Job Description

We have an opening for a Semiconductor Laser Device Engineer with expertise in semiconductor laser diodes. You will define, develop, and deploy high power laser diode arrays.  You will have an advanced understanding of semiconductor optoelectronics to specify, design, and oversee deployment of high-power laser diode arrays and work to determine requirements, set specifications and address array technology options including thermal management and electronic drivers.  You will work with LLNL team members to expand the vision for continued development of diode laser technology. This position is in the Laser Systems Engineering & Operations (LSEO) Division of the Engineering Directorate.

This position will be filled at either level (SES.2 or SES.3) based on knowledge and related experience as assessed by the hiring team. Additional job responsibilities at the SES.3 level (outlined below) will be assigned if hired at that level.

In this role, you will

• Work under limited direction with moderate responsibility, use comprehensive knowledge, and exercise independent judgment to determine methods and recommend improvements within established frameworks and contribute to the fulfillment of project and organizational goals.
• Provide engineering support for the design, build, and execution of laboratory experiments for characterizing high power semiconductor diode lasers.
• Assist in maintaining test instrumentation cross-calibration, documenting test procedures, archiving test results, updating analysis software, and defining appropriate database reports.
• Perform data analysis of test results and write analysis codes in support, as needed.
• Participate in performing optical, electronic, and thermal modeling in support of experimental efforts.
• Contribute to the LLNL technical team on diode laser pump development and procurement contracts; collaborate closely with the laser team to ensure successful on-time deployment of the diode pump subsystem.
• Prepare and author moderately complex technical documents and presentations.
• Support engineering operations and participate in defining process improvements.
• Contribute to research into new approaches to record high power semiconductor diode lasers.
• Select methods, techniques, and evaluation criteria to recommend improvements and conduct moderately complex experiments to characterize subcomponents.
• Participate in the fielding of these new systems on Inertial Confinement Fusion (ICF) physics platforms and other high-energy laser platforms.
• Perform other duties as assigned.

Additional job responsibilities, at the SES.3 level:

• Function independently with minimal direction, taking significant responsibility and using advanced knowledge and judgment to establish objectives, prioritize parallel tasks, allocate resources, and collaborate in the development of innovative methods/technology to guide the completion of projects and contribute to the development of organizational goals.
• Design, build, and commission a large range of complex semiconductor laser characterization tools and experiments.
• Design and execute complex experiments to characterize laser diode components.
• Develop, implement, and utilize advanced data analysis and simulation software to support experimental goals and provide solutions to complex problems.
• Guide the completion of a project, establish project objectives and strategy, and influence technical direction by applying high-level technical concepts and techniques to drive successful outcomes
