Full Job Description

BlueNalu, Inc. is a fast-growing, San Diego-based company that is pioneering the production of seafood products derived directly from fish cells. Using proprietary cell biology techniques and engineering processes, BlueNalu’s platform technology can produce a wide array of value-added seafood products, that are healthy for people, humane for animals, and sustainable for the planet. Our products will contain no mercury, microplastics or other contaminants.

Job Summary:

The core responsibility of this position is to develop and optimize scalable separation technologies that will be critical for seafood cell culture. This role will specifically focus on understanding the key technologies for solid-liquid (such as cells from the culture) and liquid-liquid separations in cell culture and to effectively scale these technologies towards manufacturing. Candidates should have expertise in various separation technologies used in cell culture and demonstrated expertise in scaling up separation technologies, equipment design, experimental design, problem solving, statistical analysis, and communication of results. This position will require significant subject matter expertise and hands-on laboratory work. This position reports directly to the Sr. Bioprocess Engineer.

Essential Responsibilities:

· Lead evaluation of novel and existing technologies followed by optimization, scale-up and demonstration of solid-liquid and liquid-liquid separations for seafood cell culture to meet cost and performance criteria for manufacturing.

· Independently operate bench-scale and pilot-scale separations equipment downstream to seafood cell culture; and troubleshoot and maintain the equipment for continued operation to facilitate bioprocess development and scale-up.

· Develop specifications, procedures, and testing protocols as required for bioprocess development and validation.

· Work cross-functionally with R&D, Engineering, Quality, and Manufacturing to successfully transfer SOPs and formulations that meet target specifications.

· Collaborate with suppliers and vendors to effectively source materials and services.

· Provide regular updates to the project team and management on project timelines and deliverables.

· Preparation of invention disclosures and other IP documentation as required.

· Some weekend work may be required.
