Communications Systems Test Engineer

Aalyria • Livermore, CA

6h • Hybrid

About The Position

The Aalyria Space team is building the infrastructure for the next generation of high-speed optical communications. This critical role is responsible for qualifying coherent optical modem systems from the component level through full system integration, owning the test bench from hardware selection to root-cause analysis and final performance sign-off. The engineer will design and execute experiments to determine the performance of free space optical communications products, setting up benches with BERTs, AWGs, high-speed oscilloscopes, OSAs, and coherent DSPs. This includes writing automation for repeatable and scalable testing and performing data analysis with Python or MATLAB to debug issues. The role involves close collaboration with design, systems, and firmware teams across the product lifecycle, influencing how performance is characterized, what specifications mean in practice, and how findings translate into product decisions.

Requirements

• Active security clearance, or the eligibility to obtain one.
• Bachelor’s or Master’s degree in Electrical Engineering, Optical Engineering, or a related field.
• 2–5 years of hands-on lab experience working with high-speed communication systems.
• Solid understanding of Communication Theory and Digital Signal Processing.
• Proficiency with Matlab and/ or Python for data analysis and test automation.
• Experience using high-speed optical and electrical test equipment.
• Familiarity with coherent optical communication systems, including optical components such as tunable lasers, Mach-Zehnder (MZ) modulators, photodetectors, and EDFAs.
• Exposure to or experience with optical transceivers, coherent DSPs, and transponders.

Nice To Haves

• Familiarity with industry standards (e.g., OIF, ITU-T) and protocols relevant to high-speed optical transmission.
• Experience with automated test development and scripting for lab equipment.
• Working knowledge of LabVIEW or other test automation environments.
• Prior experience evaluating optical coherent modules or discrete transmitter/receiver components.

Responsibilities

• Assist in the selection and purchase of lab equipment and components to put together test benches needed for the robust qualification of our optical communication systems.
• Set up and conduct lab experiments to evaluate coherent optical modems.
• Utilize lab instrumentation such as Bit Error Rate Testers (BERTs), Arbitrary Waveform Generators (AWGs), high-speed Oscilloscopes, Optical Spectrum Analyzers (OSAs), Optical Power Meters (OPMs), Variable Optical Attenuators (VOAs), and Polarization Controllers.
• Execute optical and electrical performance characterization of discrete components and pluggable coherent modules.
• Analyze results and support debug and optimization of modem performance using Matlab, Python, or equivalent scripting tools.
• Lead root-cause analysis (RCA) and deep-dive debugging of performance issues found during system-level and component testing.
• Prepare and present detailed test reports, summarizing key findings, performance trends, and recommendations for cross-functional review.
• Develop and maintain automated test frameworks for repeatable and scalable evaluations.
• Collaborate closely with design, systems, and firmware teams to validate product functionality against specifications.
• Document test plans, results, and troubleshooting procedures clearly and efficiently.
