Senior To Staff C++ Engineer

Quilter is seeking Senior to Staff C++ Engineers to join our engineering teams developing the next generation of automated PCB design. You'll design high-performance C++ algorithms, data structures, and systems that tackle some of the hardest challenges in computational geometry, optimization, high-performance computing, and physics simulation. As a senior engineer, you'll shape the technical roadmap, mentor peers, and help build the foundation for superhuman PCB design.

You may contribute to one of several specialized teams:

  • Core Router Team: Build the algorithms and data structures that fundamentally define how circuit boards are routed, creating scalable, physics-aware routing engines.
  • Homotopy Team: Refine raw routing outputs into high-quality, manufacturable layouts using geometric transformations that enforce real-world PCB design rules.
  • Router Agent Team: Develop the infrastructure, parallelization, and APIs that power reinforcement learning agents and routing algorithms at massive compute scale.
  • Physics Team: Implement geometry checks and physics simulations—electromagnetic, thermal, and manufacturing—to validate routed boards for real-world performance.

What You'll Do

  • Architect and implement high-performance C++ libraries, algorithms, and systems for routing, optimization, and simulation.
  • Design scalable data structures and computational methods to handle complex PCB design challenges.
  • Strong collaboration skills and the ability to work with domain experts across different disciplines.
  • Provide mentorship, technical reviews, and guidance to elevate the team's engineering practices.

What We're Looking For

  • 3-10+ years of industry experience maintaining and extending large, high-performance C++ codebases in collaborative environments.
  • A strong academic background with deep expertise in one or more of the following areas: computational geometry, graph algorithms, optimization, high-performance computing (HPC), meshing, numerical methods, physics simulations, or related fields.
  • Proficiency in Python for prototyping and integration with ML systems.
  • Experience architecting and scaling large, collaborative C++ codebases.
  • Strong mathematical and algorithmic intuition, with ability to translate theory into production systems.
  • Leadership skills in mentoring, reviewing, and guiding engineering direction.
  • A passion for pushing the boundaries of what's possible in automated circuit design.

Nice To Have (General)

  • Advanced degree (M.Sc. or Ph.D.) in computer science, computational physics, robotics, or related fields.
  • Experience with reinforcement learning, CAD/EDA tools, or physics-based optimization.
  • Exposure to GPU programming (CUDA), parallel/distributed algorithms, or HPC frameworks.
  • Contributions to open-source geometry, simulation, or HPC projects.

Nice To Have (Per Team)

  • Core Router Team: Expertise in graph theory, computational geometry, operations research, optimization, numerical analysis, or simulation.
  • Homotopy Team: Background in geometric constraints, optimization methods, or mesh refinement.
  • Router Agent Team: Expertise with parallel programming, distributed systems, HPC frameworks, or API design.
  • Physics Team: Knowledge of simulations, physics engines, finite element methods (FEM), high-performance compute, or distributed compute.

Please note: We are an equal opportunity employer. At this time, we are focused on hiring primarily within the US, with occasional exception to accommodate exceptional talent.

What We Offer

  • Interesting and challenging work
  • Competitive salary and equity benefits
  • Health, dental, and vision insurance
  • Regular team events and offsites (~2x / year)
  • Unlimited paid time off
  • Paid parental leave
