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 Communications Systems Automation engineer to build the automated test infrastructure validating our 5G Core stack. This role is software-first: you will design frameworks, build automations, and drive test coverage across a complex, multi-layer system. You will work closely with software, platform, and RF engineers to ensure every build is thoroughly validated before it reaches space. WHAT YOU WILL DO: * Design and implement a scalable test automation framework for 5G Core Network Functions across both virtualized and physical deployment targets. * Develop Python-based test scripts and harnesses covering functional, regression, integration, and performance scenarios. * Develop tooling for automated packet capture and protocol-level analysis to validate 5G stack behavior across interfaces. * Extend automation to cover physical hardware environments, including hardware-in-the-loop setups with embedded radio hardware. * Track, reproduce, and verify defects through their full lifecycle in Jira with clear, reproducible failure descriptions. * Collaborate with software, platform, and systems engineers to ensure testability is designed into new features from the outset. WHAT YOU WILL DO IN THIS ROLE: Bachelor’s or Master’s degree in Electrical/Computer Engineering, Computer Science, or a related field. 5+ years of software test automation experience in wireless communications, networking, or embedded systems. Strong Python programming skills. Strong Linux skills and Linux networking experience. Familiarity with CI/CD systems and integrating automated test suites into pipelines. Experience with virtualized infrastructure like VMWare or Proxmox. Strong defect tracking and reporting discipline using Jira or equivalent tools. BONUS POINTS FOR THE FOLLOWING: Experience with 5G core networks. Experience with physical RF equipment such as spectrum analyzers or channel emulators. Experience with non-terrestrial networks (NTN), satellite communications or other mission-critical wireless systems. Experience in a startup or fast-paced R&D environment. This is a full time, exempt position, based out of our Saratoga, CA or Arlington, TX office.    The total compensation packaged will be determined by various factors such as your relevant job-related knowledge, skills, and experience.    We are redefining how satellites are designed, manufactured and used—so we’re looking for candidates with passion, deep knowledge and direct experience on LEO satellite component development, design and in-orbit activities. If that’s your experience – then we’ll be immediately wow-ed.   E-Space is not currently able to provide employment sponsorship for candidates who do not hold work authorization for the location of this role.  The Company is not currently able to provide employment sponsorship for candidates who do not hold work authorization for the location of this role.
