• Identify, evaluate, and quantify critical fermentation and downstream process parameters using data-driven experimentation, design of experiments, and statistical process control methodologies.
• Develop, optimize, and scale fermentation processes to support registration studies, field trials, and commercialization.
• Independently coordinate and execute internal and external production activities to generate materials for bioassays, greenhouse studies, field trials, and other development programs.
• Analyze experimental data, present scientific findings in cross-functional team meetings, and prepare clear protocols, technical reports, and development documentation.
• Identify, evaluate, and engage third-party service providers, technologies, and manufacturing partners that can accelerate the development and commercialization of Invaio’s technologies.
• Make key inventive contributions to Invaio’s growing intellectual property portfolio.
• Provide scientific and operational leadership across cross-functional projects and programs, ensuring alignment, effective execution, and timely delivery.
• Contribute to a dynamic and collaborative culture that values teamwork, innovation, scientific rigor, and professional development.
• Ability to travel >50% as needed to support tech transfer and commercialization efforts at third party manufacturing partner sites
