Job description

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 a Backend Engineer to join our File I/O Team. This group integrates Quilter with the world’s leading PCB CAD vendors—such as Altium, Cadence Allegro, Siemens Xpedition, and Zuken. You’ll design and maintain the critical bridges that let engineers move seamlessly between Quilter and existing CAD environments.

In this role, you’ll combine deep backend engineering skills with the ability to quickly learn new technical domains—from parsing and generating complex CAD formats to managing Quilter’s internal “board” model. As a senior member of the team, you’ll shape technical direction, mentor others, and own high‑impact projects end‑to‑end.

What You’ll Do

• Lead design and development of integrations with CAD vendors’ scripting systems and file formats.
• Define and extend Quilter’s internal PCB representation for compatibility across tools.
• Build robust APIs and backend services to abstract away CAD complexity for downstream teams.
• Collaborate with ML, EDA, and electrical engineering experts to ensure seamless interoperability.
• Provide technical leadership on architecture, testing, and best practices.
• Mentor junior engineers and help shape the culture of the File I/O team.

What We’re Looking For

• 3+ years of experience as a software engineer, with significant time in backend roles.
• Expert‑level proficiency in Python (required) and modern backend frameworks.
• Proven experience leading complex integration projects or working with large/ambiguous data models.
• Strong system design skills, including API design and distributed system reliability.
• Excellent collaboration and communication skills, with a track record of cross‑functional influence.
• Ability to thrive in a fast‑moving, high‑ownership startup environment.

Nice to Have

• Familiarity with PCB design workflows or EDA/CAD systems.
• Experience working with large‑scale data serialization formats (XML, JSON, protobuf).
• Exposure to hardware projects (embedded systems, Arduino, PCB tinkering).
• Experience with cloud infrastructure (AWS, Docker, Kubernetes, Terraform).
• Open‑source contributions in developer tooling, CAD, or simulation software.

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
