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.

Job Description

We have an opening for a Mechanical Engineer to join our Precision Systems & Manufacturing Group. You will apply mechanical engineering principles to contribute to and/or lead projects ranging from novel research initiatives to supporting stockpile stewardship programs. These efforts will include the design and implementation of hardware and mechatronic solutions to program-critical problems, development and execution of instrumentation and testing platforms used to validate technology advances, assessment and iteration of designs based on testing data, and beyond. You will become familiar with the ongoing priorities of the programs being supported and assist in developing proposals for future contributions to the success of program objectives. Projects may involve requirements that are beyond commercially available capabilities and solutions may require modifications to commercial tools or development of advanced tools, sensors, and fabrication methods. When available technology is inadequate to meet current or future program needs, forward thinking will be essential for envisioning directions for technology development. This position is in the Material Engineering Division (MED), within the Engineering Directorate. This position requires full-time on-site presence due to the nature of the work. You will

Work under general direction to develop, implement, and qualify unique hardware solutions of limited complexity in support of various research and programmatic applications, including Volumetric Additive Manufacturing, robotic and mechatronic systems, and drone systems.
Execute testing and validation plans involving the creation of mechanical hardware, integration of sensors and actuators, and utilization of data acquisition equipment.
Provide engineering solutions for the fabrication of components, including tooling design, procedure development, and assembly integration.
Generate and interpret mechanical specifications and mechanical drawings.
Perform engineering calculations to support design, fabrication, and/or assembly operations.
Analyze and interpret test data to provide insight on test results.
Work independently under general direction and collaboratively as part of a team.
Present technical approaches, project plans, and documentation to peers and program managers.
Work with project leadership to develop clear design goals and constraints to solve design challenges.
Perform other duties as assigned.

Qualifications

Ability to obtain 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 and previous experience in hardware integration and testing, including sensors, actuators, control systems, and/or data acquisition systems, with the ability to apply these to both new and existing processes/equipment.
Fundamental knowledge and previous experience in the design, analysis, and fabrication of mechanical components and/or assemblies.
Fundamental knowledge and previous experience in the design and implementation of Volumetric Additive Manufacturing systems.
Previous experience in the application and integration of robotic and mechatronic systems.
Fundamental knowledge and previous experience in command and control of drone systems associated with data collection operations.
Ability to work independently and collaboratively as part of a team with effective organizational and interpersonal skills.
Sufficient verbal and written communication skills necessary to effectively collaborate in a team environment and present and explain technical information.

Qualifications we desire

Fundamental knowledge and previous experience in the selection and implementation of varied material systems for use in Additive Manufacturing processes.

Pay Range:
