Principal Modem PHY IP Design Engineer - Terawave Verified today

About the Role

Blue Origin is developing TeraWave, a revolutionary satellite communications network with optically interconnected satellites in low Earth orbit (LEO) and medium Earth orbit (MEO), delivering symmetrical data speeds up to 6 Tbps anywhere on Earth. You will design and develop advanced modem physical layer (PHY) IP for next-generation high-performance wireless ASIC solutions.

Responsibilities

• Design and develop modem PHY IP for TeraWave ASIC and prototyping platforms.
• Contribute to PHY algorithm development and hardware architecture for modulation and demodulation, timing and frequency synchronization, channel estimation and tracking, equalization, FEC integration, MIMO and beamforming support, and impairment mitigation and calibration support.
• Translate system and link requirements into implementation-ready PHY block specifications.
• Develop floating-point, fixed-point, and bit-accurate models for modem PHY functions.
• Perform performance analysis and trade studies across throughput, latency, area, and power.
• Work with architecture and RTL teams to partition algorithms into efficient hardware implementations.
• Support interface definition and subsystem integration for PHY IP within the broader modem and baseband architecture.
• Collaborate with verification teams to define test strategies, reference models, and coverage plans.
• Analyze simulation, emulation, FPGA, lab, and silicon data to debug design issues and improve PHY performance.
• Support bring-up and validation of modem PHY features in FPGA prototypes and silicon.
• Document design assumptions, architecture decisions, performance results, and implementation details.
• Work effectively with internal teams and external design partners to drive execution.

Minimum Qualifications

• Bachelor's degree in Electrical Engineering, Computer Engineering, Applied Mathematics, Physics, or related technical field.
• 10+ years of experience in wireless communications, modem PHY design, DSP, or ASIC/FPGA-based baseband development.
• Strong background in digital communications theory and modem implementation.
• Experience in several of the following areas: OFDM and/or single-carrier systems, synchronization algorithms, channel estimation and equalization, adaptive modulation and coding, FEC such as LDPC, Polar, Turbo, or BCH, fixed-point analysis and quantization, MIMO or beamforming techniques.
• Proficiency with MATLAB, Python, C/C++, or similar tools for modeling and simulation.
• Experience translating algorithms into hardware-oriented architectures for ASIC or FPGA implementation.
• Strong analytical, debugging, and problem-solving skills.
• Ability to work across cross-functional teams in a fast-paced development environment.

Preferred Qualifications

• Master's or PhD in Electrical Engineering, Signal Processing, Communications, or related field.
• Experience with modem PHY design for mmWave, sub-THz, Terahertz, satellite or space communications, 5G/6G systems, or high-throughput wireless backhaul or mesh systems.
• Familiarity with RTL design and verification flows.
• Experience with FPGA prototyping, lab characterization, and silicon bring-up.
• Knowledge of RF and mixed-signal impairments such as phase noise, carrier offset, nonlinearities, and calibration effects.
• Experience working with external IP vendors or design service partners.
• Ability to work effectively in an ambiguous, fast-moving development environment.
