Medical affairs is one of the fastest-growing functions in the pharmaceutical and biotech industry, and it’s a common destination for clinicians, pharmacists, and researchers looking to move beyond direct patient care. Breaking in requires a combination of the right credentials, targeted networking, and a clear understanding of what the work actually involves. Here’s how to position yourself for the transition.
What Medical Affairs Actually Does
Medical affairs sits between the research side of a company and the commercial side, but it’s deliberately separated from sales and marketing. The function originally emerged because regulators demanded a clear wall between medical and commercial activities. Over the past 25 years, that regulatory pressure has shifted more responsibilities to people with medical expertise, making the department larger and more influential than ever.
The work centers on scientific exchange with the healthcare community. Medical affairs teams explain new innovations and provide clinical information to doctors through educational materials, scientific publications, and direct conversations. They support clinical trials by building relationships with investigators at trial sites. They also field questions from prescribers about a company’s products. The key distinction: unlike sales reps, medical affairs professionals represent the “medical face” of the company, and their interactions are driven by science, not revenue targets.
Common Roles and What They Require
The most visible entry point is the Medical Science Liaison (MSL). MSLs work in the field, meeting with physicians and researchers one-on-one to discuss data, clinical evidence, and therapeutic developments. Most hold an advanced degree: an MD, PharmD, PhD, or sometimes a DNP. The role demands deep scientific knowledge in a specific therapeutic area and the ability to communicate it at a peer level with practicing clinicians.
Beyond the MSL track, medical affairs includes Medical Directors who oversee strategy and clinical development support, Medical Information specialists who handle incoming questions from healthcare providers, and Medical Communications professionals who produce scientific content like publications, slide decks, and congress presentations. Medical Directors typically need an MD or equivalent, while Medical Information and Communications roles can be accessible with a PharmD, PhD, or strong clinical research background.
Skills That Get You Hired
A recent competency framework developed for medical affairs professionals identified six core domains: scientific and technical knowledge, evidence generation, compliance and ethics, leadership and strategic vision, communication and collaboration, and business acumen. That’s a broad list, but it tells you something important. Pure clinical knowledge isn’t enough. You also need to understand how a business operates, how to build relationships strategically, and how to navigate the regulatory guardrails that govern everything medical affairs does.
In practical terms, the skills that matter most are:
- Data interpretation: the ability to critically evaluate clinical literature, understand trial design, and translate findings for different audiences
- Scientific communication: presenting complex data clearly, whether in a one-on-one conversation with a physician or at a company-wide meeting
- Relationship building: developing trust with key opinion leaders, investigators, and internal teams over time
- Strategic thinking: connecting scientific insights to business goals without crossing into promotional territory
How to Break In Without Industry Experience
Most people entering medical affairs come from clinical practice, academia, or clinical research. You probably won’t have “pharmaceutical industry experience” on your resume, and that’s fine, as long as you can frame what you’ve done in terms the industry recognizes. Presenting data at conferences or grand rounds translates directly. So does writing or interpreting peer-reviewed research, mentoring students or clinicians, leading clinical trial operations, and building relationships across interdisciplinary teams. These are core MSL activities under different names.
Networking is where most successful transitions actually happen. Many aspiring MSLs make the mistake of only applying online, but relationships open doors far more reliably. Start by following MSLs and medical affairs professionals on LinkedIn. Engage with their posts thoughtfully. Reach out with personalized messages that include a specific ask, something like “Would you be open to a 15-minute chat about your transition into the MSL role?” Attend webinars, virtual conferences, and industry events where you can meet people in the field. The goal isn’t to ask for a job. It’s to learn, build rapport, and stay visible so that when an opening appears, someone thinks of you.
Industry fellowships offer another structured path. Many pharmaceutical companies and professional organizations run one- to two-year fellowship programs specifically designed for PharmD graduates or other clinicians who want hands-on medical affairs training. These are competitive but provide direct industry experience and often lead to full-time offers.
Certifications That Strengthen Your Profile
The Board Certified Medical Affairs Specialist (BCMAS) credential is the main certification in this space. It covers medical affairs operations, cross-functional dynamics within life science companies, regulatory and ethical requirements, and the role of MSLs in scientific exchange and data generation. Professionals who’ve completed it describe it as a way to validate knowledge and credibility, and some report that adding the credential to LinkedIn attracted recruiter attention for MSL roles.
A certification won’t replace an advanced degree or relevant experience, but it signals serious intent to hiring managers, especially if you’re transitioning from a background that doesn’t obviously connect to pharma. It’s most valuable as one piece of a larger strategy that includes networking, skill-building, and targeted applications.
What the Day-to-Day Looks Like
If you’re considering an MSL role specifically, know that travel is central to the job. Field-based MSLs manage a geographic territory and build annual and quarterly engagement plans around the physicians and trial sites in their region. A typical week might include in-person meetings with key opinion leaders, conference coverage where you track presentations from investigators, follow-up visits to discuss protocol amendments or unmet clinical needs, and internal meetings to share field insights with your company’s strategy team. Documentation and travel planning fill the gaps.
Many companies now supplement travel with virtual engagements, especially for follow-up discussions. A few roles are almost fully remote, but they still require periodic conference attendance and strategic in-person visits. Complete avoidance of travel is rarely realistic. MSL salaries reflect these demands and are typically among the most competitive in medical affairs.
Non-field roles like Medical Information or Medical Communications involve less travel but more desk-based work: responding to medical inquiries, developing scientific content, reviewing promotional materials for accuracy, or supporting publication strategies. These roles can suit people who want to work in pharma without the road-warrior lifestyle.
Navigating the Interview Process
Medical affairs interviews, particularly for MSL positions, almost always include a scientific presentation. You’ll be asked to prepare a PowerPoint on a clinical topic and present it as if you were speaking to a physician. This stage is where many candidates fail, not because they lack scientific knowledge, but because their presentation skills aren’t polished enough. Interviewers are evaluating your ability to distill complex data, hold an audience, and handle questions on the fly, exactly what you’d do in the field every day.
Prepare by practicing your presentation with someone who can give honest feedback. Focus on clarity over comprehensiveness. Structure your slides around a clinical question and walk through the evidence the way you’d explain it to a busy specialist who has ten minutes. If you’ve presented at conferences, journal clubs, or grand rounds before, you already have the foundation. Tighten it for a corporate audience that cares about precision and confidence in equal measure.
Earlier interview stages typically include phone screens with recruiters and behavioral interviews with hiring managers. Expect questions about how you’ve built professional relationships, handled disagreements over scientific interpretation, and communicated complex information to non-experts. Every answer should connect back to the core of what medical affairs does: bridging science and the people who use it.
