Principal Software Engineer

At Cadence, we hire and develop leaders and innovators who want to make an impact on the world of technology.

Cadence Design Systems is looking for a highly motivated Principal Software Engineer to join the Innovus R&D team.

Innovus is Cadence’s flagship digital implementation platform, enabling customers to design advanced semiconductor chips from RTL to GDSII.

In this role, you will play a key technical role in the development of advanced routing technologies for digital physical design,

with an emphasis on advanced bus routing and constrained routing , and routing quality of results.

You will drive the design and development of sophisticated routing algorithms, tackle complex physical-design challenges in advanced semiconductor designs,

and work closely with other R&D engineers to deliver scalable, robust, and high-quality solutions.

Key Responsibilities

• Architect, design, and implement algorithms for constrained routing and advanced bus routing
• Develop and optimize algorithms for advanced bus routing and constrained routing
• Drive routing solutions for complex pin-access, congestion, and multi-layer routing scenarios
• Improve quality of results, runtime, scalability, and robustness of routing technologies
• Provide technical leadership in analyzing and solving complex algorithmic, geometry, and routing problems
• Collaborate with R&D and cross-functional teams to define technical requirements, drive solutions, and deliver production-quality features
• Mentor junior engineers and contribute to the technical direction and long-term evolution of routing technologies

Minimum Qualifications

• MS or PhD in Computer Science, Electrical Engineering, Computer Engineering, or a related field
• Strong expertise in C/C++, algorithms, data structures, and object-oriented software development
• Experience developing complex, performance-critical software on Linux/UNIX platforms
• Strong algorithmic problem-solving, debugging, and software-design skills
• Ability to independently drive complex technical problems from problem definition through design, implementation, and validation
• Strong communication skills and ability to work effectively across engineering teams

Preferred Qualifications

• Experience in VLSI CAD, physical design, routing, computational geometry, graph algorithms, or optimization
• Knowledge of physical-design concepts such as routing layers, tracks, vias, blockages, pin access, congestion, and design rules
• Experience developing large-scale EDA or algorithm-intensive software systems
• Experience with routing algorithms, constrained optimization, geometry processing, or graph-based algorithms
• Familiarity with scripting languages such as Tcl, Python, or Perl
• Experience with commercial or academic place-and-route tools and physical-design flows

Experience providing technical leadership or mentoring engineers on complex software projects
