Job Details

Principal AI Architect

Location: Silicon Valley (Onsite) |

Experience: 5+ years |

Visa Sponsorship: No

NO H1B SPONCER/TRANSFER

What you'll do

• Define and own the architectural vision for next-generation AI systems: novel agent

architectures, reasoning systems, and proprietary model development.

• Prototype and evaluate breakthrough AI capabilities — predictive modeling, autonomous

signal synthesis, multi-modal intelligence — that create defensible IP.

• Set the technical foundations: data architecture, model serving, agent orchestration, and

inference infrastructure for a multi-year product horizon.

• Evaluate and adopt emerging AI paradigms (multi-agent reasoning, RLHF, retrievalaugmented

fine-tuning) before they are mainstream.

• Establish engineering standards, architecture review processes, and IP documentation

practices for the team.

What we require

• BS/MS/PhD in Computer Science, AI/ML, or related field. PhD or equivalent research

depth preferred.

5+ years in AI/ML engineering with at least 2 years in a principal engineer or lead

architect role.

• Demonstrated history of building original AI systems that became products — not

implementations of existing patterns.

• Deep expertise across: LLM training and fine-tuning, agentic system design, knowledge

graph construction, large-scale data modeling.

• Comfort operating in greenfield conditions: high ambiguity, high ownership.

• Patents, published research, or shipped products with clear proprietary differentiation are

strong signals.

No visa sponsorship. Must be authorized to work in the US without current or future

employer sponsorship.
