About the Role
Radiant is seeking a Senior Electrical Engineer with a strong focus on digital signal processing (DSP) to lead the development of signal processing and data acquisition architectures for terrestrial reactor control systems, with a long-term path toward space reactor applications. You will serve as the technical authority for real-time signal processing, owning the design and deployment of DSP pipelinesâfrom requirements definition and algorithm development through implementation, validation, and deployment.
This role emphasizes end-to-end DSP development, including digital filtering, detection and estimation algorithms, and real-time processing on embedded processors and FPGA platforms. You will work closely with hardware teams to interface with mixed-signal systems (ADC/DACs, sensors), ensuring accurate sampling, low-noise signal conditioning, and robust performance in high-reliability environments critical to reactor control.
Responsibilities and Duties
Bachelorâs degree in Electrical Engineering, Computer Engineering, or a related field.
5+ years of experience in digital signal processing (DSP), including filtering, signal conditioning, estimation, and real-time signal analysis.
Strong proficiency in embedded C/C++ development and experience with real-time operating systems (RTOS).
Experience with analog and mixed-signal systems from a DSP perspective, including ADC/DAC interfacing, sampling theory, and quantization effects.
Hands-on experience with test planning, verification, and system debugging of DSP algorithms and embedded systems.
Ability to collaborate effectively across multidisciplinary engineering teams, including software, hardware, and system-level engineers.
