Candidate can expect to work closely with a team of engineers and scientists to write software (using primarily C++ and Python) to solve problems in a variety of disciplines to include EO/IR sensor systems, primarily for modeling & simulation purposes.
Because the candidate may fill various project needs, an interest in working multiple programs with intermediate ability in C++ and Python is expected along with strong object-oriented design skills, the ability to create design documentation, requirements specifications, and other technical documentation.
Candidate is also expected to have the ability to work and to communicate effectively within a multidisciplinary team and have familiarity with software development for both Windows and Linux OS.

Intermediate ability with C++/Python and experience using version control systems such as Git.
Candidate must be a resident of the North Alabama area or willing to relocate to the Huntsville – North Alabama, AL, area.
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.
Preference may be given to candidates with one or more of the following: recent stellar academic performance, a TS/SCI clearance (with CI Polygraph); 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; experience with build systems such as CMake.
At Leidos, we don’t want someone who "fits the mold"—we want someone who melts it down and builds something better. This is a role for the restless, the over-caffeinated, the ones who ask, “what’s next?” before the dust settles on “what’s now.”
If you’re already scheming step 20 while everyone else is still debating step 2… good. You’ll fit right in.
For U.S. Positions: While subject to change based on business needs, Leidos reasonably anticipates that this job requisition will remain open for at least 3 days with an anticipated close date of no earlier than 3 days after the original posting date as listed above.

Additional factors considered in extending an offer include (but are not limited to) responsibilities of the job, education, experience, knowledge, skills, and abilities, as well as internal equity, alignment with market data, applicable bargaining agreement (if any), or other law.
