Job Title: Scientist, Chemical Commercialization & Technical Operations  - PRO015711


Merck & Co., Inc. Kenilworth, N.J., U.S.A. known as Merck in the United States and Canada, is a global health care leader with a diversified portfolio of prescription medicines, vaccines and animal health products. The difference between potential and achievement lies in the spark that fuels innovation and inventiveness; this is the space where Merck has codified its legacy for over a century. Merck’s success is backed by ethical integrity, forward momentum, and an inspiring mission to achieve new milestones in global healthcare.

Merck Manufacturing Division, MMD, is a team of dedicated, energetic individuals who are committed to being the most trusted supplier of pharmaceuticals and health products worldwide. Our facilities, along with our external contractors, suppliers, and partners, comprise an interdependent global manufacturing network that’s committed to delivering a compliant, reliable supply to customers and patients on time, every time, across the globe. 


The Chemical Commercialization & Technical Operations department (CCTO) within the Merck Manufacturing Division (MMD) is seeking highly motivated individuals who are looking for an opportunity to work in a fast-paced job that provides a high degree of technical responsibility and leadership/growth opportunities at the interface between R&D and Manufacturing.  The Commercialization group within CCTO has three main functions: (i) laboratory and pilot-scale characterization of chemical processes for new Active Pharmaceutical Ingredients (API's), (ii) scale-up, technology transfer, and validation of API chemical processes in commercial manufacturing sites, and (iii)  technical support for existing in-line commercial products both in the laboratory and in the field. This Scientist, Engineering  (R2) position, leverages scientific knowledge and execution skills to (i) conducting and overseeing laboratory development, piloting, and scale-up / technology transfer, (ii) contributes actively to the cross-functional API working group (API-WG) discussion during process development, and (iii) provides technical support to both new and in-line commercial products both in the laboratory and with "boots-on-the-ground" in the field.


The incumbent is expected to provide and/or develop scientific expertise in API small molecule process characterization work by learning and utilizing QRM/QbD methodologies and tools around statistical design and analysis of experiments (e.g. DoE).  The candidate will also have the opportunity to manage development and validation activities at external suppliers largely remotely, with some limited travel expected. Support of research-led work is also possible to author regulatory filings with the FDA, etc. The role focuses on late-stage development, validation, and supply support. 




  • The position requires either a BS or MS in Chemical/Biochemical Engineering, Chemistry, or an appropriate related science from an accredited college/university.


  • Experience with product, process or equipment development or technical support for commercial products in any relevant industry (food, pharma/medical devices, diagnostics, cosmetics, chemicals, petroleum, etc.).
  • Strong understanding of the science behind chemistry and/or chemical engineering.
  • Desire to perform both laboratory experimentation and remote/field support of scale-up and manufacturing.
  • Ability to work in the laboratories at the Rahway, New Jersey, site with occasional domestic and international travel, if necessary.


  • Relevant work experience in Pharma process development in any modality (e.g. small molecules, large molecules, vaccines, drug substance or drug product, etc.) or chemical development in a related industry, ideally with experience conducting one or more programs of statistically-design experimentation.
  • Experience interfacing with internal and external partners executing manufacturing or development,
  • Familiarity with process scale-up, technology transfer, and boots-on-the-ground support while moving from laboratory to pilot plant/factory for new and existing products/processes.
  • Experience executing an experimental program or statistical data analysis to address issues of process design, robustness, or productivity for an existing product/process.
  • Familiarity with the concepts and application of GLP’s/cGMP’s ideally during Pharma drug substance / drug product development and production, e.g. in a pilot and/or factory setting.


Your role at Merck is integral to helping the world meet new breakthroughs that affect generations to come, and we’re counting on your skills and inventiveness to help make meaningful contributions to global medical advancement. At Merck, we’re inventing for life.
