Preferred Qualifications:Hands-on experience with industry-leading laser/ultrasonic welding systems (e.g., Coherent, IPG Photonics, TRUMPF, Branson, Evosys or equivalent; Branson, Herrmann, Dukane, Rinco, or equivalent) Experience with multiple laser/ultrasonic welding modalities (e.g., Nd:YAG, fiber laser, diode laser, CO2; standard ultrasonic, multi-frequency, continuous ultrasonic welding) Experience with laser transmission welding (LTW) for thermoplastic components; experience with hermetic sealing validation and leak testing methodologies Experience with alternative plastic joining technologies (e.g., laser welding, heat staking, vibration welding) for comparative process selection, hermetic sealing validation, weld inspection, horn and fixture design and acoustic stack optimization Experience supporting Contract Manufacturers in a medical device environment Familiarity with MES (Manufacturing Execution Systems) integration w/welding equipment Microsoft Office, Minitab, Document Management Systems, MES, AutoCAD, SolidWorks, SAP Responsibilities may include the following and other duties may be assigned. Designs manufacturing processes, procedures and production layouts for assemblies, equipment installation, processing, machining and material handling. Designs arrangement of machines within plant facilities to ensure most efficient and productive layout. Designs sequence of operations and specifies procedures for the fabrication of tools and equipment and other functions that affect product performance. Adapts machine or equipment design to factory and production conditions. May incorporate inspection and test requirements into the production plan. Inspects performance of machinery, equipment, and tools to verify their efficiency, and investigates and initiates corrective action of problems and deficiencies to ensure product quality. Develops manufacturing processes that are applicable to statistical process control, and may develop those techniques. Provides guidance to engineering regarding design concepts and specification requirements to best utilize equipment and manufacturing techniques. Ensures processes and procedures are in compliance with regulations. TECHNICAL SPECIALIST CAREER STREAM: An individual contributor with responsibility in our technical functions to advance existing technology or introduce new technology and therapies. Formulates, delivers and/or manages projects assigned and works with other stakeholders to achieve desired results. May act as a mentor to colleagues or may direct the work of other lower level professionals. The majority of time is spent delivering R&D, systems or initiatives related to new technologies or therapies – from design to implementation – while adhering to policies, using specialized knowledge and skills.
