How to Get into Medical Affairs

There's no single pathway into medical affairs jobs. Most people get there from one of two backgrounds – a scientific or clinical career, or clinical research – and each route gets you there in a different way.

What's consistent across both is that it's competitive to break in, particularly at MSL level, where a lot of entry-level postings still ask for prior MSL experience.

If you're working out how to get into medical affairs yourself, knowing which route fits your background – and what the path looks like once you're through the door – makes it easier to plan the move deliberately rather than apply broadly and see what happens.

Main Pathways Into Medical Affairs Jobs



Coming From a Scientific or Clinical Background

This is the classic entry point, and it's still the one most companies lean towards for medical affairs jobs at entry level. PhD graduates, postdocs, pharmacists, and the occasional doctor move into a medical science liaison role without having worked in industry before.

Most MSL roles ask for an advanced scientific degree – a PhD, Pharmacology, or MD – and big pharma companies in particular tend to hold that line. Biotech and smaller companies are sometimes more flexible, and will consider a master's degree paired with strong therapeutic-area experience. Either way, tailoring your application to a specific therapeutic area close to your own research background tends to carry more weight than a broad, generalist CV.

Coming From Clinical Research

Clinical research associates and other trial-based roles are another established route in, particularly into medical affairs scientist positions, which sit closer to evidence generation and publication work than field-based liaison roles. For people who've already spent years close to trial data, this tends to be a sideways move rather than a leap into something unfamiliar.

How the Medical Affairs Career Path Progresses

Medical affairs careers tend to follow a fairly consistent structure once you're in, though the exact steps and titles vary by company size and therapeutic area. Most people start in medical information or as an MSL, move to senior MSL once they've built a track record with key opinion leaders, and from there the path typically splits into a medical advisor or medical manager role.

From medical manager, the usual next step is medical director, overseeing a therapeutic area or business unit. Beyond that sits country or regional medical director, and eventually global medical affairs leadership for people who stay in the field long enough to get there.

It isn't the only shape a medical affairs career can take. Some people move sideways into medical affairs scientist roles that stay closer to research. Others move out towards regulatory affairs or brand management once they've built enough internal credibility to make that jump. None of these are dead ends – they're different uses of the same foundation.

What Can Help You Progress in Medical Affairs Jobs

A handful of things separate the people who land their first medical affairs role from those who keep applying without much luck.

Having the right qualification for the door you're knocking on matters most. Big pharma companies still tend to want a science related degree with postgrad qualifications for MSL roles, while biotech and smaller companies are often more open to a master's degree combined with solid clinical or research experience.

A tightly focused CV helps just as much as the degree itself. If your background is in oncology, apply for oncology roles and make sure your CV reads that way from the first line. Hiring managers in medical affairs are generally looking for depth in a therapeutic area, not breadth across several.

Mentorship and a genuine network inside the industry make a real difference too, especially for people coming from academia who haven't had to interview for an industry role before. Talking to people already working as MSLs, even informally, helps close the gap between understanding the science and understanding how the job itself actually runs day to day.
