Job Description & How to Apply Below
Position: Associate Scientist - 26-00123
  • 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
  • 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 Tecan and Hamilton 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 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.
