Description
Thompson Software Solutions is seeking a Senior Software Engineer to support the development of embedded flight software and Guidance, Navigation, and Control (GNC) capabilities for an advanced missile platform. This role offers the opportunity to design and integrate mission-critical software operating in high-performance, real-time environments where precision, reliability, and deterministic execution are paramount.
As a Senior Software Engineer, you will develop embedded flight software, contribute to the architecture, design, implementation, integration, and verification of real-time systems supporting missile guidance, navigation, and control functions. You will work at the intersection of software, hardware, and control algorithms to ensure accurate sensor processing, state estimation, trajectory management, and actuator command execution under strict timing and performance constraints.
This position requires deep expertise in embedded and real-time software development, including low-level hardware interfaces, multi-threaded and deterministic system design, integration with GNC algorithms, and operation within safety- and mission-critical frameworks. Experience supporting hardware-in-the-loop (HIL) environments, simulation integration, system-level test, and flight qualification activities is highly valued.
You will collaborate closely with software engineers, GNC engineers, systems engineers, integration and test teams, and program leadership to mature capabilities from lab development through system qualification and flight test.
The successful candidate will join a high-performing software engineering team focused on delivering next-generation missile capabilities. This role requires strong systems thinking, exceptional analytical and troubleshooting skills, and the ability to lead in a fast-paced, high-consequence development environment where performance and reliability are mission critical.
Selected applicants will be subject to a government security investigation and must meet eligibility requirements for access to classified information. Continued eligibility for access to classified information is required throughout employment, as dictated by program needs.
