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

Quilter•Los Angeles, CA

10d•Hybrid

About The Position

Quilter is hiring a Senior Software Engineer to work directly with its go-to-market team and customers to turn integration blockers into production fixes and features. The File I/O team connects Quilter with Altium, KiCad, Cadence Allegro, Siemens Xpedition, and other tools, preserving design intent as files enter Quilter and results return to customers’ CAD workflows. The role focuses primarily on Python development involving parsers, exporters, design models, diagnostics, and workflow automation. The engineer will address urgent customer issues while contributing to broader improvements in CAD coverage and fidelity. They will also develop LLM- and agent-based workflows to investigate failures, identify recurring patterns, and automate repetitive integration work, with reliable checks on results. This is a hybrid role based out of Quilter’s Long Beach, California office, with regular in-person collaboration alongside the go-to-market team. Success means turning customer blockers into verified production improvements, helping more designs move successfully through import, Quilter, and native export, reducing recurring failures, and building tools that help the team resolve future issues faster.

Requirements

Deep production Python experience, including ownership of maintainable software from design through testing and rollout.
Experience working directly with customers, partners, or technical users to understand workflows, diagnose integration problems, and deliver working software.
Strong debugging skills across unfamiliar code, files, and structured data, including the ability to isolate causes and test hypotheses with incomplete information.
Clear communication and sound judgment under time pressure, including explaining uncertainty, coordinating priorities and dependencies, and following through on 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 Haves

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 evaluations.

Responsibilities

Work with customers and the go-to-market team to reproduce failures, inspect design data and logs, identify causes, fix File I/O issues, and coordinate with partner teams when problems cross system boundaries.
Own Python integration changes from design through rollout, including parsers, exporters, and shared representations of boards, schematics, and constraints; make implementation tradeoffs and contribute to code reviews.
Create acceptance checks and regression tests from representative customer cases, and validate that design information survives import and exported results remain usable in customers’ native CAD tools.
Improve diagnostics and error messages, automate reproductions, and build agentic investigation workflows; use evaluations and feedback loops to make troubleshooting faster and more reliable.
Build reusable scripts and integrations for design-data preparation and handoffs, and identify recurring customer needs that warrant shared product capabilities.
Work with go-to-market and engineering teams to prioritize blockers and larger improvements, agree on scope and commitments, communicate findings, pair with customers, demonstrate fixes, and document workflows.
