We build and connect technologies to help protect people, property and places. Our solutions foster the collaboration that’s critical for safer communities, safer schools, safer hospitals, safer businesses, and ultimately, safer nations. Connect with a career that matters, and help us build a safer future.

The Radio Device System Engineer will work with commercial off-the-shelf ICs as well as custom CMOS technologies to develop RF transceiver systems to be utilized in hi-reliability public safety communications equipment. This position will be one of a team of advanced technologists that will conceive, design and implement radio systems with off-the-shelf semiconductor devices as well as custom mixed signal digital, RF and analog circuits and subsystems using robust design methodologies for deployment in two way radio equipment. The completed RF transceiver systems are intended for use in Motorola Solutions radio products.  

The following are activities related to this job and require prior experience: 

• System Architecture & Definition: Translate product-level radio requirements into comprehensive architectural specifications for mixed-signal SoCs including antenna tuners, PLLs, fractional multi-loop synthesizers, ADCs and DACs, baseband and RF amplifiers/filters, AGC sub systems,  digital state machines, embedded microprocessors, memories,  memory interfaces. Must be able to communicate and work with radio product development hardware and software architects to achieve product level requirements.
• System Level Modeling: Develop behavioral system models to accurately determine and manage block level specs for a radio modem lineup including hardware, firmware and software components. Arbitrate block level spec adjustments throughout the design process to accomplish the overall system performance goals on finished silicon and complete radio product implementation.
• IP Evaluation & Integration`: Collaborate with internal and external IP providers to integrate high-speed analog peripherals, data converters (ADC/DAC).
• Power & Performance Optimization: Develop power-modeling and thermal management strategies across multiple operating modes and low-power states 
• Cross-Functional Collaboration: Work closely with digital design, analog layout, firmware/software, verification, and test engineering teams from specification to silicon tape-out, bring-up and ultimately deployment into radio products. Work with external contractor SMEs to define and implement specialized subsystems in our custom IC designs.
• Documentation: Work with team members to document transceiver and sub-systems requirements, theory of operation, step-by-step functional operation instructions, troubleshooting, engineering & manufacturing test procedures and related procedures.

• Solid experience in analog/mixed-signal circuit block and feedback control system modeling like PLL and AGC subsystems, design and verification using Cadence or equivalent CAD tools. 
• Knowledge of multi-loop feedback control systems and modeling such systems.
• Experience in assessing 3rd party IP and COTS ICs for modem development.
• Experience with embedded processors. 
• Experience with digital signal processing as applied to modulation and demodulation of signals in a faded radio channel environment.
• Experience implementing high-speed interfaces (hyperRAM MIPI, LPDDR, Ethernet) within a radio modem and mitigating interaction with RF signal processing.
• Knowledge of SoC power management architectures, clocking schemes, and voltage domains.
• Experience with Verilog-A/Verilog-AMS/System Verilog/Universal Verification Methodology (UVM) for digital and analog/mixed signal (AMS) designs. Familiar with shell and scripting languages 
• Experience as a technical team leader and providing direction to other technical staff in the development of radio transceivers.
• Excellent written and verbal communication skills; proven ability to drive technical alignment across multidisciplinary global teams.\Proven radio transceiver development from concept to shipping product.
• Background in RF & mixed-signal IC and RF PCB desig
• Proven radio transceiver development from concept to shipping product.
• Background in RF & mixed-signal IC and RF PCB design.
