Staff Analog RF Design Engineer

Job Title: Staff Analog/RF Design Engineer (PLL Specialist)
Location: Dublin, Ireland
Position Type: Permanent
Start Date: ASAP

About the Role

We’re seeking a highly skilled Staff Analog/RF Design Engineer with deep expertise in PLL (Phase-Locked Loop) design to join a world-class IC development team working on cutting-edge UWB (Ultra-Wideband) 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 (Verilog-A/AMS) 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 (or equivalent).
• 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 (jitter, 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.

Nice to Have

• Experience in full-chip tapeouts and bringing RF ICs to production.
• Background in UWB, wireless transceivers, or other high-frequency RF domains.
• Familiarity with lab testing and debug tools (e.g. spectrum analyzers, VNAs, etc.).
