Strong signals include backgrounds from OpenAI, Anthropic, DeepMind, xAI, Meta FAIR, founding engineer roles at high-growth AI startups, and senior engineers at AI-native startups with production agent systems, multi-agent orchestration, AI infrastructure ownership, distributed systems expertise, and personally architected systems deployed to production. Ideal roles: Founding Engineer, Staff Engineer, Principal Engineer, AI Infrastructure Engineer, ML Platform Engineer, CTO, Technical Founder, Applied AI Engineer, Distributed Systems Engineer, or Agent Systems Architect.
