• Ability to influence product direction and communicate architectural trade-offs to engineers and executives.
• Gaming, payments, or e-commerce background is a plus.
• Fine-tuning, multi-agent orchestration, LLM evaluation, and AI compliance experience are pluses.

Responsibilities

• Design end-to-end agentic architectures including tool-use schemas, intent parsing, multi-step orchestration, and safety guardrails.
• Define multi-modal interface strategy across UI, API, SDK, and agentic natural language.
• Design a horizontal LLM platform layer with shared RAG pipelines, prompt libraries, vector search infrastructure, and evaluation frameworks.
• Prototype AI product hypotheses before full engineering investment.
• Ensure systems include observability, documentation, and engineering runbooks.
• Shape AI product strategy and prioritization with Product leadership.
• Select and govern LLM providers and deployment strategies.
