Sr EDA Engineer

Position Title:

Senior EDA Engineer Cadence Virtuoso, SKILL/CDF, Tool Integration

Role Overview:

We are seeking a highly skilled EDA Engineer with solid experience in Cadence Virtuoso

environments and a deep understanding of OpenAccess databases, SKILL scripting,

foundry PDK/CDK integration, and schematic/layout tool automation. This role will

collaborate closely with AI/EDA development teams to build seamless design flows and

robust automation for our AI-powered analog design platform.

Key Responsibilities:

• Develop, maintain, and optimize analog/mixed-signal IC design flows in

Cadence Virtuoso and related EDA tools.

• Create, modify, and optimize SKILL scripts for automation of layout, schematic,

verification, and design environment tasks.

• Manage Component Description Format (CDF) parameters and configurations

for foundry PDK and CDK components/libraries.

• Work extensively with the OpenAccess (OA) database API (using C++, Python,

Tcl) to read, write, and manipulate design data including schematic, layout,

connectivity, and library information.

• Develop automation tools and workflows leveraging OpenAccess to integrate

schematic and layout views, support PDK/CDK validation, and assist design

data migration or QA.

• Integrate and validate foundry PDK/CDK devices, parameterized cells (pCells),

symbols, DRC/LVS decks, and simulation models with EDA tools.

• Troubleshoot issues related to PDK integration, OA database consistency,

schematic-layout synchronization, and environment setups.

• Document technical processes, create reusable automation scripts, and

contribute to team best practices.

• Collaborate with AI and software teams to integrate EDA tools into AI

co-pilot platform and support continuous improvement of design automation.

Required Skills & Experience:

• 310 years hands-on experience working with Cadence Virtuoso analog/mixed-

signal design flows.

• Strong proficiency in SKILL scripting for automation within Cadence schematic

and layout environments.

• Proven experience managing and customizing CDF files for parametric device

libraries in Cadence.

• Hands-on experience with OpenAccess (OA) database API: Familiarity with OA

schema, ability to program in C++, Python, or Tcl to develop tools/scripts that

access and modify OA layout and schematic data.

• Deep understanding of foundry PDK/CDK structures, including parameterized

cells, symbols, device models, layout generators, and associated design-rule

decks.

• Experience automating schematic and library processes using scripting

languages (SKILL, Tcl, Python).

• Solid knowledge of schematic editors/viewers and maintaining schematic-

layout synchronization (LVS/Schematic Driven Layout).

• Strong UNIX/Linux command-line skills and scripting abilities.
• Experience with version control systems/tools used in EDA environments (Git,

SOS, or equivalent).

• Excellent communication skills and ability to operate effectively in a startup

team environment.

Preferred Qualifications:

• Previous work experience at Cadence or semiconductor companies specializing

in Virtuoso toolchains.

• Experience with Spectre, ADE simulation, and analog verification flows.
• Understanding of semiconductor process technology and device physics

applicable to analog/mixed-signal design.

• Familiarity with AI/ML integration in design tools is a plus.
• Notice Period:
• Immediate or upto 30 days
