Company Description

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 a Senior System Engineer to support the Warhead Modernization Programs. Your primary focus will be to provide support for a set of high-level technical Systems Engineering activities, working with a group of systems engineering professionals, to provide project integration and management of requirements, mapping of designs, functions, failure mechanisms, risks, assessments and verifications to requirements. In this role, you will partner closely with design and test engineers as an integrated member of the design team to develop deep technical understanding of subsystem behavior, supporting the maturation of system requirements, participating in system-level design architecture and analysis, and contributing to test planning to verify requirements and qualify hardware, ensuring system-level requirements, interfaces, and verification approaches are technically sound and fully aligned with implementation.

These positions are in the Defense Technologies Engineering Division (DTED) within the Engineering Directorate, supporting the Weapon Technologies and Engineering (WTE) Program, within the Strategic Deterrence (SD) Directorate.

Depending on your assignment, these positions may offer a hybrid schedule, blending in-person and virtual presence. You may have the flexibility to work from home one or more days per week.
