Senior/Staff Software Engineer (C++)

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: Focus on the mission Build great things that help humans Demonstrate grit Never stop learning 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 rout
