Frontend Infrastructure Engineer (AI Tooling), TikTok Client Arch

TikTok’s Web Architecture team is looking for a visionary Frontend Infrastructure Engineer (AI Tooling) to shape the future of AI-driven frontend engineering. You will work on the evolution of our monorepo toolchain, web application architecture and frameworks, while integrating LLM-powered automation and intelligent development workflows to build an AI-native frontend infrastructure.



Key Responsibilities:

- Define and prototype what “AI-native frontend infrastructure” means in practice — where both humans and AI agents are first-class users of the development platform and tooling.

- Transform frontend developer experience by leveraging AI to automate and enhance repository maintenance, large-scale refactoring, error diagnosis and remediation, CI/CD automation, and knowledge management across complex codebases.

- Establish evaluation and benchmarking frameworks to measure AI-assisted engineering productivity, reliability, and code correctness at scale.

- Design and build AI-native interaction paradigms, web application architectures, and supporting frameworks that enable AI-driven user experiences.

- Stay abreast of the latest web technologies, trends, and industry practices. Evaluate and recommend new tools, frameworks, and methodologies to enhance the team's efficiency.

- Partner with engineering teams and cross-functional teams to identify challenges, deliver scalable platform solutions, and drive adoption with measurable impact.
