Senior Semiconductor Laser Device Engineer
Company Description Lawrence Livermore National Laboratory (LLNL) is dedicated to fostering a culture that values individuals, talents, partnerships, ideas, experiences, and different perspectives, recognizing their importance to the continued success of the Laboratory’s mission. Pay Range $202,500 - $256,824 Annually Job Description We have an opening for a Senior Semiconductor Laser Device Engineer with expertise in semiconductor laser diodes. You will define, develop, and deploy high power laser diodes and diode arrays. You will have an advanced understanding of semiconductor optoelectronics, micro‑optics, and thermal management to specify, design, and oversee deployment of high‑power laser diode arrays and determine requirements, set specifications, and address array technology options including thermal management and electronic drivers. You will work with the LLNL team 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. In this role, you will Operate under consultative direction with substantial authority, using in‑depth analysis and subject‑matter expertise in highly advanced concepts, to resolve a diverse range of highly complex problems, independently determine strategies, modify approaches, and pursue actions that impact organizational operations or directions and achieve long‑term goals. Provide technical guidance to team members, leadership, and external customers on defining, developing, and deploying highly complex high‑power diode laser pump arrays. Serve as the primary technical contact, providing input and applying highly advanced technical knowledge for high‑power laser diodes and optoelectronic components. Set broad research/project vision and strategy and influence technical direction for self and others, serving as liaison between stakeholders to align priorities, goals, and resources, and to foster collaboration. Direct technical activities as needed to specify, procure, evaluate, and deploy commercially available laser diode arrays on LLNL systems. Build and sustain strategic relationships with universities and industrial partners to conduct highly advanced research into novel approaches for enhancing laser diode technology. Design and direct highly complex experiments to characterize laser diode components. Assess novel pump laser concepts using optoelectronic, optical, and/or thermal simulations. Provide highly advanced technical guidance, training, mentoring, and coaching to technical staff. Utilize highly advanced technical expertise and analytical skills to prepare, present, and explain formal and complex reports and written and verbal presentations of technical work. 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 Electrical Engineering, Physics, or related technical field, or the equivalent combination of education and previous relevant experience. Highly advanced knowledge of and significant experience with current state‑of‑the‑art laser diodes, including laser diode metrology, semiconductor device physics (gain, cavity design, heterostructure charge transport), and device reliability physics. Expert knowledge of and significant experience with laser diode micro‑optics, optoelectronic device packaging and thermal management, and knowledge of highly complex reliability engineering principles. Significant experience with highly complex optoelectronic device simulation and laser diode characterization. Expert communication, facilitation, and collaboration skills necessary to prepare, present, and explain highly complex reports and effectively deliver highly advanced technical presentations, as well as influence and advise senior management and/or external sponsors. Significant experience with demonstrated ability to successfully lead and manage small, multi‑disciplinary teams in achieving project objectives. Significant experience interacting and cooperating with all levels of technical staff, managers, and vendors. Qualifications We Desire Master’s degree or Ph.D. in Electrical Engineering or Physics. Experience with high power laser diode arrays, laser diode simulation software, laser diode current driver requirements, III‑V semiconductor fabrication and materials technologies, and/or opto‑electronic component packaging. Demonstrated experience leading a project and/or managing project budget and schedule. Expert knowledge of and experience with characterization of compound semiconductor optoelectronic devices and materials such as GaAs, InP, and/or GaN. Familiarity with the high‑power laser diode industry or employment experience at an industrial manufacturer or end‑user of laser diode components. Familiarity with compound semiconductor growth, characterization, and fabrication processes such as MOCVD, MBE, XRD, PL, ECV, AFM, SEM, Hall effect, and/or SIMS, PECVD, RIE, ICP, wet etch, photolithography, and/or evaporation. Experience in writing technical specifications and statements of work. Additional Information Position Information This is a Career Indefinite position open to Lab employees and external candidates.
