More than one million people in the United States today are fighting blood cancer. While a traditional allogeneic stem cell transplant has been the best hope for many, the transplant itself can prove fatal or lead to serious conditions, such as graft vs. host disease. Orca Bio is a late-stage biotechnology company redefining the transplant process by developing next-generation cell therapies with the goal of providing significantly better survival rates with dramatically fewer risks. With our purified, high-precision investigational cell therapies we hope to not only replace patients' blood and immune systems with healthy ones, but also restore their lives.

We have built a state-of-the-art, 100,000-square-foot manufacturing facility in Sacramento, CA (7910 Metro Air Pkwy) to ensure the consistent and reliable delivery of our high-precision cell therapy products. This site is essential to advancing our clinical pipeline and supporting future commercial availability of our life-saving therapies.

Summary:

In this Sacramento-based role, reporting into our VP/Head of CMC, you will lead the design, development, validation, and lifecycle management of analytical methods supporting cell therapy programs. This role will provide strategic and technical leadership with a strong emphasis on advanced flow cytometry, method validation, and cell-based assays. The ideal candidate brings deep expertise in cell therapy analytics, a proven track record in regulatory submissions, and demonstrated success in building and leading high-performing scientific teams.
