Job description

Wireless Test Engineer – Arlington, TX

E‑Space is building a low‑Earth‑orbit space system to revolutionize IoT. We seek a Wireless Test Engineer to validate next‑generation 4G/5G communications that power our constellation and ground infrastructure. This position is based in our Arlington, TX office.

Responsibilities

• Set up and maintain scripting and automation environment for wireless test setups (lab and HIL).
• Derive, design, and implement test cases for 3GPP Stack and PHY‑level features (LTE and preferably 5G NR).
• Develop Python (or equivalent) scripts to automate test execution, log collection, and result analysis; contribute light C code where needed.
• Perform software regression testing to validate new features, bug fixes, and releases.
• Analyze test logs and pcap files to perform detailed failure analysis, identify root causes, and provide clear remediation recommendations.
• Use wireless measurement and channel emulation equipment (Amarisoft, Viavi, Propsim, Spirent, Keysight, Rohde & Schwarz) to execute and debug test scenarios.
• Track defects and issues using an issue‑tracking system such as Jira, driving them through the full lifecycle with clear, reproducible descriptions.
• Prepare and deliver concise test reports, maintain test repositories, and contribute to continuous improvement of test coverage and quality processes.
• Collaborate closely with cross‑functional teams (SW, FW, RF, systems, product) to ensure testability is designed into new features from the outset.

Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, Communication Theory, Software Engineering/Development, or a related field.
• 5+ years of hands‑on test engineering experience in wireless technology.
• Documented experience testing 3GPP Stack and PHY systems, with strong expertise in LTE and preferably 5G NR.
• Proficiency in Python scripting (or equivalent automation language), with familiarity in C.
• Practical experience using wireless test and measurement tools such as Amarisoft, Viavi, Propsim, Spirent, Keysight, Rohde & Schwarz, or similar.
• Experience with issue‑tracking systems (e.g., Jira) and structured test processes.
• Strong skills in analyzing logs and pcap captures, performing structured failure analysis, and clearly documenting findings.
• Excellent communication skills and the ability to work in a fast‑moving, cross‑disciplinary environment.
• Experience testing satellite, non‑terrestrial networks (NTN), or other mission‑critical wireless systems.
• Background in test architecture for HIL systems or large‑scale automated regression frameworks.
• Familiarity with CI/CD pipelines and integrating automated tests into build/release processes.
• Experience in a startup or fast‑paced R&D environment.
