Meet the Team
At Foundation AI, we are leading frontier AI research across Cisco. Our mission is to advance the state of artificial intelligence through fundamental research and translate scientific breakthroughs into differentiated technologies that power the next generation of enterprise AI.
Our research spans foundation models, agentic AI, multimodal learning, reasoning systems, scalable training algorithms, evaluation science, inference optimization, and AI systems infrastructure. We work at the intersection of cutting-edge research and real-world impact, developing technologies that influence Cisco's AI strategy while contributing meaningfully to the broader AI research community.
We believe impactful research should advance both science and products. Our researchers publish at top AI conferences, contribute to open-source projects, collaborate with leading academic institutions, and build production systems that solve challenging enterprise-scale problems.
Your Impact
As a Senior AI Researcher you will operate as a visionary technical leader, architecting and executing frontier AI research that dictates Foundation AI's long-term technical trajectory.
You will identify emerging research opportunities, formulate original research hypotheses, and lead ambitious research programs spanning foundation models, agentic AI, reasoning, multimodal learning, and large-scale AI systems. Working closely with engineering and product team members, you will translate scientific advances into scalable technologies that differentiate Cisco's AI platform.
Working at the highest technical levels, you will translate scientific advances into scalable paradigms that fundamentally differentiate Cisco's AI platform. Beyond individual technical contributions, you will provide scientific leadership across multiple research initiatives, mentor junior researchers and interns, and influence executive technical strategy. You will represent Cisco externally through top-tier publications, open-source leadership, and active collaboration with the global AI research community.
In this role, you will

• Define and direct multi-year research programs aligned with Foundation AI's strategic priorities, setting the technical bar and research methodology for the wider team.
• Invent and pioneer novel architectures and algorithms for foundation model training and inference, complex reasoning agentic AI systems, and multimodal learning.
• Drive frontier research in advanced domains such as reinforcement learning, mechanistic interpretability, and scaling laws, with applications to the cybersecurity domain.
• Design and build new evaluation benchmarks and frameworks that improve the reliability, transparency and safety of AI models.
• Collaborate across research, engineering, product, and security teams to translate research into production AI systems and drive the adoption of the new research across Cisco's AI portfolio.
• Mentor researchers, engineers and interns, elevating the team's scientific rigor and engineering excellence through code reviews, paper reviews, and architectural guidance.
• Publish research in top AI conferences and journals, contribute to open-source AI projects, and represent Cisco through invited talks and technical collaborations.

Minimum Qualifications

• PhD in Computer Science, Artificial Intelligence, Machine Learning, or a related technical field, plus 5+ years of relevant research experience, or equivalent demonstrated research impact.
• Demonstrated track record of sustained, high-impact publications at top-tier machine learning and AI conferences (e.g., NeurIPS, ICML, ICLR, ACL, EMNLP, CVPR, ICCV, or equivalent venues).
• Deep expertise in foundation models, post-training and alignment, LLMs, agentic AI, reinforcement learning, reasoning, efficient inference, or distributed training systems.
• Expert-level proficiency in Python, PyTorch, distributed machine learning, and modern AI research frameworks.
• Proven ability to lead complex, ambiguous technical projects from conception to deployment as an individual contributor.
• Exceptional ability to communicate complex scientific concepts to both highly technical peers and non-technical executive stakeholders.

Preferred Qualifications

• Hands-on expertise in high-performance computing environments, with a track record of leading distributed training across thousands of GPUs using frameworks and communication primitives such as CUDA, NCCL, FSDP2, and Megatron-LM.
• Experience deploying high-performance inference engines such as vLLM and SGLang, and working with cloud-native deployment, Docker, Kubernetes, MLOps pipelines, and major cloud platforms such as AWS, GCP, or Azure.
• Experience designing and scaling agentic AI workflows, multi-agent frameworks, and autonomous AI systems.
• Familiarity with cybersecurity principles, AI systems for security-focused use cases, safety, and robust machine learning.
• Demonstrated leadership within the global AI research community, specifically serving as an Area Chair or senior program committee member for top-tier AI conferences.
