Jobs at Relative Dynamics Inc.

Develop and test GN&C flight software and automation for lunar spacecraft missions. Responsibilities include C/C++ development, real-time software, HWIL and SWIL integration, sensor and effector testing, 6-DOF simulations, navigation and flight-control analysis, and spacecraft performance evaluation. The role collaborates across software and hardware teams and requires on-site work in Houston or Glen Burnie.

Support selection, specification, integration, testing, qualification, and verification of spacecraft GN&C flight hardware for lunar missions. Responsibilities include developing requirements and interfaces, managing supplier and procurement activities, performing trade studies and risk assessments, supporting environmental and acceptance testing, troubleshooting integration anomalies, conducting HIL and system tests, and preparing technical documentation. The role also supports flight readiness, mission operations preparation, and post-test or post-flight analysis.

Develop and optimize Python software and relational database infrastructure supporting Landsat satellite data processing. Design database components, cloud-based workflows, and applications; improve performance and scalability; write tests; troubleshoot operational issues; and participate in planning, design, and code reviews. Collaborate with engineers, scientists, and mission stakeholders in a hybrid Sioux Falls role supporting USGS EROS Center initiatives.

Develop and test guidance, navigation, and control flight software for lunar satellite missions. Perform trajectory analysis, spacecraft dynamics and orbital mechanics analysis, 6-DOF simulations, sensor and effector integration, Kalman filtering, HWIL/SWIL testing, and real-time flight software development in C and C++. Collaborate with multidisciplinary teams to evaluate mission performance, support navigation hardware integration, and respond to customer and mission requirements.

Design and implement firmware and DSP algorithms for free-space optical communication terminals. Collaborate with optical, mechanical, and electrical teams, develop code and HDL for hardware, and contribute to product development across IRAD and SBIR projects.

Provide systems engineering support for satellite communications and ground station systems, including RF/antenna equipment maintenance, requirements development, interface definition, integration and test, configuration management, troubleshooting, and coordination with engineering and mission partners per established SEMP and standards.
