We have an opening for a Polymer R&D Scientist/Engineer to conduct activities in support of the surveillance enterprise and aging assessments for polymeric parts and materials, work as a subject matter expert (SME) in general polymer science, for issues such as polymer chemistry, characterization, processing, and mechanical properties, and activities in support of the timely and accurate manufacturing of polymeric parts. This position is in the Materials Science Division.
- Characterize the chemical changes and degradations to engineering polymer materials, especially silicones, resulting from age, environment, and manufacturing process conditions.
- Serve as a primary technical point of contact for polymer material formulation, synthesis and processing for engineering applications.
- Participate in and provide guidance to accelerated aging and lifetime prediction activities of engineering polymer materials, including analysis of the causes of uncertainty and variance in polymer aging data.
- Participate in the management of scheduled production of polymer parts and to the assessment of the results of surveillance of such parts already in service.
- Collaborate in the development and revision of material and part requirements for various applications.
- Collaborate with scientists and engineers in a multidisciplinary team environment to accomplish program goals.
- Document research; document production processes and changes to production; publish papers in peer-reviewed journals, and report results to site system program management and the larger programmatic community within the DOE.
- Perform other duties as assigned.
- Ability to secure and maintain a U.S. DOE Q-level security clearance, which requires U.S. Citizenship.
- PhD in Polymer Science, Polymer Engineering, Materials Science, Materials Engineering, Chemistry, or related field, or the equivalent combination of education and related experience.
- Advanced knowledge of the synthesis of polymer resins, in particular elastomer and thermoplastic elastomer resins, for engineering applications (e.g. silicones, nitriles, TPU).
- Advanced knowledge of structural characterization of both resins and polymer networks using techniques such as thermal analysis, swelling, spectroscopic methods, or similar.
- Significant experience with mechanical and/or rheological characterization both resin and polymer material properties, using, for example, techniques such as DMA, rotational rheometry, and/or load frame testing.
- Significant experience with polymer industrial production and processing methods, including scale up methods.
- In depth knowledge of development requirements/standards for part production, mechanical drawings, and production quality control, and careful documentation of same.
- Authorship of peer-reviewed literature demonstrating the capacity to independently develop and execute original research.
- Advanced verbal and written communication skills.
- Ability and willingness to self-direct and work independently, and to collaborate on multidisciplinary teams as required to reach research goals.
Qualifications We Desire
- Experience with polymer material additive manufacturing (AM), including synthesis of AM feedstock materials and/or actual AM fabrication processes.
- Experience with commercial gumstock and composite preparation processes such as roll mixing, intensive shear mixing, and/or extrusion.
- Knowledge of LLNL site and partner business practices and/or experience interfacing with same.
- Knowledge of one or more program sponsors and experience interfacing with same.
