Business Segment
Healthcare Systems
About Us
The successful candidate will: Join the magnet/gradient engineering team, centered in Tianjin, China. Participate in all phases of the product development life cycle, from concept and product specification generation, to manufacturing ramp up and manufacturing production support, optimizing functionality, manufacturability, reliability, serviceability and cost. Be involved in both new product design and support of existing products with manufacturing, sourcing and service. Participate in product safety, cost out, cycle time reduction and quality enhancement projects. Support and comply with the quality and safety goals of GE Healthcare (GEHC). Define magnet, gradient coil and MRI system functional requirements and ensure product performance goals are met. Provide support and direction in the design and analysis of advanced products. Support the manufacturing plant and the Installed Base
Role Summary/Purpose

Essential Responsibilities
Thermal design and analysis of superconducting magnets and components used in MRI systems Thermodynamic and heat transfer analysis, including determination of heat loads, heat budgets and test verification. Thermal & Structural design of cryogenic components Verification and Validation of cryogenic components and instrumentation (eg. Valves, burst disks, Temperature sensors, cryocoolers, compressors, etc.) Reliability analysis of cryogenic components and systems Manufacturing support of cryogenic and vacuum systems Development of methods to reduce cryogen consumption Failure analysis of cryogenic components (eg. thermal shields, compressors, plumbing) Development of service tools to support cryogen filling, maintenance & safety of magnets Installed Base data analysis and reduction. Lead resolution of cryogenic, thermal and vacuum issues relating to Install Base Systems Maintain competitive advantage by staying current in state of the art in cryogenic technology and recommend/implement innovative changes to product design while justifying cost with well developed business cases Preparation/presentation of design analysis reports and part/assembly drawing reviews Develop product, component test and purchase specifications Design leadership of productivity projects (both product cost and life cycle cost reduction) Coordinate cross-functional design, analysis and testing. Support manufacturing lean initiatives Provide creative solutions to unstructured product and system design issues from both factory and field


Qualifications/Requirements
