Job summary

Robotics Technologies LLC is seeking an AI Data Engineer in Phoenix to design, build, and optimize data pipelines powering AI/ML initiatives. You’ll manage ingestion, cleaning, and transformation of structured and unstructured data for model training and deployment.

You will develop vector embedding pipelines, feature stores, and RAG-enabled architectures, ensuring data quality, lineage, and governance across systems.

Qualifications

• Proficiency in SQL and Python/Scala for pipeline development.
• Experience with a cloud data platform.
• Experience with orchestration tools such as Airflow and dbt.
• Understanding of embedding models, vector search, and RAG patterns.
• Experience with unstructured data processing.

Responsibilities

• Design and build pipelines to ingest, clean, and transform structured and unstructured data (documents, PDFs, transcripts, logs) for AI/ML use cases.
• Build and maintain vector embedding pipelines and support vector database integration
• Develop feature stores/pipelines for ML model training and inference
• Implement data pipelines supporting RAG architectures - chunking strategies, embedding refresh cycles, metadata tagging
• Partner with ML engineers'/data scientists to understand data requirements for model training and evaluation
• Ensure data lineage, quality, and governance across pipelines feeding AI systems
• Optimize pipelines for cost and performance (e.g., Dynamic Tables, streaming ingestion)
• Support MLOps/LLMOps workflows - versioning datasets, tracking data used in model training for reproducibility and compliance
• Implement entitlement/access control logic so AI systems only access data they're authorized to use

Job Description

We're looking for a Data Engineer to build and maintain the data infrastructure powering our AI/ML initiatives - including data pipelines for model training, retrieval-augmented generation (RAG), and production ML systems. This role sits at the intersection of data engineering and applied AI, ensuring high-quality, well-governed data is available for both traditional analytics and AI consumption.

Key Responsibilities:

• Design and build pipelines to ingest, clean, and transform structured and unstructured data (documents, PDFs, transcripts, logs) for AI/ML use cases
• Build and maintain vector embedding pipelines and support vector database integration
• Develop feature stores/pipelines for ML model training and inference
• Implement data pipelines supporting RAG architectures - chunking strategies, embedding refresh cycles, metadata tagging
• Partner with ML engineers'/data scientists to understand data requirements for model training and evaluation

• Support MLOps/LLMOps workflows - versioning datasets, tracking data used in model training for reproducibility and compliance
• Implement entitlement/access control logic so AI systems only access data they're authorized to use

Required Skills/Experience:

• Strong SQL + one of Python/Scala for pipeline development
• Experience with a cloud data platform
• Experience with orchestration tools (Airflow, dbt)
• Understanding of embedding models, vector search, and RAG patterns
• Experience with unstructured data processing
