The Role:

We’re looking for a passionate and curious, Principal Scientist to join our team. If you’re excited by new challenges, solving complex problems, and learning every step of the way, you might just be the perfect fit. In this role, you’ll have the opportunity to drive impactful projects, collaborate with bright minds, and explore uncharted territories.

As a Principal Scientist at Just-Evotec, you'll have the freedom to ask the hard questions, think outside the box, and find creative solutions that push us forward. It’s a role where your curiosity will fuel both your personal growth and the success of the team.

What You’ll Do:

• Lead a diverse group of scientists responsible for development and tech transfer of early and late-stage (characterization and validation) upstream perfusion/intensified fed-batch processes for biotherapeutics manufacturing as well as technology development projects.  

• Serve as a Project Team Lead to execute client projects that involve multiple functional areas and the full range of regulatory stages. 

• Serve as an internal technical resource for cGMP manufacturing and Process Design as well as for external clients and partners for cell culture and bioreactor processes (small scale models, process transfer, and scale up) and author CMC regulatory sections. 

• Collaborate across the organization to accelerate clinical development timelines while reducing development costs. 

• Clearly and effectively communicate scientific information, experimental plans, and data to internal project teams, senior management, external clients, vendors, and technology development collaborators as well as the external scientific community such as regulatory agencies, review boards, and conferences. 

• Independently design, execute, and analyze statistically designed experiments (DOE). 

• Author SOPs, reports, and slides which summarize, organize, and interpret experiment results with review by appropriate team members.  

• Train, mentor, and supervise staff and interns. 

• Potential for weekend work (5-day work week/ 2 days off) and being on-call for critical bioreactor runs. 

• Other tasks as assigned.  

Who You Are:

• BS/MS in Engineering, Biochemistry, Biology, or related field with 12+ years of experience or Ph.D. in Engineering, Biochemistry, Biology, or related field with 8+ years of experience. 

• Expertise in bioreactor cell culture and perfusion technology development and tech as well ass CMC sections authoring for regulatory filings. 

• Experience with commercial process development, process characterization, and validation. 

• Expertise in design of experiments (DOE) and statistical analysis. 

• Experience with high throughput cell culture (e.g. HT assays, robotics such as Ambr systems, lab automation, or multi-omic data) is a plus. 

Additional Qualifications

• Experience analyzing data in tools such as JMP, R, or Python. 

• General understanding of cell biology, fluid dynamics, and biotransport as well as knowledge in other functional areas (downstream purification and analytical sciences). 

• General understanding of circuits (grounding, power, signal, etc.). 

• Experience working in a cGMP or clean room setting (this job is non-GMP but knowledge of GMP is helpful for process/tech transfer activities). 

 Why Join Us:

• Growth Opportunities: We’re a company that believes in continuous learning and development. Whether it’s professional courses, mentorship, or new projects, we’ll help you grow.

• Flexible Work Environment: We offer flexible work options to help you balance your professional and personal life, with hybrid work schedules in many of our various locations.
