BioMarin Pharmaceutical – Why Work For Us?

Rare Opportunities, Personal Impact

BioMarin is a world leader in developing and commercializing innovative biopharmaceuticals for rare diseases driven by genetic causes

At BioMarin, we focus on developing first-in-class and best-in-class therapeutics that provide meaningful advances to patients who live with serious and life-threatening rare genetic diseases. BioMarin remains steadfast to its original mission—to bring new treatments to market that will make a big impact on small patient populations. These patient populations are mostly children, suffering from diseases so rare, that the entire patient population can number as few as 1,000 people worldwide. These conditions are often inherited, difficult to diagnose, progressively debilitating, have few, if any, treatment options, and are usually ignored.

Time is critical to patients with rare diseases, and we strive to quickly develop important therapies for them. The efficiency and speed of our research, development, manufacturing, and commercial efforts is at the heart of our ability to urgently deliver therapies. Our track record of developing and commercializing new treatments has been significantly faster than the industry average and is ingrained in our culture. CenterWatch, a leading source for global clinical trial information, has named it one of the fastest drug developers in the industry. BioMarin was also ranked tenth on Forbes list of innovative companies in 2015.

As a biopharmaceutical company, our success stems from our focus on science and the hope our therapies can bring to patients. We are world leaders in metabolic disease innovation with multiple products commercialized and a growing pipeline of product candidates to address unmet medical needs. We continue to fuel our R&D engine by looking for opportunities that align with our strengths and competencies. And we relentlessly pursue exciting, early-stage science that has the potential to change the course of disease.

A constant in BioMarin’s culture is how patients continue to drive us. The passion and dedication that our employees bring to work each day is a testament to the inspiration our patients provide, and the knowledge of the impact we can make in their lives.


What makes working here unique? At BioMarin, we feel the intense tie between the work we do and the life-changing results it delivers. Our focus on rare disease gives us the rare opportunity to truly impact lives.

As employees, we’re here because we want to be here. We enjoy our work — and each other. Our people are smart. Unassuming. Collaborative. Curious. Interesting. We share a passion for shared accomplishment — across teams and across borders — and are committed to our people, our purpose, and most of all, our patients. This common ground elevates the impact each of us is able to make every single day.

Our appetite for science drives us. Our team members motivate us. And our patients inspire us. Together we’re growing a company unlike any other, because our motivation is unlike any other.


At BioMarin, we’re inspired, driven, and empowered by the patients who benefit from our therapies. Continually fueling our R&D engine, we look for opportunities to develop first-in-class and best-in-class therapeutics to make a meaningful impact on the lives of those with rare genetic diseases.

Careers at BioMarin include:


From research and discovery to post-market clinical development, our R&D engine involves all bench and clinical research and the associated groups that support those endeavors. Our teams work on developing first-in-class and best-in-class therapeutics that provide meaningful advances to patients who live with rare diseases.


Our manufacturing and process development teams manage the production of our therapies for clinical trials and commercial markets. These engineers, technicians, scientists, and support professionals continually provide quality assurance and ensure we meet all regulatory standards. We have manufacturing facilities in Northern California and in Cork, Ireland. Additionally, our supply chain teams procure the goods and services needed to support manufacturing and worldwide distribution.


Be part of the worldwide infrastructure that gets our drugs to underserved patients around the world. Our global sales force solidifies BioMarin’s commercial presence in the United States and Europe and is rapidly growing in other regions, such as South America, EuMEA, and Asia-Pacific.


It takes a village, and at BioMarin, our general and admin teams are the village behind our success. From the IT experts who manage our technology to the human resources professionals who hire the people who make it all possible, these teams support our organization and span all areas of operations.

What do you enjoy most about working at BioMarin? The scientific approach. At BioMarin, we look at the science behind things and justify what we do from there. It’s unique, and it’s exciting. Our orphan drug status means that our timelines are very short comparatively. It’s also very patient-focused. Management makes a big effort to make sure we, as employees, are aware of our patients’ stories — that we know who we are working for, which is really motivating. There is also a high caliber of people here. We need people with diverse backgrounds — in education and beyond — to address the need for different product aspects.      

Do you see BioMarin as a leader? How so? I would say BioMarin is a leader in innovation. We operate under a different model — we’re not trying to replicate big pharma. We deliver orphan drugs, which means our timeline to market is much faster than at many biopharm companies. This is also a place where, if you have an idea about how something might be done better — there is a forum for your ideas to be heard. We all work together with one goal in mind, and it makes us all really feel like true contributors. We’re working on a lot of new, pioneering technology — things that have never been done before. Gene therapy is exciting and potentially groundbreaking. It takes a lot of courage to be a leader in new technologies, and I think we do it successfully at BioMarin.     

What should candidates know about BioMarin?  BioMarin is at a really great, fantastic stage. It’s big enough that we’re not a startup, but not so big that there isn’t room to have a strong and important impact on our future. The company has more than doubled in the past year, and with tremendous growth comes opportunity.   Beyond that, BioMarin is just a great company to work for, and the work you do is both challenging and fulfilling. I feel that I have a lot of impact on the products I work on, testing, information in submissions, the manufacturing processes themselves. I do not feel that this level of personal influence would be the same at a larger company. It’s very rewarding.

    I have been working at BioMarin Pharmaceutical full-time (More than 5 years)


    I've been here for more than five years, and I love Mondays! I still pinch myself because I get to work in such a positive work environment. I have so much respect for the people here, who are brilliant and humble--a rare combination of traits. It is highly motivating to work for a company that has a clear purpose focused on helping people with rare genetic diseases. It is an exciting time to be at BioMarin while it is growing rapidly and to be a part of cutting edge science.


    Fast growth in the company means that sometimes you have to be okay with ambiguity.
