Design jobs in France

We are looking for a Principal System Design Architect to take technical ownership of a major digital subsystem within a sophisticated SoC.

This role is for asenior digital designerwho leads architecture and RTL implementation, makes independent design decisions, and sets the technical bar for correctness, scalability, and robustness.

You willlead a defined technical area, influence design direction beyond your immediate team, and deliver solutions that materially impact product quality and programme success.

• Be responsible for themicro-architecture and RTL designof a sophisticated digital subsystem or IP.
• Translate system requirements intoclean, scalable RTL architectures.
• Leadmulti-clock domaindesign:
• CDC architecture and partitioning
• Clock gating and clock-enable strategy
• Robust reset synchronisation
• Leadmulti-power domaindigital design
• Power-state aware RTL
• Isolation, retention, and reset interactions
• Power sequencing considerations
• DriveSoC-level integration readiness, including:
• Interface definition and ownership
• Clock, reset, and power integration
• Performance and latency trade-offs
• Make and defendindependent design trade-offs
• Producehigh-quality design documentation
• Lead and influencedesign reviews, challenging weak designs and raising overall design quality.
• Mentor engineers onsophisticated digital design techniques.
• Collaborate with verification, physical design, and validation teams to ensure design intent is correctly realised

Digital design & RTL

• Expert-levelSystemVerilog / Verilogfor synthesizable RTL.
• Confirmed experience designinglarge, sophisticated RTL blocksthat are:
• Readable and maintainable
• Parameterised and reusable
• Scalable across projects
• Strong command of:
• FSMs and control logic
• Pipelines and latency management
• Arbitration and flow control
• Error handling and recovery

• Deep experience withmulti-clock domain systems:
• CDC mechanisms (async FIFO, handshakes, synchronisers)
• Clock domain partitioning
• Robust reset architecture design:
• Global vs local reset strategy
• Safe bring-up and recovery

• Experience designingmulti-power domaindigital logic.
• Strong understanding of how power intent affects RTL structure and behaviour.
• UPF awareness (authoring not required).

• Good understanding of SoC fundamentals:
• Interconnects (AMBA)
• Addressing and memory-mapped control
• Performance bottlenecks and contention
• Ability to reason beyond local RTL into system-level impact.

• Experience leading design reviews and technical direction.
• Recognised as atechnical authorityin digital design.
• Comfortable owning decisions that affect a significant part of the product.

• Strong design-for-verification
• Clean interfaces
• Observability and debuggability
• Targeted assertions where appropriate
• Ability to review verification results and debug issues.
• Verification ownership is not the focus of this role.

• Daily use of RTL simulators (Cadence / Synopsys / Siemens).
• Experience with lint, CDC, and basic static analysis tools.
• Comfortable in large Unix-based design environments.
• Scripting (Python / Tcl / Bash) to support design productivity.

• ASIC / SoC digital design experience.
• Confirmed ownership of at least onemajor design block end-to-end.
• Degree in Electrical Engineering, Computer Engineering, or equivalent experience.

• Experience with memory controllers, high-speed IO, fabrics, or sophisticated control subsystems.
• Prior exposure to timing closure considerations.
• Familiarity with formal techniques (nice to have, not required).

You’ll work ongroundbreaking SoCs, with the autonomy to shape design direction, influence architecture decisions, and see your designs impact products used across the industry.
