Job Title: Software Simulation Engineer

Job Description

This role offers the opportunity to design, develop, and integrate software for advanced flight simulators used to support a range of aircraft platforms. You will work across avionics, tactical environments, and interfaces to audio, visual, motion, and I/O systems, as well as Instructor Operator Stations (IOS). The position involves full lifecycle software engineering in both Linux and Windows environments using multiple programming languages, with a strong focus on simulation and modeling for complex, real-time systems.

Responsibilities

• Design, develop, and integrate software for flight simulators, including avionics, tactical environments, and interfaces to audio, visual, motion, and I/O systems.
• Implement and maintain software for Instructor Operator Stations (IOS) to support effective simulator operation and training.
• Support software development activities as assigned by the software lead, contributing to all phases of the project lifecycle, including requirements analysis, design, implementation, integration, and testing.
• Develop complex software applications such as interfaces to external systems and software simulations of aircraft systems with minimal supervision from the software lead.
• Design software architectures for components within larger systems, including software interfaces and models of aircraft components.
• Prepare clear and thorough software documentation, including design descriptions and inputs for formal design reviews.
• Participate in and present software designs at customer reviews, effectively communicating technical concepts to stakeholders.
• Collaborate closely with cross-functional team members to ensure integrated, high-quality simulation solutions.
• Provide guidance and informal mentorship to junior engineers, supporting their technical development and contributing to a collaborative team culture.
• Contribute to the continuous improvement of software engineering processes, tools, and practices within the team.

Essential Skills

• Bachelor’s degree in Engineering or Computer Science.
• At least 5 years of software engineering experience.
• Ability to develop software in multiple languages, including C and C++.
• Experience with FORTRAN or similar legacy languages used in simulation environments.
• Proficiency in C++ with a focus on simulation and modeling software.
• Proficiency using Visual Studio IDE for development and debugging.
• Proficiency with GCC compilers and Makefiles for building applications in Linux and UNIX environments.
• Strong experience working in Linux and UNIX environments, with familiarity in Windows development.
• Solid understanding of software engineering concepts and processes, including requirements analysis, design, implementation, testing, and documentation.
• Ability to work effectively in a team environment and collaborate with software leads and peers.
• Strong communication skills to interface with customers and present software designs.
• Eligibility to obtain a security clearance, with an active or prior Secret clearance preferred.

Additional Skills & Qualifications

• Knowledge of object-oriented design concepts and their application to complex software systems.
• Knowledge of flight simulation concepts and architectures.
• Experience with real-time programming and real-time operating constraints.
• Knowledge of military aircraft systems and avionics.
• Familiarity with networking concepts and protocols relevant to distributed simulation systems.
• Experience with interoperability standards such as HLA/DIS in modeling and simulation environments.
• Background in graphics or real-time embedded systems.
• Experience working on or supporting flight simulators for platforms such as MH-47G, V-22, MH-60M, AH-1Z, CH-53K, UH-1Y, or AH-60M.
• Experience participating in design and technical reviews with customers or external stakeholders.
• Ability to travel domestically and internationally as project needs require.
