This position offers a hybrid work option, with the ability to work remotely up to four days per week and at least one day in-office in Santa Maria, CA.
Responsibilities:
Apply sound software engineering practices throughout the system life cycle to support physics-based simulations, visualization tools, and launch support systems.
Develop and maintain a high-fidelity trajectory simulation for satellite launch vehicles written in Fortran, C++, and JavaScript.
Support ongoing efforts to expand and modernize the C++ codebase, implementing high-performance architectures and software design patterns that optimize simulation speed and maintainability.
Design, implement, and support pre- and post-processing tools in MATLAB, C++, JavaScript, Perl, and Python to assist with trajectory builds, analysis, and validation.
Apply a test-focused development approach, including unit testing with Google Test (GTest) and automated regression testing through GitLab CI/CD pipelines.
Collaborate with IV&V analysts and mission support engineers to investigate and resolve simulation discrepancies.
Interface with customers, suppliers, and technical teams to ensure software tools meet operational needs.

Proficiency in one or more of the following languages: Fortran, C++, MATLAB, Perl, Python, JavaScript.
Experience using Git or similar version control systems.
Experience writing software design or technical documentation.
Desired:
Experience developing, troubleshooting, or analyzing flight vehicle or trajectory simulations.
Strong math and physics foundation (e.g., dynamics, optimization, probability).
Experience with GitLab CI/CD pipelines, automated documentation tools (Doxygen), and Agile collaboration platforms (Jira, Confluence).
Experience with unit testing frameworks such as Google Test (GTest) and test-driven development practices.
Experience integrating and using external C++ libraries such as Eigen, Boost, nlohmann/json, or Redis clients for high-performance computing and data handling.
