Senior Staff SWE

### About Quilter At Quilter, we are helping electrical engineers save time and accomplish more by automating the tedious and time-consuming task of designing printed circuit boards (PCBs). Our small team is composed of experts in electrical engineering, electromagnetic simulation, ML/AI, and high-performance computing (HPC). We are inventing and leveraging novel techniques to solve the decades-old problem of automating circuit board design where today hundreds of billions of dollars are spent. We have raised $25 million in Series B funding from some of the very best and are charging full-speed toward our goal. No matter where we come from, we're united by a common vision for the future and a core set of values we think will get us there: 1. Focus on the mission 2. Build great things that help humans 3. Demonstrate grit 4. Never stop learning 5. Pursue excellence 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 (~4x / year) * Unlimited paid time off * Paid parental leave Want to learn more about Quilter, our vision, and our investors?
