Job Description

They are looking for a Sr. Software AI Engineer who will write production code, own features end-to-end from spec through deployment, operations, and observability, and participate in on-call rotation for what the team ships. There is no handoff to a separate ops or reliability function; engineers own the full lifecycle. Test automation is built into the shipping process using AI-driven tooling and the golden path.

Build the GenAI-powered product experiences and the shared AI platform infrastructure that powers them. This includes RAG pipelines over the catalog and customer reviews, LLM-driven personalization, a conversational Wellness Agent, agentic workflow systems, and the evals and MLOps layer that makes AI features production-grade and repeatable. Specializations within this track include: RAG and personalization, agent framework and tool use, evals and guardrails, and LLM application development for internal business functions such as marketing automation and BI agents.

What you will do:

- Design, build, and operate production AI features: RAG pipelines, LLM-driven recommendations,



conversational agents, or agentic workflow automation.
- Build the shared AI platform layer: retrieval infrastructure, eval frameworks, model monitoring, guardrails, and observability.
- Write LLM applications and integrations with marketing platforms, BI tools, or customer-facing product surfaces.
- Evaluate model and feature quality using structured eval frameworks; iterate on prompts, retrieval strategies, and model selection using data.
- Use AI-driven SDLC tooling such as Claude Code as a daily practice for both AI and non-AI code.
- Coordinate with the Personalization team to align GenAI product features with existing ML personalization signals.
- Document AI system design decisions, evaluation results, and operational lessons in the shared knowledge base.
- Own the observability of AI systems you build: latency, cost, quality drift, and error rates; participate in on-call rotation and respond to production incidents.
