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.

What you will do:

• Understand system requirements and architecture in depth.
• Define, develop, and execute advanced test methodologies for validating end-to-end system level functionality and performance (lab & field) across the mobile protocol stack (PHY, MAC/RLC/PDCP, RRC, NAS, Data, TCP-IP/UDP).
• Execute manual and automated testing of wireless systems, including functional and performance testing.
• Ensure timely execution, test accuracy and repeatability.
• Document test results, test coverage and other KPIs and communicate to all stakeholders regularly.
• Deep-dive into test results and root-cause issues and communicate with the appropriate teams.
• Responsibilities will also include defining Key performance Indicators and conducting modem performance evaluation.
• Design lab setups for various types of tests, including conducted clean channel and fading channel test and field tests.
• Build racks and other test-rigs as necessary for executing the test plan.
• Automate the test execution including control and configuration of test equipment.
• Collaborate with multi-disciplinary teams – hardware, software, mechanical, systems, etc. – in different time-zones to ensure that system requirements will be met during operation.

What you bring to this role:

• Master’s degree in electrical engineering, wireless Communication Engineering, Telecommunications, or a related field.
• 7+ years of hands-on experience in testing cellular and other communication systems in the industry with a successful product launch history.
• Strong background in communication theory, digital signal processing, and wireless communication systems, especially in the context of satellite systems.
• Solid understanding of 3GPP specifications (LTE & NR Air Interface, PHY, MAC, RLC, RRC, PDCP and NAS layer) for 5GNR and 4G.
• Knowledge of RF transceiver measurement techniques such as noise figure, gain/power, ACLR, Linearity, phase noise, etc.
• Excellent problem-solving with a from-first-principles approach.
• Proficiency in using test equipment (e.g., power supplies, oscilloscope, spectrum analyzer, signal generator, power meters, vector network analyzer).
• Exposure to modeling and simulation tools such as MATLAB, Simulink, or equivalent.
• Proficiency in test automation using Python or similar programming language.
• Experience using JIRA and other CRM tools.
• Flexible, responsive, and collaborative with an ability to work at a fast-paced startup environment.
• Strong analytical and communication skills. Team player.

Bonus points for the following:

• Experience in NTN, Redcap or NB-IOT.
• Some satellite, aerospace, or related industry experience.
• Strong theoretical background in communication theory.
• Expertise in digital communication theory, including coding and modulation, information theory, and detection and estimation.
