## Job description

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’re looking for a Test Automation Engineer to help develop and maintain a reliable, scalable validation infrastructure for 5G Core and device-side network functions spanning both virtualized labs and physical hardware environments. This role will work closely with senior engineers to implement and enhance automation solutions and Test for next-generation wireless systems.

What you will do:

- Develop and maintain a scalable test automation framework across virtualized and physical deployments of 5G Core and device network functions.
- Write Python automation scripts and test harnesses for functional, regression, integration, and performance testing.
- Develop tools to automate packet capture and protocol-level analysis, verifying correct 5G stack behavior across interfaces.
- Support hardware-in-the-loop testing involving embedded radio hardware and lab equipment.
- Analyze automation failures, debug issues, and help distinguish product defects from infrastructure or automation framework issues.
- Develop and maintain automation code using Git-based development workflows.
- Own defect lifecycle management in Jira: reproduce issues, document them clearly, and track them through resolution.
- Collaborate closely with software, platform, systems, and test engineers to improve automation coverage and test efficiency.

What you bring to this role:

- Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related discipline.
- 2–5 years of experience developing test automation for wireless, networking, embedded, or distributed systems.
- Strong Python programming skills.
- Good working knowledge of Linux, including shell scripting, networking, and system debugging.
- Experience with Git and collaborative software development workflows.
- Experience building and maintaining automated test suites.
- Familiarity with CI/CD pipelines.
- Experience working with virtualized environments such as VMware, Proxmox, or similar.
- Strong problem-solving skills and a disciplined approach to debugging and defect tracking.

Nice to have:

- Experience with 5G Core or radio access network technologies.
- Familiarity with RF test equipment such as spectrum analyzers, signal generators, or channel emulators.
- Experience with Wireshark, tcpdump, or similar network analysis tools.
- Exposure to Non-Terrestrial Networks (NTN), satellite communication

Additional Requirements This is a fast-paced, high-impact environment - flexibility to occasionally work extended hours or weekends during critical periods is expected.

Why E-Space is right for you:

As a member of our team, you will play a crucial role in driving our success.  Our team members have a strong sense of dedication and responsibility; this includes a strong commitment to our mission to create an entirely new suite of global capabilities to improve lives, business efficiencies and build a smarter planet.

## About E-Space

## Company Overview
- **One-liner**: E-Space is building the world's most sustainable low Earth orbit (LEO) satellite network designed to connect billions of devices and deliver secure, real-time data and AI-driven insights anywhere on Earth.
- **Entity Type**: Private (Seed stage; $50M total funding)
- **Headquarters**: Arlington, Texas, United States
- **Founded**: 2021
- **Founders**: Greg Wyler (previously founded O3b Networks and OneWeb)

## Core Business
- **Primary industry**: Telecommunications / Space technology (LEO satellite communications)
- **Target customers**: B2B, B2G — governments, defense agencies, critical infrastructure operators, logistics & asset tracking firms, digital agriculture, and enterprise IoT customers
- **Mission**: "Make data universally available, secure and actionable anywhere on the planet."

## Products & Services
- **E-Space LEO Platform**: A low Earth orbit satellite constellation (planned 100,000+ satellites) that securely connects billions of small, easy-to-install devices anywhere on Earth. Data can be routed to data centers or processed with edge AI (AIoT) for real-time insights and automation.
- **Constellations-as-a-Service**: Enables governments and enterprises to operate, control, and monitor their own satellite systems, allowing every nation to become "spacefaring."
- **Defense & Security Solutions**: A resilient satellite system designed for defense applications, leveraging space as "the ultimate high ground."
- **Critical Infrastructure & ESG Monitoring**: Rapid-deploy connectivity for monitoring critical infrastructure and Earth's sensitive resources, positioning E-Space as an "ESG partner to the planet."

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total Funding — USD $50M (Seed round, February 2022, led by Prime Movers Lab; additional venture round in November 2024). Annual Revenue — EUR 3.4M (estimated).
- **Notable Investors/Partners**: Prime Movers Lab (lead seed investor)
- **Growth Signals**:
  - Completed Beta-1 and Beta-2 satellite launches (execution beyond theory)
  - Acquired CommAgility (December 2022) for USD $14.5M, bringing wireless/5G expertise in-house
