AI Lead Architect

Role overview

AI Lead Architect at Dentsu Aegis

Solution Engineering & Technical Execution:

Responsibilities

• o Lead the hands-on engineering for end-to-end AI solutions across Deep Learning,
• GenAI, Agentic AI, and multimodal use cases.
• o Apply rigorous "fail fast" logic to all AI project management.
• Quickly identify,
• evaluate, and disqualify unviable AI use cases based on technical feasibility, effort,
• cost, and risk early in the cycle.
• o Perform explicit trade-off analysis on model class (frontier vs.
• SLM vs. fine-tuned),
• retrieval design, memory optimization, and orchestration.
• o Lead solutioning, support architecture for end-to-end AI solutions across GenAI,
• Agentic AI, multimodal, and applied ML use cases, with explicit trade-off analysis
• on model class (frontier vs.
• SLM vs. fine-tuned), retrieval design, memory, and
• orchestration.
• o Own the practice's reference architectures and solution design patterns for
• multimodal agentic systems, including planning, tool use, memory, grounding, and
• inter-agent communication (MCP, A2A).
• o Conduct solution design reviews across concurrent client engagements; facilitate
• subjective technical decisions and enable delivery excellence.
• Multimodal Agentic Systems & SLM Design:
• o Design and lead the build of multi-agent systems with reasoning, planning, tool
• use, persistent memory, and grounded retrieval.
• o Lead multimodal system design and solutions across text, vision, speech, and
• structured data, including ingestion, representation, and downstream agent
• reasoning.
• o Establish patterns for SLM design and adoption — distillation, fine-tuning,
• quantization, and routing — to meet enterprise constraints on cost, latency, data
• residency, and on-prem/edge deployment
• o Define hybrid retrieval and knowledge architectures spanning vector, graph (KG),
• and NoSQL stores; lead KG-assisted retrieval, entity linking, and structured
• grounding.
• Eval, Guardrails & Production Quality:
• o Establish evaluation as a first-class discipline: design eval frameworks, golden
• datasets, regression suites, automated and human-in-the-loop evals, and
• observability for agentic and generative systems.
• o Define and enforce safety, guardrail, and hallucination-control standards across
• the practice; lead red-teaming and adversarial testing for high-stakes
• deployments.
• o Set the bar for production readiness—reliability, latency, cost, monitoring, drift
• detection, and incident response—for AI systems in regulated, enterprise-grade
• environments.
• o Lead GPU/accelerator ops, model serving, and lifecycle automation for
• deployment across cloud hyper-scalers, on-prem, and edge.
• Technical Leadership & Capability Pillars:
• o Act as a technical sentinel for the AI practice, mentoring engineers through
• rigorous code and architecture reviews to ensure permanent capability building
• rather than temporary crisis management.
• o Establish and enforce AI in SDLC frameworks on delivery projects.
• Cross-functional Leadership & Delivery
• o Engage with client and stakeholder leadership on architecture, feasibility, and risk;
• communicate technical direction clearly to non-technical audiences.
• o Support pre-sales and solutioning for new GenAI and Agentic AI opportunities,
• including effort estimation, architectural framing, and capability storytelling.
