Biosimilars Jobs (NOW HIRING)

Element Ann Arbor is currently seeking a highly experienced Principal Scientist – Bioseparation to lead and execute advanced analytical method development, characterization, and validation of large molecule therapeutics across discovery, development, and late-stage CMC. This is an onsite, laboratory-based role with significant hands-on responsibility in bioseparation sciences, supporting a broad range of biologics modalities including proteins and recombinant proteins, peptides and peptide-drug conjugates, monoclonal antibodies (mAbs) and biosimilars, antibody-drug conjugates (ADCs), mRNA therapeutics, DNA constructs (including plasmid DNA and oligonucleotides), viral vectors, and other complex or emerging modalities such as fusion proteins, multispecifics, and engineered biologics.

• Lead development, optimization, and troubleshooting of bioseparation-based analytical methods supporting biologics across discovery, development, and late-stage CMC, including orthogonal analytical strategies for comprehensive characterization
• Perform hands-on execution and technical leadership across a broad range of modalities, including proteins and recombinant proteins, peptides and peptide-drug conjugates, monoclonal antibodies (mAbs) and biosimilars, antibody-drug conjugates (ADCs), mRNA therapeutics, DNA/plasmid DNA/oligonucleotides, viral vectors, and emerging complex biologics (fusion proteins, multispecifics, engineered constructs)
• Apply deep expertise in chromatography platforms (HPLC/UPLC/UHPLC, SEC, IEX, HIC, RP-HPLC, affinity chromatography), mass spectrometry (LC-MS/MS, high-resolution MS, SEC-MALS, native MS, MAM workflows, glycan/PTM characterization), capillary electrophoresis (CE-SDS, cIEF, purity/identity assays), and supporting biophysical techniques (DLS, DSC, UV/fluorescence, MALS, CD, FTIR)
• Lead analytical strategy for complex biologics programs, including method development, qualification, validation, transfer, comparability, stability, forced degradation, and full characterization studies
• Ensure development of robust GMP-compliant methods aligned with ICH Q2/Q6, USP, EP, and GMP requirements, and support regulatory submissions (IND, BLA, IMPD) with high-quality analytical data packages
• Drive innovation in analytical science, including implementation of MAM workflows, high-throughput LC-MS platforms, automated bioseparation methods, and evaluation of emerging technologies in biologics characterization
• Provide scientific leadership and mentorship to junior scientists, including troubleshooting complex bioseparation and mass spectrometry challenges and establishing best practices in analytical development and execution

• BS in Analytical Chemistry, Biochemistry, Pharmaceutical Sciences, or related field required; Master's degree or higher preferred, but not required.
• Extensive industry experience in biologics analytical development is highly desirable
• 8–15+ years of experience in biopharmaceutical or CRO analytical development with strong hands-on expertise in bioseparation of large molecules
• Deep technical expertise across analytical platforms, including LC/UPLC/SEC/IEX/HIC/RP chromatography, LC-MS and high-resolution mass spectrometry, CE-SDS, cIEF, SEC-MALS, and complementary biophysical techniques
  Strong scientific knowledge of protein structure and higher-order structure, monoclonal antibodies and biosimilars, antibody-drug conjugates (ADCs), engineered biologics, and nucleic acid-based therapeutics (mRNA, DNA, oligonucleotides)
• Demonstrated experience in comparability, stability studies, and degradation pathway analysis for complex biologics
• Preferred experience includes CRO or client-facing analytical project execution, MAM workflows, advanced LC-MS analytics, glycan mapping and PTM quantification, and automation/high-throughput analytical systems
• Strong scientific writing capability with experience supporting regulatory documentation and submissions
• Proven ability to execute in onsite laboratory environments with strong hands-on bioseparation and multi-platform analytical integration skills
• Ability to manage complex biologics programs in fast-paced, matrixed environments with strong problem-solving and scientific reasoning capabilities
• Effective communicator across scientific, regulatory, and operational stakeholders

Physical Demands:

• Frequency of required physical force: Minimum (moderate)
• Lifting requirements: lifting <50 lbs. often and >50 lbs. on occasion
• Ability to stand on feet for long periods of time
• Ability to lift 50+lbs periodically
