You will work closely with circuit designers, layout engineers, and EDA vendors to ensure efficient and robust design environments. 

Key Responsibilities: 

• Develop and maintain analog/mixed-signal design flows using industry-standard EDA tools (Cadence Virtuoso, Spectre, etc.). 

• Automate design tasks using scripting languages (e.g., Python, SKILL, Tcl, Perl). 

• Support schematic, layout, simulation, and verification environments. 

• Collaborate with design teams to understand requirements and improve design productivity. 

• Integrate and validate PDKs (Process Design Kits) and technology files. 

• Provide documentation, training, and support for CAD tools and flows. 

• Interface with EDA vendors to evaluate and deploy new tools and features. 

• Monitor and resolve CAD tool issues, ensuring high availability and performance. 

Required Qualifications: 

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or related field. 

• 3+ years of experience in analog/mixed-signal CAD or EDA tool development. 

• Strong knowledge of analog/mixed-signal IC design methodologies. 

• Proficiency in scripting languages such as SKILL, Python, Tcl, or Perl. 

• Experience with Cadence Virtuoso, Spectre, and AMS simulation environments. 

• Familiarity with PDK integration and technology file management. 

• Excellent problem-solving, communication, and teamwork skills. 

Preferred Qualifications: 

• Experience with digital-on-top (DoT) or mixed-signal verification flows. 

• Knowledge of version control systems (e.g., Git, Perforce). 

• Familiarity with Unix/Linux environments and shell scripting. 

• Exposure to advanced process nodes (e.g., 7nm, 5nm). 

We know that creativity and innovation happen more often when teams include diverse ideas, backgrounds, and experiences, and we actively encourage everyone with relevant experience to apply, including people of color, LGBTQ+ and non-binary people, veterans, parents, and individuals with disabilities.
