Associate Scientist, Bioproduction

Associate Scientist, Bioproduction — Newark, CA | Full-Time

ATUM is a leading bioengineering solution provider transforming discovery science into a rigorous engineering discipline. We are seeking an experienced Upstream Bioprocess Associate Scientist to join our Bioproduction unit. This is a pivotal role where you will execute bioreactor scale‑up processes, supporting the journey from synthetic gene design to large‑scale protein production. While we utilize high‑throughput systems, this role focuses heavily on the engineering and execution of larger‑scale production runs.

• Bioreactor Operations:
  Lead the setup, inoculation, and maintenance of suspension culture bioreactors (ranging from 3L to 50L).
• Process Engineering:
  Monitor and optimize critical parameters including pH, DO, mass flow settings, and agitation strategies to ensure successful scale‑up.
• Seed Train & Maintenance:
  Perform seed train operations within a BSC and manage media preparation, probe calibrations, and glassware sterilization.
• Harvest & Analytics:
  Execute harvest operations and end‑of‑run tasks; operate and maintain analytical suite (e.g., Vi‑CELL, NovaFlex2).
• Collaboration:
  
  Partner with the Scientist team to troubleshoot runs and translate bench‑scale successes into robust production protocols.

• Education:
  
  BS/MS in Chemical Engineering, Bioengineering, Molecular Biology, or a related field (1–3 years of industry experience required).
• Bioprocess Expertise:
  Proven track record in upstream process development and experience with larger‑scale glass or disposable bioreactors.
• Preferred Systems:
  Experience with am ®15 and am ®250 systems is not required but is highly desired.
• Attention to Detail:
  Meticulous record‑keeping and a high standard for lab documentation.
• Communication:
  Strong interpersonal skills with a "team‑first" mindset and the ability to multitask in a fast‑paced environment.

• Must be able to perform standard lab movements (pipetting, pouring reagents, handling up to 25lbs).
• Flexibility to work a Sunday–Thursday or Tuesday–Saturday schedule to align with bioreactor cycles.

• Free daily catered lunch, comprehensive health benefits, PTO, and a 401(k) with a Safe Harbor plan.
