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

Quilter•Los Angeles, CA

8d•Hybrid

About The Position

Quilter is seeking 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 tools including Altium, KiCad, Cadence Allegro, and Siemens Xpedition, preserving design intent as files move into Quilter and results return to customers’ CAD workflows. The role works primarily in Python on parsers, exporters, design models, diagnostics, and workflow automation. The engineer will address both urgent customer blockers and broader improvements in CAD coverage and fidelity. They will also build workflows using LLMs and agents to investigate failures, identify recurring patterns, and automate repetitive integration work, with reliable checks on results. The position is hybrid and 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, enabling more designs to move successfully through import, Quilter, and native export, reducing recurring failures, and building tests, diagnostics, and workflow 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, and identify causes of customer blockers.
Fix File I/O issues and coordinate with partner teams when problems cross system boundaries.
Own Python changes from design through rollout, including parsers, exporters, and shared representations of boards, schematics, and constraints.
Make implementation tradeoffs and contribute through code reviews.
Turn representative customer cases into acceptance checks and regression tests.
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 between customers’ existing workflows and Quilter.
Use repeated customer needs to identify capabilities worth supporting in the shared product.
Help the team prioritize urgent blockers and larger improvements, agree on scope and commitments, and communicate findings clearly.
Pair with customers, demonstrate fixes, and document workflows they can use independently.
