Applied Polymer Science - Research Scientist

Lawrence Livermore National Laboratory
Livermore, CA 94550

We have an opening for an Applied Polymer Scientist to conduct research in the following areas: I) research into the influence of age, environment, and manufacturing process conditions on the chemical structure and physical properties of engineering polymer materials; II) research and development of new engineering viscoelastomers, viscoelastomer resins, and high-crosslink-density structural polymers, including materials for production by additive manufacturing (AM). This position is in the Materials Science Division.

This position will be filled at the SES.3 or SES.4 level depending on your qualifications. Additional job responsibilities (outlined below) will be assigned if you are selected at the higher level.

In this role you will

  • Characterize the chemical changes and degradations to engineering polymer materials, especially silicones, resulting from age, environment, and manufacturing process conditions.
  • Collaborate on accelerated aging and lifetime prediction studies of engineering polymer materials.
  • Contribute to the research and development of new polymer materials ranging from rubbery viscoelastomers to thermosets, including development of candidate feedstocks for the additive manufacturing of engineering polymer materials, by such processes as direct-ink-write, fused-deposition modeling, selective laser sintering, or stereolithography.
  • Serve as a primary technical point of contact for polymer material formulation, synthesis and processing.
  • Conceive, design, and execute research to address defined problems and applications.
  • Develop and present written analyses, verbal briefings, and other products that capture and communicate research results as well as periodic progress reports.
  • Collaborate with scientists in a multidisciplinary team environment to accomplish program goals.
  • Document research; publish papers in peer-reviewed journals, and present results within the DOE community and at open conferences.
  • Perform other duties as assigned.

Additional job responsibilities at the SES.4 Level

  • Independently develop or lead development of new materials and/or feedstocks for additive manufacturing of engineering polymer materials.
  • Serve as a subject matter expert for polymer synthesis, processing, and characterization.
  • Serve as point of contact for accelerated aging and lifetime prediction studies of engineering polymer materials.

  • 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 or process synthesis of polymer resins for engineering applications (e.g. silicones, PEEK materials).
  • Significant experience with polymer resin characterization, including molecular weight distribution analysis, composition, and tacticity analysis for copolymers.
  • Significant experience with mechanical (and/or rheological) and structural characterization of both resin and polymer material properties, using, for example, techniques such as DMA, rotational rheometry, swelling, thermal analysis, and/or load frame testing.
  • Proven ability as a creative experimentalist, and a diverse range of experience in experimental design, techniques and execution.
  • Authorship of peer-reviewed literature demonstrating the capacity to independently develop and execute original research.
  • Advanced verbal and written communication as reflected by effective presentations at seminars, meetings and/or teaching lectures.
  • The willingness and ability to self-direct and work independently, and to collaborate on multidisciplinary teams as required to reach research goals.

Additional qualifications at the SES.4 Level

  • Highly advanced knowledge of polymer characterization, including, for example, monomer sequence distribution analysis in copolymers, or analysis of measured mechanical/rheological properties and their relationship to structure.
  • Subject matter expertise in the processing and/or rheology of filled (reinforced) polymer materials.
  • Consultative direction of scientific personnel and complex projects.

Qualification 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.

COVID-19 Vaccination Mandate

LLNL demonstrates its commitment to public safety by requiring that all new Laboratory employees be immunized against COVID-19 unless granted an accommodation under applicable state or federal law. This requirement will apply to all new hires including those who will be working on site, as well as those who will be teleworking.

Security Clearance

LLNL is a Department of Energy (DOE) and National Nuclear Security Administration (NNSA) Laboratory. Some positions will require a DOE L or Q clearance (please reference Security Clearance requirement above). If you are selected and a clearance is required, we will initiate a Federal background investigation to determine if you meet eligibility requirements for access to classified information or matter. In addition, all L or Q cleared employees are subject to random drug testing. An L or Q clearance requires U.S. citizenship. For additional information please see DOE Order 472.2.

Pre-Employment Drug Test

External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test. This includes testing for use of marijuana as Federal Law applies to us as a Federal Contractor.

Pre-Placement Medical Exam

A job related pre-placement medical examination may be required.
