A healthier future. It’s what drives us to innovate. To continuously advance science and ensure everyone has access to the healthcare they need today and for generations to come. Creating a world where we all have more time with the people we love. That’s what makes us Genentech!
Join our global Analytical Development and Quality Control team as a Technical Development Principal Scientist, Mass Spectrometry Characterization Lead, driving analytical strategies that transform cutting-edge biologic therapeutics from early development to commercialization. In this role, you will bridge strategic leadership with hands-on laboratory expertise within a collaborative, multidisciplinary environment dedicated to delivering life-changing medicines. You will lead mass spectrometry characterization, solve complex analytical challenges, and guide cross-functional teams with scientific excellence and impact.
The Opportunity
- Lead the mass spectrometry (MS) characterization strategy and execution across all stages of biologic therapeutic development, from early development through to commercial launch.
- Design, execute, and interpret complex liquid chromatography-mass spectrometry (LC-MS) analyses to establish deep structural understanding of protein modalities and resolve technical root causes.
- Develop and implement phase-appropriate MS methods and advanced multi-attribute method (MAM) strategies where standard analytical assays fall short.
- Identify, monitor, and quantify critical quality attributes (CQAs) and post-translational modifications (PTMs) to ensure reliable analytical control.
- Support process development milestones, including cell line selection, purification, formulation, stability, minor variant characterization, and structure-function elucidation.
- Author filing-ready MS characterization sections for global regulatory submissions (IND, BLA, and MAA) and represent technical packages in regulatory interactions.
- Collaborate closely with multidisciplinary teams, analytical leads, and external research/manufacturing partners to achieve project delivery milestones.
- Mentor scientific team members in MS data interpretation and champion modern analytical capabilities and best practices.
Who you are
You hold a Ph.D. with 4–6+ years of relevant experience, or an M.S./B.S. with 6–10+ years of experience in Analytical Chemistry, Biochemistry, Chemical Engineering, or a related field. You bring deep analytical expertise in liquid chromatography-mass spectrometry (LC-MS) applied to the characterization of proteins or related therapeutic modalities. You possess strong working knowledge of chemistry, manufacturing, and controls (CMC) drug development and regulatory filing processes (IND/BLA). You demonstrate excellent collaborative, organizational, and communication skills, thriving both as an independent lead and as part of a dynamic, multidisciplinary team. You are an agile problem-solver motivated by scientific curiosity, technical quality, and delivering meaningful results in a fast-paced environment.
Relocation benefits are available for this job posting.
The expected salary range for this position based on the primary location of South San Francisco, CA is $120,800 - $224,300. Actual pay will be determined based on experience, qualifications, geographic location, and other job-related factors permitted by law. A discretionary annual bonus may be available based on individual and Company performance. This position also qualifies for the benefits detailed at the link provided below.

Which companies in California sponsor visas for lead scientists?
California's largest visa sponsors for lead scientist roles include Genentech, Gilead Sciences, Illumina, and Amgen in biotechnology; Applied Materials, Lam Research, and Intel in semiconductor research; and national laboratories such as Lawrence Berkeley and Lawrence Livermore. University of California campuses also sponsor research scientists through both employment and exchange visitor programs. Sponsorship patterns vary by company size, funding cycle, and the specific research discipline involved.
What visa types realistically cover lead scientist roles in California?
Lead scientist positions typically qualify as specialty occupations under the H-1B visa, requiring at least a bachelor's degree in a directly related scientific field. Chilean nationals may qualify under the H-1B1 and Singaporean nationals under H-1B1 Singapore, both uncapped alternatives. Australian nationals can pursue the E-3 visa. EB-2 and EB-3 employment-based green cards are common long-term paths, often using PERM labor certification. J-1 visa research scholar status suits postdoctoral and visiting scientist appointments at universities and national labs.
How to find lead scientist visa sponsorship jobs in California?
Migrate Mate lists California lead scientist roles specifically filtered to employers with verified visa sponsorship history, covering biotech clusters in South San Francisco and San Diego, semiconductor research in Silicon Valley, and national laboratory positions. Searching by city or research discipline on Migrate Mate lets you identify which employers are actively filing for scientist-level roles rather than sifting through postings where sponsorship status is unclear.
Which California cities have the most lead scientist sponsorship jobs?
South San Francisco and the broader San Francisco Bay Area concentrate the highest volume of sponsored lead scientist roles, driven by the biotech corridor anchored by Genentech and dozens of smaller biopharmaceutical companies. San Diego is a strong second, with Illumina, Pfizer's local operations, and a dense cluster of genomics and life sciences firms. Silicon Valley adds semiconductor and materials science roles. Los Angeles and the greater Pasadena area, home to Caltech-affiliated research, also generate consistent openings.
Are there California-specific factors that affect visa sponsorship for lead scientists?
California's high concentration of NIH-funded research institutions, venture-backed biotech startups, and Department of Energy national laboratories creates sponsorship demand that extends well beyond large corporations. Startups at Series B stage and beyond regularly sponsor H-1B holders for lead scientist roles, particularly in South San Francisco and San Diego. California's UC system also feeds a strong postdoctoral pipeline that frequently transitions into industry sponsorship. State-level employment law does not restrict employer-sponsored visa filings, so federal visa rules govern entirely.
What is the prevailing wage for sponsored lead scientist jobs in California?
U.S. employers sponsoring a visa must pay at least the prevailing wage, which is what workers in the same role, area, and experience level typically earn. The Department of Labor sets this rate to make sure companies aren't hiring foreign workers simply because they'd accept lower pay than a U.S. worker. It varies by job title, location, and experience. You can look up current prevailing wage rates for any occupation and location using the OFLC Wage Search page.
