Description

Who We Are

BioMarin is a global biotechnology company that relentlessly pursues bold science to translate genetic discoveries into new medicines that advance the future of human health.

Since our founding in 1997, we have applied our scientific expertise in understanding the underlying causes of genetic conditions to create transformative medicines, using a number of treatment modalities.

Using our unparalleled expertise in genetics and molecular biology, we develop medicines for patients with significant unmet medical need. We enlist the best of the best – people with the right technical expertise and a relentless drive to solve real problems – and create an environment that empowers our teams to pursue bold, innovative science. With this distinctive approach to drug discovery, we’ve produced a diverse pipeline of commercial, clinical and preclinical candidates that have well-understood biology and provide an opportunity to be first-to-market or offer a substantial benefit over existing therapeutic options.

 

Senior Executive Assistant to the CEO
 
We are seeking an exceptional Senior Executive Assistant to support the Chief Executive Officer of BioMarin. This opportunity arises following the retirement of a long-serving executive assistant and requires a polished professional who thrives in a fast-paced, dynamic environment and is motivated by the opportunity to elevate leadership impact across the organization.
 
More than an administrative partner, the Senior Executive Assistant will serve as a trusted extension of the CEO—anticipating needs, taking initiative, and creating leverage so the CEO can focus on the most critical priorities. In addition, this role provides the opportunity to influence and support the administrative community; encouraging teamwork, fostering collaboration and building a collegial, collaborative environment.  
 
This position is highly cross functional and global in scope, requiring the ability to navigate multiple time zones, cultures and priorities while serving as a unifying liaison for the CEO across BioMarin‘s global footprint.
 
What You’ll Do
 
  • Serve as the strategic right-hand; anticipating needs, taking initiative, and creating leverage so the CEO can focus on critical priorities.
  • Lead by example for the broader administrative team—coaching, convening, and developing peers, fostering recognition, and ensuring collaboration across sites.  This includes responsibility of one official direct report. 
  • Orchestrate complex scheduling, travel, communications, and board preparation with discretion, accuracy, and efficiency.
  • Serve as a trusted liaison for the CEO with Board of Directors, senior leaders and external partners – ensuring seamless preparation and execution of meetings while representing the executive office with professionalism, poise and executive presence. 
  • Partner in building and sustaining company culture by supporting offsites, events, and initiatives that strengthen engagement across BioMarin’s global sites.
  • Support the CEO and fellow administrative professionals in leveraging digital tools—including emerging technologies like AI—to drive efficiency and unlock new ways of working.
  • Draft, review, and refine executive-level communications, presentations, and reports with clarity, accuracy, and professional polish.
 
What You Bring
 
  • 10+ years of experience supporting C-suite or senior executives in complex, global, or high-growth organizations.
  • A reputation for being proactive, kind, and highly attuned to anticipating the needs of executives.
  • Demonstrated success managing board-level interactions and senior leadership teams.
  • Exceptional organizational skills with the ability to manage multiple, shifting priorities in high-pressure environments.
  • Superior written and verbal communication skills, with executive-level polish.
  • Strong problem-solving ability and creativity in approaching challenges.
  • Experience mentoring or leading administrative professionals.
  • Proven fluency with modern digital tools and platforms; comfort guiding others in navigating emerging technologies.
Work Hours/Location: This is a full time, onsite role based at BioMarin HQ in San Rafael, CA.  You will typically work onsite every day alongside other Executive Assistants, remote work offered as appropriate – for example, when CEO is traveling or for other special circumstances.
 
Why Join Us?
This is a unique opportunity to directly support the CEO of a global biotechnology leader, helping drive organizational impact and supporting the mission to bring life-changing therapies to patients around the world. In this role, you will help shape the success of BioMarin’s executive office, contribute to the growth and culture of the company, and gain exposure to strategic decision-making at the highest levels. You’ll collaborate with talented colleagues worldwide and play a critical role in enabling the future of an innovative, mission-driven organization.
