The role introduces new architectural approaches, evaluates emerging technologies, and shapes the long-term roadmap for the firm’s AI ecosystem. Primary Responsibilities Define and maintain the enterprise‑grade AI platform architecture, including orchestration layers, LLM integration patterns, vector/RAG pipelines, agent frameworks, API mesh, and reusable shared services. Develop architectural standards, guardrails, and reference designs governing how engineering teams build and integrate AI workloads. Translate business and product requirements into detailed technical designs, ensuring scalability, security, reliability, and alignment with enterprise architecture principles. Evaluate build‑vs‑buy decisions for AI components, frameworks, and cloud services; develop recommendations and influence cross‑functional stakeholders. Review solution designs from engineering teams; identify risks, surface architectural gaps, and recommend long‑term, sustainable approaches. Partner with Security, Compliance, Legal, and Risk to embed SOX, SOC 2, PCI, PII, data residency, and other regulatory requirements into architectural designs. Collaborate with Data Platform teams to define data access patterns, boundaries, governance expectations, and integration mechanisms aligned with enterprise data strategy. Lead development of architectural decision records (ADRs), integration specifications, and platform documentation supporting engineering and compliance readiness. Assess LLM providers, model hosting patterns (e.g., Bedrock, SageMaker, open-source models), and orchestration frameworks; continuously recommend improvements based on evaluation of emerging capabilities. Drive cross-functional alignment on AI design choices and platform evolution; facilitate architectural reviews, design sessions, and technical deep dives. Provide expert-level guidance and mentorship to engineering teams implementing AI services, pipelines, and production applications. Ensure AI solutions follow cloud best practices across reliability, cost efficiency, observability, performance, and operational readiness. Partner with Product, Engineering, and Enterprise Architecture to influence long-term platform direction, including multi-tenant patterns, internal developer experiences, and future-state AI services. Support readiness for audits and risk assessments by ensuring AI platform design documentation, logs, and controls meet enterprise and regulatory expectations. Champion engineering excellence, standardization, and modernization through clear architectural principles, platform governance, and adoption of best‑in‑class tools and patterns. Required Knowledge, Skills & Abilities Deep technical expertise in AI/ML platform architecture, including LLMs, RAG pipelines, vector databases, agent frameworks, orchestration systems, and prompt/response patterns. Expert-level AWS knowledge (e.g., Bedrock, SageMaker, Lambda, ECS/EKS, API Gateway, IAM, KMS, networking, security controls). Strong understanding of enterprise integration patterns, API design, event-driven architectures, service mesh, and distributed systems engineering. Advanced knowledge of secure design principles, compliance frameworks, and architectural controls for regulated environments (SOX, SOC 2, PCI, PII, data residency). Ability to simplify highly complex concepts, communicate architectural decisions to technical and non-technical stakeholders, and influence senior leadership. Strong analytical and problem‑solving skills, capable of evaluating multiple technical paths and making sound recommendations under ambiguity. Demonstrated ability to drive architectural alignment across cross-functional engineering teams. Proficiency with cloud-native observability, monitoring, scalability desi
