What Your Job Will Be Like: Are you looking for an exciting opportunity to do important and creative research? Sandia California’s Biomanufacturing and Biomaterials department is seeking a dedicated and hardworking Postdoctoral Scientist with expertise in chemistry and chemical engineering to join the Joint BioEnergy Institute (JBEI) Pretreatment Optimization and Process Integration team to develop novel technologies for the efficient feedstock-agnostic deconstruction of lignocellulose into fermentable carbon. We are currently developing lignin deconstruction technologies using novel solvents (ionic liquids, deep eutectic solvents and molecular solvents). The selected candidate will continue these efforts and develop technologies to efficiently extract and fractionate lignin from engineered woods and grasses into molecules that can be further upgraded chemically and/or biochemically into valuable products. The candidate may also conduct limited work on hydrolysate fermentation and biocompatibility. We are seeking an individual with proficiency in chemical catalysis, especially one with previous experience with lignocellulose, and who can work with biochemists and microbiologists to explore integration of biomass pretreatment and deconstruction with bioconversion. This will be a multi-disciplinary effort, with opportunities to work with a wide range of experts in national labs and industry to conduct state-of-the-art R&D in lignocellulosic biofuels. On any given day, you may be called on to: + Design and screen solvents capable of extracting and deconstructing lignin from lignocellulose. + Develop catalysts to depolymerize lignin fractionated from different pretreatments. + Characterize lignin streams and collaborate with microbiologists to develop methods to upgrade depolymerized lignin into bioproducts. + Participate in laboratory management and mentoring student interns. + Present results at project meetings and conferences. Qualifications We Require: + PhD in Chemistry, Chemical Engineering, Fermentation, or a closely related field + The ability to conduct and communicate creative, independent research as identified through a record of high technical accomplishments (e.g., publication in high-impact scientific journals, presentations at national/international conferences, etc.) Qualifications We Desire: + Proven experience with biomass pretreatment and separations + Experience with process development and optimization + Experience with solvent recovery and recycle through evaporative or membrane technologies + Strong analytical characterization background (2D NMR, GC-MS, LC-MS, GPC, NIR, FTIR) + Handling high pressure reactors and in-line process monitoring; + Experience with fermentation of lignocellulosic hydrolysates + Experience in research with set timelines and the ability to conduct creative, independent research + Strong written and oral communication skills About Our Team: The Biomanufacturing and Biomaterials department is dedicated to developing and advancing innovative technologies for producing the next generation of biofuels and biomaterials. Our multidisciplinary staff represents a diverse range of backgrounds and skill sets: molecular biology, chemistry, chemical and biochemical engineering, biophysics, computational science, and biochemistry. We partner broadly with other Sandia departments as well as other national laboratories, industry, and universities to develop practical, science-based solutions to national energy goals. We play an essential role in the DOE Joint BioEnergy Institute (JBEI), one of three Bioenergy Research Centers in the Nation advancing the next generation of biofuel technologies. JBEI is a multi-organizational research center comprising world-class resources and expertise located in one facility at Emeryville, California.

Security Clearance:

This position does not currently require a Department of Energy (DOE) security clearance. Sandia will conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Furthermore, employees in New Mexico need to pass a U.S. Air Force background screen for access to Kirtland Air Force Base. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause access to be denied or terminated, resulting in the inability to perform the duties assigned and subsequent termination of employment. If hired without a clearance and it subsequently becomes necessary to obtain and maintain one for the position, or you bid on positions that require a clearance, a pre-processing background review may be conducted prior to a required federal background investigation. Applicants for a DOE security clearance need to be U.S. citizens. If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain a security clearance may be impacted. Members of the workforce (MOWs) hired at Sandia who require uncleared access for greater than 179 days during their employment, are required to go through the Uncleared Personal Identity Verification (UPIV) process. Access includes physical and/or cyber (logical) access, as well as remote access to any NNSA information technology (IT) systems. UPIV requirements are not applicable to individuals who require a DOE personnel security clearance for the performance of their SNL employment or to foreign nationals. The UPIV process will include the completion of a USAccess Enrollment, SF-85 (Questionnaire for Non-Sensitive Positions) and OF-306 (Declaration of for Federal Employment). An unfavorable UPIV determination will result in immediate retrieval of the SNL issued badge, removal of cyber (logical) access and/or removal from SNL subcontract. All MOWs may appeal the unfavorable UPIV determination to DOE/NNSA immediately. If the appeal is unsuccessful, the MOW may try to go through the UPIV process one year after the decision date. EEO: All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, or veteran status and any other protected class under state or federal law.
