System Performance Test Engineer (VoIP)

Requirements:

• Bachelors degree in Electrical Engineering, Computer Engineering, Computer Science, Telecommunications, or a related technical discipline, or equivalent relevant experience.
• Hands-on experience testing VoIP systems, including voice-channel performance testing beyond basic functional call testing.
• Experience evaluating voice-quality characteristics such as noise, crosstalk, frequency response, distortion, balance, gain, return loss, tone handling, and speech quality.
• Strong knowledge of VoIP and telecommunications fundamentals.
• Experience creating and carrying out formal test procedures and using equipment or software to capture and analyze voice-performance measurements.
• Strong troubleshooting and root-cause analysis skills, with the ability to document quantitative results and technical findings clearly.
• Experience with air traffic management, air traffic control voice communications, radio communications, FAA systems, or other mission- or safety-critical voice systems is preferred.
• Familiarity with SIP/RTP, Wireshark or other packet-analysis tools, Linux, network testing, Jira, requirements traceability, automated testing, or formal FAT/SAT environments is beneficial.

Responsibilities:

• Develop, execute, and document detailed performance test procedures for VoIP and voice communications systems.
• Test voice channels, interfaces, network components, and integrated communications equipment.
• Verify voice-channel performance requirements, including background and idle-channel noise, impulse noise, crosstalk, frequency response, intermodulation and harmonic distortion, longitudinal and hybrid balance, gain tracking, return loss, tone elimination, and speech quality.
• Configure test environments, instrumentation, endpoints, network connections, and system components for performance testing.
• Capture and analyze voice and network performance data, then compare measured results with requirements and acceptance criteria.
• Investigate performance anomalies and isolate issues across hardware, software, network, interface, and configuration layers.
• Record defects with test conditions, measurements, logs, and reproducible steps.
• Collaborate with systems, software, network, hardware, and test engineers to investigate and resolve performance issues.
• Conduct regression testing after software, hardware, network, or configuration changes.
• Support formal qualification testing, Factory Acceptance Testing, customer demonstrations, and system acceptance activities.
• Prepare test reports describing methods, measurements, results, failures, and conclusions.
