Scientist – Protein Engineering

Location: San Diego, CA
Position Type: Full-Time
Salary Range: $110,000 - $128,000
Area(s) of Expertise Desired: Biochemistry, Enzymology, Protein Engineering and Evolution, Molecular Biology, Gene Editing
Job Code: MD2319


Cibus is a biotechnology company with advanced technologies to precisely target and direct a plant’s natural gene-editing processes. This approach accelerates natural plant breeding that has been a staple of farming for thousands of years and has resulted in a rapid, versatile and low-cost way to produce sustainable industrial and agricultural products and improve human health by safely harnessing nature's own genetic diversity.

The company has a worldwide presence, with subsidiaries in Europe and North America and a state-of-the-art research and development center in San Diego. Cibus has a pipeline of traits for canola and rice and is developing crop platforms and a pipeline of trait products in other major global crops including soybean, corn, and wheat. The broad applicability of Cibus’ technologies is highlighted by the company’s strain-advancement program, which develops sustainable products in microbial platforms for the food, flavor and fragrance, and personal care markets.

Cibus has an immediate opening for a Scientist – Protein Engineering who will help us to revolutionize plant breeding using our unique, gene editing technology. This position will drive in the lab efforts for an exciting new project that will greatly improve global agricultural sustainability. The successful applicant will have deep expertise using microbial and in vitro systems to build assays to monitor and evolve enzyme activities. A demonstrated ability to leverage computational approaches and collaborate across functional teams is essential. This position offers an exciting opportunity for a motivated individual to grow and influence in a dynamic company focused on cutting edge gene editing technology.

Role Responsibilities:

  • Be part of a talented team of scientists who use cutting edge protein and enzyme engineering technologies to identify new gene editing targets for next-generation crop traits involved in weed control, disease resistance, nitrogen use, and oil quality.
  • Lead and execute laboratory experiments to build new enzyme assays and use directed and random approaches to evolve catalytic activities.
  • Integrate with the Computational Biology team to predict new target opportunities and jump start in the lab efforts.
  • Identify and implement opportunities to grow the technology platform.
  • Collaborate with Technology Development, Crop, and Production teams to transfer new targets into the gene editing pipeline.
  • Provide subject matter and scientific expertise across the company.
  • Mentor/supervise junior team members and help to grow a rapidly expanding team.


  • Ph.D. degree in a Biological or Engineering Science with 2+ years of experience working in a protein engineering or similar environment. Post-doctoral work may serve as experience.
  • Deep expertise with protein engineering, enzyme evolution and molecular biology technologies. Strong understanding of fatty acid synthesis and metabolism. An understanding of gene editing technology is also desired.
  • An expert at developing new enzyme assays using microbial and in vitro recombinant systems. Strong experience building variant libraries with directed and random approaches and screening those libraires for new and modified catalytic activities.
  • Demonstrated ability to leverage computational and structural biology prediction to evolve protein activity.
  • Practical experience implementing automation approaches to improve assay throughput and reliability is beneficial.
  • Proactive communicator with demonstrated success using oral and written strategies to communicate project status and direction.
  • Leads by example, using positive strategies to help establish a professional environment of trust, respect, and collaboration. Demonstrated ability to positively influence others with strong capabilities to mentor and supervise junior scientists.
  • A strong collaborator capable of driving success in a highly matrixed work environment.
  • Prior experience working in an agricultural biotech and/or plant biology environment is beneficial, but not required.

Cibus provides an attractive compensation and benefits package that includes medical/dental/vision, flexible spending, 401(k) plan, vacation and sick leave.
