Job summary

Zymo Research Corporation is seeking a postdoctoral research scientist to join the Epigenetics Technology group in Irvine, CA. The role focuses on developing molecular and sequencing methods to study genetic variants, DNA damage, and genome instability in cancer and other diseases.

The position combines wet-lab molecular biology with sequencing library preparation and DNA damage mapping, offering opportunities to contribute to invention disclosures, patents, and peer-reviewed publications.

Qualifications

• Ph.D. in molecular biology, biochemistry, cancer biology, genetics, genomics, or a related field.
• Direct research experience in cancer biology or cancer genomics, including cancer-associated mutations or genome instability.
• Experience in probe-enrichment assays followed by NGS (e.g. exome-sequencing).
• Demonstrated hands-on NGS methods development experience, including library preparation design, optimization, troubleshooting, and quantitative performance evaluation.

Responsibilities

• Design and execute original methods development projects addressing disease-associated variants and genome integrity.
• Develop and troubleshoot NGS library preparation workflows and molecular assays; optimize nucleic acid handling and sequencing quality control.
• Develop and evaluate approaches for DNA damage and structure mapping, distinguishing biological signals from sample handling artifacts.
• Provide scientific guidance, draft manuscripts and invention disclosures, and contribute to patent-related documentation.

Job description

Job Summary:

Zymo Research is seeking a postdoctoral research scientist to join the Epigenetics Technology group and develop innovative molecular and next-generation sequencing (NGS) methods to investigate genetic variants, genomic abnormalities, DNA damage, and genome instability in cancer and other diseases. This hands-on role combines strong molecular biology and enzymology with sequencing library preparation and experimental DNA damage and structure mapping.

The scientist will pursue high-risk, high-reward methods development, moving from scientific hypotheses through feasibility testing, optimization, and analytical validation. The role requires direct cancer research experience and the ability to work independently through technical uncertainty. The scientist will contribute to invention disclosures, patent applications, and peer-reviewed manuscripts. Experience in epigenetics is valuable but is not required.

Join us in making a meaningful impact!

Essential Duties and Responsibilities

• Design and execute original methods development projects addressing disease-associated variants, genomic abnormalities, and genome integrity. Define testable hypotheses, appropriate controls, milestones, and criteria for continuing, revising, or stopping an experimental approach.
• Develop and troubleshoot NGS library preparation workflows and molecular assays. Optimize nucleic acid handling (e.g. minimizing DNA damage), enzymatic processing, adapter incorporation, amplification and quality control to improve molecule recovery, accuracy, complexity, and reproducibility.
• Develop and evaluate experimental approaches for DNA damage and structure mapping (R-loops, D-loops). Distinguish biological signals from changes introduced during sample handling, extraction, storage, or library preparation using appropriate controls and independent measurements.
• Apply enzymology to characterize and optimize nucleic acid-modifying enzymes. Assess activity, specificity, substrate dependence, kinetics and reaction compatibility; collaborate with the protein team on enzyme selection and improvement.

Research Validation and Scientific Outputs

• Validate methods using defined standards, reference materials and model systems (e.g. cancer cell lines). Assess sensitivity, specificity, precision, background error, and robustness across sample quality and input levels.
• Work with bioinformatics scientists to interpret sequencing data, assess variants/SNPs, DNA damages/structures and mapping accuracy, and investigate sources of bias. Integrate experimental and computational evidence when refining assay performance.
• Maintain traceable records, communicate findings and technical risks, and document reproducible methods. Draft scientific manuscripts, prepare invention disclosures, and contribute experimental evidence and technical writing for patent applications with relevant teams.
• Provide scientific guidance to supporting researchers and contribute to other projects requiring relevant expertise. Balance exploratory research with clear feasibility decisions and practical development goals.

Supervisory Responsibilities and Core Competencies

• Provide scientific guidance and training to potential Research Associates and Interns. Demonstrate creativity, scientific rigor, sound judgment, persistence through uncertainty, clear communication, and collaborative problem-solving.

Education and Experience:

• Ph.D. in molecular biology, biochemistry, cancer biology, genetics, genomics, or a related field, with first-authored peer-reviewed publications demonstrating original scientific contributions.
• Direct research experience in cancer biology or cancer genomics, including cancer-associated mutations or genomic abnormalities and DNA damage, repair, or genome instability.
• Experience in probe-enrichment assays followed by NGS (e.g. exome-sequencing).
• Demonstrated hands-on NGS methods development experience, including library preparation design, optimization, troubleshooting, and quantitative performance evaluation.

Required Scientific and Technical Skills

• Strong molecular biology background, including DNA manipulation, primer and probe design, PCR and qPCR, adapter ligation, nucleic acid purification, and DNA and sequencing library quality control.
• Strong enzymology background with practical experience developing biochemical assays, interpreting enzyme activity and substrate specificity, and optimizing reaction conditions and multi-enzyme workflows.
• Understanding of genetic variation, structural and copy-number abnormalities, DNA damage, and genome instability in disease with an emphasis on cancer. Ability to distinguish biological variation from damage-related and sequencing artifacts.
• Ability to independently design rigorous experiments, analyze quantitative data, challenge assumptions and adapt approaches when results do not support the initial hypothesis.
• Strong scientific writing and communication skills, including the ability to explain/present novel methods, document results clearly, and contribute to peer-reviewed manuscripts and patent-related technical documentation.

Preferred Qualifications

• Experience with low-input (cfDNA) or damaged DNA (FFPE), disease-relevant model systems, or clinical research specimens.
• Experience with error-controlled sequencing, targeted enrichment, digital PCR, enzyme characterization or engineering, or advanced sequencing approaches (PacBio, Nanopore).
• Experience in epigenetics or DNA methylation/hydroxymethylation.
• Familiarity with sequencing data analysis (Bash / web-based Galaxy), statistics, R, or Python.
• 10 years of relevant post-doctoral or professional research experience in a related field, preferably within cancer genomics, molecular biology, or a closely related discipline is a plus
