Java Engineering Intern - Fall 2026

NVIDIA is looking for Java engineering interns to work on cuVS, a suite of open‑source software libraries for unstructured data processing and vector search algorithms on GPUs. cuVS relies on NVIDIA CUDA for low‑level compute optimization, but exposes that high‑performance GPU compute through user‑friendly languages like Java. The team builds next‑generation building blocks for accelerating Java‑based libraries such as Lucene, JVector, and other widely used databases like OpenSearch, Solr, MongoDB, and Elasticsearch. What you’ll be doing: Analyze, design, and implement optimized GPU algorithms for large‑scale vector search, databases, and machine learning. Expand and improve integration of NVIDIA cuVS into relevant high‑level vector search libraries and vector databases. Perform performance analysis, benchmarking, and troubleshooting of associated libraries. What we need to see: Currently enrolled in a Masters or PhD program in Data Science, Machine Learning, or Computer Science. Strong analytical problem‑solving skills, algorithms, and mathematics fundamentals. Excellent software development skills: programming, debugging, performance analysis, and test design within the Java ecosystem and the JVM. Experience with NoSQL databases such as Lucene, Elasticsearch, OpenSearch, MongoDB, or Solr. Good communication and documentation habits. Ways to stand out from the crowd: Experience developing distributed algorithms and running them on distributed systems (HPC, Cloud, etc.). Experience with debugging multi‑language and multi‑hardware systems. Experience with vector databases such as Milvus, Pinecone, or LanceDB. Familiarity with nearest‑neighbor algorithms such as graph‑based and inverted file indexes. Some familiarity with machine learning concepts like clustering and dimensionality reduction. GPU programming knowledge is a plus; if you don’t have it, we’re happy to teach you. Internship hourly rates are standard pay based on the position, your location, year in school, degree, and experience. The hourly rate for our interns is USD 20 – 71. You will also be eligible for Intern benefits. NVIDIA is committed to fostering an inclusive work environment and is proud to be an equal‑opportunity employer.
