About this role

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.

8+ years of software engineering experience. Fully autonomous; drives technical decisions within the team; mentors junior engineers. Python proficiency; comfortable building and operating production LLM applications. Hands-on experience with at least one specialization: RAG and retrieval systems, LLM evaluation, agentic frameworks (LangChain, LlamaIndex, or similar), or LLM-based workflow automation. Understanding of prompt engineering, context window management, and LLM output quality tradeoffs.
