Responsibilities

The principal engineer will lead algorithm design and delivery for routing features. Key responsibilities include:

  • Architect, design, and implement algorithms for constrained routing and advanced bus routing.
  • Develop and optimize routing algorithms for performance, scalability, and quality of results.
  • Address complex pin-access, congestion, multi-layer routing, and design-rule challenges.
  • Improve runtime, scalability, robustness, and routing quality of results.
  • Analyze and solve algorithmic, geometry, and routing problems impacting physical design.
  • Collaborate with R&D and cross-functional teams to define technical requirements and deliver production features.
  • Mentor junior engineers and guide the technical direction of routing technologies.

Requirements

Must-have technical skills and experience:

  • Proven expertise in C/C++, algorithms, data structures, and object-oriented design.
  • Experience developing complex, performance-critical software on Linux/UNIX platforms.
  • Strong algorithmic problem-solving, debugging, and software-design skills; ability to drive problems from definition through implementation and validation.
  • Strong communication skills and experience working effectively across engineering teams.
  • Ability to deliver scalable, robust, production-quality software.

Nice-to-have:

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

Education Requirements

MS or PhD in Computer Science, Electrical Engineering, Computer Engineering, or a related field. No alternative-equivalent degree language provided.
