Senior Wireless Communications Systems Engineer

Senior Wireless Communications Systems Engineer Join E-Space as a Senior Wireless Communications Systems Engineer. E-Space is bridging Earth and space to enable hyper‑scaled IoT deployments via a low Earth orbit satellite constellation. Responsibilities Model and simulate physical layer communication systems for LEO satellite networks. Develop and implement mathematical models of modulation, coding, synchronization, and channel estimation. Use simulation tools (MATLAB, Simulink, etc.) to evaluate and optimize system performance under various conditions. Analyze physical layer impairments, suggest mitigation techniques, and perform link budget, throughput, latency, and error rate analysis. Design architecture and algorithms for physical layer modems, develop prototypes, and conduct lab tests to validate performance. Collaborate with hardware, software, and systems teams to integrate the modem into the payload and support system integration and field trials. Document design processes, simulation results, performance evaluations, and prepare technical reports and presentations. Participate in design reviews, code reviews, and provide constructive feedback. Qualifications 10+ years of experience in communication theory, DSP, and wireless communications. Strong background in modeling and simulation tools such as MATLAB or Simulink. Experience designing and developing physical layer modems for satellite or LEO networks. Proficiency with FEC design, modulation and demodulation, synchronization, and channel estimation. Excellent problem‑solving skills and ability to work independently and in a team. Strong analytical and communication skills. Experience with C/C++, Python, or VHDL/Verilog is preferred. Master’s or Ph.D. in Electrical Engineering, Telecommunications, or related field is a plus. Bonus Skills Knowledge of 3GPP standards, preferably 5GNR. Experience with modern coding techniques 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 C/C++, Python, or VHDL/Verilog. Benefits Competitive salary and total compensation package. Opportunities for professional growth and development. Health and wellness care options. Paid holidays and paid time off. Financial solutions and optional legal services (US only). Location Arlington, TX.
