Job summary

Aalyria is hiring a Communication System Test Engineer to qualify coherent optical modem systems from component level to full system integration. You will own the test bench, select hardware, and perform root-cause analysis with Matlab or Python for data analysis.

You’ll design experiments, work with BERTs, AWGs, OSAs, and high-speed scopes, and collaborate across design, systems, and firmware teams to translate test results into product decisions. Eligibility for US export controls applies.

Qualifications

• Active security clearance or eligibility to obtain one.
• Bachelor’s or Master’s degree in Electrical Engineering, Optical Engineering, or a related field.

Responsibilities

• Assist in the selection and purchase of lab equipment and components to assemble test benches for qualifying optical communication systems.
• Set up and conduct lab experiments to evaluate coherent optical modems.
• Utilize lab instrumentation (BERTs, AWGs, oscilloscopes, OSAs, OPMs, VOAs, polarization controllers).
• Perform optical and electrical performance characterization of components and modules.
• Analyze results and support debug and optimization using Matlab or Python.
• Lead root-cause analysis and deep-dive debugging during testing.
• Prepare and present detailed test reports with findings and recommendations.

Job description

Role Overview:

The Aalyria Space team is building the infrastructure for the next generation of high-speed optical communications, and this critical role sits at the center of making it work in the real world. As a Communication System Test Engineer, you’ll be responsible for qualifying our coherent optical modem systems from component level through full system integration, owning the test bench from hardware selection all the way through root-cause analysis and final performance sign-off.

This isn’t a checkbox-testing role. You’ll design and execute the experiments that determine whether our free space optical communications products actually perform, setting up benches with BERTs, AWGs, high-speed oscilloscopes, OSAs, and coherent DSPs, writing the automation that makes testing repeatable and scalable, and digging into the data with Python or MATLAB when results don’t match the model. When something’s broken, you’ll be the one who figures out why.

You’ll work closely with design, systems, and firmware teams across the product lifecycle, not just catching issues, but shaping how performance is characterized, what specifications mean in practice, and how findings translate into product decisions. If you’re the kind of engineer who gets absorbed by a tricky optical link budget problem and won’t let go until you understand it, this role is built for you.

Key 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.

Required Qualifications:

• 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.

Preferred Qualifications:

• 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.

What We Offer:

• Innovative Environment: Work at a cutting-edge company shaping the future of aerospace communications.
• Impactful Work: Directly contribute to critical national security programs and initiatives.
• Growth Opportunities: Expand your career with opportunities for professional development and advancement.
• Inclusive Culture: Be part of a collaborative, supportive, and inclusive workplace where your contributions matter.
• Flexibility: Flexible working arrangements including hybrid remote/in‑office schedules.
• Compensation and Equity: Competitive salary, comprehensive benefits (401(k), dental, vision, health, life insurance), paid time off, and equity options.

ITAR/EAR Requirements:

This position involves access to export‑controlled information. To comply with U.S. government export regulations, applicants must meet one of the following criteria:

(A) Qualify as a U.S. person, which includes:

• U.S. citizen or national
• U.S. lawful permanent resident (green card holder)
• Refugee under 8 U.S.C. 1157
• Asylee under 8 U.S.C. 1158

(B) Be eligible to access export‑controlled information without requiring an export authorization.

(C) Be eligible and reasonably likely to obtain the necessary export authorization from the appropriate U.S. government agency.

The company reserves the right to decline pursuing an export licensing process for legitimate business‑related reasons.
