Position description
The Innovative Genomics Institute at the University of California, Berkeley seeks applications for a Junior/Assistant Specialist in the Ronda Lab, in the area of microbiome engineering
The Ronda Lab at the Innovative Genomics Institute (IGI), UC Berkeley, develops and deploys genome engineering and synthetic biology platforms to understand and reprogram microbial communities. Research in the lab centers on designing molecular tools for in situ microbiome editing, decoding host-microbiome molecular interactions, and translating these discoveries into next-generation biotechnology applications in health and agriculture.
This position supports a metabolic engineering project focused on the rumen microbiome and others human-related microbiomes. The Junior/Assistant Specialist will work at the intersection of anaerobic microbiology, metabolic engineering, and synthetic biology to develop and apply tools for engineering rumen microbial communities. The position will be embedded in the highly collaborative research environment of the IGI, with access to cutting-edge genomics and molecular biology facilities and expertise across UC Berkeley.
Applicants must be authorized to work in the United States at the time of hire. Visa sponsorship is not available for this position.
Responsibilities:
The position will contribute in three major ways: 1) metabolic and synthetic biology experiments targeting rumen microbial communities others human-related microbiomes, including anaerobic culturing, isolation and characterization of microbes, strain engineering, and microbial community manipulation; 2) molecular biology and genomics workflows, including plasmid design and construction, bacterial transformation or conjugation, PCR-based screening, Sanger and next-generation sequencing validation, and preparation of metagenomic sequencing libraries; and 3) data management and computational analysis, including processing and interpretation of metagenomic and amplicon sequencing datasets to characterize community composition and functional changes in engineered communities.
The position will maintain detailed records of all experiments, conclusions, and results through lab notebooks and internal data management systems. The Junior/Assistant Specialist will contribute to manuscript preparation, present findings at internal lab meetings and scientific conferences, and participate in the preparation of grant proposals. Opportunities to mentor undergraduate researchers and contribute to the collaborative culture of the Ronda Lab and the broader IGI community are expected.
Qualifications
Basic qualifications (required at time of application)
Bachelor's degree or equivalent international degree or enrolled in a bachelor's degree or equivalent international degree program.
Additional qualifications (required at time of start)
-Bachelor's degree or equivalent international degree.
Preferred qualifications

• Experience in strain/microbiome engineering, with particular interest in rumen microbial communities, anaerobic microbiology, microbial metabolism, and synthetic biology approaches for engineering bacterial functions.
• Experience with metabolic engineering, microbial pathway design, microbial community manipulation, or engineering microbes to alter metabolic outputs.
• Hands-on experience with molecular cloning, plasmid design and construction, bacterial culturing, anaerobic techniques, microbial transformation or conjugation, PCR-based screening, sequencing-based validation, and strain characterization.
• Experience working with complex microbial communities, microbiome samples, or non-model bacteria.
• Experience with next-generation sequencing workflows, metagenomics, microbiome data analysis, high-throughput screening, synthetic biology design tools, or computational analysis of microbial pathways.
• Demonstrated strong attention to detail, excellent organizational skills, careful record-keeping, and the ability to work effectively in a collaborative research environment.
• A strong interest in microbiome engineering, metabolic engineering, and translational synthetic biology.
