Position Overview

FlightSafety Defense Corporation is gearing to become a recognized integration partner and solution provider for the U.S. Air Force and U.S. Navy in the Joint Simulation Environment (JSE) and Simulator Common Architecture Requirements and Standards (SCARS) ecosystem. The JSE Lead API Developer is a key hands-on contributor within the JSE/SCARS line of efforts, working under the guidance of the JSE Architect and Project Lead to implement, test, and verify JSE/SCARS-compliant software and interfaces across FlightSafety's Weapon System Trainer (WST) and Training Systems portfolio. This role is well suited for a developer with a solid foundation in simulation software development who is ready to deepen their expertise in government simulation standards and distributed synthetic environments.

Key Responsibilities

The JSE Lead API Developer integrates software/simulation components that connect FlightSafety training devices to the JSE via the Global Reusable Interface Domain (GRID) network protocol. This includes implementing message production and consumption logic using the Government Simulation Interface (GSI) Software Development Kit (SDK), and verifying correct integration against the GSI Interface Control Document (ICD). The developer executes the GSI test harness suite of service active tests and supports Wireshark packet capture (.pcap) file parsing to validate data flow between the simulator and GRID services.

The developer supports SCARS compliance activities, including applying On Premise Equipment (OPE) integration standards under the SCARS Architecture Standard, Increment 5, and contributing to verification activities for common aerodynamic models (Equations of Motion, Forces and Moments, and Mass Properties). The developer participates in Requirements Verification Report (RVR) activities and maintains traceability between implementation work and Interface Control Documents (ICDs) and Interface Design Documents (IDDs).

The JSE Lead API Developer contributes to the implementation and operation of the internal JSE/SCARS integration lab — both virtual and classified, as required — and supports DevSecOps pipeline activities for JSE/SCARS-related software deliverables, including version control, automated testing, and documentation in compliance with the SCARS DevSecOps Process Standard. The developer also supports the application of cybersecurity controls in accordance with the SCARS Common Security Controls Standard and coordinates with the cybersecurity team on Risk Management Framework (RMF) compliance activities.

The developer works closely with the JSE/SCARS architects to interpret SCARS and JSE documentation, implement design patterns, and document integration results.

Travel to government test events is anticipated throughout the year.

Required Qualifications

• Bachelor's degree in computer science, systems engineering, electrical engineering, aerospace engineering, or a closely related technical discipline. Masters preferred.
• 4 to 8 years of experience in simulation software development, system integration, or distributed systems engineering, preferably in a DoD training or defense context
• Proficiency in C++ and Python for simulation software development and integration in a federated simulation environment
• Familiarity with distributed simulation protocols (HLA, DIS, or TENA) and API-driven software architectures using middlewares such as EMQX, DDS or Apache Kafka
• Experience working with interface control documents (ICDs), interface design documents (IDDs), or similar technical specifications
• Hands-on experience with software development tools including GitLab, JIRA, and CI/CD pipeline environments
• Ability to interpret technical standards and translate requirements into software implementations
• Strong written communication skills with ability to produce test reports, integration documentation, and compliance artifacts
• Familiarity with MBSE methodologies or SysML-based tools (e.g., Cameo Systems Modeler)
• Experience with virtualization technologies and containerized deployment environments
• Active Secret clearance

Preferred Qualifications

• Experience with JSE, SCARS, GRID, or related government simulation frameworks and standards
• Familiarity with the GSI Software Development Kit (SDK) and GSI test harness
• Exposure to SCARS Increment 5 standards
• Experience with common aerodynamic model development or verification (Equations of Motion, Forces and Moments, Mass Properties)
• Exposure to RMF, ATO processes, or DoD cybersecurity compliance activities

Why This Role

The JSE/SCARS line of efforts represents one of FlightSafety Defense Corporation's most strategically important investments in defense training systems. As a JSE Lead API Developer, you will work at the technical frontier of government synthetic environment standards, gaining hands-on experience with the architectures, protocols, and standards that define the next generation of joint warfighter training. You will be mentored by senior architects and positioned for growth as FSI Defense scales its portfolio across the USAF and Navy.
