Job description

We are building our freelancer bench for upcoming advanced full-custom analog layout projects. Location: Grenoble, France. Remote is possible with occasional on-site presence when needed.

• Silicon-ready mindset and clean verification closure
• Strong methodology for matching and parasitic awareness
• Ability to handle complex hierarchical TOP integration
• Clear communication and milestone-driven delivery

Technical Requirements

We are looking for strong hands-on expertise in the full-custom layout flow and physical sign-off.

• Physical verification: DRC, LVS
• Parasitic extraction (PEX), sign-off oriented
• Advanced CMOS nodes (typically below 28nm)
• Analog layout best practices: matching, symmetry, shielding, guard rings
• Awareness of variations, coupling effects, and IR-drop considerations
• Full-custom physical verification and closure methodology
• TOP-level integration and complex hierarchical interconnect management

Typical Deliverables

The scope depends on the project phase. Common deliverables include:

• Block layout execution
• Hierarchical assembly
• DRC closure support
• LVS closure support
• PEX extraction and review
• Coupling and noise mitigation
• Power routing and IR-drop awareness
• Final physical sign-off readiness

Nice to have

• Experience across multiple advanced nodes
• Mixed-signal blocks (ADC, PLL, LDO, sensor front-ends)
• Comfortable in reviews and cross-team coordination
