Principal AI/ML Architect

• Set enterprise AI architecture and technical direction: Own the end-to-end architecture for complex GenAI, agentic AI, and ML platforms. Define reference architectures, reusable patterns, engineering guardrails, and technology choices across engagements.
• Build at the frontier - hands-on: Stay close to the code on the highest-leverage technical work, including foundation-model and embedding fine-tuning, advanced RAG, semantic search, evaluation harnesses, and novel agentic workflows using Python and Google Cloud Vertex AI.
• Engineer AI for production: Design for latency, reliability, security, cost, scalability, and maintainability from day one. Apply disciplined MLOps and LLMOps practices so systems are versioned, evaluated, monitored, deployed, and continuously improved.
• Architect agentic systems at scale: Design and operate multi-step reasoning and multi-agent workflows using ADK, LangChain, MCP, and custom agent frameworks, with robust orchestration, state management, tool use, memory, human oversight, failure isolation, and verification controls.
• Establish evaluation, observability, and responsible AI standards: Define measurable quality criteria and production telemetry for accuracy, groundedness, safety, drift, latency, and cost. Embed privacy, security, governance, and responsible AI throughout the lifecycle.
• Shape data and retrieval architectures: Design production-scale retrieval and knowledge systems spanning data ingestion, chunking, metadata, embeddings, vector and hybrid search, re-ranking, provenance, permissions, and continuous content refresh.
• Advise clients and shape opportunities: Partner with client executives and engineering leaders to translate business strategy into AI roadmaps and solution architectures. Lead discovery, technical workshops, estimates, trade-off discussions, and pre-sales solutioning.
• Multiply engineering capability: Raise the technical bar through architecture reviews, design documents, code reviews, mentoring, reusable accelerators, and clear standards that help senior and mid-level engineers deliver with greater confidence.
• Own outcomes across the full lifecycle: Guide initiatives from problem framing and experimentation through production rollout, operational readiness, adoption, and measurable business value. Surface risks early and drive decisions to resolution.
