We have an opening for a  SEM/FIB Laboratory Manager  to operate, maintain, and advance scanning electron microscopy, focused ion beam, and dual-beam FIB/SEM capabilities. You will support materials characterization, sample preparation, micromachining, imaging, and analytical research for a broad user community. This position is in the MicroAnalytical Signatures Group within the Nuclear and Chemical Sciences Division. This position requires full-time on-site presence due to the nature of the work. This position 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. You will  Operate, maintain, troubleshoot, and support SEM, FIB, and dual-beam FIB/SEM systems for imaging, characterization, micromachining, cross-sectioning, and sample preparation. Develop, validate, document, and implement safe, repeatable FIB/SEM workflows and preparation methods for complex, scarce, high-value, time-sensitive, radioactive, or radiologically controlled samples. Perform manipulation, recovery, and characterization, while ensuring compliant handling of radiologically controlled materials. Diagnose and resolve instrument, software, vacuum, detector, and sample-related issues; coordinate preventive maintenance, repairs, vendor support, service contracts, and laboratory readiness. Improve throughput, reproducibility, data quality, automation, traceability, and accessibility through new capabilities, image-analysis tools, scripts, and data-processing pipelines. Establish and maintain microscopy data-management practices, including cataloging, metadata, provenance, backups, retrieval, and long-term preservation. Manage laboratory operations, documentation, scheduling, inventory, user access, safety, and resource allocation. Train and assist users; provide technical consultation, SOPs, guides, training materials, and outreach to internal and external collaborators. Perform other duties as assigned. Additional job responsibilities, at the SES.3 level Independently lead complex SEM/FIB technical work involving ambiguous requirements, competing priorities, and multiple instrument, sample, workflow, and data-quality considerations.
