Location: Oceanside, CA. Onsite 5 days per week.

Position Summary
We are seeking a highly motivated Associate Scientist to support purification process development during pivotal and commercial development phases. This contract role focuses on high-throughput purification of upstream/cell culture samples and supports downstream purification characterization studies. A core part of this role is the development and optimization of high-throughput purification assays using state-of-the-art automation platforms (e.g., Tecan, Hamilton).

The ideal candidate brings strong hands-on laboratory skills, deep familiarity with HTP purification methods, and the ability to establish, troubleshoot, and refine automated workflows.

Key Responsibilities
High-Throughput Purification & Automation

• Execute high-throughput purification (HTP) workflows for upstream/cell culture samples to support process characterization.
• Operate, optimize, and maintain automated liquid handling systems such as Hamilton and Tecan platforms.
• Develop, qualify, and refine HTP purification assays and microscale purification methods.
• Collaborate with upstream teams to ensure timely sample processing and data delivery.

Purification Process Development

• Contribute to experimental design and execute purification process development and characterization experiments.
• Conduct bench-scale purification studies using chromatography, filtration, and microscale systems.
• Collect, analyze, and interpret experimental data in compliance with data integrity expectations.
• Prepare high-quality protocols, reports, and electronic laboratory notebook documentation.

Technical Excellence & Collaboration

• Support implementation of new purification technologies, instrumentation, and platform enhancements.
• Maintain a state-of-the-art purification lab, including instrumentation readiness and workflow improvements
• Partner with upstream, downstream, and cross-functional colleagues as needed on development and characterization initiatives.
• Follow all compliance, training, and safety requirements.

Qualifications / Skills / Experience

• M.S. with 2+ years or B.S. with 4+ years of relevant industry experience in chemical engineering, biochemistry, bioengineering, or related discipline.
• Expertise in developing and executing HTP purification assays, including automated liquid handling systems such as Tecan, Hamilton, and microscale chromatography platforms.
• Experience with chromatography (e.g., AKTA, plate-based), filtration, and standard downstream techniques.
• Strong analytical, documentation, and problem-solving skills.
• Ability to work both independently and in collaborative, fast-paced environments.
• Excellent interpersonal, verbal, and written communication skills.
