As part of the RDI team, you will:

• Design and implement ETL/ELT pipelines for structured and unstructured data, optimized for embedding generation and vector indexing.
• Build and maintain embedding pipelines using OpenAI, Hugging Face, or Vertex AI models
• Develop and manage vector databases for semantic search and similarity matching.
• Integrate metadata-aware filtering and real-time upserts for contextual and dynamic querying.
• Collaborate with platform teams to ensure secure provisioning, RBAC, encryption, and compliance with data governance policies.
• Optimize performance using GPU acceleration, tiered storage, and ANN indexing algorithms.
• Support observability, monitoring, and incident response for data pipelines and vector infrastructure.
• Contribute to the AIBE Data Hub and RAG-as-a-Service initiatives.

About you:

• Bachelor’s or master’s degree in computer science, Data Engineering, or related field.
• 8+ years of experience in data engineering, with at least 3 years managing unstructured data and embedding pipelines
• Strong proficiency in Python, and data pipeline tools (Dataflow, Pub/Sub, Cloud Functions, Cloud Storage, Apache beam, Air Flow, Vertex AI Pipelines, Kafka, Flink).
• Experience with embedding models and vector search platforms (e.g., BigQuery Vector Search, QDRANT)
• Deep understanding of unstructured data processing, especially text, PDFs, etc.
• Familiarity with cloud platforms (Azure, GCP, AWS) and services like Databricks, Vertex AI, and Dataflow.
• Knowledge of containerization and microservices (Docker, Kubernetes).
• Experience with CI/CD pipelines, Terraform, and DevSecOps practices.

Desirable Experience

• Hands-on experience with hybrid search and agentic workflows.
• Familiarity with multimodal analytics and joining structured/unstructured data for advanced use cases.
• Contributions to platform-level services such as RAG-as-a-Service and embedding generation frameworks.

We appreciate you may not meet all listed criteria above, but if you have the passion and eagerness to learn and grow, we want to hear from you!!
