Software Engineer — AI-Native CAD Integrations

Quilter; United States; Remote; USD 90,000 - 130,000; Full time

Job summary

Quilter is building an AI-native File I/O team to automate PCB design tasks and accelerate engineering workflows. You’ll work primarily in a Python codebase to parse, translate, and generate complex CAD formats, mapping them into Quilter's internal board model.

The role focuses on reverse-engineering binary and text-based formats, enhancing tool support, and shipping robust features end-to-end with a small, focused team.

Qualifications

• 3-7 years of software engineering experience, with meaningful backend or systems work.
• Strong Python proficiency and production code experience.
• Genuine excitement about coding agents and a growth mindset.

Responsibilities

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

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:

• Focus on the mission
• Build great things that help humans
• Demonstrate grit
• Never stop learning
• Pursue excellence

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. 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
