Senior Software Engineer Full-Time | Tulsa, OK (Onsite) U.S. Citizenship Required Opportunity Overview We're partnering with an established engineering and simulation technology company developing advanced training and simulation systems used in aerospace, defense, and mission-critical environments. We are seeking a Senior Software Engineer with strong C/C++ development experience who enjoys solving complex technical challenges, designing software architectures, and working on sophisticated real-time simulation platforms. This role combines hands-on software development, system integration, and technical leadership within a highly collaborative engineering environment. The ideal candidate has experience developing software for simulation systems, training devices, embedded systems, aerospace applications, defense programs, or other real-time deterministic environments. Candidates with Linux experience and exposure to legacy simulation architectures written in C, C++, Ada, or Fortran will be especially attractive. What You'll Do • Lead software development efforts for advanced simulation and training systems. • Design, develop, test, and maintain software applications primarily using C and C++. • Analyze system requirements and translate them into robust software architectures and technical designs. • Develop software solutions that support real-time, deterministic, and high-performance simulation environments. • Define and support hardware/software integration requirements. • Conduct technical trade studies and evaluate alternative implementation approaches. • Collaborate closely with systems, hardware, networking, and manufacturing teams. • Troubleshoot and resolve complex software, integration, and performance issues. • Participate in software verification, validation, and acceptance testing activities. • Support deployment, installation, and customer acceptance events. • Produce technical documentation including software designs, interface specifications, test procedures, and status reports. • Contribute to proposal efforts and future technology initiatives. Technical Leadership Responsibilities While this role does not include direct personnel management, it carries significant technical leadership responsibilities, including: • Mentoring junior and mid-level engineers. • Conducting code reviews and technical peer reviews. • Promoting software engineering best practices. • Supporting onboarding and knowledge transfer efforts. • Driving process improvements and technical excellence. • Assisting project leadership with technical planning and risk assessment. • Facilitating collaboration across multidisciplinary engineering teams. Required Qualifications • Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, Physics, Mathematics, or a related technical discipline. • 4+ years of software engineering experience. • Strong development experience using C and/or C++. • Experience developing software in Linux environments. • Understanding of software architecture and object-oriented design principles. • Experience with software integration, debugging, and testing. • Experience using Git, Subversion, or similar version control systems. • Knowledge of networking concepts and computer architectures. • Strong troubleshooting and analytical skills. • Excellent communication and technical documentation abilities. Highly Desired Experience Candidates with experience in the following environments should be prioritized: • Simulation and training systems • Flight simulators • Aerospace software • Defense systems • Mission systems • Embedded systems • Real-time systems • Distributed systems • Hardware-in-the-loop (HIL) • Software-in-the-loop (SIL) • Deterministic computing environments Preferred Technical Experience Programming Languages • C • C++ • Ada • Fortran • Python • C# Operating Systems • Linux • RHEL • Ubuntu • CentOS • Unix Technical Areas • Real-time software development • Deterministic software execution • Simulator architecture • Software/hardware integration • Networked simulation systems • Performance optimization • Multi-threaded applications • Distributed computing systems What Makes Someone Stand Out The best candidates often come from environments where software must perform predictably and consistently under real-world conditions. Examples include: • Flight training simulators • Military simulation programs • Embedded aerospace systems • Avionics software • Defense platforms • Mission planning systems • Industrial control systems • Real-time visualization systems Experience with older simulator architectures that incorporate C++, Ada, Fortran, and Linux is particularly valuable.
