Software Engineer Sr - E3

Software EngineerBuild high-fidelity simulations that power next-generation sensor fusion systems. As a Software Engineer on the Fusion Simulation team, you will develop and integrate advanced simulation environments used to validate and test mission-critical fusion capabilities. Your work ensures that complex third-party models and internally developed algorithms perform accurately, efficiently, and reliably before deployment to operational systems. This role sits at the intersection of software engineering, modeling & simulation, and sensor fusion testing infrastructure. You will work in C++ to build scalable simulation components, integrate external models, and improve the fidelity of testing environments that directly support the development of advanced aerospace fusion systems.What You Will Be Doing:Develop and maintain high-fidelity simulation software in C++ to support sensor fusion and mission system validation.Integrate third-party models and internal simulation components into a unified testing environment for Fusion applications.Analyze system and software requirements to ensure accurate representation of real-world behaviors in simulation environments.Troubleshoot software issues, identify defects, and support resolution through structured debugging and analysis techniques.Collaborate with cross-functional engineering teams including software, systems, and test engineers to ensure simulation accuracy and usability.Support Agile development processes and modern engineering workflows including Git-based version control and CI/CD pipelines.Ensure software quality through testing, validation, and continuous improvement of simulation fidelity and performance.Basic Qualifications:Bachelor's degree in Computer Science or Software EngineeringExperience coding in C++Experience analyzing requirementsExperience troubleshooting software & defect resolutionFamiliar with gitDesired Skills:Experience coding in C# or PythonExperience working in Agile teamsExperience with Linux operating systemsExperience with Jira and GitLabPay Information:Full-Time Salary Range: $98100.00 - $182100.00 At Lockheed Martin, we know mission success starts with taking care of our people.
