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 System Engineer to support the Warhead Modernization Programs within the Systems Engineering and Integration (SE&I) group. 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 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), 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.

These positions will be filled at either level based on knowledge and related experience as assessed by the hiring team. Additional job responsibilities (outlined below) will be assigned if hired at the higher level.

• Define, track, and complete work objectives on time and within budget in collaboration with team. Monitor performance required to meet programmatic milestones and deliverables.
• Partner closely with design and test engineers to develop a deep technical understanding of subsystem behavior, ensuring system level requirements, interfaces, and verification approaches are technically sound and fully aligned with implementation.
• Support component specific technical requirements development including but not limited to performance requirements identification, interface requirements management, and traceability to verification activities. Participate in test planning to verify requirements and qualify hardware.
• Assist with system-level design architecture and analysis that combines component parts and subsystems into a complete functional system.
• Promote the systems engineering discipline and participate in hiring activities to support WTE and SD programs.
• Help ensure that program risks and requirements are communicated in an effective and timely manner to Leadership.
• Perform WTE and SD special assignments and represent the Programs and DTED at meetings, briefings, and committee activities both internal and external to the Laboratory.
• Perform other duties as assigned.

• May represent the organization by providing input on technical issues for specific projects and assist in influencing technical decisions made by management, based on SE&I activities.
• May provide guidance and/or informal mentoring to less-experienced team members.
