Senior Software Engineer (Integrity 3D-IC Infra)

Job Title

Senior Software Engineer (Integrity 3D-IC Infra)

Role Summary

Develop digital central solutions and early-stage physical-design methodology for 3D-IC applications, focusing on pre-place-and-route (pre-PnR) flows rather than sign-off tools. Work closely with customers and foundry partners to translate design and advanced-node requirements into software solutions.

Collaborate with cross-functional teams to define architecture and deliver scalable software for large datasets and complex engineering workflows.

Experience Level

Senior. The posting does not state a specific years-of-experience requirement.

Responsibilities

Main responsibilities for the role include:

• Design and implement early-stage physical design flows (pre-PnR) for 3D-IC applications.
• Engage with customers and foundry partners to gather requirements and translate them into software designs.
• Contribute to architecture and high-level design decisions for large-scale data and software infrastructure.
• Develop, debug, and maintain code in large legacy codebases; ensure reliability and performance.
• Optimize software performance and capacity for desktop applications that handle large datasets.
• Collaborate across teams and communicate technical issues and trade-offs clearly.
• Independently learn new technologies, tools, and domain concepts as needed.

Requirements

Key technical skills and attributes. Must-have items are listed first; followed by nice-to-have items.

Must-have:

• Proficiency in Java (JDK 11–25) and strong object-oriented programming skills.
• Experience with Tcl scripting and Linux shell scripting.
• Solid knowledge of data structures, algorithms, and software engineering fundamentals.
• Ability to debug and maintain large legacy codebases and to reason about performance and capacity.
• Familiarity with UNIX/Linux environments; Windows knowledge is beneficial.
• Experience working with desktop applications that handle large-scale datasets.
• Good analytical, organizational and presentation skills; ability to work independently and communicate in English.

Nice-to-have:

• Experience with C++ (minor usage in this role).
• Experience with EDA/CAD tools and early-stage physical design flows (pre-place-and-route).
• Experience in software performance optimization, capacity planning, and usability design.
• Exposure to forward-deployed AI in engineering workflows.

Education Requirements

Preferred: Doctoral degree in Computer Science, Electrical Engineering, or a related field; alternatively a Master’s degree in Computer Science, Electrical Engineering, or a related field with 2+ years of relevant software development experience. (No other degree or certification requirements specified.)
