Position Summary
Cambrex Snapdragon Boston is currently seeking exceptional candidates for its
Principal Scientist / Principal Engineer – Peptide Manufacturing
position at its Waltham, MA R&D center. A successful candidate will be joining a group of innovative and entrepreneurial engineers and scientists to enable the delivery of high quality, complex chemical matter to our clients.
We are seeking a highly experienced and innovative Principal Scientist or Principal Engineer with deep expertise in peptide synthesis and manufacturing to lead the development, scale-up, and commercialization of peptide-based drug substances. This role will be pivotal in bridging R&D and GMP manufacturing, optimizing synthetic strategies, and ensuring robust, compliant, and efficient peptide production processes.
Responsibilities
Lead process development and scale-up of peptide synthesis, including solid-phase peptide synthesis (SPPS), solution-phase synthesis, cleavage, purification, and lyophilization.
Design and execute DOE studies to optimize reaction conditions, resin loading, coupling strategies, and purification and isolation methods (e.g., RP-HPLC, IEC, TFF, lyophilization).
Evaluate and select appropriate resins, reagents, and solvents for phase-appropriate manufacturing.
Partner with analytical development to define and control critical quality attributes (CQAs) and critical process parameters (CPPs).
Lead tech transfer of peptide processes to internal or external GMP manufacturing sites; serve as technical SME during manufacturing campaigns.
Author and review process development reports, batch records, validation protocols, CMC documentation (e.g., Module 3), and regulatory filings (IND, NDA).
Collaborate cross-functionally with QA, QC, regulatory, and supply chain to ensure technical alignment and compliance.
Troubleshoot scale-up issues, support deviation investigations, and lead process improvements based on data-driven risk assessments.
Mentor junior scientists and engineers; contribute to building peptide capabilities and infrastructure.
Qualifications
Required Experience and Skills:
Expertise in SPPS instrumentation (e.g., CEM, Biotage, CS Bio, Liberty Blue) and downstream peptide purification.
Proven experience with GMP manufacturing and tech transfer of peptide APIs.
Strong understanding of regulatory guidelines (ICH Q8/Q9/Q11, FDA/EMA expectations) and process validation.
Familiarity with quality risk management, ICH M4/CTD, and QbD principles.
Excellent problem-solving, communication, and project leadership skills.
Understanding of quality control testing, specifications, and GMP documentation requirements.
Proficiency in analytical method development and interpretation, with working knowledge of HPLC, LC-MS, and other relevant techniques for peptide characterization.
Prior experience in a CDMO or biopharma setting strongly preferred.
Preferred Skills:
Experience with cyclic peptides, conjugates (e.g., PEGylated, lipidated peptides), or complex synthetic intermediates.
Working knowledge of Peptide-Drug Conjugates (PDCs) or hybrid synthesis technologies.
Familiarity with automation platforms and digital process monitoring tools.
Why Join Us
Innovative science and cutting-edge facilities
Collaborative and growth-oriented culture
Opportunity to make a global impact in therapeutic development
Education, Experience & Licensing Education :
PhD. in Organic Chemistry, Chemical Engineering, Pharmaceutical Sciences, or related field, with 5–8+ years of peptide manufacturing experience; or MS/BS with 10+ years in peptide process development or GMP manufacturing.
Cambrex is committed to providing a safe and productive work environment. All offers of employment are contingent on the successful completion of a comprehensive pre-employment screen. The pre-employment screen may consist of several components including but not limited to a drug test, criminal record check, identity verification, reference checks, education and employment verification, and may vary based on federal, state, and local laws. Refusal to submit to testing will result in disqualification of further employment consideration.
All requirements are subject to possible modifications to reasonably accommodate individuals with disabilities.
