Senior Electrical Engineer, Radio Device RF Architecture Engineer

Job Title

Senior Electrical Engineer, Radio Device RF Architecture Engineer

Role Summary

Member of the Advanced Development Engineering team in Plantation, FL responsible for designing radio transceiver mixed-signal subsystems for mission-critical public safety communications. Work focuses on RF modems, mixed-signal ICs, RF components and PCB subsystems used in Motorola radio products.

This is a full-time, on-site role (Monday–Friday) involving system architecture, modeling, IP integration, silicon bring-up and cross-functional collaboration with firmware, digital, analog layout, verification and test teams.

Experience Level

Senior - requires extensive experience; basic posting indicates 10+ years of radio transceiver design experience.

Responsibilities

Primary technical and delivery responsibilities include:

• Translate product-level radio requirements into mixed-signal RF microarchitectures (PLLs, synthesizers, baseband and RF amplifiers/filters, AGC, RF control state machines).
• Develop behavioral system models to derive and manage block-level specifications for radio modems and RF subsystems.
• Evaluate, select and integrate internal and external RF IP and COTS ICs into SoC and PCB solutions.
• Perform power modeling and thermal management strategy development across operating modes and low-power states.
• Design, model and verify analog/mixed-signal circuit blocks and feedback control subsystems (e.g., PLL, AGC).
• Collaborate closely with digital design, firmware, layout, verification, product and test teams through tape-out, bring-up and product deployment.
• Assess third-party IP and COTS components for modem and transceiver development.
• Document designs, communicate technical trade-offs, and drive alignment across multidisciplinary global teams.
• Occasional travel under 10% for collaboration or integration activities.

Requirements

Must-have technical skills and experience:

• Proven track record of digital radio transceiver and radio modem subsystem development from concept to shipped product.
• Strong background in RF and mixed-signal IC design as well as RF PCB design.
• Solid experience in analog/mixed-signal block and feedback-control system modeling (PLLs, AGC) and verification using Cadence or equivalent tools.
• Experience evaluating and integrating 3rd-party IP and COTS ICs for modem development.
• Familiarity with mixed-signal verification and languages: Verilog-A, Verilog-AMS, SystemVerilog, and UVM; comfortable with shell/scripting tools.
• Applied knowledge of digital signal processing for modulation/demodulation in fading radio channels.
• Excellent written and verbal communication skills with demonstrated ability to drive technical alignment across global cross-functional teams.

Nice-to-have:

• Experience with custom CMOS mixed-signal design and SoC RF IP integration.
• Experience with fractional multi-loop synthesizers, advanced power/thermal optimization, and system-level power modeling.

Education Requirements

Bachelor's Degree in Electrical Engineering required.
