Software Engineer - AI-Native CAD Integrations

Role Description

Quilter's File I/O team builds the bridges between Quilter and the world's leading PCB CAD tools—Altium, Cadence Allegro, and Siemens Xpedition. You'll work primarily in our Python File I/O codebase: parsing, translating, and generating complex (and often undocumented) CAD formats, and mapping them into Quilter's internal "board" model.

This is a genuinely AI-native team—and we'll make you dangerous with it. A lot of companies say "we use AI." Here, we will pay for you to master it:

• Build your own agent harnesses for the kind of reverse-engineering we do—parsing undocumented binary formats, mapping vendor schemas, automating the tedious parts of integration work.
• Run real model evals on our actual problems—not vibes or Twitter threads.
• Develop genuine craft in prompting, context engineering, and MCP server design—skills that compound over your whole career.
• Operate with the leverage of a team of ten. Work that used to require a squad of engineers, you'll learn to ship solo.
• You'll leave this job a substantially more capable engineer than you arrived.

What You'll Do:

• Build and extend integrations with CAD vendors' file formats and scripting systems.
• Reverse-engineer proprietary binary and text-based formats, with support from senior engineers.
• Help shape Quilter's internal PCB representation as we expand support for new tools.
• Write robust, well-tested code that holds up against messy real-world customer data.
• Use—and help build—the next generation of agent-powered workflows for CAD reverse engineering.
• Own features end-to-end: design, implementation, testing, rollout.

Qualifications

• 3-7 years of software engineering experience, with meaningful backend or systems work.
• Strong Python proficiency. This is the language you'll spend nearly all your time in, and real expertise here matters more than anything else on this list.
• A track record of writing clean, maintainable code in real production codebases.
• Genuine excitement about coding agents and a real hunger to get great at them.
• Comfort with ambiguous, reverse-engineering-flavored problems: unfamiliar code, undocumented formats, weird edge cases.
• General knowledge of binary formats.
• Solid fundamentals in design, testing, and debugging.
• Strong communication and high ownership in a fast-moving startup environment.

Requirements

• A little C or C++ — not required at all, but occasionally helpful for skimming vendor SDKs or binary formats.
• Familiarity with PCB / EDA / CAD workflows or hardware tinkering.
• Experience with binary or large-scale serialization formats (protobuf, custom binary, XML, JSON).
• Experience building tooling around coding agents (evals, harnesses, MCP servers, etc.).
• Cloud infra (AWS, Docker, Kubernetes, Terraform).
• Open-source contributions in developer tooling, CAD, or simulation.

Benefits

• 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
