Alector is a biotechnology company that applies immuno-neuroscience to develop therapies for neurodegenerative and oncological diseases. The organization maintains a workforce of roughly 200 employees worldwide, with hiring activity that is currently outpaced by departures. This modest contraction suggests a period of recalibration as the company aligns staffing with its clinical and operational priorities.
Engineering is Alector’s largest department at 70 employees, reflecting the emphasis the company places on research tools, data science, and platform development. Clinical and healthcare functions account for 29 team members, while Business Management (25) and Operations (19) support day-to-day execution. Finance and Administration, Human Resources, and Sales & Support collectively add another 37 employees, indicating a balanced mix of scientific and corporate roles. Smaller groups in Quality and Program Management round out the structure, providing specialized oversight for trials and cross-functional initiatives.
Over half of Alector’s staff is based at its San Francisco headquarters, home to approximately 105 employees. An additional 77 team members work remotely or from dispersed locations classified as “Other,” underscoring the company’s flexible talent model. Small satellite offices in Los Angeles, San Diego, Seattle, Denver, Philadelphia, Pleasanton, Sunnyvale, and Lebanon each host between two and seven professionals, allowing Alector to tap regional talent without building large physical footprints.
