Senior Communications System Test engineer

What you will do:

System Integration & Testing

Define and execute comprehensive test plans to verify system-level communication performance across RF hardware, embedded software, and protocol layers.

Run both cabled and OTA test setups to validate link performance, signal integrity, timing accuracy, and system robustness under real-world and emulated conditions.

Perform detailed analysis of key performance indicators (e.g., EVM, throughput, link margin, error rates) and track against specifications.

Debug & Test Execution

Lead root-cause analysis of system issues observed during integration and testing.

Operate lab equipment (spectrum analyzers, signal generators, power meters, etc.) to troubleshoot RF and digital signal issues.

Collaborate with development teams to validate fixes and maintain test coverage as the system evolves.

Feedback Loop for Development

Provide structured feedback to hardware and software teams to guide improvements in design and implementation.

Participate in regular system integration reviews and serve as a key voice in product performance validation.

Manufacturing & RF Test Support

Contribute to test plan development and validation workflows used by RF and hardware manufacturing teams.

Support the transition of lab-based testing procedures to production environments.

Reporting & Documentation

Maintain test logs, issue trackers, and summary reports for engineering and leadership visibility.

Document reproducible test methodologies and contribute to internal verification standards.

What you bring to this role:

7+ years of experience in wireless communications system testing, preferably in RF and embedded environments.

Strong familiarity with digital communication concepts and RF performance metrics.

Experience with lab instrumentation and test environments (e.g., spectrum/VSA/VSG/VNA).

Ability to write test scripts or automate processes (Python, MATLAB, etc.) is a plus.

Understanding of 3GPP-based systems such as LTE or 5G is strongly preferred.

Comfortable working across teams and communicating technical findings clearly.

Ability to interpret test results in the context of overall system architecture and performance targets.

Bonus points for the following:

Bachelor’s or Master’s degree in Electrical Engineering, Telecommunications, or related field.

Experience with satellite communication systems or over-the-air RF testing.

Knowledge of test frameworks and signal generation tools for modem and protocol validation.

Familiarity with test plans for contract manufacturing environments.

Exposure to system-level verification in both lab and field conditions.
