AI Agent Engineer - Global Security Organization
Responsibilities
The mission of TikTok's Global Security Organization is to build and earn trust by reducing risk and securing our businesses and products. Also known as "GSO", this team is the foundation of our efforts to keep TikTok safe, secure, and operating at scale for over 1 billion people around the world. We work to ensure that the TikTok platform is safe and secure, that our users' experience and their data remains safe from external or internal threats, and that we comply with global regulations wherever TikTok operates.
Trust is one of TikTok's biggest initiatives, and security is integral to our success. In whatever ways users interact with us - whether they're watching videos on their For You page, interacting with a Live video, or buying products on TikTok Shop - GSO protects their data and privacy, so they can have a secure and trustworthy experience.
The GSO provides industry-leading security and privacy services to Bytedance, guided by four principles: trust and transparency, business enablement, risk-informed decision-making, and proactive risk reduction. We strive to build sustainable, world-class security capabilities.
SecOps Validation Team (STOV) is responsible for the tools and technologies that support the TikTok infrastructure. STOV oversees technical validation, security operations, and drives engineering enhancements, including the deployment, configuration, and maintenance of security technologies across various domains.
STOV team is building domain specific AI applications to scale GSO's technical control compliance abilities. This role will work closely with STOV's product security to build AI agents which integrate with TikTok's CI/CD pipeline, providing TikTok product and development team with shift-left technical control review and implementation instructions.
As the AI agent engineer, you will be responsible for the entire agent development lifecycle. Your core focus will be on building robust and effective agents that deliver tangible value to our users.
- Use-Case Scoping and Design: Collaborate with product and design teams to identify high-impact use cases for AI agents. Define agent capabilities, goals, and success criteria based on user needs.
- Tool Integration and Development: Design, build, and maintain the APIs and functions that agents use to interact with the world. This includes integrating with ByteDance internal services, APIs, and creating GSO customized tools from scratch.
- Planning and Orchestration: Develop the core logic that allows agents to reason and create effective plans. You will implement and refine orchestration patterns, whether using ByteDance internal AI frameworks or by building custom agent runtimes.
- Reliability and Safety: Implement robust guardrails and safety mechanisms to ensure agents operate predictably and securely. This includes error handling, retry logic, and preventing unintended actions.
- Evaluation and Testing: Create comprehensive evaluation frameworks and automated testing suites to measure agent performance. You will define and track key metrics to drive continuous improvement.
- Memory and Retrieval-Augmented Generation (RAG): Implement and optimize memory systems that allow agents to learn from past interactions. You will build and fine-tune RAG pipelines to provide agents with relevant, up-to-date context from knowledge bases.
- Performance and Cost Optimization: Analyze and optimize the latency, token usage, and computational cost of agent operations. You will balance performance with accuracy to ensure a scalable and cost-effective system.
- Observability and Monitoring: Instrument agents with detailed logging, metrics, and tracing to provide deep visibility into their reasoning processes and actions. You will build dashboards and alerts to monitor agent health and performance.
- Collaboration and Communication: Clearly articulate complex technical concepts to both technical and non-technical stakeholders. You will work closely with your team to share knowledge, review code, and contribute to our engineering culture.

- API and Tool Design: Experience designing, building, and consuming RESTful APIs and other web services.
- Infrastructure and DevOps: Familiarity with modern infrastructure and deployment tools, including Docker, Kubernetes, and CI/CD pipelines.
- Observability: Experience with logging, metrics, and tracing frameworks (e.g., Prometheus, Grafana, OpenTelemetry).
- Communication and Collaboration: Excellent written and verbal communication skills, with the ability to work effectively in a collaborative team environment.
Preferred Qualifications
- Bachelor's degree in Computer Science
- Multi-Agent Systems: Experience designing or building systems where multiple agents collaborate to solve a problem.
- Advanced RAG Pipelines: Experience building and optimizing complex RAG systems, including techniques like re-ranking, query transformation, and graph-based retrieval.
- Prompt Engineering and Fine-Tuning: Expertise in advanced prompt engineering and experience fine-tuning smaller, specialized language models for specific tasks.
- Production Experience: A track record of shipping and scaling agent-based features or products to a large user base.
