Postdoctoral Appointee - Advanced Manufacturing

Sandia National Laboratories

Albuquerque, NM

Job posting number: #7072811 (Ref:674255)

Posted: December 4, 2020

Job Description

This posting will be open for application submissions for a minimum of seven (7) calendar days, including the ‘posting date’. Sandia reserves the right to extend the posting date at any time. : Passionate about advanced manufacturing and dream of utilizing state-of-the-art facilities to explore solutions? Check us out! Our team is seeking a Postdoctoral Appointee candidate to support research and development in the field of additive manufacturing and related processing of particulate inks and slurries for a variety of national security customers. The position will focus on printing materials formulation and characterization and the development and operation of printing processes for existing and new applications using the printing platforms at the AML (e.g. direct write, photopolymer lithography, etc.). This work will be highly multi-disciplinary requiring the Postdoc to be engaged in different types of solo and collaborative laboratory work, including the development and application of computational finite element models. You'll contribute to a number of projects and work effectively in a diverse research environment as a team member. On any given day you will be called on to: + Conduct fundamental research and development on direct-ink-write printing and coating using a variety of experimental and computational tools. + Work towards model validation and development of precision ink-based printing processes will be conducted on direct-ink-write printing and coating tools including ink-jet, aerosol-jet, and gravure/flexographic printers in the laboratory + Development and application of finite-element solid models and meshes for 2D and 3D solution of differential equations in complex geometries + Running simulations of coating and drying processes, and executing parametric studies targeted at model validation and prediction of coating trials/tests at partner sites + Characterizing new ink formulations in collaboration with chemists and materials scientists, characterizing them rheologically for printability and application of inks to printed and coating form factors using ink-jet, aerosol jet or wide-area gravure coating and drying The time-portion of job assignments associated with computational model and code-development will be about two-thirds. The Postdoc will be developing models for printing and coating using capillary hydrodynamics and associated particle-based rheology models in Goma 6.0 (a finite element open-source software developed primarily at Sandia National Laboratories, https://github.com/goma). Join our team and work towards your goals while making a difference!

Required:
+ Have, or are pursuing, a PhD in chemical or mechanical engineering, materials science or related science and engineering field + Proven track record in computer modeling and lab-level experimental activities + Outstanding interpersonal skills as evidenced by a proven track record of publication of results in peer-reviewed journals and external presentations at professional scientific conferences + Able to acquire and maintain a DOE Q-level security clearance

Desired:
+ Ability to work collaboratively in a team and a desire to ensure success of the team + Experience with solid model and mesh generation as it applies to finite-element model development and application + Demonstrated experience with computer programming with C, C++, Fortran or related MatLab tools. + Lab-level experimental experience with thin-liquid film development and application, with associated characterization using gravimetric, optical-microscopic, and other microscopy techniques + Domain-application experience in printing and coating applications, with associated capillary hydrodynamics and particulate-film drying processes

Department Description:

The Advanced Materials Laboratory conducts R&D in a wide range of novel materials synthesis strategies and novel processing techniques to advance scientific understanding and provide practical solutions to the needs of a wide variety of external and internal customers. Specifically, activities in our research groups include; synthesizing new precursor chemistries and surface functional groups, understanding different routes to nanoscale particles and thin films, understanding the rheology of metal-particle “inks” and ceramic slurries, investigating new catalyst materials and conducting mechanistic studies of catalysis, and investigating the self-assembly of nanoparticles in 2- and 3-dimensions. Processing R&D includes; providing a “Direct Write” capability that can deliver metal nanoparticle inks to topographically challenging substrates, electrospinning of fibers of vastly different compositions, and combining different materials and processing strategies for a variety of national security applications. Our customers include all of Sandia’s mission areas and numerous external collaborators. Our laboratory facilities are located at the Advanced Materials Laboratory, a leased facility on the campus of the University of New Mexico. This geographical advantage allows us to work closely with students and faculty at community colleges and UNM, as well as universities throughout the United States.

Security Clearance:

Sandia is required by DOE to conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Applicants for employment need to be able to obtain and maintain a DOE Q-level security clearance, which requires U.S. citizenship. If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain a security clearance may be impacted. Applicants offered employment with Sandia are subject to a federal background investigation to meet the requirements for access to classified information or matter if the duties of the position require a DOE security clearance. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause a clearance to be denied or terminated by DOE, resulting in the inability to perform the duties assigned and subsequent termination of employment.
