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 of Muscle Biology will be a highly driven scientific leader who is dedicated to performing great science that transforms patients’ lives. They are a dedicated drug hunter and will lead the development of our Muscle Franchise strategy and portfolio. The successful candidate will partner with colleagues in FulcrumSeek™, medicinal chemistry, DMPK and in vivo pharmacology to translate this team’s scientific discoveries into new medicines. This is a forward-facing leadership role, requiring cross-functional collaboration, establishing liaisons with KOLs, and routine interface with members of the Executive Team. As a highly experienced scientist, the Director of Muscle Biology is expected to play a large role in the mentorship and development of their team, teaching what “good” looks like in drug discovery. They should maintain a strategically focused lab and should be able to lead by example.

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.

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.
