Principal Solutions Architect – AI/ML
About the role
The Strategic Accounts SSA team partners with AWS's most advanced customers to design and deploy multi-agent AI systems on Amazon Bedrock, SageMaker, and Amazon Q. As a Principal Solutions Architect specializing in agentic AI, you'll architect autonomous agent ecosystems — supervisor and broker patterns, multi-agent collaboration frameworks, and tool-using agents that plan, reason, and act across enterprise workflows with minimal human oversight.
This is a technical leadership role: you'll work directly with product teams to shape the agentic AI roadmap, build reference architectures and POCs that customers deploy in production, and set the technical bar for how AWS's broader SA community approaches agentic systems.
What you'll do
Architect multi-agent systems for enterprise customers — memory, retrieval-augmented generation, planning/reasoning loops, and tool orchestration — using Bedrock, SageMaker, and Amazon Q
Design and guide custom model training efforts, including fine-tuning foundation and open-source models (e.g., BERT,



Llama family) for domain-specific agent tasks
Define and implement the model SDLC for customer engagements — data preparation, training/fine-tuning, evaluation, versioning, deployment, and monitoring/retraining loops
Establish and roll out model best-practice frameworks (evaluation rubrics, guardrails, responsible AI checks, cost/performance benchmarks) that customers and internal teams adopt as standard
Build and present proof-of-concepts and reference architectures that demonstrate measurable business impact from autonomous agent workflows
Evaluate agent reasoning performance (accuracy, cost, latency, failure modes) and translate findings into design recommendations
Partner with AWS product and service teams, feeding customer requirements into the Bedrock/agentic AI roadmap
Advise customers and internal stakeholders — from engineers to C-level executives — on agentic AI strategy, transla
