Seeking multiple Process Development scientist roles for Downstream.

The Process Development scientist will develop, optimize, and scale downstream purification processes for biologics, including viral vectors and bacteriophages, to support client programs and manufacturing technology transfer. Responsibilities include clarification, chromatography, tangential flow filtration and final filtration, with emphasis on product recovery, purity and process consistency.

This opening may be filled at the Associate Scientist, Scientist I, Scientist II or Scientist III level based on relevant education, experience, and demonstrated technical capability. Scope, independence and technical leadership will be commensurate with the appointed level.

This position is in the Bryan-College Station area and requires on-site work five business days per week, with off-shift and weekend work as required.

How you will make an impact:

Execute downstream studies in clarification, chromatography, ultrafiltration/diafiltration and final filtration; analyze recovery, impurity clearance and process performance, and propose solutions.

Author or assist with protocols, SOPs, process descriptions, technical reports and manufacturing batch record content; present findings to team members, leadership and clients as appropriate to level.

At Associate Scientist / Scientist I levels, execute assigned studies with guidance appropriate to experience. At Scientist II / III levels, independently design and lead studies, troubleshoot processes and train colleagues.

At Scientist III level, serve as a downstream technical SME, assess client processes for GMP suitability and scale-up needs, and lead downstream technology transfer with technical support to Manufacturing.

At Scientist III level, lead onboarding and training, assist with recruitment and interviews, and propose improvements to methods, documentation, procedures and safety.

Operate and maintain automated chromatography systems (e.g., AKTA), TFF systems, clarification and filtration equipment, pumps, balances, tubing welders/sealers and pH/conductivity meters; prepare buffers and solutions.

Maintain laboratory readiness, equipment records, consumables and reagents; follow cleaning, contamination control and safe material-handling procedures.

Collaborate with PD, Analytical Development, Manufacturing, Quality and other stakeholders; support study planning, scheduling and resource estimates as appropriate to level.

Maintain clear communication with the team and leadership. Perform other duties as required.

As a future Matican you bring:

Education
