Job Title:
Senior Analog RF Design Engineer (PLL Specialist)
Location: Dublin, Ireland
Position Type: Permanent
About The Role:
We are seeking a highly skilled Senior Analog RF Design Engineer with deep expertise in PLL design to join our IC development team working on cutting-edge UWB products.
This is a senior individual contributor role with significant influence over architecture and implementation, supporting products used in mobile, automotive, IoT, industrial, and consumer applications.
You will take ownership of PLL design at both the system and circuit level, developing solutions that operate up to 20GHz and meet stringent performance, power, and area requirements.
Key Responsibilities:
* Lead the design, modeling, and verification of high-performance PLLs, including fractional-N/integer-N architectures, VCOs, loop filters, and dividers.
* Collaborate closely with system architects to define PLL performance targets and integration strategies.
* Work with layout engineers to ensure robust, low-noise physical implementation.
* Produce high-quality behavioral models for system integration and top-level verification.
* Contribute to the design of supporting analog RF blocks, e.g. LNA, PA, bandgap, ADC/DAC, mixers, etc.
* Participate in chip bring-up, lab validation, and debug alongside test and characterization teams.
* Provide technical mentorship to junior engineers and support knowledge sharing across the design group.
Qualifications & Skills:
* MSc or PhD in Electrical Electronic Engineering.
* 10+ years experience in analog RF IC design, with a focus on PLL development.
* Proven ability to design PLLs from concept to silicon, including deep understanding of system-level trade-offs jitters, phase noise, lock time, etc.
* Expert in Cadence Virtuoso, Spectre, and behavioral modeling in Verilog-A/AMS.
* Experience working in advanced CMOS nodes 40nm and below.
* Solid grasp of RF systems and analog mixed-signal design practices, including DFT and design reviews.
* Strong communication and documentation skills.
