<h1>About Quilter</h1><p style="min-height:1.5em"></p><p style="min-height:1.5em">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.</p><p style="min-height:1.5em">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:</p><ol style="min-height:1.5em"><li><p style="min-height:1.5em">Focus on the mission</p></li><li><p style="min-height:1.5em">Build great things that help humans</p></li><li><p style="min-height:1.5em">Demonstrate grit</p></li><li><p style="min-height:1.5em">Never stop learning</p></li><li><p style="min-height:1.5em">Pursue excellence</p></li></ol><p style="min-height:1.5em"></p><p style="min-height:1.5em">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.</p><p style="min-height:1.5em">This is a genuinely AI-native team—and we'll make you <em>dangerous</em> with it. A lot of companies say "we use AI." Here, we will pay for you to master it:</p><ul style="min-height:1.5em"><li><p style="min-height:1.5em">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.</p></li><li><p style="min-height:1.5em">Run real model evals on our actual problems—not vibes or Twitter threads.</p></li><li><p style="min-height:1.5em">Develop genuine craft in prompting, context engineering, and MCP server design—skills that compound over your whole career.</p></li><li><p style="min-height:1.5em">Operate with the leverage of a team of ten. Work that used to require a squad of engineers, you'll learn to ship solo.</p></li><li><p style="min-height:1.5em"><em>You'll leave this job a substantially more capable engineer than you arrived.</em> <strong>That's the deal.</strong></p></li></ul><p style="min-height:1.5em"></p><p style="min-height:1.5em"><strong>What You'll Do</strong></p><ul style="min-height:1.5em"><li><p style="min-height:1.5em">Build and extend integrations with CAD vendors' file formats and scripting systems.</p></li><li><p style="min-height:1.5em">Reverse-engineer proprietary binary and text-based formats, with support from senior engineers.</p></li><li><p style="min-height:1.5em">Help shape Quilter's internal PCB representation as we expand support for new tools.</p></li><li><p style="min-height:1.5em">Write robust, well-tested code that holds up against messy real-world customer data.</p></li><li><p style="min-height:1.5em">Use—and help build—the next generation of agent-powered workflows for CAD reverse engineering.</p></li><li><p style="min-height:1.5em">Own features end-to-end: design, implementation, testing, rollout.</p></li></ul><p style="min-height:1.5em"></p><p style="min-height:1.5em"><strong>What We're Looking For</strong></p><ul style="min-height:1.5em"><li><p style="min-height:1.5em">3-7 years of software engineering experience, with meaningful backend or systems work.</p></li><li><p style="min-height:1.5em">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.</p></li><li><p style="min-height:1.5em">Genuine excitement about coding agents and a real hunger to get great at them—you want a team that will invest in that growth, not throttle it.</p></li><li><p style="min-height:1.5em">Comfort with ambiguous, reverse-engineering-flavored problems: unfamiliar code, undocumented formats, weird edge cases.</p></li><li><p style="min-height:1.5em">General knowledge of binary formats.</p></li><li><p style="min-height:1.5em">Solid fundamentals in design, testing, and debugging.</p></li><li><p style="min-height:1.5em">Strong communication and high ownership in a fast-moving startup environment.</p></li></ul><p style="min-height:1.5em"></p><p style="min-height:1.5em"><strong>Nice to Have</strong> (genuinely nice-to-have — none of these are required, and we don't expect any one candidate to have most of them)</p><ul style="min-height:1.5em"><li><p style="min-height:1.5em">A little C or C++ — not required at all, but occasionally helpful for skimming vendor SDKs or binary formats.</p></li><li><p style="min-height:1.5em">Familiarity with PCB / EDA / CAD workflows or hardware tinkering.</p></li><li><p style="min-height:1.5em">Experience with binary or large-scale serialization formats (protobuf, custom binary, XML, JSON).</p></li><li><p style="min-height:1.5em">Experience building tooling around coding agents (evals, harnesses, MCP servers, etc.).</p></li><li><p style="min-height:1.5em">Cloud infra (AWS, Docker, Kubernetes, Terraform).</p></li><li><p style="min-height:1.5em">Open-source contributions in developer tooling, CAD, or simulation.</p></li></ul><p style="min-height:1.5em"></p><p style="min-height:1.5em"><strong>Please note</strong>: 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.</p><p style="min-height:1.5em"></p><h1>What we offer:</h1><ul style="min-height:1.5em"><li><p style="min-height:1.5em">Interesting and challenging work</p></li><li><p style="min-height:1.5em">Competitive salary and equity benefits</p></li><li><p style="min-height:1.5em">Health, dental, and vision insurance</p></li><li><p style="min-height:1.5em">Regular team events and offsites (~4x / year)</p></li><li><p style="min-height:1.5em">Unlimited paid time off</p></li><li><p style="min-height:1.5em">Paid parental leave </p></li></ul><p style="min-height:1.5em">Want to learn more about Quilter, our vision, and our investors?
