Job Overview:
This is a high-impact, customer-facing role within Cadence’s Application Engineering organisation, where you will serve as a technical expert in Signal Integrity (SI) and Power Integrity (PI) — working directly with some of the world’s most innovative technology companies.
You will guide customers through complex SI/PI design challenges on IC packages and PCBs, leveraging Cadence’s industry-leading Sigrity and Clarity 3D toolsets across next-generation interconnect technologies including DDR5, LPDDR5, and PCIe 5.
Based at one of our three French offices - Vélizy, Sophia, or Grenoble - you will join a collaborative international team spanning the US, Europe, and Asia-Pacific, with outstanding opportunities to deepen your technical expertise and make a tangible impact on customer success.
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
