JSE Lead API Developer

About the role

FlightSafety International is the world’s premier professional aviation training company and supplier of flight simulators, visual systems and displays to commercial, government and military organizations. The JSE Lead API Developer position 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

• Integrate software/simulation components that connect FlightSafety training devices to the JSE via the Global Reusable Interface Domain (GRID) network protocol.
• Implement message production and consumption logic using the Government Simulation Interface (GSI) Software Development Kit (SDK).
• Verify correct integration against the GSI Interface Control Document (ICD).
• Execute the GSI test harness suite of service active tests and support Wireshark packet capture (.pcap) file parsing to validate data flow between the simulator and GRID services.
• Support SCARS compliance activities, including applying On Premise Equipment (OPE) integration standards under the SCARS Architecture Standard, Increment 5, and contribute to verification activities for common aerodynamic models (Equations of Motion, Forces and Moments, and Mass Properties).
• Contribute to the implementation and operation of the internal JSE/SCARS integration lab — both virtual and classified, as required — and support DevSecOps pipeline activities for JSE/SCARS-related software deliverables, including version control, automated testing, and documentation in compliance with the SCARS DevSecOps Process Standard.
• Support the application of cybersecurity controls in accordance with the SCARS Common Security Controls Standard and coordinate with the cybersecurity team on Risk Management Framework (RMF) compliance activities.
• Work closely with the JSE/SCARS architects to interpret SCARS and JSE documentation, implement design patterns, and document integration results.

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.
• Hands-on experience with software development tools including GitLab, JIRA, and CI/CD pipeline environments.
• 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.
• Experience with common aerodynamic model development or verification (Equations of Motion, Forces and Moments, Mass Properties).
• Experience with RMF, ATO processes, or DoD cybersecurity compliance activities.
