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.

Key Responsibilities

• 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.

Qualifications

• 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 ambr®15 and ambr®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.

Physical Requirements & Availability

• 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.

Why ATUM?

• Innovative Environment: Be at the forefront of the next-gen biotech revolution in Quantitative Biology.
• Culture of Excellence: Enjoy a collaborative atmosphere with excellent growth opportunities.
• Perks & Benefits: Free daily catered lunch, comprehensive health benefits, PTO, and a 401(k) with a Safe Harbor plan.

Compensation: $85K-$95K, DOE
