Autonomous Sensors Mechanical Engineer

Overview 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. LLNL is a place where your expertise can make a real impact. This opening is for a Mechanical Engineer to support the Autonomous Sensors Group within the National Security Engineering Division (NSED). The group develops advanced sensing technologies and integrated systems for national security applications, focusing on multistatic, ultra-wideband sensing systems with modular, scalable architectures and compact form factors. These systems enable real-time data acquisition, imaging, and detection with visualization tools to support rapid operator understanding and decision-making. Solutions are designed to operate across mobile and autonomous platforms and adapt to a range of operational environments and mission needs. This position requires full-time on-site presence due to the nature of the work. Responsibilities Design, develop, and support mechanical systems and hardware for advanced sensing platforms, including sensor arrays and modular enclosures. Integrate mechanical subsystems into mobile and autonomous platforms operating in laboratory and field environments. Perform analysis, testing, and evaluation of mechanical designs to ensure performance, durability, and environmental robustness. Collaborate with multidisciplinary teams to develop integrated sensing solutions. Develop mechanical designs, models, and documentation to support system development and deployment. Support prototyping, fabrication, and assembly of hardware systems for laboratory and field use. Execute field testing activities, including system setup, troubleshooting, and data collection. Document designs, analyses, and test results to support program deliverables and milestones. Additional Responsibilities (SES.2 Level) Independently design and develop moderately complex mechanical systems and subsystems for sensing platforms. Lead integration of mechanical components across subsystems and contribute to system-level performance optimization. Apply engineering judgment to evaluate design trade-offs and recommend solutions to moderately complex technical challenges. Qualifications Ability to secure and maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship. Bachelor’s degree in Mechanical Engineering or related field or the equivalent combination of education and related experience. Fundamental knowledge of mechanical engineering principles, including design, materials, and manufacturing processes. Fundamental knowledge and experience using SolidWorks or similar CAD software for mechanical design. Ability to apply standard engineering techniques to solve well-defined technical problems. Sufficient written and verbal communication skills to collaborate within a multidisciplinary team environment. Ability to work under general direction in a dynamic, team-based research and development environment. Ability to travel to support offsite field work. Additional Qualifications (SES.2 Level) Comprehensive knowledge and broad application of mechanical engineering principles to solve moderately complex problems for sensing platforms. Experience independently designing and developing mechanical systems for real-world or fielded applications, including consideration of environmental constraints. Demonstrated ability to work under limited direction and exercise independent judgment in selecting methods, techniques, and evaluation criteria. Experience contributing to multidisciplinary system integration efforts and providing technical input to design trade studies and performance optimization. Desirable Qualifications Experience with sensor systems, RF hardware packaging, or integrated hardware platforms. Experience designing modular or scalable hardware systems. Familiarity with autonomous or unmanned systems (e.g., ground or aerial platforms). Experience supporting field testing, deployment, or prototype development in operational environments. Knowledge of operational environments requiring robust, ruggedized, and deployable engineering solutions. Pay Range $121,830 - $185,544 Annually

• 121,830 - $154,500 Annually for the SES.1 level
• 146,340 - $185,544 Annually for the SES.2 level
