Meet the Team

The AI Platforms and Enablement team is the engine behind Cisco's internal AI transformation. Our mission is to build and scale CIRCUIT, Cisco's universal enterprise AI platform designed to collapse information silos and amplify productivity through intelligent, agentic experiences. As a team of researchers, engineers, and AI practitioners, we bridge the gap between powerful industry innovation and practical, production-grade applications.

We provide the foundation for Cisco to reimagine work through secure, scalable AI, enabling business units to integrate proprietary data and transform legacy workflows into intelligent, autonomous systems. We value technical depth, rapid prototyping, applied research, production engineering field, and solving complex architectural challenges across models, agents, harnesses, inference efficiency, and enterprise AI governance.

Your Impact

• You will direct, mentor, and work alongside a specialized team of AI practitioners. You will contribute to architecture, code reviews, model evaluations, prototype implementations, and technical design decisions to ensure high-quality outcomes.

• You will define Cisco-scale agentic system architecture, including planning, tool execution, agent-to-agent handoffs, memory, persistent state, human approval, policy enforcement, secure tool access, observability, and failure recovery.

• You will build rigorous evaluation harnesses for models, prompts, RAG systems, tools, agents, and multi-agent workflows. You will establish offline and online metrics for task success, tool-call accuracy, groundedness, hallucination rate, safety, latency, and cost.

• You will own the strategy for frontier models, open-weight LLMs, SLMs, fine-tuned domain models, distilled models, and model routers. You will define when Cisco should use vendor-hosted models, self-hosted models, fine-tuned models, or task-specific small models.

• You will continuously benchmark emerging LLMs, SLMs, and Agent Harnesses. You will lead fine-tuning of open-weight models to meet Cisco's security, domain, latency, cost, and quality requirements.

• You will drive model-serving efficiency through routing, batching, caching, quantization, distillation, context optimization, structured outputs, and serving-stack improvements. You will own cost-quality-latency tradeoffs across production AI workloads.

• You will track breakthroughs in AI research and translate them into production-grade capabilities, reusable platform primitives, and validated improvements to CIRCUIT.

• You will establish technical standards for secure, observable, auditable, policy-compliant AI agents operating over Cisco enterprise data and systems.

• You will accelerate internal AI development through better tooling, reusable agent patterns, evaluation frameworks, deployment pipelines, and AI-assisted engineering workflows.

• You will operate at the highest levels of Cisco’s internal AI infrastructure, managing significant platform scale, high-volume inference, and complex enterprise requirements.

• You will own the optimization of a substantial annual model spend portfolio, drive critical reliability targets (p95/p99 latency, groundedness), and lead a multidisciplinary team of researchers and engineers. You will set the technical AI strategy in partnership with VP/SVP-level leadership across engineering, product, and security.

• You will be measured on your ability to drive tangible improvements in AI productivity (hours saved, workflow cycle-time reduction), agent reliability (task completion rates, reduction in human overrides), model quality (groundedness, hallucination reduction), inference economics (cost per successful task, GPU utilization), and developer velocity (time-to-production, evaluation coverage).

Minimum Qualifications

• Bachelor's degree in Computer Science, Engineering, AI/ML, or a related field, or equivalent practical experience.

• 15+ years or a PhD with 10+ years of combined experience in software engineering, systems architecture, machine learning, AI platforms or distributed systems.

• Experience architecting or operating production LLM, agentic AI, model-serving, or applied AI systems at enterprise scale.

• Demonstrated ability to build or lead evaluation systems for LLMs, RAG pipelines, tools, autonomous agents, or model-powered enterprise workflows.

• Experience with model efficiency techniques such as model routing, caching, quantization, distillation, prompt/context optimization, batching, or high-throughput inference serving or similar work.

• Deep expertise in AI/ML systems, model deployment, distributed platform design, applied AI architecture, and production software engineering practices.

• Prior experience driving platform strategy and technical innovation at enterprise scale.

• Demonstrated experience influencing product, engineering, security, infrastructure, and leadership organizations through technical strategy, architecture reviews, prototypes, and measurable platform outcomes.

Preferred Qualifications

• Advanced degree or equivalent experience (Master's or PhD) in Computer Science, AI/ML, Systems Engineering, or a related field.

• Demonstrated excellence in a Principal Engineer, Distinguished Engineer, Director, or equivalent senior technical leadership role within AI/ML, distributed systems, or enterprise platforms.

• Deep expertise in enterprise AI platforms, LLMs, SLMs, agentic systems, and model-serving architectures (e.g., vLLM, TensorRT-LLM, Ray, Kubernetes-based GPU platforms).

• Proficiency in the full AI lifecycle, including model training, fine-tuning (LoRA/QLoRA), routing, compression, quantization, and inference optimization.

• Extensive experience with agent runtimes, orchestration, tool-calling, human-in-the-loop workflows, m
