Responsibilities

• Agent Architectures: Design and build complex agent workflows using frameworks like LangGraph/LangChain, leveraging MCP, RAG/GraphRAG, and custom skill integration.
• Generative Content Pipelines: Architect Gen2D/Gen3D/video generation workflows (Stable Diffusion, Open Source LLMs) that integrate seamlessly with DCC tools and game engines.
• Production Engineering: Move beyond notebooks. Build robust evaluation frameworks and deploy efficient, cost-effective systems using Python, FastAPI, AWS (SageMaker/Bedrock), and MLOps best practices.
• Technical Scoping: Navigate ambiguous problems by building PoCs to validate feasibility. Collaborate with product and creative teams to translate technical constraints into realistic roadmaps.

Qualifications

• Experience: 7+ years building production systems (ML/AI focus), with a proven track record of shipping code — or demonstrably equivalent transferable experience. • Technical Depth: Demonstrable expertise in Agent Architectures or Generative Content workflows (or both). • Comfort with Ambiguity: You don't wait for a spec sheet. You enjoy exploring a blank canvas, building a prototype, and iterating until the path forward is clear. • Pragmatism: Ability to determine when to use off-the-shelf models vs. fine-tuning vs. simple scripts. • Stack Familiarity: Strong proficiency in Python, with experience in AWS, LangChain/LangGraph, ComfyUI, or similar modern AI stacks.
