• Use Agile project management tools such as Jira to track work, manage tasks, and report progress to stakeholders.

• Contribute to and support space and missile defense–related capabilities, including space operations, orbital warfare, electronic warfare, and command and control functions, as they relate to training and simulation.

• Support the application of digital engineering principles, leveraging digital models and data throughout the lifecycle of complex systems where applicable.

• Collaborate with cloud engineering teams when using Amazon Web Services (AWS) or GovCloud environments to deploy and operate solutions.

• Participate in code reviews, technical discussions, and continuous improvement initiatives to enhance team performance and product quality.

Essential Skills

• Bachelor’s degree in computer science, engineering, or a related field from an accredited university.

• 15–20 years of experience in software engineering.

• Significant experience in at least one of the following areas: Modeling and Simulation, 3D Data Visualization, or Systems Integration and Test.

• Modeling and Simulation experience with platforms and tools such as STK and AFSIM, including their test and integration into software applications.

• Expertise in 3D data visualization with whole‑earth applications such as Cesium, STK, ArcGIS, or Unity, including visualization techniques for GIS, gaming, or simulation purposes.

• Strong background in planning, performing, and testing diverse system integrations through public APIs such as REST and ASP.NET, or via C#/C++ assemblies and DLLs.

• A minimum of 10 years of proven experience in a leadership role within an Agile Scrum environment, especially as a Scrum Master or Product Owner.
