Descrição

• Own complete RF subsystems on client programs from the antenna port through the front-end, frequency conversion, and data converters into DSP and/or FPGA fabric • Define RF architectures and frequency plans, including IF and LO selection, Nyquist zone and sampling plans, clocking, filtering, and lineup specifications • Design transmit chains from baseband through up-conversion, including drivers, filters, power amplifiers up to 10 W, ALC, detector-based output-level control, and output protection • Design receive chains, including digitally intensive sampling architectures, LNA lineups, down-conversion, variable gain and AGC, interferer rejection, and input protection • Model and budget system performance, including noise figure, sensitivity, dynamic range, linearity, EVM, phase noise, and jitter • Specify and select RF/microwave filters and components, including custom parts developed with third-party vendors • Configure digital signal paths using RFSoC hard IP, DUC/DDC, decimation/interpolation filters, sample-rate conversion, and FIR synthesis • Drive RF and microwave PCB layout with layout and signal integrity teams • Build manufacturability features such as factory calibration hooks, digital correction filters, and ATE register access • Verify and characterize performance in the lab using spectrum and signal analyzers, VNAs, vector and analog signal generators, and power meters • Develop technical estimates and risk mitigation strategies • Work closely with clients to produce well-documented, maintainable designs that withstand review • Collaborate across FPGA/DSP, hardware, embedded software, verification, SI/PI, PCB layout, and mechanical/thermal design teams • Support client engagements through at least 20% domestic and international travel

🎯 Requisitos

• Bachelor's degree in Electrical Engineering, Computer Engineering, or equivalent • Master's in RF/microwave engineering or communications is an asset • 8+ years designing RF and wireless hardware • Familiarity with FDD and TDD techniques • Experience interacting with FPGA, DSP, PCB Layout, and Signal Integrity designers • Experience with PLL topology and loop filter design, VCO/DRO and LO multiplier specification, TCXO and VCXO selection, and phase noise and jitter specification and measurement • Fluency with RF and microwave filters and components, including printed, SAW/BAW/FBAR, ceramic resonator, discrete L/C, waveguide, cavity, circulators, isolators, couplers, dividers, and hybrids • Experience specifying custom parts with vendors • Antenna selection, interface specification, and vendor management experience • Expert-level use of RF modeling and simulation tools such as Keysight ADS, SystemVue, MATLAB/Simulink, or Cadence AWR equivalents • Hands-on capability with microwave test equipment • Experience with RF schematic capture, PCB layout collaboration, RF/microwave component selection, and debugging HW/RF/FPGA integration from schematics and datasheets • Knowledge of communication and wireless standards • Excellent communication skills and fluency in English • Ability to present technical findings and trade-offs concisely to internal teams and clients • Strong technical judgment with emphasis on quality and rigor • Willingness to learn new technologies • Readiness for occasional travel, typically within North America • Phased array and beamforming design is nice to have • DPD, CFR, and envelope tracking experience is nice to have • Link budget analysis is nice to have • Regulatory certification experience with FCC, ISED, or ETSI is nice to have • Direct-RF sampling architectures on AMD Zynq RFSoC or Versal devices is nice to have

🏖️ Benefícios

• Medical, dental, and vision plans • Matching 401(k) contributions • Annual profit-sharing bonus • Other supplementary benefits • Fully remote work arrangement • Opportunity to work on diverse, high-complexity electronic systems and emerging technologies • Collaboration with cross-functional teams and clients • Accommodations available upon request during the recruitment process
