  • Must be a U.S. citizen and able to obtain and maintain a DoW security clearance. 

 

Preferred Qualifications.  

  • In addition to the qualifications listed above, the ideal candidate should be highly organized, demonstrating the ability to work independently at times due to a fast-paced and highly productive work environment. Because the candidate may fill various project needs, an interest in working multiple programs with intermediate ability in C++, C#, and/or Python is a bonus. 

  • Preference may be given to candidates with one or more of the following: recent stellar academic performance in physics and/or engineering classes, a SECRET clearance or above; familiarity or interest in EO/IR phenomenology; experience with image processing; experience with GPU programming and/or CUDA programming; experience with developing AI/ML solutions. 

  

Come break things (in a good way). Then build them smarter.

We're the tech company everyone calls when things get weird. We don’t wear capes (they’re a safety hazard), but we do solve high-stakes problems with code, caffeine, and a healthy disregard for “how it’s always been done.”
