Wireless Test and Automation Engineer - 5G PHY & Stack

About the role

Ready to make connectivity from space universally accessible, secure and actionable? Then you’ve come to the right place!

E-Space is bridging Earth and space to enable hyper-scaled deployments of Internet of Things (IoT) solutions and services. We are building a highly-advanced low Earth orbit (LEO) space system that will fundamentally change the design, economics, manufacturing and service delivery associated with traditional satellite and terrestrial IoT systems.

We’re intentional, we’re unapologetically curious and we’re 100% committed to innovate space-based communications and deliver actionable intelligence that will expand global economies, protect space and our planet and enhance our overall quality of life.

We are looking for a Wireless Test and Automation Engineer to help us validate next generation 5G communications systems that will power our constellation and ground infrastructure.

In this role, you will own the test environment and test strategy for 3GPP-based wireless features, with a strong focus on PHY and protocol stack verification. You will develop automated test suites, analyze logs and pcap traces, and work closely with software, systems, and RF engineers to drive issues to closure and ensure high-reliability deployments for our space and ground products.

This position is based in our Arlington, TX office.

What you'll be doing: · Set up and maintain the scripting and automation environment around wireless test setups (lab and HIL).

· Derive, design, and implement 5G NR test cases for 3GPP Stack and PHY-level features.

· Develop Python (and/or equivalent) scripts to automate test execution, log collection, and result analysis.

· Perform software regression testing to validate new features, bug fixes, and releases.

· Analyze L1, L2, and L3 logs to perform detailed failure analysis, identify root causes, and provide clear remediation recommendations.

· Use wireless measurement and channel emulation equipment (e.g., 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.

What you will bring to this role: · Bachelor's or master's degree in electrical engineering, Communication Theory, Software Engineering/Development, or related field.

· 5+ years of hands-on wireless test engineering experience, including 3+ years specializing in 5G technology

· Documented experience testing 3GPP Stack and PHY systems, with strong 5G NR.
