Job Title:         Layout Design Engineer (SerDes)

Location:        Cork , Ireland

Reports to:     Sr Principal Design Engineer

Job Overview:

The Layout Design Engineer will be responsible for transistor-level physical layout implementation of advanced analog and mixed-signal circuits for next-generation high-speed interface IP. This role sits within the SerDes Product Team based in Cork, Ireland, and works closely with cross-functional engineering partners to deliver high-quality, manufacturable designs.

Job  Responsibilities:

• Perform custom transistor-level layout for high-speed SerDes blocks, including PLLs, Clock and Data Recovery (CDR), TX/RX analog front-ends, equalisers (CTLE/DFE), bandgap and bias circuits, and high-speed clock distribution networks. 
• Partner closely with analog and mixed-signal circuit designers to understand performance requirements and optimise floorplanning, parasitic-sensitive routing, signal integrity, and matching. 
• Support physical design implementation activities such as floorplanning, device placement, routing, shielding and isolation, power planning, and EM/IR-aware layout practices. 
• Run and debug physical verification flows, including DRC, LVS, ERC, parasitic extraction, and post-layout verification support. 
• Apply advanced layout techniques such as common-centroid structures, interdigitation, symmetry constraints, guard rings, dummy fill, and matching-aware routing. 
• Optimise layouts for area, yield, performance, reliability, and manufacturability. 
• Collaborate with cross-functional teams including Analog Design, Digital Implementation, Packaging, Signal Integrity, and Physical Verification. 

Job Qualifications:

Essential (Must-have) 

• Degree in Electronic Engineering, Microelectronics, Computer Engineering, or a related discipline, or equivalent industry experience. 
• Hands-on experience with CMOS SERDES or high-speed I/O IC layout at the transistor level. 
• Practical knowledge of custom layout methodologies and parasitic-aware design techniques. 
• Ability to collaborate effectively with designers and project stakeholders across global teams. 
• Strong problem-solving skills, clear communication, and a collaborative working style. 

Desirable (Nice-to-have) 

• Experience with PHY GDS implementation, including PMA/PCS integration and clock/power distribution. 
• Familiarity with ASIC design flows, hierarchical physical design strategies, and deep sub-micron technology challenges. 
• Exposure to EM/IR, low-power design considerations, crosstalk analysis, physical verification, and DFM. 
• Experience contributing to tape-outs on advanced technology nodes (e.g. 16nm, 10nm, 7nm, 5nm, or 3nm). 
• Scripting or automation experience using Tcl, Perl, or Python. 
• Prior use of Cadence tools or collaboration with EDA R&D teams (e.g. Virtuoso, PVS).
