Recruits Lab places Medical Science Liaisons, Senior MSLs, and Field Medical Directors at biotech, pharma, medical device, and diagnostics companies. We source MSLs with KOL relationships, launch experience, and the scientific depth your therapeutic area requires. Average hire time: 14 days.
Medical Science Liaisons are the scientific face of a therapy in the field. They build KOL relationships, support investigator initiated trials, deliver scientific exchange, and feed real-world insight back into medical and commercial. For launch-stage biotech, the MSL team is the most important hire after the CMO.
Recruits Lab is a Medical Science Liaison recruiting firm working with biotech, pharma, medical device, and diagnostics companies preparing for or executing commercial launch. We place MSLs across oncology, neuroscience, rare disease, immunology, cardiology, and platform therapeutic areas.
We focus on three profiles: launch MSLs who have brought a therapy from approval through first 12 months in market, established MSLs with deep KOL networks in your therapeutic area, and Field Medical Directors who lead a regional or national MSL team. Each has a different pool and a different sourcing motion.
Most candidates we place hold a PharmD, PhD, or MD and have 3-10 years of field medical experience. We screen for therapeutic area depth, KOL portability, launch experience, and the ability to operate independently in a small medical affairs team — which is the actual reality of biotech MSL roles.
Our subscription model fits full MSL team builds across multiple regions. Our flat 20 percent contingency fits one-off senior hires and Field Medical Director searches. Every placement carries a 90-day replacement guarantee.
Why this market is hard to recruit for. And how we solve each one.
An oncology MSL is not interchangeable with an immunology MSL. KOL networks do not port across therapeutic areas. We match on real TA experience.
MSLs who have launched a therapy from approval through year one in market are a small slice of the pool. We track them and know when they are open to a move.
MSL territories are geographically bounded. We pre-qualify candidates on territory residency, since the right MSL must live in the region they cover.
Many strong MSLs at large pharma struggle in lean biotech where they have to do everything themselves. We screen for biotech readiness.
MSL roles are heavily regulated. We screen for clean compliance history and PhRMA / OPDP awareness.
Strong MSLs get retention packages from current employers. We manage the resign conversation directly.

Hiring an MSL requires therapeutic area depth, regional residency, and KOL portability. Most generic recruiters miss on at least one. Recruits Lab runs TA-calibrated MSL searches that close in 14-21 days using launch-experienced and region-resident candidates.
Industry average is 60-120 days for an MSL search. Recruits Lab averages 14 days from kickoff to signed offer for venture-backed biotechs by combining region-calibrated sourcing with launch-experienced pools.
An MSL is a medical affairs role focused on scientific exchange with KOLs, investigator initiated trial support, and field medical insight. A sales rep is a commercial role focused on prescriber-level promotion. MSLs do not detail product or sell, and they report into medical affairs, not commercial.
Launch-stage biotechs typically build medical affairs (MSL team plus Field Medical Director), regulatory leadership, and commercial leadership in parallel during the 9-12 months before approval. Recruits Lab runs coordinated multi-role searches under subscription to keep timelines aligned.
Approval expected in 9 months. Needed to build a 6-person MSL team across 4 regions and hire a Field Medical Director, all with oncology launch experience. Internal HR had filled 1 of 7 roles in 5 months.
Recruits Lab embedded a dedicated medical affairs recruiter on subscription. Built region-by-region target maps, ran parallel outreach across all 4 regions, and coordinated start dates to match launch readiness.
All 7 roles signed in 4 months. Full MSL team in seat 8 weeks before approval. Total cost was less than 30 percent of comparable retained search fees.
"Recruits Lab built our entire MSL team across four regions in one quarter. We would have been mid-launch with half a team if we had kept trying to do it internally."
"Their outreach actually mentions our therapeutic area and the KOLs the role would cover. That alone changes response rates."
