Afternoon Simulation Software Engineer Jobs in Chicago, IL

Auria is looking to hire a Software or Systems Engineer to support the FSDS program. Federal Spectrum Data System (FSDS) modernizes the NTIA's spectrum management functions by eliminating or drastically reducing the required manual intervention to execute necessary tasks. The new system will manage a large amount of spectrum‑dependent data, analytic engineering analyses & tools, spectrum management processes and workflows, and AI enhancements of all of the above. The solution requires data integration across multiple diverse sources, several of which exist outside the scope of FSDS and therefore require novel solutions to ensure secure, efficient, and effective data exchange. This modernization effort will require advanced understanding of spectrum management, RF modeling, and some legacy spectrum‑related systems, processes, and workflows. This will represent a large effort to overcome the problems the NTIA currently faces with disconnected and incomplete siloed tools and systems, by creating a massive spectrum management system that manages federal spectrum resources, demands, and needs in a world with increasingly advanced and complex systems operating in a similarly complex and congested spectral environment.

• Write C++, NodeJS, and Python code
• Develop, improve, and debug advanced RF modelling and simulation algorithms
• Communicate technical matters related to those RF models and simulations to the customer
• Proficiently use or interact with DevSecOps tools like package managers, content registries, dev pipelines, web servers, etc.

• A degree in, or related to, the fields of electrical engineering, physics, mathematics, computer engineering, and/or software development
• 3+ years of work or otherwise demonstrable experience in at least one of the fields listed above
• Demonstrable understanding in one of: electromagnetics, radio Tx/Rx component‑specific modelling (including radars, GNSS, and SATCOM), and wireless communications fundamentals
• Demonstrable command of C++
• Demonstrable command of industry‑standard C++ development practices, such as version control, unit/integration/automated testing, and peer programming and code review processes

• Secret or higher Clearance
• A Master’s or Doctorate in a related field (see Minimum Qualifications) is preferred
• Demonstrable understanding in one of: spectrum resource management & optimization, signal processing, statistics, stochastics, and frequency domain analysis
• Demonstrable command of Python, JS, or other similar programming languages
• Demonstrable command of industry‑standard CI/CD DevSecOps practices to include pipeline management, build toolchain setup, and CI/CD automation

The salary offered will be based on the selected candidate’s qualifications - skills, education & experience - and the position level. $100,000 - $150,000
