US Prime and Marketing Tech (UPMT) GeMA team is revolutionizing customer
relationship management through generative marketing agentic workflows (GeMA).
The GeMA’s SDEIII role will lead the cross-organizational initiative to develop
and implement a cohesive Agentic Marketing Framework aligned with agentic
components of GeMA (Customer Understanding, Channel Delivery, Content Creation,
CX, Copy, Creative, and Critic). This role will connect multiple engineering and
science teams to audit, consolidate, and develop AI-based solutions that
transform how Amazon reaches customers with personalized marketing at scale
across Stores.
Technical Leadership and Scope
The SDE III will develop the technical foundation for GeMA's multi-agent
architecture, creating clear interfaces between the agentic components of GeMA
while ensuring system cohesion. The Principal Engineer will be responsible for
designing fault-tolerant multi-agent orchestration patterns, establishing
evaluation frameworks for agent performance, and defining data contracts between
components. The role requires aligning technical vision across numerous
stakeholder teams like P13N (MessageCraft), AME, and NA Stores through detailed
technical specifications and reference implementations.
The SDE III will influence strategic technical decisions by presenting novel
architectures to senior leadership, including SVPs and S-team members,
demonstrating advanced prototypes that balance innovation with practical
implementation paths. Technical artifacts will include architectural decision
records (ADRs) for model selection trade-offs, reference implementations showing
agent-to-agent communication patterns, and technical roadmaps balancing
short-term wins with long-term architectural evolution.
