The Principal GenAI & Agentic AI Engineer is the technical leader responsible for designing, building, and scaling AI systems that combine LLM-powered GenAI and ADK-based agentic workflows on Google Cloud Platform. This role also requires leading and developing data pipelines for necessary data layer for AI/ML. This role sets architecture standards, leads multi-team delivery, and governs safety, reliability, and cost at enterprise scale—accelerating product teams to achieve monetization of AI based products through reusable patterns, platforms, and guardrails.
Establish domain and platform standards: model selection, RAG/generation patterns, memory architectures, security baselines, observability, and LLMOps .
Lead portfolio-wide technical decisions (build/buy, vendor selection, SLAs, quotas) with a focus on reliability, safety, and cost control.
Solution Design & Delivery
Architect and lead implementation of production-grade GenAI solutions (Vertex AI models, Grounding, Pipelines, Evaluation) and agentic services (planning, tools, memory, HIL).
Drive end-to-end delivery across teams: data ingestion (Dataflow/Composer), indexing ( BigQuery vectors/Vertex Vector Search), services (Cloud Run/Workflows), events (Pub/Sub).
Build and maintain prompt libraries, tool catalogs , agent templates, and evaluation harnesses for organization-wide reuse.
Standardize LLMOps : CI/CD for prompts/models/agents, model registry, traceability, rollback, canaries, cost/performance scorecards.
Responsible AI, Security & Compliance
Implement multi-layer guardrails: policy prompts, filters, memory governance, tool whitelisting, audit logs; ensure regulator-ready posture.
Codify privacy, PII handling, data residency, and per-tenant isolation using VPC-SC, Secret Manager, IAM, and Apigee policies.
Partner with Product, Security, and SRE to align roadmaps, SLOs, and operational playbooks.
Required Technical Competencies
LLM & GenAI: Model selection (Gemini & Model Garden), prompt engineering, RAG/grounding, multimodal pipelines, fine-tuning/adapter methods.
Agentic AI (ADK): Agent loops, planners, tool/function design, memory (episodic/semantic/long-term), HIL, policy enforcement.
Data & Retrieval: BigQuery (including vector functions), Vertex Vector Search, Document AI, Dataplex for lineage and governance.
Orchestration & Services: Cloud Run, Workflows, Pub/Sub, Dataflow/Composer; HA/DR, backpressure, circuit breakers.
LLMOps / MLOps : Vertex AI Pipelines, registry, CI/CD, trace correlation, cost/performance monitoring.
Security & Compliance: IAM, Secret Manager, VPC-SC, private service connect, DLP, Okta/IAP, Apigee API policies.
Observability & Cost: Central telemetry, user feedback loops, drift/outlier detection, quota/capacity planning.
Proven delivery of enterprise-scale GenAI/agent platforms on GCP (Vertex AI, BigQuery , Cloud Run, Pub/Sub, Workflows).
