Meet the Team

Join a collaborative team of researchers and engineers dedicated to unlocking insights from substantial volumes of structured, unstructured, transactional, and real-time data. Together, we analyze diverse data sources to understand customer usage patterns and deliver actionable, impactful insights using advanced metrics, algorithms, and statistical techniques.

Your Impact

As an AI Research Intern, you will contribute to sophisticated research in large language models (LLMs), natural language processing (NLP), and multimodal deep learning. Working with senior researchers and cross-functional teams, you’ll help build, implement, and evaluate machine learning models and algorithms. You’ll participate in data collection, preprocessing, and analysis, and assist in developing and fine-tuning AI models for a variety of applications. Your expertise in data manipulation, model building, and database design will help transform raw data into important insights, while you continue to develop your skills with the latest tools and frameworks.

You will also support research initiatives by creating experiments, comparing algorithms, tuning hyperparameters, and documenting results. In addition, you’ll share findings with the team, contribute to reports and presentations, and help onboard new team members. Through collaboration and ongoing learning, your work will help identify business and research opportunities, drive strategic decisions, and advance the field of AI at Cisco.

Minimum Qualifications

+ Currently enrolled in a PhD program in Computer Science, Artificial Intelligence, Machine Learning, or a related field.

+ Strong understanding of machine learning, deep learning, and natural language processing concepts, validated through academic, project, or professional work.

+ Experience training large language models (LLMs)—including modeling, optimization, fine-tuning, and serving—using Python and common AI libraries (e.g., TensorFlow, PyTorch, Hugging Face Transformers), evidenced through academic, project, or professional work.

Preferred Qualifications

+ Familiarity with agentic AI concepts, agent frameworks, and related applications.

+ Proficiency in software development, with experience in relevant programming languages (such as Python and Go) and associated tools.

+ Experience working with inference engines (e.g., vLLM, Triton, TorchServe) for LLM serving and optimization.

+ Familiarity with containerization and cloud platforms (such as Docker and AWS), as well as distributed systems for scaling and deploying AI models.

For non-sales roles, employees are also eligible to earn annual bonuses subject to Cisco’s policies.

Employees on sales plans earn performance-based incentive pay on top of their base salary, which is split between quota and non-quota components, subject to the applicable Cisco plan. For quota-based incentive pay, Cisco typically pays as follows:

+ .75% of incentive target for each 1% of revenue attainment up to 50% of quota;

+ 1.5% of incentive target for each 1% of attainment between 50% and 75%;

+ 1% of incentive target for each 1% of attainment between 75% and 100%; and

+ Once performance exceeds 100% attainment, incentive rates are at or above 1% for each 1% of attainment with no cap on incentive compensation.

For non-quota-based sales performance elements such as strategic sales objectives, Cisco may pay 0% up to 125% of target. Cisco sales plans do not have a minimum threshold of performance for sales incentive compensation to be paid.
