Salaried, full-time
/ On-site
Summary:  Arbor is a preclinical stage company with a growing pipeline of gene-editing programs. Our CMC Analytical Development team is looking for a Senior Scientist who will play a critical role in delivering life-changing complex biotherapeutics to patients using cutting edge technologies. This role will report to the Director of CMC Analytical Development and will drive CMC analytical activities in-house and with CDMOs to move therapeutic candidates into a cGMP environment in a phase-appropriate manner. If you are looking for an entrepreneurial, science-driven, collaborative environment then Arbor is the place for you. 

Job Description:
The Senior Scientist will help develop the strategy and execution of CMC analytical activities to support complex gene-editing therapeutics. The ideal candidate will thrive in a collaborative setting, working on cutting edge technology and helping transition products from R&D to GMP by championing Arbor’s CMC needs internally and externally. This role is primarily lab-based and requires proven technical expertise with relevant biochemical methodologies, including, but not limited to analytical methods for structural characterization, physicochemical properties, and product and process related impurities for gene-editing therapeutics. Experience in both upstream and downstream processing is highly desirable. The candidate will work closely with Arbor R&D and CDMOs to develop, optimize, and transfer analytical capabilities in a phase-appropriate manner. The Senior Scientist will also support the initiation and execution of early Analytical Quality Control activities including specification development, stability studies, product comparability, reference standard programs. 


    • Develop internal analytical capabilities, as well as relationships with external organizations (CDMOs/CRDOs) to support in-process, release, stability, and characterization testing of complex drug products. 
    • Author, review and approve technical documents such as test procedures, protocols & reports, investigations/deviations, and relevant regulatory submission documents (e.g., IND, IMPD, BLA, MAA). 
    • Work collaboratively with internal and external personnel as a hands-on analytical scientist to provide technical expertise in method development, transfer, performance, and troubleshooting, to evaluate new technologies, and to transition research methods to the GMP space.  
    • Represent CMC Analytical Development on cross-functional CMC teams. 
    • Identify and establish critical quality attributes and implement control strategies to support Arbor’s pre-clinical toxicology and clinical development programs. Analytical activities include identification of CQAs, specification development, release and stability testing, reference standard qualification, product comparability, and structure function relationship studies. 
    • Serve as an analytical SME for technical input and review of investigations for aberrant results, OOT/OOS, and investigations internally and at contract organizations. 
    • Support Analytical/Product Development in aspects of technology transfer, process scale-up, and process validation activities at contract organizations and with partners. 


    • Degree in a scientific discipline (preferably a Ph. D), with demonstrated subject matter expertise in analytical development and at least 5 years working in biopharmaceutical organizations. 
    • Expert knowledge of biophysical and biochemical analytical methods such as qPCR, ddPCR, ELISA, microfluidic electrophoresis (LabChip GXII), HPLC, DLS, LC-MS, GC, and Bradford and BCA assays. 
    • Extensive knowledge of CMC and regulatory requirements for biologics, including ICH Quality Guidelines and appropriate cGMP health authority guidelines and regulations (e.g., FDA, EMA, MHRA). 
    • Expert technical skills and experience with development, qualification, validation, and transfer of biophysical and biochemical analytical methods in a GLP/GxP environment to support process development, product characterization and release, and stability. 
    • Experience with LNP, mRNA or AAVs is highly desirable.  
    • Prior experience interacting with healthcare authorities, such as scientific advisory meetings, audits, and inspections. 
    • Experience with setting up new lab space, including instruments and equipment qualification. 
    • Self-motivated, detail-oriented, strong interpersonal skills and an ability to participate and work effectively on multiple cross-functional teams.  
    • You take initiative. Teams love working with you, and you are someone who takes pride in mentoring and supporting the careers of others.
