We are seeking a highly motivated and experienced DevOps developer for our dynamic Computation Simulation (CompSim) DevOps team. Software Engineers work closely with research staff and code development teams in creating and managing applications to support modeling and simulation (ModSim) computational code suites. This position offers the opportunity to improve the stability, productivity, and security of software, to address performance challenges of existing software on emerging next generation platforms, and to guide researchers and code development teams toward better software engineering practices.

This role requires a strong understanding of both software development and IT operations, as well as the ability to effectively participate in cross-functional teams delivering high-quality products and services.

On any given day, you may be called on to:

Help research, conceive, and improve strategies for high-performance parallel algorithms.
Collaborate with colleagues across application-to-hardware domains.
Develop and test high quality software; detect, diagnose, and resolve software bugs.
Incorporate DevOps best practices for continuous integration and delivery.
Learn how to optimize software and algorithms on powerful testbed computers and supercomputers at Sandia and other DOE facilities and apply that knowledge.
Learn new programming languages, paradigms, and APIs relevant to High-Performance Computing (HPC) environments.
Collaborate with engineers, mathematicians, scientists, and other scientific programmers across diverse fields.
Engage in agile ceremonies, including sprint planning, stakeholder reviews, daily stand-ups, and retrospectives.

The selected applicant can be a virtual worker located in any U.S. State or District of Columbia. Regular or periodic travel to your assigned work location may be required.

The Enabling Capabilities for Modeling and Simulation Department (1448) within the Center for Computing Research, offers an array of talent and competencies that help ensure the success of the NNSA Advanced Simulation & Computing (ASC) Programs physics-based modeling and simulation capabilities. From DevOps to User Experience (UX) Research, Scrum Masters, Product Owners and Embedded Analysts, staff in this department work directly with code development teams and end users to ensure the performance and value of ModSim capabilities are realized. A key element of the work is teaming with application and algorithm developers to establish a solid foundation in software methodologies, innovative practices, and maintenance and support for production codes and libraries. The department works closely with other organizations across Sandia and with external collaborators.

This posting will be open for application submissions for a minimum of three (3) calendar days, including the 'posting date'. Sandia reserves the right to extend the posting date at any time.

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.

All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, or veteran status and any other protected class under state or federal law.

If you have a Medical Portable Electronic Device (MedPED), such as a pacemaker, defibrillator, drug-releasing pump, hearing aids, or diagnostic equipment and other equipment for measuring, monitoring, and recording body functions such as heartbeat and brain waves, if employed by Sandia National Laboratories you may be required to comply with NNSA security requirements for MedPEDs.

If you have a MedPED and you are selected for an on-site interview at Sandia National Laboratories, there may be additional steps necessary to ensure compliance with NNSA security requirements prior to the interview date.
