Department Overview

The communications systems team supports research, proof-of-concept test beds, and system engineering efforts focused on enhancing the capacity, interference resilience, and flexibility of future communications satellite and line-of-sight radio communications systems.

Current work includes the design and performance evaluation of advanced communications waveforms, flexible and adaptive wideband frequency plans, robust acquisition and tracking techniques, dynamic resource-allocation protocols, and advanced networking strategies.

Promising research results are verified through hardware and software proof-of-concept implementations that provide quantitative performance data and complexity insights.

System engineering activities apply new concepts and technologies to communications programs supporting mission-critical objectives.

Position Summary

The Integration & Test Engineer will work in a laboratory team environment to design, develop, and execute operational scripts and unit tests for wireless communications systems, including communications satellite payloads and associated ground terminals.

The individual will identify key requirements, create test plans, and apply strong programming and scripting skills to implement system- and unit-level tests.

This role is responsible for troubleshooting system issues by applying knowledge of system architecture, including software, firmware, and RF components, to identify root causes of system failures.

The engineer will also lead hands-on diagnosis of issues that arise during integration and testing and will work closely with software, firmware, and hardware teams to identify and resolve issues.

The individual should be able to travel to provide onsite support for fielded test equipment approximately 3–6 weeks per year, domestically.

The engineer will support technical staff in testing and maintaining test assets used in the development of satellite communications systems.

Required Skills

• Ability to apply programming skills to efficiently implement test procedures and troubleshoot system operation.
• Experience with system test planning and test execution.
• Strong background and hands-on experience with Python and Bash.
• Proficiency with the Linux operating system.
• Experience with test equipment automation.
• Strong oral and written communication skills.
• Willingness to work in a team environment and learn new skills.

Preferred Skills

• C/C++ programming experience.
• Recent experience debugging issues and resolving anomalies in a system test environment.
• Openness to using modern AI-assisted coding and testing tools to accelerate scripting and automation.
• Familiarity with data analysis and plotting.
• Embedded programming experience.
• Fluency with Wireshark and TCP/IP basics.
• Signal processing experience, including MATLAB, DSP, digital communications, and link budgets.
• Experience with FPGA boards, including VHDL exposure.
• DevOps experience, including CI/CD, Git, and automated build and test processes.
• Experience with communication theory and communication system design.
• Experience with end-to-end system integration, verification, and automated testing of RF communication links.
• Understanding of link budget analysis and overall system architecture for wireless or satellite communications.

Additional Information

This position is predominantly onsite; the individual should expect to be onsite 4–5 days per week. Some phases of the project lifecycle may require additional onsite presence.

Interim clearance or equivalent background screening may be sufficient to begin the role, if applicable.

Interview process typically includes an initial prescreen followed by a wider group interview.
