About the Team
The TikTok U.S. Data Security (USDS) team is responsible for the security, integrity, and compliance of TikTok’s data within the United States. The Data Platform Team builds a scalable, reliable, cost-efficient infrastructure that ensures data integrity and empowers every business unit to win through self-service tools and scientific insights.
About the Role
We are seeking a Senior Machine Learning Engineer to join our team as a technical lead, driving the architecture and execution of our next-generation AI Risk & Compliance Intelligence Platform and Intelligent Data Agent Ecosystem. In this role, you will be instrumental in bridging the gap between standard prompt engineering and native, model-driven reasoning frameworks. You will tackle complex ML challenges around offline/online evaluation, synthetic data generation for small-sample scenarios, and automated agent skill optimizations across Data & Engineering workflows (DA/DS/DE/SRE).
Key Responsibilities
- Design, build, and scale robust LLM evaluation architecture, including automated offline datasets, metric suites, and benchmarking pipelines to measure prompt and model performance.
- Innovate on LLM-driven synthetic data generation methodologies to tackle data scarcity bottlenecks and systematically evaluate long-tail/edge-case risk scenarios.
- Advance beyond criteria-based prompt engineering by extracting deep risk patterns directly from complex case data to build native, ML-driven decision models and reasoning abstractions.
- Architect, evaluate, and continuously optimize modular agent skills and tools tailored for Data Science, Analytics, Data Engineering, and SRE workflows to maximize tool-use accuracy, execution efficiency, and task success rates.
- Implement advanced evaluation methodologies (such as LLM-as-a-judge and multi-agent benchmarking) across both risk intelligence and agentic ecosystems.
- Provide technical leadership by establishing core ML system design patterns, benchmarking standards, and engineering best practices, while translating complex operational requirements into scalable machine learning solutions across cross-functional partnerships.
Qualifications
Minimum Qualifications
- Experience: 5+ years of software/ML engineering experience with a strong track record of designing, building, and deploying ML/LLM systems in production.
- Generative AI & LLMs: Deep hands-on expertise with LLM architectures, fine-tuning, RAG, prompt tuning, and agentic frameworks.
- Evaluation & Data Bootstrapping: Demonstrated experience building robust LLM evaluation frameworks (LLM-as-a-judge, automated benchmark pipelines) and tackling data scarcity/imbalance problems.
- Core Engineering: Strong coding skills alongside production experience with scalable data processing pipelines.
Preferred Qualifications
- Prior domain experience in Risk & Compliance Intelligence and Automated Decision Systems.
- Hands-on experience with synthetic dataset generation or bootstrapping models for cold-start scenarios.
- Experience building AI tools or agents for technical personas (Data Analysts, Data Scientists, Data Engineers, Data SRE).
- Demonstrated ability to serve as a founding technical lead on ambiguous, high-impact initiative pods.

Machine Learning Intern Jobs in San Jose: Frequently Asked Questions
How do I get a machine learning intern job in San Jose?
The strongest path into a machine learning intern role in San Jose runs through the city's semiconductor and enterprise software clusters in North San Jose and the Alviso corridor. Employers in these sectors prioritize candidates with hands-on Python or PyTorch experience and at least one completed ML project. Targeting mid-size AI infrastructure firms alongside the larger tech employers gives you a real edge, since competition for marquee-name internships is intense.
Which companies hire machine learning interns in San Jose?
San Jose machine learning intern roles are posted by TikTok, ByteDance, and TikTok USDS JV and others right now, based on current listings on Migrate Mate as of November 2026. San Jose's employer base skews heavily toward semiconductor companies, enterprise cloud platforms, and AI-focused hardware firms, making it one of the denser local markets for applied ML internship work.
Are there remote machine learning intern jobs in San Jose?
Yes, though availability depends on the work. Machine learning intern roles tied to hardware validation or lab access are almost always on-site, while data pipeline, model training, and analytics-focused positions are more likely to offer flexibility. About 25% of machine learning intern openings tied to San Jose are remote or hybrid as of November 2026, with hybrid arrangements most common at enterprise software employers in the Downtown and North San Jose corridors.
How can I get a machine learning intern job in San Jose with little or no experience?
The most realistic entry path in San Jose is through research internships at institutions like San Jose State University or through junior data analyst roles at mid-size enterprise software firms that funnel strong performers into ML tracks. Building a public portfolio of completed projects on GitHub and targeting smaller AI startups in North San Jose, where teams move faster and rely more on generalist contributors, gives candidates without formal work history a concrete foothold.
Which industries hire the most machine learning interns in San Jose?
The sectors hiring the most machine learning interns in San Jose are Technology & Software, Fintech, and Social Media, based on current listings on Migrate Mate as of November 2026. San Jose's position as a center for semiconductor design and enterprise cloud infrastructure means local ML intern demand is driven heavily by applied research and product development work rather than purely analytical roles.
