Intern - Applied Combustion Research Department, R&D Undergrad Year Round


We are looking for a Intern - Applied Combustion Research Department, R&D Undergrad Year Round

Our Applied Combustion Research Department is looking for an intern to help advance DFI technology. The successful candidate will be part of the team conducting research in our optical-engine laboratory, which is focused on providing a fundamental understanding of how DFI works, with the ultimate goal being to move this promising technology into production applications.

Given their many desirable attributes, diesel engines are employed almost exclusively in heavy-duty applications around the world. Nevertheless, they produce emissions of soot, nitrogen oxides (NOx), and carbon dioxide (CO2). Soot and NOx are toxic, and CO2 and soot are the two most important climate-forcing species, so all these emissions must be minimized. Ducted fuel injection (DFI) is a technology that dramatically curtails soot emissions from diesel engines, which in turn enables NOx emissions to be mitigated more simply and cost-effectively using exhaust-gas recirculation (EGR). Research has shown that DFI is synergistic with sustainable fuels, enabling even larger soot reductions than the already substantial soot reductions enabled by DFI. Hence, DFI with EGR and sustainable fuels is a compelling approach for "difficult-to-electrify" heavy-duty applications.

Interns in our department on any given day may be called on to:

Design, fabrication, installation, and testing of components for optically accessible research facilities and laboratory infrastructure

Develop and/or maintain data-acquisition systems and data processing codes

Develop and/or maintain instrumentation and control systems for temperature, pressure, and flow

Develop/apply image processing codes for engineering/scientific data analysis

Participate in research projects, potentially leading to technical publications

This position offers substantial opportunity for technical mentorship.


You bring the confidence and skills to be eligible for the job by meeting these minimum requirements:

Currently attending and enrolled full time in an accredited undergraduate program

Pursuing a science, engineering, or math major

Minimum cumulative GPA of 3.0/4.0

Ability to work up to 25 hours per week during the academic year, and up to 40 hours per week during the summer

Are currently authorized or will be able to obtain authorization to work lawfully in the United States for Sandia National Laboratories


Well-developed organizational abilities and attention to detail

Excellent analytical and mathematical aptitude

Ability to learn new skills and desire to take on challenging assignments

Effective communication and ability to work with a team

Familiarity with 3D CAD programs such as Solidworks or Creo

Familiarity with programming languages such as MATLAB and/or Python

Familiarity with any of the following: hand/power tools, auto mechanics, plumbing, or general construction/fabrication

Ability to work either remotely or on-site during the academic year


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.


The mission of Sandia/California's Applied Combustion Research Department is to develop the science base needed by industry to build and optimize a new generation of advanced, high-efficiency, clean internal-combustion (IC) engines that use both conventional and alternative fuels. The department is part of Sandia's Combustion Research Facility (CRF), where ~100 scientists, engineers, and technologists conduct basic and applied research to improve our nation's ability to use and control combustion processes efficiently and cleanly. The CRF offers a challenging and stimulating work environment that addresses today's most critical energy and environmental issues, as well as opportunities for personal, professional, and technical growth.


Sandia National Laboratories is the nation’s premier science and engineering lab for national security and technology innovation, with teams of specialists focused on cutting-edge work in a broad array of areas. Some of the main reasons we love our jobs:

Challenging work with amazing impact that contributes to security, peace, and freedom worldwide

Extraordinary co-workers

Some of the best tools, equipment, and research facilities in the world

Career advancement and enrichment opportunities

Flexible work arrangements for many positions include 9/80 (work 80 hours every two weeks, with every other Friday off) and 4/10 (work 4 ten-hour days each week) compressed workweeks, part-time work, and telecommuting (a mix of onsite work and working from home)

Generous vacations, strong medical and other benefits, competitive 401k, learning opportunities, relocation assistance and amenities aimed at creating a solid work/life balance*

This position does not currently require a Department of Energy (DOE) security clearance.

Sandia will conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Furthermore, employees in New Mexico need to pass a U.S. Air Force background screen for access to Kirtland Air Force Base. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause access to be denied or terminated, resulting in the inability to perform the duties assigned and subsequent termination of employment.

If hired without a clearance and it subsequently becomes necessary to obtain and maintain one for the position, or you bid on positions that require a clearance, a pre-processing background review may be conducted prior to a required federal background investigation. Applicants for a DOE security clearance need to be U.S. citizens. 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.

Members of the workforce (MOWs) hired at Sandia who require uncleared access for greater than 179 days during their employment, are required to go through the Uncleared Personal Identity Verification (UPIV) process. Access includes physical and/or cyber (logical) access, as well as remote access to any NNSA information technology (IT) systems. UPIV requirements are not applicable to individuals who require a DOE personnel security clearance for the performance of their SNL employment or to foreign nationals. The UPIV process will include the completion of a USAccess Enrollment, SF-85 (Questionnaire for Non-Sensitive Positions) and OF-306 (Declaration of for Federal Employment). An unfavorable UPIV determination will result in immediate retrieval of the SNL issued badge, removal of cyber (logical) access and/or removal from SNL subcontract. All MOWs may appeal the unfavorable UPIV determination to DOE/NNSA immediately. If the appeal is unsuccessful, the MOW may try to go through the UPIV process one year after the decision date.


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.
