deeply integrate with our engineering partners to ensure the rapid, stable growth of our e-commerce platforms.
As a Software Engineer in the Quality & Efficiency (Q&E) team, you will be responsible for building the next generation of AI-driven developer tooling and infrastructure. Your primary mission is to design, develop, and deploy autonomous AI agents and intelligent workflows that eliminate friction and supercharge engineering velocity. This is a software development and systems engineering role focused on building internal platforms, automation tools, and agentic systems, rather than just performing traditional QA testing validation.
Responsibilities
- AI Tooling & Agent Development: Architect, build, and maintain production-grade AI agents, developer productivity tools, and internal efficiency platforms.
- System Architecture: Improve system design and architecture to ensure the high stability, performance, scalability, and reliability of engineering efficiency tools.
- LLM Integration: Implement and optimize agentic workflows, prompt engineering strategies, and retrieval-augmented generation (RAG) pipelines tailored for developer workflows.
- Cross-Functional Collaboration: Partner closely with engineering teams to identify efficiency bottlenecks and deliver high-impact, rapid-prototype, and production-ready solutions.
- Operational Excellence: Own the lifecycle of your tools, including software updates, capability enhancements, robust monitoring, troubleshooting, and on-call support for the internal platforms you build.
Minimum Qualifications:
- Bachelor's degree in Computer Science, Engineering, or a related technical discipline.
- Solid industrial experience with general-purpose programming languages—Python is required for AI/agentic development, and Golang is highly preferred for tooling and infrastructure.
- Strong foundation in Computer Science, including algorithms, data structures, and software design patterns. Excellent problem-solving abilities.
- Deep understanding of data structures, algorithms, and their time/space complexity, alongside practical experience with distributed components like MySQL, MongoDB, Redis, and Message Queues (MQ).
- Proven experience building and deploying AI-driven applications or AI agents. Hands-on familiarity with LLM APIs, orchestration frameworks, and embedding models.
Preferred Qualifications:
- Strong grasp of AI Agent Frameworks, Skill development, and MCP Server Development.
- Strong sense of product ownership and excel at creative problem-solving.
