Job Description

Job ID: 307969
Full/Part Time: Full-Time
Regular/Temporary: Temporary

Job Description

The Applied Materials & Performance group at the Pacific Northwest National Laboratory is seeking a post-doctoral research associate to contribute to the development and application of advanced processes in the area of friction stir welding, friction extrusion, and other high-shear thermomechanical approaches. This position will support business lines associated with the next generation of lightweight vehicles and other markets where improvements in structural performance and energy efficiency are of interest to the Department of Energy, Department of Defense, and industrial clients.

The position will require interaction on a daily basis with project managers, scientists, and engineers with a diversity of technical backgrounds. The research associate will be expected, with limited supervision, to execute task assignments, report regularly on progress, and will also be responsible for developing their own ideas and implementing solutions. This position is an excellent opportunity for the proactive scientist or engineer who desires to build technical expertise while making significant technical contributions to real-world metal joining and high-shear thermomechanical processing challenges.

The successful candidate will have a strong background in mechanical engineering, materials science, or metallurgy and the ability to assess and apply analytical results for designing and conducting experiments. The selected candidate will have the opportunity to work on projects where novel processes and controls are needed for joining dissimilar metals via friction stir welding and consolidating/extruding materials via friction extrusion. In addition, the selected candidate will have opportunities to propose original ideas and technical suggestions to senior project research staff and project managers to solve science and engineering problems.
