Data Engineer III

Data Analytics & Engineering - Data Engineer III Generative AI models are only as good as the data they consume. Unlike traditional data engineering, building data pipelines for generative AI requires orchestrating ML model invocations (content understanding classifiers, embedding models, LLM-based cleaners) alongside standard SQL-based transformations, all at billion-row scale. Start/End Dates: 7/13/2026 - 12/31/2026 Tax Work Location: US - CA - Menlo Park (105201) Job Responsibilities AI-Augmented Data Pipelines: Design and maintain AI-augmented, large-scale data pipelines (billions of images) integrating traditional transformations with ML models (classifiers, embeddings, LLMs) for cleaning and annotation. Remote Inference Orchestration: Own the systems for remote ML model inference orchestration within pipelines, managing batching, retries, async jobs, and ensuring graceful degradation. Feature Pipelines: Build and maintain scalable pipelines for generating, storing, and serving vector embeddings, including nearest-neighbor index management and quality validation. Data Curation at Scale: Source, filter, and curate training datasets using a combination of SQL and model-derived signals (e.g., aesthetic scores, NSFW classifiers), owning the end-to-end data flow and maintaining governance, quality, and compliance. Additional Responsibilities LLM-Assisted Annotation: Design and operate pipelines that use LLMs and vision models for automated annotation of training data, including auditing workflows to measure and improve annotation model performance. Tooling & Frameworks: Contribute to shared tooling and frameworks that make it easier for the broader team to build AI-augmented data pipelines – e.g., reusable operators for model invocation, standard patterns for async job management. Skills Required Advanced SQL & data pipeline expertise. Complex queries, query optimization, pipeline orchestration frameworks (Airflow, Dataswarm, or equivalent). Experience integrating ML models into data pipelines – calling inference endpoints, managing model versions, batching requests, handling inference failures at scale. Proficiency with AI-assisted coding agents (e.g., Copilot, Cursor, Codex). Expected to leverage AI tools as a force multiplier for writing, debugging, and reviewing code, building pipelines faster, and accelerating day-to-day engineering workflows. Strong verbal and written communication skills, problem-solving ability, and cross-functional collaboration. Preferred Working knowledge of embeddings and vector representations – generating, storing, indexing, and querying embeddings (FAISS, Milvus, or equivalent). Familiarity with content-understanding models like image classifiers, object detection, OCR, NSFW detection, aesthetic scoring. Experience with LLMs for data tasks such as prompt engineering for annotation, data cleaning, or evaluation using LLM APIs. Knowledge of generative AI like diffusion models, image generation, evaluation metrics (FID, CLIP score, etc.). Education / Experience Bachelor's degree or higher in Computer Science, Data Engineering, Machine Learning, or a related STEM field. 5+ years of industry experience in data engineering, ML engineering, or a hybrid role involving both data pipelines and model serving/inference. Demonstrated track record of building and operating production data pipelines that invoke ML models at scale. #J-18808-Ljbffr
