Senior Manufacturing Engineer

Senior Manufacturing Engineer Woburn & Allston, Massachusetts About Terrestrial Bio, Inc. Terrestrial is transforming the delivery of next-generation therapies, starting with GLP-1. Terrestrial's proprietary Tacterra™ microarray patch (MAP) and applicator platform consists of a patch resembling an adhesive bandage, which is applied with a preloaded applicator and removed after a few minutes. Once applied, each patch delivers bioactive tips into the skin, which dissolve quickly into the body, rapidly releasing their therapeutic payload. Designed for self-administration, the temperature-stable Tacterra™ platform enables precise, controlled delivery of a wide range of therapeutics without medical sharps or refrigeration. Terrestrial has generated strong clinical and in-vivo proof of concept across multiple molecules. For more information, visit At Terrestrial Bio, Manufacturing Engineering is not a support function. It is the technical foundation that transforms innovative product concepts into robust, compliant, and scalable manufacturing operations. The decisions made today will determine our ability to successfully transition from clinical manufacturing to commercial production while maintaining product quality, regulatory compliance, and operational excellence. We are building our manufacturing organization from the ground up. We need a highly experienced engineer who can independently lead complex technical initiatives, establish engineering best practices, and serve as a technical authority across manufacturing, validation, automation, and quality. The Senior Manufacturing Engineer III is a senior technical leader responsible for implementing and optimizing the manufacturing systems that will support Terrestrial Bio’s next phase of growth. This role will lead equipment integration, process validation, technology transfer, and continuous improvement initiatives while helping establish the engineering standards, documentation, and manufacturing processes that will support a highly automated manufacturing operation. This is not simply a production support role. It is a build role with significant technical ownership. The successful candidate will help design the manufacturing systems, engineering processes, and operational infrastructure that enable Terrestrial Bio to scale efficiently while maintaining compliance, product quality, and operational agility. What You Will Own You will establish the Manufacturing Engineering function from the ground up and play a critical role in carrying it through the company’s next phase of growth. That means: Lead technical implementation and integration of highly automated equipment and processes, including commissioning, qualification (IQ/OQ/PQ), technology transfer, and site expansion/startup activities. Develop manufacturing engineering standards, SOPs, equipment lifecycle documentation, and validation documentation to support a robust, compliant, and scalable operation. Establish cross-functional partnerships with Automation, Quality, Facilities, Process Development, and Manufacturing Operations; lead investigations, change controls, CAPAs, root cause analyses, and continuous improvement initiatives to improve reliability, yield, throughput, and OEE. Serve as a senior technical resource and mentor, collaborate with suppliers on FAT/SAT and startup, and support regulatory activities. Why This Role Is Compelling The Senior Manufacturing Engineer III is responsible for providing technical leadership and execution for manufacturing engineering activities supporting Phase 3 commercial manufacturing of a highly automated pharmaceutical-medical device combination product manufactured in ISO Class 5 isolator environments and reports to the Senior Director of Manufacturing Engineering. What Makes Someone a Strong Fit Experience with transfer, installation, startup, and integration of highly automated manufacturing systems, including custom automation and OEM equipment. Experience operating within Grade A/ISO Class 5 or aseptic/low bioburden manufacturing environments. Develop and execute qualification protocols including Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) for manufacturing equipment, facilities, utilities, and ancillary systems. Develop, review, and revise manufacturing engineering documentation including protocols, reports, work instructions, standard operating procedures (SOPs), engineering specifications, and equipment lifecycle documentation. Participate in cross-functional capital projects including equipment selection, vendor management, User Requirements (URS), Factory Acceptance Testing (FAT), Site Acceptance Testing (SAT), qualification protocols, validation reports, commissioning, and startup activities. Support implementation and lifecycle management of Manufacturing Execution Systems (MES), Electronic Batch Records (EBR), and equipment data acquisition systems Provide technical support for deviation investigations, nonconformances, CAPAs, change controls, and equipment troubleshooting using structured root cause analysis methodologies. Apply engineering principles and statistical methods to improve equipment reliability, process capability, throughput, yield, and Overall Equipment Effectiveness (OEE). Identify and implement continuous improvement initiatives to improve manufacturing robustness, efficiency, and product quality. Support scale-up activities from clinical manufacturing through commercial readiness while ensuring phase-appropriate GMP compliance. Evaluate manufacturing risks and recommend mitigation strategies utilizing Quality Risk Management principles. Mentor junior manufacturing engineers and engineering technicians by providing technical guidance, knowledge sharing, and project leadership. Experience and Background Core requirements Bachelor's degree in Mechanical Engineering, Chemical Engineering, Biomedical Engineering, Industrial Engineering, or related engineering discipline. Minimum 6+ years of manufacturing engineering experience in pharmaceutical, biotechnology, medical device, or combination product manufacturing. Demonstrated experience supporting Phase 2 and/or Phase 3 clinical manufacturing environments with combination products, polymer processing, and/or unique drug delivery technologies. Demonstrated experience independently leading cross-functional technical projects. Strong understanding of cGMP regulations and for pharmaceutical and/or combination product quality systems. Excellent analytical, troubleshooting, and structure problem-solving skills. Effective written and verbal communication skills with the ability to influence cross-functional teams. Preferred Experience supporting drug-device combination product manufacturing. Experience with isolator-based manufacturing systems and/or aseptic processes. Knowledge of 21 CFR Parts, 210, 211, 820, and Part 11 requirements. Strong understanding of validation lifecycle management and risk-based qualification strategies. Experience supporting implementation of Manufacturing Execution Systems (MES) and Electronic Batch Records (EBR). Lean Six Sigma Green Belt or Black Belt certification Experience supporting technology transfer from development through commercial manufacturing. What Success Looks Like Within 12–18 months: Highly automated manufacturing systems in place and qualified for GMP clinical production, ready for Phase 3 and commercial manufacturing. MES and EBR implemented and qualified with minimal issues. Engineering processes are place and establishes clear standards, documentation, SOPs, and equipment lifecycle practices to support compliant and scalable GMP operation. Respected as a trusted technical partner who works effectively with Quality, Automation, Facilities, and R&D. Improved manufacturing performance with increased equipment reliability, throughput, and OEE while reducing deviations and driving continuous improvement. This is a role for a senior leader who wants to build something durable — and lead it through scale. Compensation range $120,000 to $140,000
