• Implement data pipelines for ingestion, transformation, indexing, and retrieval, including vector stores.
• Create intuitive front-end experiences for AI features like chatbots, copilots, workflows, and dashboards.
• Establish MLOps/LLMOps practices: CI/CD, model/version management, monitoring, and drift detection.
• Define and execute testing strategies: unit, integration, offline evaluations, security red-teaming, and performance testing.
• Optimize AI applications for latency, cost-efficiency, and reliability through caching, batching, and observability.

• DevOps expertise including CI/CD pipelines, infrastructure-as-code (Terraform), and monitoring tools (e.g., OpenTelemetry).
• Strong understanding of secure coding principles and OWASP standards.

It is a strong plus if you have:
