Onsite, San Carlos, CA

$40-45/hr

About the Opportunity

We’re seeking a detail-oriented, hands-on Laboratory Associate to support reagent preparation, inventory management, and high-throughput screening operations in a fast-paced biotechnology environment.

In this role, you’ll work closely with assay development and screening scientists to ensure critical laboratory materials are accurately prepared, organized, documented, and ready for experimentation. This is an excellent opportunity for someone with a background in biology, biochemistry, or a related field who enjoys hands-on laboratory work, thrives in an organized environment, and takes pride in precision and accuracy.

What You'll Do

• Receive, label, organize, and maintain inventory of laboratory reagents, including antibodies, buffers, and other materials used in assay development and screening.
• Track reagent quantities, lot numbers, concentrations, storage locations, and expiration dates to ensure accurate inventory records.
• Monitor inventory levels, identify potential shortages, and coordinate replenishment to support uninterrupted laboratory operations.
• Prepare antibody formulations, buffers, dilutions, and other reagents for high-throughput screening campaigns using established laboratory protocols.
• Perform accurate pipetting and solution preparation while maintaining consistency across high-volume workflows.
• Document reagent preparation, lot usage, and sample-to-plate mapping to ensure complete traceability throughout screening experiments.
• Collaborate with scientists to anticipate reagent needs and prepare materials ahead of scheduled experiments.
• Maintain a clean, organized, and safe laboratory environment while following good laboratory practices and documentation standards.

What We're Looking For

• Bachelor's or Master's degree in Biology, Biochemistry, Molecular Biology, Bioengineering, or a related scientific discipline.
• 1–3 years of hands-on laboratory experience in a biotechnology, pharmaceutical, or academic research environment.
• Strong pipetting skills, including experience with multichannel pipettes.
• Familiarity with antibodies, including proper handling, storage, dilution, and common antibody formats.
• Experience preparing laboratory buffers, solutions, and reagents, with proficiency in dilution and concentration calculations.
• Strong Excel skills, including sorting, lookups, and basic formulas for organizing and tracking laboratory data.
• Excellent organizational skills, attention to detail, and ability to maintain accurate laboratory documentation.
• Ability to manage repetitive, high-volume laboratory tasks while consistently maintaining quality and accuracy.
• Comfortable using AI assistants, such as Claude, to support documentation, data organization, and workflow efficiency.

Nice to Have

• Experience supporting high-throughput screening or assay development workflows.
• Familiarity with automated liquid handling instruments.
• Experience using Laboratory Information Management Systems (LIMS) or electronic laboratory notebooks (ELNs).
