Research Associate (Levels II and III) - Zhou Lab

Protein Biochemistry and IDR Sample ProductionPosition SummaryThe Zhou Lab at the Buck Institute for Research on Aging is seeking an experienced Research Associate (level II and III) to support a multidisciplinary research program investigating the conformational and functional biology of intrinsically disordered proteins and regions (IDPs/IDRs).This is an experienced research position intended for a scientist capable of independently executing and optimizing technically demanding experimental workflows. The Research Associate will work closely with postdoctoral researchers and other members of the project team and will play a major role in large-scale protein production, quality control, sample preparation, and biochemical characterization.Key ResponsibilitiesCarry out protein expression, purification, and quality control for a large collection of IDR-containing proteins in human cellsOptimize purification and handling protocols for proteins that may be unstable, aggregation-prone, highly charged, or structurally heterogeneousPerform routine and advanced protein characterization and maintain standardized QC criteria across protein batchesPrepare and document samples for transfer to collaborating laboratories performing single-molecule profiling, HDX-MS, protein-interactome, and related assaysSupport in vitro protein interaction, condensation, aggregation, and binder-characterization experimentsMaintain detailed sample inventories, batch records, QC documentation, and transfer manifestsAssist with implementation and scaling of reproducible experimental workflowsWork closely with the postdoctoral fellow to troubleshoot experimental problems and improve throughput and reproducibilityContribute to preparation of technical reports and milestone documentationREQUIRED QUALIFICATIONSBachelor's or Master's degree in biochemistry, molecular biology, biotechnology, chemistry, protein science, or a related field, with substantial relevant research experienceExtensive hands-on experience in recombinant protein expression and purificationDemonstrated ability to independently execute established protocols and troubleshoot technically challenging experimentsStrong laboratory organization, record keeping, and sample-management skillsExperience managing multiple experimental samples or workflows in parallelAbility to work collaboratively in a fast-moving multidisciplinary research environmentPREFERRED QUALIFICATIONSDirect experience purifying and handling intrinsically disordered proteins or IDR-containing proteins is highly preferredExperience with difficult, aggregation-prone, low-complexity, or phase-separating proteinsExperience with affinity chromatography, ion exchange, SEC, protein concentration/formulation, electrophoresis, and quantitative protein assaysExperience preparing samples for mass spectrometry, HDX-MS, structural biology, or other high-end analytical platformsExperience establishing standardized protein-production or QC workflowsFamiliarity with automation or high-throughput protein production would be advantageousThis position would be an excellent fit for an experienced research professional who enjoys hands-on experimental work and building reliable protein-production pipelines.Compensation & BenefitsAnnual salary: RA II $65,000 - $80,000; RA III $70,500 - $90,000 depending on skills and experienceComprehensive benefits including medical/dental/vision coverage, paid time off, paid parental leave, 401(k) employer contribution, and a student debt repayment optionABOUT THE BUCKThe Buck Institute for Research on Aging is the first independent biomedical research institute in the United States devoted solely to research on aging. Located in Novato, California, the Buck brings together scientists across multiple disciplines to study the mechanisms of aging and age-related disease to help people live better, longer.The Buck Institute is an equal opportunity employer. We strongly encourage applications from candidates whose experiences and perspectives will contribute to the diversity and excellence of our community.TO APPLYPlease submit online:A curriculum vitae or resumeA cover letter addressing your past research experience, plans, and expectations for working in the lab
