Signal and Power Integrity Lead Application Engineer

Job Responsibilities: 

• Perform Signal Integrity (SI) and Power Integrity (PI) analysis in both time and frequency domains to support customer design validation and sign-off 

• Apply SI/PI methodologies including IBIS, TDR, impedance control, transmission line theory, and Power Distribution Network (PDN) characterisation across IC package and PCB designs 

• Conduct IR drop and AC-level PDN optimisation to meet target impedance and power ripple requirements on customer use cases 

• Design and configure system-level, time-domain test benches incorporating IBIS-AMI models and interconnect structures for high-speed protocol sign-off (LPDDR5, UCIe, CEI-OIF, and others) 

• Collaborate with customers to analyse IC packages and PCBs using the latest interconnect technologies, including DDR5/LPDDR5 and PCIe 5 

• Drive technical campaigns and software evaluations with customers, delivering clear and compelling technical presentations to varied audiences 

• Train and onboard new customers on Sigrity SI/PI analysis workflows and Clarity 3D full-wave electromagnetic (EM) extraction 

• Partner with internal sales, product engineering, and R&D teams to develop and deliver tailored, customer-focused technical solutions 

• Build trusted relationships with customers across France, spending time on-site to understand and address their specific design challenges 

• Contribute to the global Application Engineering community by sharing technical insights and best practices with international colleagues 

Job Qualifications: 

• Master’s degree in Electrical Engineering, Electronics Engineering, or equivalent professional experience 

• 3–6 years of experience in Signal Integrity, Power Integrity, or a closely related electromagnetic design role 

• Solid background in EDA tools with applied knowledge of IC package and PCB design methodologies 

• Proficiency in SI/PI simulation workflows, including PDN analysis, high-speed protocol characterisation, and 2.5D/3D EM model extraction 

• Fluency in French and English (both written and spoken) - direct customer engagement in French is essential, with internal collaboration conducted in English 

• Valid work and residence permit in France 

Additional Skills/Preferences: 

• Hands-on experience with Cadence Sigrity tools and/or the Clarity 3D electromagnetic solver 

• Familiarity with thermal analysis methodologies alongside SI/PI workflows 

• Experience presenting technical content to both technical and non-technical audiences in a customer-facing or pre-sales environment 

• Exposure to emerging high-speed interconnect standards such as UCIe or CEI-OIF
