Senior/Staff Software Engineer, Customer Integrations — PCB/CAD

Quilter is hiring a Senior Software Engineer to work with its go-to-market team and customers on production fixes and features for integrations with PCB/CAD tools. The role focuses on Python-based parsers, exporters, design models, diagnostics, workflow automation, and agentic tools that improve customer troubleshooting and design-file workflows.

Responsibilities:

• 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

Requirements:

• 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
• 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
