Job Summary: The Principal Engineer operates at the intersection of deep technical execution and broad organizational influence.
This role will resolve the hardest architectural questions, set the AI-native engineering bar, and ensure that iHerb's platform decisions compound over time rather than accumulate debt.
Reporting to the VP of Engineering this role collaborates closely with peer Principals, Engineering Managers, and peer VPs across the organization.
This role owns the end-to-end technical strategy for iHerb's AI Platform and GenAI product experiences.
This spans the user-facing AI layer (Wellness Agent, LLM-driven recommendations, RAG over catalog and reviews, generative content) and the shared AI infrastructure (RAG pipelines, evals framework, MLOps, guardrails, observability) that makes AI features production-grade and repeatable across the engineering organization.
Job Expectations: Define and own the AI platform architecture: retrieval infrastructure, model lifecycle, evals framework, guardrails, and GenAI product feature design.
Hands-on contributor: build production AI systems, write proofs of concept, and validate architecture through working software.
Set and enforce technical standards for the AI Platform team; drive architecture reviews and model quality reviews.
Coordinate with the Personalization team to define clear boundaries between the GenAI product layer and existing ML personalization infrastructure.
Contribute AI platform-specific patterns and lessons into iHerb's shared AI-driven SDLC golden path.
Drive the hardest cross-cutting technical decisions across multiple teams and shared platform services.
Establish and evolve iHerb's AI-driven SDLC golden path: shared standards, Claude Code.
