RF Data Link Engineer II

What You Will Do Perform and/or evaluate concept and performance trade studies, link budget analyses and demonstrate developed capabilities for data link communication applications. Perform hardware and software communication architecture trade studies. Develop, prototype, and test data link models and communication signal processing algorithms in high‑fidelity simulations and support hardware implementation. Test, verify, and validate communication and signal processing algorithm requirements and performance in laboratory or field test environments. Provide engineering support through participation in project design reviews, peer reviews, briefings to internal leadership, and external customers for all phases of development tasks. Design communications systems, develop data link hardware, and create algorithms for digital signal processing. Qualifications Minimum of 2 years of relevant experience. Minimum 2 years of programming and/or simulation experience in MATLAB, SIMULINK, C/C++, or equivalent language. At least two of the following: communication theory, digital signal processing, probability theory, stochastic signal processing, RF and electromagnetic theory. Master’s degree in electrical or computer engineering with a focus in digital communications, communications systems design, data link hardware development, waveform algorithm development, or digital signal processing is preferred. Experience with system engineering of RF subsystems, waveform simulations (PSK, FSK, OFDM, QAM), and familiarity with common RF impairments (phase noise, multipath, Doppler). Knowledge of link budget and propagation modeling, RF transceiver and front‑end design tradeoffs, antenna design parameters, fixed‑point algorithm simulations for VHDL verification, wireless fading model simulation. Understanding of Layer2 and above network layers. Strong technical and interpersonal skills, ability to support enterprise initiatives, prepare documentation with minimal oversight, and design for manufacturability, producibility, and cost constraints. Strong problem‑solving skills with the ability to identify alternate solutions to overcome difficult technical challenges.
