Brisbane, CA, USA
Posted on Friday, April 29, 2022
Mammoth is hiring a Senior Scientist I to contribute to R&D projects run within the Platform team. The Platform team develops next-generation CRISPR tools for therapeutic genome editing applications and is composed of technical staff with diverse strengths in bioinformatics, biochemistry, protein engineering and high-throughput screening. The successful candidate will work on CRISPR tool development projects during their early (proof-of-concept) and/or late (optimization) phases. This is a fantastic opportunity to impact human health by making CRISPR tools that cure genetic disease.


  • Plan, design and execute experiments for CRISPR tool development projects
  • Design and produce DNA and cell-based reagents for genome editing experiments
  • Contribute creatively to seed innovation projects and shape execution tactics
  • Document experiments in electronic laboratory notebooks
  • Present experimental results at internal meetings
  • Disclose inventions to the IP team for patenting
  • Other duties as assigned


  • PhD in Molecular Biology, Biochemistry, Biomolecular Engineering or a related discipline with 3 years relevant professional experience in industry or academia, following completion of PhD. For non-PhD candidates with a Bachelor's degree, 6 additional years of professional experience are required
  • Hands-on experience in three of the following areas: (i) bioinformatic approaches for novel protein discovery, (ii) automated methods for high throughput molecular biology workflows, (iii) biochemical assay of nucleic acid-modifying enzymes, (iv) directed evolution approaches for protein engineering, (v) plasmid design for bacterial and mammalian expression of recombinant proteins and RNAs, (vi) next-generation sequencing (NGS) assay design and library preparation


  • 2 years biotechnology industry experience
  • 2 years experience developing CRISPR tools for genome editing applications
  • Computer and scripting skills (Benchling, Geneious, JMP, SQL, R, Python)


  • Company-paid health/vision/dental benefits
  • Unlimited vacation and generous sick time
  • Company-sponsored meals and snacks
  • Wellness, caregiver and ergonomics, mental health and education benefits
