Postdoctoral Appointee - Impact in Granular Materials, Onsite

Bidder Eligibility This postdoctoral position is a temporary position for up to one year, which may be renewed at Sandia's discretion up to five additional years. The PhD must have been conferred within five years prior to employment. Individuals in postdoctoral positions may bid on regular Sandia positions as internal candidates, and in some cases may be converted to regular career positions during their term if warranted by ongoing operational needs, continuing availability of funds, and satisfactory job performance. Employees, excluding student interns, must remain in their current position for one year from their hire date before bidding on a new job. However, the hiring manager may obtain approval to consider a candidate before the one-year requirement is met via the review process. This approval must be secured prior to being interviewed for a posted position. The application of this requirement will not supersede collective bargaining agreements. Please refer to the collective bargaining labor agreements for eligibility requirements for represented bidders.
