Company Overview

Fulcrum Therapeutics is a clinical-stage biopharmaceutical company focused on improving the lives of patients with genetically defined rare diseases in areas of high unmet medical need. Fulcrum’s two lead programs in clinical development are losmapimod, a small molecule for the treatment of facioscapulohumeral muscular dystrophy (FSHD) and FTX-6058, a small molecule designed to increase expression of fetal hemoglobin for the treatment of sickle cell disease and other hemoglobinopathies, including beta-thalassemia. The company’s proprietary product engine, FulcrumSeekTM, identifies drug targets that can modulate gene expression to treat the known root cause of gene mis-expression.


Reporting to our Chief Scientific Officer, The Director and Head of Medicinal Chemistry will be a highly driven scientific leader who is dedicated to transforming novel target biology into innovative first-in-class medicines. They are a dedicated drug hunter and will be responsible for the design, synthesis, and optimization of small-molecule drug candidates, from hit identification through Development Candidate selection. In this strategic role, the successful candidate will engage with colleagues in FulcrumSeek™ and in exploratory biology, and will drive insights in novel target biology to transformative new medicines. Specifically, this individual will optimize small molecule “hits” by identifying structure-activity relationships and thereby design novel chemical entities optimized for potency, selectivity, pharmacokinetics, in vivo efficacy, and overall pharmaceutical properties. You will collaborate with a dynamic multi-disciplinary team of biologists and pharmacologists, and you will also manage and lead a large team of synthetic chemists at our external CROs. As our Head of Medicinal Chemistry, you will have collaborative engagement with the external scientific community, routinely present to our Executive Team, and make direct contributions to Fulcrum’s external reputation.


  • ”Own” the medicinal chemistry function at Fulcrum, bringing in new capabilities as required, identifying key collaborators and CROs, and inspiring best-in-class approaches to small molecule drug discovery
  • Further cultivate and lead our consortium of thought leaders and consultants in medicinal chemistry, structural biology and machine learning/AI to bring best-in-class innovation to our drug discovery workstreams
  • Develop strategies and tactics for ‘drugging’ the novel target biology identified from our FulcrumSeek platform and our exploratory biology efforts
  • Design new bioactive compounds by collaborating with your colleagues in the biological sciences to optimize potency, selectivity, DMPK, in vivo pharmacology, and pharmaceutical properties
  • Refine our outsourcing strategy with our external CROs, and lead the efforts of a large team of synthetic chemists in the focused and effective optimization of our drug leads
  • Identify novel composition-of-matter, and liaise with our patent attorneys to create intellectual property strategies that leverage our inventions


  • Ph.D. in synthetic organic chemistry or equivalent with 10+ years of industry experience
  • Proven track record in drug discovery; has served as a project team leader or co-leader or key innovator for a discovery program that successfully identified an IND candidate; routine inventor/co-inventor of composition-of-matter IP
  • Excellent knowledge of medicinal chemistry; conversant in project biology and pharmacology, and with treatment modalities beyond small molecules
  • Demonstrated excellence in organic synthesis; conversant with principles of structure-based drug design and in silico/AI/ML approaches to both structure- and ligand-based drug design
  • Exceptional knowledge of ADME, physicochemical, biochemical and pharmacological principles as applied to drug discovery
  • Proven leadership capability in cross-functional team settings, either as project team leader or co-lead
  • Exceptional interpersonal, verbal and written communication skills, and able to present the rationale, key data, issues and accomplishments of our drug discovery efforts to internal and external collaborators

Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Why are you being asked to complete this form?

We are a federal contractor or subcontractor required by law to provide equal employment opportunity to qualified people with disabilities. We are also required to measure our progress toward having at least 7% of our workforce be individuals with disabilities. To do this, we must ask applicants and employees if they have a disability or have ever had a disability. Because a person may become disabled at any time, we ask all of our employees to update their information at least every five years.

Identifying yourself as an individual with a disability is voluntary, and we hope that you will choose to do so. Your answer will be maintained confidentially and not be seen by selecting officials or anyone else involved in making personnel decisions. Completing the form will not negatively impact you in any way, regardless of whether you have self-identified in the past. For more information about this form or the equal employment obligations of federal contractors under Section 503 of the Rehabilitation Act, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
