What Your Job Will Be Like:
As an R&D S&E Mechanical Engineer, you will apply integrated technical judgment grounded in the scientific method to identify and solve complex problems. You will collect and analyze data through observation and experimentation, formulate and test hypotheses, and innovate solutions that support Sandia National Laboratories¿ critical missions. Your work will be rooted in fundamental science and engineering principles, applying scientific theories and engineering methods to develop and demonstrate new designs, materials, products, and systems.
You will engage in both physical and computational simulation, analysis, and evaluation as core parts of your development process. Your responsibilities will span fundamental research, development, and demonstration activities within Sandia¿s science and engineering programs.
Key responsibilities include:
- Developing high-performance computational models to analyze mechanical and physical systems.
- Designing and implementing experimental diagnostic methods to measure mechanical and physical processes.
- Conducting research in areas such as engineering mechanics, fluid dynamics, thermodynamics, vibration, physical metallurgy, tribology, power engineering, kinematics, and heat transfer.
- Applying research findings to the design, development, analysis, and testing of mechanical, electromechanical, and piezoelectric systems, instruments, controls, engines, and machines.
- Analyzing system performance under stress conditions such as temperature, load, motion, shock, and vibration to ensure design requirements are met.
- Leading hands-on assembly, testing, and fielding of the products you design, working closely with skilled technicians in lab and environmental testing environments.
- Collaborating within integrated teams, fostering cross-capability mentoring, and supporting an experimentalist mindset.
- Participating in field missions to deploy and qualify technologies for their intended use.
This role offers a unique blend of cutting-edge R&D engineering and practical, hands-on involvement, providing exposure to both laboratory and field environments. You will have the opportunity to see your designs through from concept to real-world application, making a tangible impact on national security and scientific advancement.

Security Clearance:
Position requires a Department of Energy (DOE) Q security clearance to start, or equivalent active security clearance with another U.S. government agency (e.g., DOD). Sandia is required by DOE directive 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 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.
NNSA Requirements for MedPEDs:
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.
