About the role
Xona Space Systems is seeking a Communications / DSP Engineer to own end-to-end signal-chain system engineering for GEO backhaul and inter-satellite cross-links, lead vendor integration, and drive FPGA-ready solutions in a high-performance PNT satellite infrastructure environment.
Responsibilities
- Algorithm & Hardware Evolution: Develop acquisition, tracking, data decoding, and measurement algorithms; collaborate across the team to drive the architectural transition from mathematical models to fixed-point, optimized FPGA designs and verifications.
- High-Fidelity Simulation: Build Python/C++ simulations and analyze performance under low-SNR, high dynamics, interference, and multipath.
- Integrated Architecture: Define HW/SW partitioning and system interfaces; optimize for FPGA resource utilization and timing constraints while ensuring requirements traceability.
- Measurement Product Definition: Specify measurement products (code phase, carrier, Doppler, C/N₀, PRs, DRs) and validate with Navigation team.
- Vendor & Lifecycle Management: Lead vendor SOWs, acceptance tests, integration, and compliance reviews. Document system architecture, simulations, trade studies, and verification results.
Qualifications
- MS or PhD in EE, CE, or related field; 7+ years’ experience in digital communications, DSP, or satellite systems.
- Strong mastery of synchronization, ranging, and spread-spectrum algorithm design.
- Hands-on experience with FPGA-based signal processing and bit-true/fixed-point modeling.
- Proficiency in Python, C/C++ for system modeling.
- Prior experience in vendor technical leadership and cross-functional system integration.
