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
