Senior Mechanical Engineering Tech I

MaxCyte is seeking a Senior Mechanical Engineer I/II to develop innovative single-use fluid control assemblies and supporting instrumentation for next-generation life sciences technologies. In this role, you will define and lead the mechanical design strategy for single-use consumables and associated instrumentation ensuring robust closed-system performance aligned with GMP manufacturing requirements. You will own the mechanical development across the full product lifecyclefrom early concept and feasibility through detailed design, verification and validation, commercialization, and sustaining engineeringwhile collaborating closely with other engineers and cross-functional teams to integrate seamlessly with other subsystems. Together, you will deliver solutions that meet the highest standards for performance, reliability, and manufacturability.
Mechanical Design & Development: Lead mechanical design and development of integrated hardware and consumable subsystems for GMP manufacturing. Create CAD models & detailed drawings, specifications, BOMs, and ECOs. Perform tolerance analyses and FEA. Drive prototype builds, engineering testing, and failure/root-cause analysis. Design and develop bioprocess consumables and systems that support closed, sterile, single-use processing in GMP manufacturing environments, including fluid circuits, interfaces, and integrated fluid and thermal control components such as pumps, valves, heaters, and sensors. Apply biocompatible material selection and mechanical design principles to ensure reliable performance while meeting biological process requirements. Support system-level testing for functionality, performance, and robustness.
Document test methods and verification results. Collaboration: Collaborate with other technical disciplines and quality teams. Ensure Process Excellence: Champion adherence to engineering processes, safety requirements, and industry best practices. S. in Mechanical Engineering required; Experience: 5+ years of relevant experience in mechanical design in life science consumable, medical device, pharma, bioprocess components, or other regulated product development environments. Direct experience designing single-use consumables and fluid control assemblies for cell therapy, gene therapy, bioprocessing, or sterile fluid handling systems. Experience designing bioprocessing technologies such bioreactors, gas exchange, filtration, centrifugation, cell isolation, purification, process analytics, etc.
