MSD

MSD runs its student programs on two tracks, feeding seven functions that include R&D, Engineering & Manufacturing, Finance, IT and Supply Chain:

• Internships: 9-12 weeks, June to August, exact timing dependent on country
• Co-ops: 4-6 months, offered year-round
• Manufacturing Leadership Development Program (MLDP): a graduate rotation of at least two technically focused roles in operations, technical operations or quality, with three-tier mentoring and potential for a one-year international assignment
• IT Emerging Talent Rotation Program: a parallel graduate rotation across three information-technology groups

A co-op is a semester-plus commitment most students can only make once during a degree, and the MLDP resolves over multiple rotations rather than a single hiring decision, so choosing among internship, co-op and the graduate rotation programs is really a choice about how much of a degree timeline, or how many years post-graduation, a candidate can commit before applying.

MSD's parent, Merck & Co., placed No. 68 on Fortune's 100 Best Companies to Work For in 2025 (Great Place to Work). MSD also runs one of the industry's largest dedicated Animal Health divisions, which generated $5.877 billion in 2024 revenue, the second-highest of any animal health company globally (PharmaShots).

For an early-career applicant with a veterinary or animal-science background, Animal Health is a distinct entry track that most large human-health-focused pharma employers do not run at comparable scale, worth weighing alongside the standard R&D and manufacturing tracks rather than treated as a side function.
