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. That’s the deal.
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.
What We’re Looking For
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—you want a team that will invest in that growth, not throttle it.
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.
Nice to Have (genuinely nice-to-have — none of these are required, and we don’t expect any one candidate to have most of them)
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.
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
