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).
