MSL Job Guide: How to Land a Medical Science Liaison Role in 2025
14 Oct, 2023
If you've ever picked up a prescription from the pharmacy or watched a loved one recover thanks to a life-saving drug, you've probably wondered: what job makes medicine? It's a question I hear surprisingly often from aspiring healthcare professionals, and the answer is far more layered than most people realize. There isn't just one role responsible for getting medications from a laboratory concept to your medicine cabinet — there's an entire ecosystem of careers dedicated to researching, developing, manufacturing, testing, and distributing the medicines we all depend on. At healthcareers.app, we've helped thousands of job seekers navigate the complex world of healthcare employment, and today I want to walk you through every career path connected to making medicine, along with related healthcare roles you might not have considered.
When people ask what job makes medicine, they're usually thinking of pharmacists — and that's a great starting point. But the truth is that dozens of specialized professionals contribute to the creation, quality assurance, and delivery of pharmaceuticals. Let me break down the key roles across the entire medicine-making pipeline.
The journey of every medicine begins in a research laboratory. Pharmaceutical scientists are the professionals who discover and design new drug compounds. They work at the intersection of chemistry, biology, and medicine to identify molecules that could treat or cure diseases. These scientists typically hold a Ph.D. in pharmaceutical sciences, medicinal chemistry, pharmacology, or a related discipline.
According to the Bureau of Labor Statistics (bls.gov), medical scientists — a category that includes pharmaceutical researchers — earned a median annual wage of $99,930 as of May 2023, with employment projected to grow 10% from 2022 to 2032, faster than the average for all occupations. This growth reflects the ongoing demand for new therapies, especially in oncology, immunology, and rare diseases.
Once a promising compound is identified, pharmacologists study how it interacts with biological systems. They determine dosage ranges, identify side effects, and evaluate how the body absorbs, distributes, metabolizes, and excretes the drug. Toxicologists work alongside them to ensure that a drug candidate won't cause unacceptable harm. Both roles are essential to the preclinical phase of drug development, and they typically require advanced degrees — often a Ph.D. or an M.D. with specialized training.
Here's where the medicine literally gets made. Pharmaceutical manufacturing technicians operate the equipment that produces tablets, capsules, injectables, and other dosage forms at scale. They follow strict Good Manufacturing Practices (GMP) regulated by the FDA to ensure every batch meets rigorous quality standards. Chemical engineers and process engineers design and optimize the manufacturing processes themselves.
These roles are incredibly important and often don't require a Ph.D. Many pharmaceutical manufacturing technicians enter the field with an associate's degree or a bachelor's degree in chemistry, biology, or a related science, making this one of the most accessible entry points for people who want to be directly involved in making medicine.
While pharmacists don't typically manufacture drugs from scratch, they play a critical role in the final preparation and delivery of medicine to patients. Compounding pharmacists, in particular, do make customized medications by mixing ingredients to create formulations tailored to individual patient needs — for instance, creating a liquid version of a drug that's normally only available as a pill for a patient who has difficulty swallowing.
To become a pharmacist, you need a Doctor of Pharmacy (Pharm.D.) degree, which typically takes four years of professional study after completing prerequisite undergraduate coursework. Pharmacy technicians, who assist pharmacists, usually need a high school diploma and on-the-job training, though certification can improve job prospects. According to the Bureau of Labor Statistics, pharmacists earned a median annual wage of $136,030 in 2023.
Quality control (QC) analysts test raw materials, in-process samples, and finished products to verify that medicines meet all specifications. Quality assurance (QA) specialists focus on the systems and processes that ensure consistent quality throughout manufacturing. These professionals are the gatekeepers who prevent contaminated, improperly dosed, or otherwise unsafe products from reaching patients. A bachelor's degree in chemistry, biology, or a related field is typically required, with some positions requiring a master's degree or relevant certifications.
Before any medicine can be sold, it must receive approval from regulatory bodies like the U.S. Food and Drug Administration (FDA). Regulatory affairs specialists prepare and manage the massive documentation packages required for drug approval. They ensure that clinical trial data, manufacturing processes, and labeling all comply with federal regulations. This is a field where attention to detail is paramount, and professionals often hold degrees in life sciences, pharmacy, or regulatory science.
Making medicine is only half the story. A separate but equally vital set of healthcare professionals ensures that the right medicines reach the right patients at the right time.
Doctors and advanced practice nurses are the primary prescribers of medication. They diagnose conditions, select appropriate therapies, monitor patient responses, and adjust treatment plans. Their deep clinical knowledge is essential to the safe and effective use of every medicine that's manufactured.
