• Apply established testing principles, including test documentation, requirements traceability, test coverage, and verification methodologies.
• Perform functional, performance, security, integration, and system-level testing.
• Develop verification strategies and test specifications based on customer requirements, product requirements, hardware/software specifications, and operational use cases.
• Manage test environments for assigned programs, including test scripts, configurations, test equipment, and supporting infrastructure.
• Identify, analyze, and thoroughly document defects and unexpected system behavior, including clear steps for reproducing issues.
• Review and interpret system and software requirements from a testability and verification perspective.
• Maintain organized test records, results, and supporting documentation.
• Analyze historical test results to identify recurring issues, trends, and potential areas of improvement.
• Communicate technical issues, test results, risks, and project status to Test Management, Engineering teams, customers, and other stakeholders.
• Support informal testing, system verification, customer acceptance testing, and related Test & Integration activities.

• Hands-on experience testing Air Traffic Management systems, radio-control equipment, VoIP systems, advanced networking environments, or comparable mission-critical systems.
• Experience developing internal and customer-deliverable system-level test plans and procedures, preferably for mission-critical equipment within a production environment.
• Experience working with telecommunications systems and technologies, including VoIP, T1, ISDN, POTS, and TDM.
• Ability to develop clear, concise test plans and test procedures based on system requirements.
• Strong experience documenting, tracking, and communicating system defects and unexpected behavior.
• Excellent problem-solving, analytical, and technical troubleshooting skills.
• Minimum of 5 years of test-related professional experience, including hands-on hardware testing.
• Bachelor’s degree in Information Technology, Computer Science, Electrical Engineering, or a related technical discipline; equivalent relevant experience may be considered.

Preferred Technical Experience

• Experience working with digital and analog telecommunications, including VoIP and radio systems.
• Experience using industry-standard electronic and telecommunications test equipment, including:

o Oscilloscopes o Transmission Impairment Measurement Sets (TIMS) o Multimeters o Viavi T-BERD o Sage Multi-Channel Test Instruments

• Experience with commercial performance, simulation, and analysis testing tools such as VOTER, GL Communications TDM solutions, or comparable platforms.
• Familiarity with industry and government standards, including ED-137, MIL-STD-461G, FCC 47 Part B, FAA-G-2100H, FAA NextGen, and DO-278A.
• Experience with network and packet-analysis tools, particularly Wireshark.
• Familiarity with Linux operating systems and fundamental IP networking concepts.
• Experience with defect and requirements-management platforms such as JIRA and JAMA.
• Strong understanding of system testing methodologies, verification and validation, Agile/Scrum development processes, and project lifecycles.

Additional Skills

• Strong written and verbal communication skills.
• Excellent technical documentation capabilities.
• Strong analytical and troubleshooting skills.
• Ability to interpret complex system and software requirements.
• Ability to manage multiple tasks and projects concurrently.
• Ability to work effectively both independently and as part of a cross-functional engineering team.
• Comfortable communicating directly with customers, technical partners, engineering teams, and project stakeholders.
