Artificial Intelligence Specialist

Architecture & Solution Design

• Define reference architectures for GenAI systems: RAG, agentic orchestration, tool/function calling, multi-step reasoning workflows, memory patterns, and context strategies.
• Design multi-tenant and enterprise-scale GenAI platforms with clear separation of concerns: UI, orchestration, retrieval, inference, evaluation, and observability.
• Select model strategies: hosted LLMs, open-weight models, fine-tuning vs. prompt/RAG, latency and cost tradeoffs, and deployment patterns.

2) Agentic AI Orchestration & Tooling

• Architect agent systems (single/multi-agent) including:
• Task decomposition, planners/executors, reflection/verification loops
• Tool use patterns (APIs, databases, search, workflow engines)
• Guardrails to prevent unsafe tool actions and hallucinated commands
• Build reliable flows for “human-in-the-loop” decision points and approvals (e.g., procurement, customer comms, incident triage).

3) Retrieval, Knowledge Systems & Data Design

• Lead design of knowledge ingestion pipelines:
• document parsing, chunking strategies, embeddings, metadata, lineage, freshness SLAs
• Architect vector search and hybrid retrieval:
• semantic + keyword, reranking, filtering, ACL-aware retrieval
• Ensure retrieval respects access control, PII handling, data residency, and auditability.

4) Production Engineering, Reliability & Cost

• Set non-functional requirements for GenAI workloads:
• SLOs, latency budgets, fallback models, caching, rate limiting
• Design cost controls: prompt/token optimization, model routing, batching, and usage governance.
• Implement resiliency patterns: circuit breakers, retries, queue-based orchestration, idempotency.

5) Security, Risk & Responsible AI

• Establish AI security posture:
• prompt injection defenses, data exfiltration controls, tool sandboxing
• Define policies and controls for:
• sensitive data, logging, redaction, encryption, secret management, and auditing
• Collaborate with risk/compliance to drive:
• model governance, content safety, bias/quality monitoring, and regulatory alignment

6) Evaluation, Observability & Continuous Improvement

• Create evaluation frameworks:
• offline evals (golden sets), automated regression, and scenario-based testing
• Instrument systems for observability:
• traces, prompt/versioning, retrieval diagnostics, tool-call logs, and outcome metrics
• Run A/B tests and iterate on prompts, retrieval, and agent policies based on measurable outcomes.

7) Leadership & Stakeholder Management

• Partner with product leaders to identify high-value use cases and define roadmap.
• Mentor engineers and data scientists on best practices for LLM apps.
• Produce architecture artifacts: ADRs, threat models, system diagrams, runbooks.