Before a medicine reaches the market, it must be tested in human clinical trials. Clinical research coordinators (CRCs) manage the day-to-day operations of these trials at research sites, while clinical research associates (CRAs) monitor trials across multiple sites to ensure data integrity and regulatory compliance. These roles are excellent entry points into the pharmaceutical industry for candidates with a bachelor's degree in a health-related field.
I find that many people who ask about medicine-making careers are actually exploring the broader healthcare landscape. Let me highlight two related career paths that come up frequently on our platform.
One of the most common questions I see from career changers on healthcareers.app is what education is required to be an occupational therapist. Occupational therapists (OTs) help patients develop, recover, and maintain the skills needed for daily living and working after illness, injury, or disability. While OTs don't make medicine, they often work closely with pharmacological treatments as part of a patient's comprehensive care plan.
To become an occupational therapist, you need a master's degree in occupational therapy at minimum, though many programs now offer an entry-level doctoral degree (OTD). You must also pass the National Board for Certification in Occupational Therapy (NBCOT) exam and obtain a state license. According to the Bureau of Labor Statistics, occupational therapists earned a median annual wage of $96,370 in 2023, and the field is projected to grow 12% from 2022 to 2032 — significantly faster than average. Prerequisites typically include coursework in anatomy, physiology, psychology, and biology, so if you have a science background, this could be a natural fit.
Another area I want to address is jobs in the vet field, because the process of making medicine for animals closely parallels human pharmaceutical development — and many professionals work across both sectors. Veterinary pharmacologists develop drugs specifically for animal use, while veterinary pharmaceutical companies manufacture everything from livestock antibiotics to pet cancer treatments.
Here are some popular jobs in the vet field that intersect with medicine:
The National Institutes of Health (nih.gov) highlights the concept of "One Health," which recognizes that human, animal, and environmental health are deeply interconnected. This means that professionals working in the vet field often contribute directly to advances in human medicine as well, making this a uniquely rewarding career path.
If you're inspired to pursue a career that involves making medicine, here's a practical roadmap I recommend based on my experience helping healthcare job seekers on our platform:
Compensation varies widely depending on the specific role, education level, and experience. Here's a general overview based on data from the Bureau of Labor Statistics and industry reports:
These figures can increase substantially with experience, advanced certifications, and leadership responsibilities. The pharmaceutical industry is also known for offering competitive benefits packages, including tuition reimbursement and research funding.
Pharmaceutical manufacturing technicians and chemical engineers are the primary professionals who produce medicine in factory settings. They operate specialized equipment, follow FDA-regulated Good Manufacturing Practices, and ensure every batch of medication meets strict quality and safety standards. Entry-level technician roles typically require an associate's or bachelor's degree in a science-related field.
While most roles in pharmaceutical development require at least a bachelor's degree, some entry-level production and packaging positions in pharmaceutical manufacturing facilities accept candidates with a high school diploma and provide on-the-job training. Pharmacy technician roles also typically require only a high school diploma, though certification is increasingly preferred by employers.
A pharmacist is a licensed healthcare professional who dispenses medications, counsels patients, and in some cases compounds custom formulations. They hold a Doctor of Pharmacy (Pharm.D.) degree. A pharmaceutical scientist works in research and development to discover, design, and test new drugs. They typically hold a Ph.D. in pharmaceutical sciences or a related discipline. Both are essential to the medicine pipeline, but they work at very different stages.
To become an occupational therapist, you need at minimum a master's degree in occupational therapy from an accredited program, though entry-level doctoral programs (OTD) are becoming more common. You must also pass the NBCOT certification exam and obtain state licensure. Prerequisite coursework typically includes anatomy, physiology, psychology, and statistics.
Absolutely. Jobs in the vet field that involve medicine include veterinarians who prescribe and administer animal medications, veterinary pharmacologists who develop drugs for animal use, and veterinary technicians who assist with medication administration. Veterinary pharmaceutical companies also employ research scientists, quality control specialists, and regulatory affairs professionals — many of the same roles found in human pharmaceutical companies.
So, what job makes medicine? The honest answer is that it takes an entire team of dedicated professionals — from research scientists who discover new compounds, to manufacturing technicians who produce them at scale, to pharmacists who prepare and dispense them, to physicians who prescribe them. Each link in this chain is essential, and each represents a meaningful career opportunity for someone passionate about improving human (and animal) health.
