E-Space•Arlington, TX

12d•Onsite

About The Position

E-Space is seeking a Wireless Test and Automation Engineer to validate next-generation 5G communications systems that support its constellation and ground infrastructure. The role owns the test environment and strategy for 3GPP-based wireless features, with a focus on PHY and protocol stack verification. The engineer develops automated test suites, analyzes logs and packet captures, and collaborates with software, systems, and RF engineers to resolve issues and support reliable deployments across space and ground products. The position is based at the Arlington, Texas office. The engineer will configure and maintain laboratory and hardware-in-the-loop (HIL) wireless test automation environments; design and implement 5G NR test cases for 3GPP stack and PHY features; automate test execution, log collection, and results analysis; and run regression testing. The role includes detailed L1, L2, and L3 failure analysis, use of wireless measurement and channel-emulation equipment, defect tracking, test reporting, maintenance of test repositories, and improving test coverage and quality processes. Close collaboration across software, firmware, RF, systems, and product teams is expected, including incorporating testability into new features. This is a full-time, exempt position. Flexibility to occasionally work extended hours or weekends during critical periods is expected. E-Space cannot currently provide employment sponsorship for candidates who do not hold work authorization for the role’s location.

Requirements

Bachelor's or master's degree in electrical engineering, Communication Theory, Software Engineering/Development, or a related field.
At least 5 years of hands-on wireless test engineering experience, including at least 3 years specializing in 5G technology.
Documented experience testing 3GPP stack and PHY systems, with strong 5G NR experience.
Proficiency in Python scripting or an equivalent automation language.
Practical experience with wireless test and measurement tools such as Amarisoft, Viavi, Propsim, Spirent, Keysight, Rohde & Schwarz, or similar.
Experience with issue-tracking systems such as Jira and structured test processes.
Strong skills in analyzing logs and pcap captures, conducting structured failure analysis, and documenting findings clearly.
Excellent communication skills and ability to work in a fast-moving, cross-disciplinary environment.
Flexibility to occasionally work extended hours or weekends during critical periods.
Work authorization for the location of the role; E-Space is not currently able to provide employment sponsorship.

Nice To Haves

Experience testing satellite, non-terrestrial network (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 and release processes.
Experience in a startup or fast-paced R&D environment.
Direct experience in LEO satellite component development, design, and in-orbit activities.

Responsibilities

Set up and maintain scripting and automation environments for laboratory and HIL wireless test setups.
Derive, design, and implement 5G NR test cases for 3GPP stack and PHY-level features.
Develop Python or equivalent scripts to automate test execution, log collection, and result analysis.
Perform software regression testing to validate features, bug fixes, and releases.
Analyze L1, L2, and L3 logs to investigate failures, identify root causes, and recommend remediation.
Use wireless measurement and channel-emulation equipment to execute and debug test scenarios.
Track defects using an issue-tracking system and drive them through the full lifecycle with clear, reproducible descriptions.
Prepare concise test reports, maintain test repositories, and improve test coverage and quality processes.
Collaborate with software, firmware, RF, systems, and product teams to ensure new features are designed for testability.
