Job summary

Blue Origin in Seattle is seeking an experienced senior engineer to lead the design and optimization of PHY, modem, and DSP algorithms for the TeraWave system. You will model, simulate, and validate end-to-end performance.

Collaborate with ASIC, RF, firmware, and system teams, navigate pre-silicon to post-silicon validation, and contribute to architecture decisions that influence system-level behavior and reliability.

Qualifications

• Bachelor's degree in Electrical Engineering, Computer Engineering, or a related technical discipline.
• 10+ years of experience in communications systems, modem design, signal processing, or DSP algorithm development.
• Strong understanding of digital communications and signal processing fundamentals.
• Strong hands-on experience developing and simulating communications and DSP algorithms using MATLAB, Python, C/C++, or similar tools.
• Strong understanding of OFDM-based communication systems, including synchronization, channel estimation, equalization, modulation/demodulation, and frequency-domain signal processing.
• Experience developing and evaluating modem/PHY algorithms in end-to-end communication-system simulations.
• Understanding of practical RF and channel impairments and their impact on modem performance.
• Ability to work across modem, RF, ASIC, firmware, and system engineering teams.
• Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

Responsibilities

• Develop and optimize PHY, modem, and DSP algorithms for high-throughput satellite communication systems.
• Develop algorithms for synchronization, carrier and sampling frequency offset estimation and compensation, channel estimation, equalization, SNR estimation, modulation/demodulation, and other modem signal-processing functions.
• Develop MATLAB, C/C++, Python, or equivalent system-level models to evaluate modem algorithms and end-to-end communication-system performance.
• Model and analyze communication channels and impairments, including noise, fading, interference, frequency and phase errors, nonlinearities, and RF impairments.
• Evaluate modem architecture and algorithm tradeoffs across performance, complexity, throughput, latency, and implementation.
• Work closely with ASIC, RF, firmware, and system engineering teams to translate modem algorithms into the TeraWave implementation.
• Support pre-silicon verification, prototyping, system integration, and post-silicon validation of modem algorithms.
• Analyze end-to-end system performance and identify opportunities to improve modem and link performance.
• Provide technical guidance and contribute to key modem and communications-system architecture decisions.
