• Comply with laboratory safety and data-integrity requirements.
Skills
• Strong experimental design, analytical thinking, and problem-solving skills.
• Proficiency in mammalian cell culture and molecular biology techniques (e.g. aseptic technique, cell transfection, DNA/RNA extraction, PCR, qPCR, electrophoresis, molecular cloning, DNA/RNA sequencing, immunoblotting, FACS, microscopy).
• Familiarity with multi-omics study design, bioinformatics, statistical analysis, and systems biology.
• Strong understanding of molecular cell biology fundamentals including DNA replication, transcription, translation, proteostasis, metabolism, cellular stress mechanisms, and their relation to recombinant protein production.
• Effective written and verbal communication.
• Ability to work well and collaboratively within multidisciplinary teams.
• Strong attention to experimental rigor, documentation, reproducibility, and scientific integrity.
Education/Experience
• Bachelor’s or Master’s degree in molecular biology, cell biology, biochemistry, biotechnology, bioengineering, systems biology, or a related field required.
