What does a senior scientist in downstream process development do?

A Senior Scientist in Downstream Process Development focuses on developing, optimizing, and scaling up processes to purify biological products such as proteins or antibodies after cell culture (the 'downstream' part of biomanufacturing). They design experiments, analyze data, and work with cross-functional teams to ensure product quality and regulatory compliance. Their role is critical in moving biopharmaceutical products from research to commercial production by ensuring efficient and robust purification processes.

What are the key skills and qualifications needed to thrive as a senior scientist in downstream process development?

To thrive as a Senior Scientist in Downstream Process Development, you need advanced knowledge in bioprocess engineering, protein purification, and process scale-up, typically supported by a Ph.D. or Master’s degree in a relevant field. Expertise with chromatography systems (such as AKTA), analytical instrumentation, and familiarity with regulatory requirements like GMP are essential. Strong problem-solving abilities, leadership, and effective communication skills distinguish top performers in this role. These competencies are crucial for developing robust, scalable processes that meet quality standards and drive successful product development.

What are some common challenges faced by senior scientists in downstream process development, and how can they be addressed?

Senior Scientists in Downstream Process Development often encounter challenges such as optimizing purification processes for novel biologics, scaling up from lab to production scale, and ensuring product consistency and regulatory compliance. Addressing these challenges typically involves close collaboration with cross-functional teams, continuous process optimization, and staying current with industry advancements in chromatography and filtration technologies. Proactive problem-solving, effective communication, and leveraging data analytics are also key strategies for overcoming obstacles in this role.

Who We Are

We are the first publicly-traded biotech or pharmaceutical company to take the form of a public benefit corporation. Our public benefit purpose is to provide a brighter future for patients through the development of novel pharmaceutical therapies; and technologies that expand the availability of transplantable organs. United Therapeutics (Nasdaq: UTHR) seeks to travel down the corridors of indifference to develop treatments for rare, deadly diseases. We were founded in 1996 by a family seeking a cure for their daughter’s pulmonary arterial hypertension (PAH). Today, we have six FDA‑approved therapies that treat PAH, pulmonary hypertension associated with interstitial lung disease (PH‑ILD) and neuroblastoma, a rare pediatric cancer. Our near‑term pipeline seeks to develop additional therapies for PAH and pulmonary fibrosis (PF). The cure for end‑stage life‑threatening diseases like PAH, PH‑ILD, PF, and many others is an organ transplant, but only a small percentage of donated organs are available to address the vast need. For this reason, we are working to create manufactured organs to address the shortage of kidneys, hearts, lungs, and livers available for transplant. We believe an unlimited supply of tolerable, transplantable organs will eliminate the transplant waiting list and cure end‑stage organ diseases for which transplant is not currently an option.

Who You Are

At Thymmune, you'll join a team pushing the boundaries of cell therapy and transplant innovation through advanced iPSC‑derived manufacturing technologies. As a Senior Scientist, Process Development, you'll play a pivotal role in designing and optimizing processes that support the development of transformative therapies, helping move breakthrough science from concept to clinic. It's an opportunity to solve tough scientific challenges, collaborate with world‑class colleagues, and contribute to a future where more patients have access to life‑changing treatments.

  • Design, lead, and optimize iPSC expansion, differentiation, and scale‑up processes to improve process robustness, reproducibility, and product quality
  • Design and execute development strategies for harvest, downstream processing, formulation, fill‑finish, and fresh/cryopreservation processes to support clinical and commercial manufacturing needs
  • Lead process characterization studies and author technical documentation to support technology transfer, process validation, and GMP manufacturing readiness
  • Collaborate cross‑functionally with Analytical Development and other technical teams to define critical process attributes, characterize process performance, and advance process understanding
  • Design and conduct complex studies to develop and optimize biomaterial‑based cell delivery approaches, formulation strategies, and clinical in‑use hold times
  • Contribute substantively to FDA and other regulatory submissions by authoring and reviewing technical reports, process development summaries, protocols, risk assessments, and CMC documentation supporting product development and clinical advancement
  • Analyze, interpret, and communicate experimental results to project teams and leadership, providing scientific recommendations that support program objectives and development decisions
  • Evaluate emerging scientific literature, technologies, and industry trends to identify opportunities for innovation and continuous improvement within the process development function
  • Maintain accurate and compliant experimental records and provide scientific guidance, technical expertise, and mentorship to junior scientists and research associates
  • Perform all other duties as assigned
Minimum Requirements
  • A Bachelors Degree with 10 years of relevant experience in cell biology, developmental biology, tissue engineering, biomaterials, biomedical engineering or related field
  • OR a Masters degree with 10 years of relevant experience in in cell biology, developmental biology, tissue engineering, biomaterials, biomedical engineering or related field
  • OR a PHD with 5 years relevant experience in in cell biology, developmental biology, tissue engineering, biomaterials, biomedical engineering or related field
  • 5+ years of biotech/pharma industry experience
  • Technical expertise in iPS expansion and differentiation process development
  • Technical expertise in downstream processing, formulation and stability of cell based products including fresh and cryo formulation development
  • Experience with laboratory instrumentation and data software; with appropriate word processing, spreadsheet, presentation and related standard software
  • Experience supporting FDA and/or other regulatory submissions through preparation of technical reports and CMC documentation
  • Ability to mentor junior scientists and research associates and provide scientific guidance across projects
  • Ability to design and perform complex and technically challenging experiments
  • Excellent written, verbal communication and presentation skills
Preferred Qualifications
  • Doctor of Philosophy (PhD) or a Master’s Degree in biology, cell biology, biomedical engineering, tissue engineering, developmental biology, or related scientific discipline
