We are seeking highly motivated, soon-to-graduate MS or Ph.D. students in Computer Science, Machine Learning, Data Science, or related fields to join us as AI / ML Engineering Interns.

This internship is ideal for candidates who are eager to learn how large-scale AI systems are built and deployed in production. You will work closely with experienced engineers and data scientists to help build the Intelligence Layer and Data Consortium that power DataVisor's real-time fraud detection platform. 

This internship focuses on distributed systems, data pipelines, machine learning infrastructure, and applied AI, including exposure to agentic flows and large language models (LLMs).

What You'll Do

• Data Engineering & Pipelines
• Assist in building and maintaining high-throughput data pipelines using technologies such as Spark, Kafka, or Flink
• Help process and aggregate real-time signals (e.g., device fingerprints, behavioral data) into shared intelligence systems
• Distributed Systems & Scalability
• Learn to design and optimize backend systems that support large-scale, real-time decisioning
• Contribute to improving system performance, reliability, and latency under high transaction volumes
• AI Applications & Agentic Flows
• Support the development of AI applications and agentic workflows using state-of-the-art LLMs (e.g., OpenAI, Anthropic, Google)
• Experiment with natural language interfaces, intelligent rule suggestions, and automated strategy generation
• Machine Learning Pipelines
• Help deploy and monitor pipelines for unsupervised and supervised ML models
• Assist with integrating models into real-time scoring APIs and decision engines
• Privacy & Security
• Learn best practices for privacy-first system design, including tokenization and hashing to protect sensitive data
• Cross-Functional Collaboration
• Work alongside Data Science, Product, and Engineering teams to test ideas, validate models, and ship production features
