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 deliveryassociated 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 Wireless Communication Systems Engineer, you will be responsible for modeling, simulating, and designing the physical layer modem for a LEO satellite constellation communication network. This role is critical for ensuring reliable and efficient data transmission in advanced satellite communication systems. In this role, you will leverage your expertise in system analysis, modem design, including time/frequency unite, FEC design, modulator, and demodulator in an advanced wireless communication system.

This position will report to the Sr. Director of Product and System Integration, Silicon and you will work closely with systems, software, hardware, and test teams that are responsible for delivering the communications payload. This position is based in our Arlington, TX office.

What you will do:

Modeling and Simulation
Develop and implement detailed mathematical models of physical layer communication systems for LEO satellite networks
Use simulation tools to evaluate and optimize the performance of communication systems under various conditions and scenarios
Analyze the impact of various physical layer impairments on system performance and suggest mitigation techniques
Design and Development
Design the architecture and algorithms for physical layer modems, including modulation, coding, synchronization, and channel estimation
Develop prototypes and conduct lab tests to validate the performance of the designed modem
Work closely with hardware and software teams to ensure seamless integration of the physical layer modem with other system components
Performance Analysis
Perform detailed performance analysis of the designed communication system, including link budget analysis, throughput, latency, and error rates
Identify and resolve performance bottlenecks and ensure the modem meets the required specifications and standards
Documentation and Reporting
Document all design and development processes, simulation results, and performance evaluations
Prepare technical reports and presentations for internal and external stakeholders
Stay updated with the latest advancements in satellite communication technologies and incorporate relevant innovations into the design process
Collaboration and Support
Collaborate with cross-functional teams, including system architects, hardware engineers, and software developers
Provide technical support and expertise during system integration and field trials
Participate in design reviews, code reviews, and provide constructive feedback

What you bring to this role:

10 years of experience
Strong background in communication theory, digital signal processing, and wireless communication systems
Proficiency in modeling and simulation tools such as MATLAB, Simulink, or equivalent
Experience in designing and developing physical layer modems
Familiarity with satellite communication systems, particularly LEO networks
Excellent problem-solving skills and the ability to work independently as well as in a team environment
Strong analytical and communication skills. Team player.

Bonus points for the following:

Strong knowledge of 3GPP standards, preferably 5GNR
Knowledge of modern coding techniques and standards such as LDPC, Turbo Codes, or Polar Codes
Experience with hardware implementation and testing of communication systems
Familiarity with software-defined radio (SDR) platforms and tools
Strong programming skills in languages such as C/C++, Python, or VHDL/Verilog
Master’s or Ph.D. degree in Electrical Engineering, Telecommunications, or a related field

This is a full time, exempt position, based out of our Arlington office. The total compensation packaged will be determined by various factors such as your relevant job-related knowledge, skills, and experience.
