Principal Architect (Artificial Intelligence)

Principal AI ArchitectLocation: Silicon Valley (Onsite) | Experience: 5+ years | Visa Sponsorship: NoNO H1B SPONCER/TRANSFERWhat you'll do• Define and own the architectural vision for next-generation AI systems: novel agentarchitectures, reasoning systems, and proprietary model development.• Prototype and evaluate breakthrough AI capabilities — predictive modeling, autonomoussignal synthesis, multi-modal intelligence — that create defensible IP.• Set the technical foundations: data architecture, model serving, agent orchestration, andinference infrastructure for a multi-year product horizon.• Evaluate and adopt emerging AI paradigms (multi-agent reasoning, RLHF, retrievalaugmentedfine-tuning) before they are mainstream.• Establish engineering standards, architecture review processes, and IP documentationpractices for the team.What we require• BS/MS/PhD in Computer Science, AI/ML, or related field. PhD or equivalent researchdepth preferred.• 5+ years in AI/ML engineering with at least 2 years in a principal engineer or leadarchitect role.• Demonstrated history of building original AI systems that became products — notimplementations of existing patterns.• Deep expertise across: LLM training and fine-tuning, agentic system design, knowledgegraph construction, large-scale data modeling.• Comfort operating in greenfield conditions: high ambiguity, high ownership.• Patents, published research, or shipped products with clear proprietary differentiation arestrong signals.• No visa sponsorship.
