Senior/Staff Software Engineer (C++)

Job Overview

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).

Job Description

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.

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.

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.

Key Responsibilities

• 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.
• 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.
• Leadership skills in mentoring, reviewing, and guiding engineering direction.

Required Skills and Qualifications

• Strong collaboration skills and the ability to work with domain experts across different disciplines.
• What We’re Looking For 3-10+ years of industry experience maintaining and extending large, high-performance C++ codebases in collaborative environments.
• Experience architecting and scaling large, collaborative C++ codebases.
• Leadership skills in mentoring, reviewing, and guiding engineering direction.
• Experience with reinforcement learning, CAD/EDA tools, or physics-based optimization.
• Physics Team: Knowledge of simulations, physics engines, finite element methods (FEM), high-performance compute, or distributed compute.

Benefits and Perks

• 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?
