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 Qualifications:
- Active security clearance, or the eligibility to obtain one.
- M.S. or Ph.D. in Electrical Engineering, Computer Engineering, or related field.
- Strong foundation in:
- Digital signal processing
- Communication theory
- High-speed communication system design
- Hands-on experience with coherent DSP or high-speed SerDes/optical systems.
- Proficiency in MATLAB, Python, and/or C/C++ for modeling and algorithm development.
- Experience with:
- Adaptive equalization and synchronization algorithms
- FEC techniques (e.g., LDPC, Viterbi, soft decoding)
- System-level simulation and performance analysis
- Familiarity with ASIC/FPGA implementation flows and hardware constraints.
- Ability to translate theoretical algorithms into practical, power- and area-efficient implementations.
- Strong problem-solving skills and ability to work across multidisciplinary teams.
- Hands-on lab experience with high-speed communication systems.
- Experience with developing cycle accurate fixed point system models.
