Operations Engineer

We are looking for a hands-on Operations Engineer to support and scale manufacturing operations in a peptide API facility. This role will work closely with the Operations Manager to execute daily production, troubleshoot processes, and help build robust, GMP-compliant systems. The ideal candidate is technically strong, highly adaptable, and eager to take ownership in a fast-paced, developing environment operating within applicable regulatory frameworks.

You will:

  • Support daily peptide API manufacturing operations, including solid-phase peptide synthesis (SPPS), purification (HPLC), and lyophilization.
  • Troubleshoot manufacturing and process issues in real time to minimize downtime and maximize batch success.
  • Assist in the execution of production batches, including equipment setup, process monitoring, and batch documentation.
  • Analyze manufacturing performance, including yield, cycle time, and deviations, and implement process improvements to enhance efficiency and robustness.
  • Support process scale-up activities and technology transfers from R&D into commercial manufacturing.
  • Identify opportunities to optimize manufacturing processes, reduce waste, and improve operational performance.
  • Author and maintain SOPs, batch records, technical reports, and other GMP documentation.
  • Support deviation investigations, CAPAs, change controls, and continuous improvement initiatives.
  • Ensure accurate, timely, and compliant documentation in accordance with cGMP requirements.
  • Assist with equipment commissioning, qualification (IQ/OQ/PQ), calibration, preventive maintenance, and maintenance coordination.
  • Partner with Engineering to troubleshoot equipment issues and support equipment upgrades and reliability initiatives.
  • Collaborate closely with QA/QC to ensure product quality, regulatory compliance, and inspection readiness.
  • Operate within applicable, evolving regulatory frameworks
  • Support internal and external audits while adhering to all safety, environmental, and quality standards.
  • Partner cross-functionally with R&D, Engineering, Quality, and Supply Chain to ensure seamless manufacturing operations and successful introduction of new materials and processes.

You have:

  • Bachelor's degree in Chemical Engineering, Chemistry, Biochemistry, or a related scientific discipline.
  • 2+ years of experience in pharmaceutical, biotechnology, or chemical manufacturing.
  • Experience supporting peptide synthesis, API manufacturing, or similarly complex chemical manufacturing processes strongly preferred.
  • Prior experience working in a startup or other fast-paced, high-growth manufacturing environment is a plus.
  • Hands-on experience troubleshooting manufacturing processes and equipment in a production environment.
  • Strong understanding of chemical manufacturing principles with the ability and desire to learn peptide manufacturing processes.
  • Experience executing process improvements and translating technical plans into operational results.
  • Working knowledge of cGMP principles, including documentation, compliance, and quality systems.
  • Strong attention to detail with a commitment to maintaining accurate GMP documentation and high-quality standards.
  • Ability to adapt quickly to changing priorities and thrive in a dynamic, evolving environment.
  • Excellent collaboration and communication skills, with the ability to work effectively across Engineering, Manufacturing, Quality, R&D, and Supply Chain teams.
  • Willingness to work flexible hours as needed to support manufacturing operations and production schedules.
