Sr. Electrical Engineer - Radio Device RF Architecture Engineer

Motorola Solutions•Plantation, FL

2d•Onsite

About The Position

The Radio Device RF System Engineer will develop radio transceiver mixed-signal subsystems for high-reliability public safety communications equipment. The role uses commercial off-the-shelf ICs and RF components, as well as custom CMOS technologies and custom mixed-signal digital, RF, and analog circuits. The completed transceiver systems are intended for Motorola Solutions radio products. The position is 100% onsite, Monday through Friday, in Plantation, Florida. The engineer translates product-level radio requirements into microarchitectural specifications for mixed-signal circuits, including RF systems for PLLs, fractional multi-loop synthesizers, baseband and RF amplifiers and filters, AGC subsystems, and digital state machines for RF control. The role also develops behavioral system models, manages block-level specifications to meet overall system performance goals, assesses and integrates third-party IP and COTS ICs, and develops power-modeling and thermal-management strategies across operating modes and low-power states. The engineer collaborates with digital design, analog layout, firmware and software, verification, radio product, and test engineering teams through circuit and system specification, silicon tape-out, bring-up, and deployment into radio products. The team is part of Advanced Development Engineering, which designs and develops mission-critical communications equipment, RF modems, integrated circuits, and related circuit modules and subsystems.

Requirements

Bachelor's degree in Electrical Engineering.
10 or more years of radio transceiver design experience.
Proven digital radio transceiver development from concept to shipping product.
Background in RF and mixed-signal IC and RF PCB design.
Experience modeling, designing, and verifying analog/mixed-signal circuit blocks and feedback control systems such as PLL and AGC subsystems, using Cadence or equivalent CAD tools.
Knowledge of multi-loop feedback control systems and modeling.
Experience assessing third-party IP and COTS ICs for modem development.
Some experience with digital signal processing for modulation and demodulation in a faded radio channel environment.
Experience with Verilog-A, Verilog-AMS, System Verilog, or Universal Verification Methodology (UVM) for mixed-signal designs.
Familiarity with shell and scripting languages.
Excellent written and verbal communication skills and the ability to drive technical alignment across multidisciplinary global teams.

Responsibilities

Translate product-level radio requirements into microarchitectural specifications for mixed-signal circuits, with a focus on RF systems, PLLs, fractional multi-loop synthesizers, baseband and RF amplifiers and filters, AGC subsystems, and digital state machines for RF control.
Communicate and work with radio product development hardware and software architects to achieve product-level requirements.
Develop behavioral system models to determine and manage block-level specifications for radio modem lineups, with a focus on RF systems.
Arbitrate block-level specification adjustments throughout the design process to achieve overall system performance goals in finished silicon and radio products.
Collaborate with internal and external IP providers to integrate RF IP blocks into a SoC.
Develop power-modeling and thermal-management strategies across operating modes and low-power states for RF, digital, and analog mixed-signal systems.
Work with digital design, analog layout, firmware and software, verification, radio product, and test engineering teams from circuit and system specification through silicon tape-out, bring-up, and product deployment.
Assess third-party IP and commercial off-the-shelf ICs for modem development.
Design, model, and verify analog/mixed-signal circuit blocks and systems.
