Job Title: Signal and Power Integrity Lead Application Engineer

Location: Vélizy, Sophia or Grenoble, France

Reports to: Sr Principal Application Engineer

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

Cadence is committed to equal employment opportunity and employment equity throughout all levels of the organization. We strive to attract a qualified and diverse candidate pool and encourage diversity and inclusion in the workplace. 

Travel: Regular local travel within France to visit customers on-site (~20–30% of working time).
