MATLAB Engineer — OFDM/OFDMA PHY Design & Simulation (Confidential Broadband Comms Project)

We're a stealth-mode team building a custom broadband wireless waveform and need an experienced MATLAB engineer to work on PHY-layer design, simulation, and link-level modeling for a proprietary OFDM/OFDMA system. Important context on the channel: This is not a 3GPP/cellular system. The channel is wideband, slow-fading, effectively AWGN-like — no multipath, no MIMO, no narrowband interference to model. If your background is mainly in cellular/Wi-Fi PHY design built around multipath and fading mitigation, that experience only partially transfers — we need someone comfortable reasoning about a cleaner, high-bandwidth link with a very different set of dominant impairments (think phase noise, frequency/timing offset, nonlinearities, and thermal-noise-limited performance rather than fading and interference). Scope: OFDM/OFDMA waveform design, parameterization (subcarrier spacing, CP length, pilot structure, etc.) Link-level simulation: BER/PER/throughput vs. SNR curves, synchronization algorithm design (timing/frequency offset estimation), channel estimation and equalization for the specific channel profile above Algorithm prototyping intended to hand off to a C++ implementation team (so clean, well-documented, translatable MATLAB — not just research-grade scripts) Possibly: modeling of specific RF front-end impairments [specify if relevant — phase noise, PA nonlinearity, ADC/DAC quantization, Doppler] Must have: Strong MATLAB (Communications Toolbox, Signal Processing Toolbox) Direct hands-on experience with OFDM or OFDMA PHY design — not just coursework/textbook familiarity. We want to see real link-level simulation work. Comfortable working from link-budget specs and translating algorithms into implementation-ready pseudocode/documentation Understanding of synchronization, channel estimation, and equalization fundamentals
