In the posting’s own words

We are hiring Research Associates: early-career bench scientists who will join a small team to help establish our biology research program. This is an entry-level role, great for individuals who have done some research during an undergrad or masters program and may be considering pursuing a PhD in Life Sciences in the future.

What it asks for · 8

  • Have hands-on research experience in molecular biology, biochemistry, or a closely related field
  • Are proficient with foundational molecular biology techniques: PCR, gel electrophoresis, molecular cloning, and plasmid preparation
  • Have experience with aseptic technique and bacterial or mammalian cell culture, and with nucleic acid extraction, purification, and quantification
  • Follow, document, and adapt experimental protocols with care and precision
  • Are highly motivated, eager to learn, and energized by hands-on bench work
  • Are practical and resourceful — you'd rather find a way through than a reason it can't be done
  • Listen carefully, take feedback well, ask good questions, and are comfortable when priorities shift quickly
  • Are excited to use AI models as a tool at the bench to plan experiments, interpret data, and decide what to try next

Also a plus

  • A BS or MS in molecular biology, biochemistry, chemical biology, microbiology, bioengineering, or a related discipline
  • Protein expression and purification experience (e.g., affinity, SEC, IEX)
  • Mammalian cell culture experience, including transfection and stable line maintenance
  • Enzyme kinetics or quantitative biochemical assay development (fluorescence, absorbance, FRET)
  • Next-generation sequencing library preparation experience
  • Familiarity with common bioinformatics workflows and molecular biology software (e.g., sequence analysis, alignment, primer and construct design)
  • Experience using AI tools such as Claude in a research setting — for literature review, protocol drafting, data interpretation, or experimental troubleshooting

What the job covers

  • Execute molecular biology and biochemistry experiments at the bench under the direction of senior scientists
  • Maintain meticulous, reproducible records and contribute to shared protocols
  • Troubleshoot experiments, propose adjustments, and present results clearly in group meetings
  • Maintain mammalian and bacterial cell lines, materials stocks, and reagent inventories
  • Learn and adopt new techniques rapidly as projects evolve, with training provided

How this page was made

An automated read of a public job posting, fetched November 2, 2026 and last changed by Anthropic on October 22, 2026. Every list above is pulled from the posting’s own sentences — nothing rewritten, nothing added, no judgment about the role or the company. Counts and seniority are read off the text by rule, so they can be wrong where the posting is unusual. The original is the only thing that binds. Openings close without warning; check the source before spending an evening on it.
