INTRODUCTION
The laboratory of Dr. Kai Zhou at the Buck Institute for Research on Aging seeks a hands-on mass spectrometry scientist or postdoctoral researcher to establish and operate a structural mass spectrometry platform. We welcome candidates with expertise in native mass spectrometry, crosslinking mass spectrometry, HDX-MS, or intact-protein/top-down analysis. Our laboratory investigates how protein structure, interactions, and assembly change with aging and disease. Projects include intrinsically disordered proteins (IDR/IDPs), protein complexes, and ribosomes. The successful candidate will take substantial ownership of instrument operation, method development, data quality, and biological interpretation. The role offers opportunities to develop new workflows and pursue scientific questions in collaboration with protein biochemists, structural biologists, and computational researchers.
LOCATION
Location: Novato, CA (on-site)
Responsibilities
- Establish, optimize, and run structural-MS workflows, including low-flow LC for bottom-up proteomics and crosslinking, and a separate LC workflow for intact-protein and native MS analysis
- Develop native-MS and/or crosslinking-MS methods to characterize protein-complex composition, stoichiometry, interactions, and structural changes. Explore intact-complex analysis and complex-down MS workflows where experimentally feasible
- Prepare and evaluate samples, including buffer exchange, desalting, crosslinking, digestion, and enrichment as appropriate; optimize native SEC or rapid online buffer exchange while assessing sample integrity and complex stability
- Optimize ionization, ion transmission, precursor isolation, and fragmentation for heterogeneous proteins and assemblies; assess instrument performance, troubleshoot problems, and coordinate maintenance and training with vendor specialists
- Establish quality-control standards, reproducible protocols, and reliable workflows for increasing sample throughput, including automated or unattended acquisition, batch QC, carryover checks, and reproducible switching between native and denaturing analyses
- Analyze and interpret spectra with appropriate controls, uncertainty assessment, and validation; distinguish solution-state interactions from source-induced dissociation or adducts and assess crosslink identifications and proteoform/PTM assignments as appropriate
- Maintain clear experimental records and organize raw data, analysis files, and protocols
- Collaborate on experimental design, train colleagues, and contribute to publications and consortium deliverables
BASIC QUALIFICATIONS
Required
- PhD in analytical chemistry, biochemistry, biophysics, structural biology, or a related discipline. Experienced master’s-level applicants with substantial independent instrument-operation and method-development experience may be considered for an appropriate staff appointment
- Demonstrated hands-on operation of a high-resolution mass spectrometer, including acquisition-method setup, performance assessment, and troubleshooting
- Substantial practical expertise in at least one of the following: native MS, crosslinking MS, HDX-MS, or intact-protein/top-down MS
- Experience connecting sample preparation, acquisition settings, data analysis, and experimental controls to reliable conclusions
- Strong scientific reasoning, careful documentation, and the ability to work independently and collaboratively
PREFERRED QUALIFICATIONS
- Native electrospray, native MS, intact-protein/top-down or complex-down analysis, or multistage fragmentation
- Crosslinker selection, reaction optimization, enrichment, crosslinked-peptide identification, and false-discovery-rate assessment
- Recombinant protein purification, sample-integrity assessment, and troubleshooting aggregation or heterogeneity
- Analysis of disordered proteins, heterogeneous assemblies, or ribonucleoprotein complexes
- Workflow automation, quantitative analysis, or scripting for reproducible data processing; familiarity with crosslinking or proteoform-analysis software. Experience supporting complementary bottom-up proteomics or metabolomics applications is also welcome
Candidates need not have experience in every listed technique. We value demonstrated depth, ownership, and the ability to learn complementary approaches.
COMPENSATION, BENEFITS & ADDITIONAL INFORMATION
- Annual salary range: $75,920 - $85,500, commensurate with qualifications and experience
- Generous benefits package including health insurance, paid parental leave, vacation/sick, and 401(k) with 5% employer match
- Visa sponsorship (J visa) is available for this position
ABOUT THE BUCK INSTITUTE
Our success will ultimately change healthcare. At the Buck, we aim to end the threat of age-related diseases for this and future generations by bringing together the most capable and passionate scientists from a broad range of disciplines to identify and impede how we age. We are an independent, non-profit institution located in Marin County, CA, with the goal of increasing human healthspan, or the healthy years of life. Globally recognized as the pioneer and leader in efforts to target aging—the number one risk factor for diseases including Alzheimer’s, Parkinson’s, cancer, macular degeneration, heart disease, and diabetes—the Buck seeks to help people live better longer. We are an equal-opportunity employer and strive to create an atmosphere where diversity of identity, experience, and background is welcomed, valued, and supported. Candidates who contribute to this diversity are strongly encouraged to apply.
TO APPLY
- Please submit a CV, a brief cover letter, and contact information for three references
- Postdoctoral applicants, please include your completed or expected PhD date
- In your cover letter, describe one representative MS project and specify:
+ The instrument and techniques you used
+ Which sample-preparation, acquisition, troubleshooting, and analysis steps you personally performed
+ A technical problem you solved and how you verified the solution
+ Your scientific contribution and the resulting publication, method, dataset, or operational improvement

Entry level postdoctoral research scientist positions are typically open to candidates who have recently completed or are finishing a doctoral degree in a relevant field. Hiring committees at this stage look for a clear research focus, at least one first-author publication or strong conference presentation, and demonstrated laboratory or computational skills. A well-written research statement and strong faculty references carry significant weight for new applicants.
Which companies hire entry level postdoctoral research scientists?
Companies hiring entry level postdoctoral research scientists right now include UT Southwestern Medical Center, Howard Hughes Medical Institute (HHMI), and Cedars-Sinai Medical Center, based on current listings on Migrate Mate as of November 2026. At this level, hiring comes from a wide range of organizations, including research universities, national laboratories, biotech and pharmaceutical companies, and government research agencies that run structured postdoctoral fellowship programs.
Are there remote entry level postdoctoral research scientist jobs?
Yes, though most postdoctoral research roles are lab- or campus-based, remote and hybrid options do exist, particularly in computational biology, data science, and policy-focused research positions. About 5% of entry level postdoctoral research scientist openings are remote or hybrid as of November 2026, so candidates with skills in modeling, bioinformatics, or quantitative analysis have the best chances of finding flexible arrangements.
Are these new grad postdoctoral research scientist jobs?
Yes, these listings include new grad, recent graduate, and junior postdoctoral research scientist roles. A posting is typically new-grad friendly when it welcomes candidates who have just completed their PhD, accepts zero to two years of independent research experience, and considers strong graduate coursework, dissertation chapters, or doctoral internships in place of prior postdoctoral appointments. Look for language like 'recent doctoral graduates encouraged to apply' as a reliable signal.
Which industries hire the most entry level postdoctoral research scientists?
Entry Level postdoctoral research scientist roles concentrate in Education, Biotechnology & Pharmaceuticals, and Science & Research, based on current listings on Migrate Mate as of November 2026.
