About the role
Communications DSP Engineer Communications DSP Engineer About Aalyria: Aalyria is a leading technology company that supplies laser communications technology and temporospatial software-defined networking platforms to the aerospace industry. With technology acquired from Google, Aalyria is at the forefront of innovation in satellite and airborne mesh networks, as well as cislunar and deep-space communications. We are revolutionizing the orchestration and management of planetary mesh networks using any radio or optical spectrum, any orbit, and any hardware across land, sea, air, and space. Role Overview: The Aalyria Space team is seeking a highly skilled DSP Engineer to develop next-generation modem technologies for free space optical communication systems. This role sits at the intersection of advanced digital signal processing, system architecture, and real-world hardware implementation. You will design and optimize DSP algorithms and architectures that enable robust, high-throughput links across challenging channels, helping push beyond current limits in coherent communications. You’ll collaborate closely with cross-functional teams spanning ASIC/FPGA design, RF/optical hardware, and system engineering to translate advanced algorithms into efficient, deployable modem solutions. This is a remote position that will include occasional travel to our Mountain View, CA location. Key
Responsibilities: Design, develop, and optimize coherent DSP algorithms for high-speed communication systems Architect end-to-end modem DSP chains including equalization, timing recovery, carrier recovery, and FEC integration. Perform system-level modeling, simulation, and performance analysis, including link budgets and channel impairments. Develop advanced algorithms such as: Adaptive equalization Timing and carrier synchronization loops Impairment mitigation Evaluate and model optical and electrical channels, including optical components, ADC/DAC, AFE, and mixed-signal impairments. Define DSP architecture specifications for ASIC/FPGA implementation, ensuring efficient mapping to hardware. Collaborate with hardware and firmware teams to integrate DSP algorithms into modem designs. Support lab bring-up, validation, and characterization of modem systems. Analyze relevant industry standards (e.g., OIF, Ethernet, optical transport) and incorporate them into designs. Required
