Position Summary:

The Viral Vector Process Development Senior Scientist / Scientist is a part of a growing Virology Team and is responsible for viral vector process and analytical development supporting Atara’s T-cell therapy programs. 

This role is responsible for designing and implementing viral vector strategies for upstream and downstream process development. This position works closely with external contract laboratories on viral vector studies to support external manufacturing. The person also transfers viral processes and assays in-house and performs laboratory studies.

This position includes master and working cell bank and viral seed stock production, viral vector production and purification, virus process development and scale-up, development of in-process controls and virus analytical methods to support manufacturing and lot release, managing experimental plans and schedules, experimental design, statistical data analysis, and interpretation. This role authors technical protocols and reports, drafts batch records and SOPs. The position also reviews regulatory filings, including specifications, validation, comparability, trend analysis, risk assessment, and product quality attributes. The role interacts cross-functionally within the process sciences and analytical organizations, as well as with other departments (regulatory, quality, manufacturing, clinical, supply chain) supporting IND and Marketing Application filings.

The candidate should have successfully demonstrated viral vector process development, production, and analytics, as well as personal attributes including initiative, independent thinking and collaboration skills.

More About Atara Bio
Now in our sixth year, we’re proud of our team of 260+ Atarians co-located by design in South San Francisco (corporate headquarters) and Southern California (R&D and manufacturing headquarters in the northwest Los Angeles area) with a newly-established European headquarters in Zug, Switzerland. Atara also has a R&D site in the Denver, Colorado area and an office in New York City. Our Southern California hub is anchored by a new 90,000 sq. ft., state-of-the-art Atara T-Cell Operations and Manufacturing (ATOM) facility in Thousand Oaks, California.

One mission – “Transform the lives of patients with serious medical conditions through pioneering science, teamwork and expertise” – and a singular vision – “Cell therapy treatment for every patient, any time – provide inspiration and direction for all of us.”

The Company's off-the-shelf, allogeneic T-cells are bioengineered from donors with healthy immune function and allow for rapid delivery from inventory to patients without a requirement for pretreatment. Atara's T-cell immunotherapies are designed to precisely recognize and eliminate cancerous or diseased cells without affecting normal, healthy cells.

Atara's most advanced T-cell immunotherapy in development, tabelecleucel, or tab-cel™ (formerly known as ATA129), is being developed for the treatment of patients with Epstein-Barr virus (EBV) associated post-transplant lymphoproliferative disorder (EBV+ PTLD) who have failed rituximab, as well as other EBV-associated hematologic and solid tumors, including nasopharyngeal carcinoma (NPC). Tab-cel™ is in Phase 3 clinical development for the treatment of EBV+ PTLD following an allogeneic hematopoietic cell transplant (MATCH study) or solid organ transplant (ALLELE study).

Atara is also developing off-the-shelf, allogeneic ATA188 and autologous ATA190 T-cell immunotherapies using a complementary targeted antigen recognition technology for specific EBV antigens believed to be important for the potential treatment of multiple sclerosis (MS). A Phase 1 clinical study of autologous ATA190 in patients with progressive MS is ongoing. Atara is also advancing a Phase 1 clinical study of ATA188 in patients with progressive or relapsing-remitting MS across clinical sites in the United States and Australia. Atara's clinical pipeline also includes ATA520 targeting Wilms Tumor 1 (WT1) and ATA230 directed against cytomegalovirus (CMV).

Working at Atara Bio
People at Atara Bio are high integrity, roll-up-your-sleeves, get-it-done types who are keenly committed to putting patients first, advancing medical care and doing so with demonstrated urgency. At their core Atarians are people who work well with others and are “team-centric”, have purposeful curiosity and can’t wait to save patient lives. And similar to other biotech companies who have so many accomplished people, we expect humility (we are a “low hubris” sort of place), flexibility, respect, teamwork, good judgment and getting the most out of any dollar we spend. We also expect to enjoy the journey (and each other) as we move forward with a shared responsibility to teach and to learn from what we do and from our teammates.
