Senior DSP Engineer, ALG, Amazon Leo Government

Amazon Leo is an initiative to launch a constellation of Low Earth Orbit satellites that will provide low‑latency, high‑speed broadband connectivity to unserved and underserved communities around the world. The mission of Amazon Leo Government (ALG) team is to leverage existing Kuiper technology and provide high speed, low latency, and secure satellite broadband services to the United States and our allied government customers.

• Interact directly with customers to understand technical requirements, and translate them into technically robust solutions backed by data and analysis.

• Develop and validate signal processing chains in MATLAB and Simulink, including fixed‑point modeling and bit‑true simulations.
• Implement and optimize FFT/iFFT architectures for OFDM waveforms, channelization, spectral analysis, and frequency‑domain beamforming.
• Collaborate with RF engineers, antenna engineers, and systems engineers to define interface requirements and performance budgets.
• Analyze system performance metrics (EVM, BER, SINR, beam patterns, sidelobe levels) and optimize DSP implementations.
• Develop calibration algorithms for phased array systems including amplitude/phase correction, mutual coupling compensation, and array manifold characterization.
• Model and simulate RF impairments (I/Q imbalance, phase noise, nonlinearity) and develop DSP‑based mitigation techniques.
• Perform trade studies on algorithm complexity, latency, throughput, and resource utilization.
• Deliver well‑written documentation, reports, and presentations for technical design reviews and as part of proposal efforts.
