Job Description
Job Title: Research Associate I/II, Assay Development
Location: San Carlos, CA (fully on-site)
Commitment: Full-time
Reports to: Founding Scientist, Assay Development
Posted: September 2026
About Us:
Resero Bio is an emerging precision diagnostics company pioneering the next generation of liquid biopsies by unlocking the cell-free transcriptome. Our patented RARE-seq technology enables ultra-sensitive detection and characterization of cancer from blood and urine, offering a non-invasive window into dynamic cancer biology. Founded in 2025 and backed by top-tier investors, we are bringing this technology into clinical practice.
Role Overview:
The Research Associate is responsible for hands-on processing of clinical and biobank specimens through the full laboratory workflow, from sample receipt through sequencing-ready libraries. This role is ideal for someone who thrives in a fast-paced research environment and brings exceptional attention to detail, consistency, and care to every sample processed.
Key Responsibilities:
• Biobank and process urine, plasma, and tissue specimens
• Perform molecular biology workflow end-to-end including cell free nucleic acid extraction and NGS library preparation
• Perform and analyze quantification and quality control (Qubit, Fragment Analyzer / TapeStation, RT-qPCR)
• Maintain accurate sample and aliquot tracking through the workflow in accordance with naming conventions and chain-of-custody SOPs
• Document results in the electronic laboratory notebook and prepare run-level summaries
• Support research projects with external collaborators, including preparation of study summaries
• Contribute to assay development, optimization, and process improvement as the platform scales
Qualifications:
• BS or MS in molecular biology, biochemistry, bioengineering, genetics, or a related field
• Prior hands-on wet laboratory experience
• Proficiency in core molecular biology technique, including accurate pipetting, PCR/qPCR, nucleic acid extraction, and gel or capillary electrophoresis
• Strong organizational skills and attention to detail, with demonstrated care in maintaining sample identity
• Ability to closely follow laboratory SOPs and appropriate laboratory safety protocols
• Proficiency with managing tabular data, for example in Microsoft Excel, including formulas and pivot tables
• Clear written and verbal communication, and the ability to work independently following training
Nice to Have:
• NGS library preparation experience
• Experience with column-based purification methods, PCR/qPCR, and/or nucleic acid extraction
• Familiarity with LIMS or other structured sample tracking systems
• Experience working under SOPs, in a regulated environment, or within a quality management system
• Basic data analysis skills
What We Offer:
• Competitive salary commensurate with experience
• Meaningful equity in an early-stage, venture-backed company
• Health, dental, and vision coverage
• Paid time off and company holidays
• A ground-floor role with direct impact on bringing cfRNA liquid biopsy into clinical diagnostics
