• Develop enhancements, resolve defects, and optimize FIAB software performance within distributed or real‑time simulation architectures.
• Integrate FIAB capabilities with other JSE and non‑JSE platforms across synthetic training and test environments.
• Assist with accurately documenting, reporting, and tracking deficiencies related to FIAB and JPP components.
• Collaborate with Government stakeholders, pilots, and mission‑systems SMEs to support reliable, high‑fidelity synthetic testing and training capability.

• Professional experience supporting or integrating 5th‑generation fighter mission systems, avionics, sensor fusion, LO behaviors, or synthetic environment representations (F‑22 and/or F‑35).
• Experience integrating complex software systems or simulation components in distributed or real‑time environments.
• Ability to modify, debug, and troubleshoot C++ and/or Python source code within simulation frameworks.
• Experience working with software interfaces, middleware, plug‑ins, APIs, or data models used to connect simulation components.
• Proficiency working in a Linux command‑line environment.
• Strong communication, documentation, presentation, and interpersonal skills.
• Demonstrated strong work ethic and initiative to troubleshoot, address, and prevent problems on complex technical systems.
• Current or active Top Secret clearance within the last 24 months.
• Ability to obtain and maintain TS/SCI and SAP/SAR clearances.
