Merck & Co, Inc

Associate Principal Scientist, Drug Delivery Device and Combination Product Characterization and Design

Aerospace and Aviation

Design Engineer


Rahway, New Jersey, United States

Job Description

Our Development team ensure production can be scaled up whilst remaining stable, effective, deliverable and safe. Following formulation, cutting edge computer modelling techniques are used to simulate outcomes and, if successful, PKPD and toxicity studies bring the science one step closer to giving hope to patients.

The Device Development (DD) Team is seeking a hands-on analytical characterization and design focused engineer. This position will be responsible for technical interrogation of the various drug delivery device technology platforms supporting our Company’s pipeline to identify risks (i.e. when/how will the device fail?) and opportunities for improvement. They will utilize a wide variety of cutting-edge analytical instruments and methods, including in silico modeling, to build fundamental understanding of the devices’ material and functional properties and attributes. This understanding, combined with extensive data analysis/interpretation, will allow the role to design and develop functional improvements for these platforms and, as the opportunities arise, develop new and novel delivery technologies.

These drug delivery device technology platforms are often assemblages of injection molded plastic components driving delivery of a drug, typically though mechanical (i.e. compress/torsion spring, compressed gas) or electro-mechanical (i.e. DC motor and battery driving a gearbox) means. Examples include, but not limited to, injector pens and inhalers. At this early stage of evaluation material is often limited and will demand creative approaches. Additionally, this position will leverage design and prototyping skills to ideate, breadboard, and reduce to proactive novel drug delivery device concepts.

Education Requirement (minimum):

  • B.S., M.S or Ph.D.. in Mechanical Engineering or equivalent field is required.

Required Experience and Skills:

  • A minimum of 4 years with Ph.D. (minimum 10 years with B.S.) of design, engineering, and testing experience.

  • Solid testing and troubleshooting skills able to work independently in a laboratory setting.

  • Experience with mechanical testing, imaging, and measurement equipment and techniques. Including, but not limited to, tensile/compression testing, surface characterization, x-ray computed tomography, rheometry, and microscopy.

  • Excellent collaboration, ideation, and prototyping skills, including facilitating design brainstorming sessions, developing proof of concepts, working prototypes and conducting functional testing.

  • Experience in 3D CAD (e.g. Solidworks), geometric tolerancing and stack-up analysis.

  • Fluency in finite element analysis (FEA) and computational fluid dynamics (CFD).

  • Fluency in Design Failure Modes and Effect Analysis (FMEA, DFMEA).

  • Cross-functional communication – communicating complex mechanical engineering information in layman’s terms to facilitate cross-functional understanding.

  • Development experience in risk-oriented, regulated environments.

  • Development project leadership with a proven track record collaborating with and managing external vendors/manufacturers.

Preferred Experience and Skills:

  • Experience with medical device development with understanding of Design Controls (21 CFR 820.30).

  • Familiarity with the following standards: Quality Management – ISO 13485, Risk Management – ISO 14971, EU Medical Device requirements – Council Directive, 93/42/EEC, Medical Electrical Equipment – EN 60601, Medical Device Software Standard – IEC 62304, ISO 11608 Needle-based injection system for medical use
