Job summary

Quilter is building automation for PCB design, helping electrical engineers save time and effort. This role focuses on resolving customer blockers, shipping integration features, and verifying end-to-end design workflows.

You will work with Python, parsers, and CAD tooling, while improving diagnostics, tooling, and customer handoffs. Collaboration with GTM and engineering is essential to prioritize blockers and deliver lasting improvements.

Qualifications

• Deep production Python experience, ownership from design through testing and rollout.
• Experience working directly with customers, partners, or technical users to diagnose workflows and deliver working software.
• Strong debugging skills across unfamiliar code and data; test hypotheses with limited information.
• Clear communication and sound judgment under time pressure.

Responsibilities

• Investigate and resolve customer blockers; reproduce failures and identify causes.
• Ship integration features and fixes; own Python changes from design through rollout.
• Verify the complete design workflow; turn cases into acceptance checks and regression tests.

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:

1. Curiosity

2. Conviction

3. Rigor

WHAT YOU’LL DO

• Investigate and resolve customer blockers. Work with customers and GTM to reproduce failures, inspect design data and logs, and identify the cause. Fix File I/O issues and coordinate with partner teams when a problem crosses system boundaries.
• Ship integration features and fixes. Own Python changes from design through rollout, including parsers, exporters, and shared representations of boards, schematics, and constraints. Make sound implementation tradeoffs and contribute through code reviews.
• Verify the complete design workflow. Turn representative customer cases into acceptance checks and regression tests. Validate that design information survives import and that exported results remain usable in the customer’s native CAD tool.
• Turn recurring problems into better tooling. Improve diagnostics and error messages, automate reproductions, and build agentic investigation workflows. Use evaluations and feedback loops to make troubleshooting faster and more reliable.
• Connect customers’ existing workflows to Quilter. Build reusable scripts and integrations for design-data preparation and handoffs. Use repeated customer needs to identify capabilities worth supporting in the shared product.
• Work closely with GTM and engineering. Help the team prioritize urgent blockers and larger improvements, agree on scope and commitments, and explain findings clearly. Pair with customers, demonstrate fixes, and document workflows they can use independently.

WHAT WE’RE LOOKING FOR

• Deep production Python experience, with ownership of maintainable software from design through testing and rollout.
• Experience working directly with customers, partners, or technical users to understand a workflow, diagnose integration problems, and deliver working software.
• Strong debugging skills across unfamiliar code, files, and structured data. You can isolate causes and test hypotheses with incomplete information.
• Clear communication and sound judgment under time pressure. You explain uncertainty, coordinate priorities and dependencies, and follow through on both immediate fixes and lasting improvements.
• Practical experience with LLMs and agentic workflows, including evaluating results and improving the tools and feedback loops around them.

NICE TO HAVE

• Hands-on familiarity with PCB design workflows and ECAD tools.
• Experience with parsers, proprietary file formats, vendor APIs, or CAD scripting.
• Experience in customer or integration engineering, including troubleshooting in environments with restricted access to systems or design data.
• Experience building regression corpora, diagnostic tools, or agent harnesses and evals.

WHAT SUCCESS LOOKS LIKE

Customer blockers turn into verified production improvements. More designs move successfully through import, Quilter, and native export; recurring failures decrease, and the tests, diagnostics, and workflow tools you build help the whole team resolve the next issue faster.

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
• Paid parental leave
