### 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
