Scientist, Chemical Commercialization & Technical Operations:

Rahway New Jersey
Requisition ID: PRO016675

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 Technology (CCT) department 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, mentoring, and leadership of internal and external work. This Scientist, Engineering (R2) leverages scientific and technical experience to: 

  • complete assigned late-stage API characterization projects
  • mentor junior staff within the CCT organization
  • embed World-Class Supply (WCS) needs in the API working group (API-WG) discussions during process development
  • lead or support internal and external development, pre-validation, and validation for a selection of portfolio projects

 The incumbent is expected to provide and/or develop scientific expertise in small molecule process characterization work by learning and utilizing QRM/QbD methodologies and tools around statistical design and analysis of experiments. Face-to-face mentoring is expected within laboratories at the Rahway, NJ site to develop junior staff. The role includes participation in one or more cross-divisional API working groups (API-WG) and the candidate will need to help influence the API-WG’s direction on Merck Manufacturing Division (MMD) specific needs. The candidate will also have the opportunity to manage development and validation activities at external suppliers largely remotely, with some travel expected (10 – 20%). Normal travel per campaign might include a kickoff trip and a separate multi-week period of on-site coverage, typically 1-3 times per year depending on steps and complexity. Support of Merck Research Laboratories (MRL) led filing work, early development work, and/or piloting is also likely. The role focuses on late-stage development, validation, and supply support. As the early-stage portfolio progresses to late-stage projects, the incumbent is expected to help drive current MRL-led characterization work more fully to CCT ownership, leadership and execution/management.
