Join us and make YOUR mark on the World!

Lawrence Livermore National Laboratory (LLNL) has turned bold ideas into world‑changing impact advancing science and technology to strengthen U.S. security and promote global stability.

Our mission spans four critical national security areas nuclear deterrence, threat preparedness, energy security, and multi‑domain defense empowering teams to take on the toughest challenges of today and tomorrow. With a culture built on innovation and operational excellence, LLNL is a place where your expertise can make a real impact.

We have multiple openings for graduate students to join the Cyber and Critical Infrastructure Summer Institute (CSI) and to work on topics related to cybersecurity that align with LLNL's national security missions. The 2026 CSI program will run during the summer with a range of start dates between May 18, 2026, and June 22, 2026, and flexible end dates through September 25, 2026.

CSI is designed to provide selected candidates an opportunity to apply their skills to projects in areas of national importance such as the development and implementation of cybersecurity tools and capabilities to mitigate advanced threats and the cybersecurity of civilian and defense critical infrastructure. The program will include opportunities to participate in professional and technical development activities with lab Subject Matter Experts, network with fellow interns and lab employees, and learn about the breadth of LLNL's support to US national security.
