Quilter is seeking a Senior/Staff Backend Engineer to join our File I/O Team. Your mission is to design and maintain the crucial bridges that allow seamless movement between Quilter and existing PCB CAD environments, combining deep backend engineering with the opportunity to learn new technical domains.

What You'll Do

Lead the design and development of integrations with CAD vendors’ scripting systems and file formats.
Define and extend Quilter’s internal PCB representation for compatibility across various 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 engineering best practices.
Mentor junior engineers and help shape the culture of the File I/O team.

What We're Looking For

5+ years of experience as a software engineer with significant time in backend roles.
Expert-level proficiency in Python.
Strong fluency in TypeScript/JavaScript, React, 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 like XML, JSON, or protobuf.
Exposure to hardware projects such as embedded systems, Arduino, or PCB tinkering.
Experience with cloud infrastructure (AWS, Docker, Kubernetes, Terraform).
Open-source contributions in developer tooling, CAD, or simulation software.
