Job description

Overview

Keysight is at the forefront of technology innovation, delivering breakthroughs and trusted insights in electronic design, simulation, prototyping, test, manufacturing, and optimization. Our ~15,000 employees create world-class solutions in communications, 5G, automotive, energy, quantum, aerospace, defense, and semiconductor markets for customers in over 100 countries. Learn more about what we do.

Our award-winning culture embraces a bold vision of where technology can take us and a passion for tackling challenging problems with industry-first solutions. We believe that when people feel a sense of belonging, they can be more creative, innovative, and thrive at all points in their careers.

About the Role

We are seeking an experienced Senior Software Engineer to help shape and advance the core architecture of a next-generation semiconductor design platform. In this role, you will play a key technical part in expanding data representations, system-level APIs, and high-performance execution engines optimized for complex 3D Heterogeneous Integration (3DHI) and programmatic workflows. You will partner with domain experts across physical layout, schematic verification, and simulation to enhance flexible, high-throughput systems that bridge high-level design intent with multi-physics verification engines. If you thrive on solving complex system modeling challenges, scaling software infrastructure, and guiding technical decision-making within a collaborative engineering environment, this position offers the opportunity to drive meaningful impact on our advanced EDA architecture.

Responsibilities

• Architectural Strategy & Technical Ownership: Drive key technical decisions, platform design, and long-term architectural evolution for core packaging engines, balancing system trade-offs across backend infrastructure and data representations.
• Programmatic & Interoperability Interfaces: Design and maintain scalable APIs, data-exchange layers, and execution pipelines that support code-first design flows, automated layout/schematic generation, and advanced multi-agent execution frameworks.
• Integration Frameworks: Help architect extensible, decoupled integration interfaces to enable smooth, low-latency interoperability with both internal solvers and third-party simulation tools (multiphysics, SI/PI, and DRC/LVS engines).
• Headless Infrastructure & Performance Optimization: Optimize high-throughput runtime engines for automated design-space exploration, batch execution, and deterministic performance in programmatic, headless operational environments.
• Design Rule & System Verification: Develop robust validation loops, constraint-checking mechanisms, and system-level observability to ensure programmatically generated designs consistently satisfy physical and manufacturability requirements.
• Cross-Functional Collaboration & Technical Mentorship: Partner closely with domain specialists, systems leads, and engineering teams to establish design standards, review complex codebases, and guide execution across the platform.

Qualifications

Required

• Bachelor’s, Master’s, or Ph.D. in Computer Science, Electrical Engineering, Computer Engineering or related technical field.
• 8+ years of software development experience, including 2+ years in software architecture
• Strong expertise in C++ and/or Rust.
• Demonstrated experience architecting complex data structures for large-scale engineering applications.
• Strong background in building low-latency, high-throughput backend services, or multi-threaded/concurrent data engines.
• Demonstrated ability to drive consensus on complex technical design trade-offs, author clear architecture specifications, and guide large feature initiatives across cross-functional engineering teams.
• Deep commitment to software quality, including automated test frameworks, deterministic build environments, CI/CD pipelines, and rigorous code-review practices.

Preferred Qualifications

• Strong proficiency in Python, with experience in C++/Rust integration
• Experience designing validation frameworks, rule-checking engines, and telemetry to track state changes and catch constraint violations early.
• Familiarity with programmatic interaction patterns or multi-agent execution frameworks designed to handle complex, iterative automation loops.
• Familiarity with electronic design and packaging abstractions, such as schematic connectivity, physical layout hierarchies, netlisting, or multi-die 2.5D/3D packaging concepts.

The level of role will be based on applicable experience, education and skills; Most offers will be between the minimum and the midpoint of the Salary Range listed below.
