Qualifications

• Entry-level engineers with curiosity and hands-on approach in test environments.
• Ability to translate requirements into clear test objectives and acceptance criteria.
• Exposure to RF, embedded systems, and mixed-signal test contexts is a plus.

Responsibilities

• Translate product, system, interface, and customer requirements into clear test objectives, methods, procedures, data needs, and acceptance criteria.
• Develop and maintain test plans, test cases, procedures, checklists, test configurations, data sheets, traceability records, and formal test reports.
• Configure and operate laboratory equipment, radios, network devices, embedded systems, channel emulators, RF components, computers, and automated test environments.
• Execute functional, performance, interoperability, regression, environmental-support, reliability, and acceptance testing under established procedures.
• Collect, organize, visualize, and analyze test data for metrics such as signal quality, frequency response, gain, noise, throughput, latency, packet loss, error rate, timing, thermal behavior, and system stability.
• Use oscilloscopes, spectrum analyzers, signal generators, network analyzers, power meters, logic analyzers, packet-capture tools, and comparable instruments as appropriate to the assignment.
• Create Python, MATLAB, Bash, or other scripts to automate equipment control, configuration checks, data collection, analysis, plotting, and report inputs.
• Document test anomalies, reproduce failures, isolate contributing conditions, support root-cause investigations, and verify corrective actions.
• Coordinate test readiness, equipment availability, calibration status, software and firmware baselines, test articles, interfaces, safety controls, and configuration records.
• Participate in laboratory and field testing, customer demonstrations, design reviews, test-readiness reviews, and technical-service deliverables.
