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.
As a Senior 5G Software Test Engineer focused on the Physical Layer, you will lead the verification, validation, and performance testing of 5G NR PHY software for 3GPP Release 15/16/17 and beyond-5G systems. Your primary focus will be ensuring correctness, performance, and robustness of real-time PHY implementations running on processor- and accelerator-based platforms.
You will work closely with PHY software developers, RF engineers, DSP teams, and hardware teams to validate PHY features, diagnose complex issues, and ensure high-quality, production-ready software. This position is based in the USA (Arlington, TX or Saratoga, CA). \n
\n This is a full time, exempt position, based out of our Saratoga office. The target base pay for this position is $150,000 - $200,000 annually. 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.
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. This means that there will be times when extra hours, including nights and weekends, may be needed to meet critical deadlines and mission goals. In return, we offer a dynamic work environment with opportunities for professional growth and development and the chance to make a meaningful impact in a high-growth industry.
