Senior L1 PHY & Modem Engineer for High-Throughput Satellite

Blue Origin; Kraków; On-site; PLN 200,000 - 340,000; Full time

Job summary

Blue Origin LLC in Kraków, Poland, is seeking a senior L1PHY engineer to develop and optimize high‑throughput modem implementations for the TeraWave system. You will collaborate across DSP, ASIC, FPGA, firmware, BSP, and system engineering teams from pre‑silicon development through integration and validation.

The role emphasizes hands‑on work with C/C++ implementations, HW/SW partitioning, and performance tuning to meet strict throughput and latency targets in a space communications context.

Qualifications

• Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related technical discipline.
• 10+ years of experience in L1PHY software, modem implementation, DSP implementation, embedded communications software, or related areas.
• Strong understanding of OFDM-based communication systems and major transmit and receive PHY processing chains.
• Experience implementing or integrating L1PHY processing on CPUs, DSPs, SoCs, FPGAs, ASIC accelerators, or heterogeneous processing architectures.
• Strong understanding of HW/SW partitioning and hardware acceleration of computationally intensive modem functions.
• Experience with performance profiling and optimization, multicore processing, memory management, and efficient data movement.
• Experience working with interfaces between L1 software, embedded firmware, and custom hardware or hardware accelerators.
• Ability to work across modem, DSP, ASIC, FPGA, firmware, BSP, and system engineering teams.

Responsibilities

• Develop and optimize L1PHY and modem implementations for high-throughput satellite systems.
• Implement and integrate PHY processing functions including framing, FEC processing, rate matching, scrambling, modulation/demodulation.
• Develop and optimize C/C++ implementations of L1PHY and DSP processing functions for embedded and real-time modem systems.
• Define HW/SW partitioning across programmable processors, DSP engines, FPGA/ASIC hardware accelerators, and embedded software.
• Analyze and optimize modem processing across throughput, latency, computational complexity, memory bandwidth, data movement, and processor utilization.
• Optimize multicore processing, memory organization, buffering, concurrency, and hardware‑accelerator utilization for high‑throughput L1 processing.
• Work closely with modem algorithm engineers to translate communications and DSP algorithms into efficient production implementations.
• Work closely with ASIC, FPGA, firmware, BSP, and system engineering teams to define interfaces between L1 software and modem hardware accelerators.
• Support pre‑silicon verification, simulation, prototyping, system integration, and post‑silicon validation of L1PHY and modem implementations.
• Debug complex system‑level issues spanning L1 software, DSP processing, hardware accelerators, firmware, and ASIC interfaces.
• Evaluate modem architecture and implementation tradeoffs across performance, complexity, throughput, latency, memory, power, and hardware resources.
• Provide technical guidance and contribute to key L1PHY, HW/SW partitioning, and modem implementation architecture decisions.
