Principal Digital Signal Processing Engineer, RF Payloads

YOUR MISSION

True Anomaly is seeking a Principal Digital Signal Processing Engineer to lead the architecture, development, implementation, and integration of advanced DSP capabilities for space-based RF payloads. 

In this role, you will develop real-time processing systems for high-rate complex I/Q data collected from RF sensors, phased arrays, SIGINT payloads, radar systems, and software-defined radios. You will own DSP efforts across the full development lifecycle—from algorithm development and modeling through implementation on embedded processors, FPGAs, GPUs, and other flight computing platforms. 

The ideal candidate is a technical leader who can take algorithms from initial analysis through real-time implementation, hardware-in-the-loop testing, payload integration, and delivery. You will work closely with RF, antenna, FPGA, software, hardware, systems, and payload engineers to define architectures that meet demanding requirements for bandwidth, latency, memory, power, and computational resources. 

Experience in one or more of the following areas is highly desirable: phased-array signal processing, digital beamforming, SIGINT, electronic warfare, radar, RF sensing, software-defined radio, communications, or geolocation. 

RESPONSIBILITIES

• Define DSP architectures and technical roadmaps for RF payloads, including requirements, interfaces, implementation approaches, and verification strategies. 
• Develop and implement real-time DSP algorithms for high-rate complex I/Q data. 
• Design processing chains that include digital downconversion, channelization, polyphase filter banks, decimation, resampling, filtering, and spectral analysis. 
• Develop algorithms for signal detection, characterization, classification, modulation recognition, and signal parameter estimation. 
• Develop and evaluate algorithms for phased-array processing, digital beamforming, adaptive beamforming, direction finding, angle-of-arrival estimation, and adaptive nulling. 
• Support SIGINT, electronic warfare, RF sensing, and signal exploitation architectures. 
• Support radar signal processing, including pulse compression, range-Doppler processing, detection, tracking, and waveform analysis, as applicable. 
• Develop algorithms for frequency, phase, and timing synchronization, calibration, interference mitigation, and low-SNR signal processing. 
• Analyze real-world recorded and streaming I/Q data to evaluate system performance and troubleshoot signal-processing issues. 
• Develop high-fidelity simulations and test environments using MATLAB, Python, C++, or similar tools. 
• Translate floating-point algorithms into efficient fixed-point, embedded software, FPGA, GPU, DSP, or other hardware implementations. 
• Perform fixed-point, bit-true, quantization, bit-growth, overflow, dynamic range, and numerical accuracy analysis. 
• Optimize processing systems for throughput, latency, memory bandwidth, power, clock rate, and available computational resources. 
• Work with FPGA and software engineers to define hardware/software interfaces, data formats, timing requirements, memory architectures, and processing pipelines. 
• Develop production-quality software and firmware, including automated testing, code reviews, version control, and configuration management. 
• Develop and execute algorithm verification and validation plans using simulated, laboratory, field-collected, and hardware-in-the-loop data. 
• Support RF payload bring-up, hardware integration, system testing, environmental testing, and on-orbit commissioning. 
• Lead root-cause analysis and corrective action for DSP, payload, and system-level performance issues. 
• Define and manage requirements, interfaces, technical documentation, design reviews, and verification closure. 
• Serve as the technical authority for payload signal processing in architecture reviews, design reviews, customer engagements, and program milestones.&nb
