At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight!

Blue Origin is pioneering the future of space-based communications with Tera Wave, a revolutionary satellite communications network designed to deliver symmetrical data speeds of up to 6 Tbps anywhere on Earth. This multi-orbit constellation will consist of optically interconnected satellites in low Earth orbit (LEO) and medium Earth orbit (MEO), providing enterprise-grade connectivity for critical operations worldwide.

We are seeking a Principal Modem PHY IP Design Engineer to support the design and development of advanced modem physical layer (PHY) IP for the Terawave program. This role will contribute to the architecture, modeling, implementation, integration, and validation of modem PHY functions for next-generation high-performance wireless ASIC solutions.

The ideal candidate brings strong technical depth in digital communications and modem design, along with hands-on experience translating algorithms into implementation-ready hardware architectures. This engineer will work closely with systems, ASIC, RF, verification, FPGA, firmware, and validation teams to deliver robust and efficient PHY IP.Responsibilities
· Design and develop modem PHY IP for Terawave ASIC and prototyping platforms.
· Contribute to PHY algorithm development and hardware architecture for functions such as:o modulation and demodulationo timing and frequency synchronizationo channel estimation and trackingo equalizationo FEC integrationo MIMO / beamforming supporto 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/baseband architecture.
