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.

ML Engineer Jobs in Washington: Frequently Asked Questions
How do you become a ml engineer in Washington?
Most ml engineer roles in Washington require a bachelor's degree in computer science, mathematics, or a closely related field, though many employers prefer or require a master's degree for senior positions. Washington has no state-issued license for ml engineers. The most reliable path into the field involves building a portfolio of end-to-end projects, contributing to open-source work, and targeting the associate or new-grad programs that large Washington-based tech employers run each year.
Which companies hire ml engineers in Washington?
Employers hiring ml engineers in Washington right now include TikTok, Meta, and Amazon, based on current listings on Migrate Mate as of November 2026. Washington's density of cloud and enterprise software headquarters means the hiring pool is unusually deep, with both large tech companies and a growing layer of AI-focused startups maintaining consistent demand.
Which Washington cities have the most ml engineer jobs?
Seattle, Bellevue, and Redmond have the most ml engineer openings in Washington. Seattle drives the majority of listings given the headquarters presence of Amazon and the large Microsoft campus nearby in Redmond and Bellevue, while Kirkland has added volume through Google's growing engineering offices and a cluster of AI startups in the greater Eastside corridor.
Are there remote ml engineer jobs in Washington?
Yes, and more than most fields. About 29% of ml engineer openings tied to Washington are remote or hybrid as of November 2026, reflecting how much of the work involves writing, training, and evaluating models rather than on-site operations. Research-oriented and MLOps roles tend to be the most fully remote, while positions requiring close collaboration with hardware or product teams are more likely to require on-site presence.
How can I get hired as a ml engineer in Washington with little or no experience?
The most realistic entry path is a strong project portfolio combined with targeting new-grad or associate ML engineer programs at Washington's large tech employers, where Microsoft, Amazon, and Apple all run structured new-graduate pipelines. Candidates coming from data analyst, data engineer, or software developer roles have a natural on-ramp, since those titles build the Python, SQL, and systems skills that hiring managers look for first. A completed Kaggle competition or a publicly available model deployment carries real weight when experience is limited.
Where can I find and apply to ml engineer jobs in Washington?
You can find and apply to ml engineer jobs in Washington on Migrate Mate, which lists current Washington openings across the state. Find roles that fit your background and apply directly to the ones that match.
