Key facts

What you'll do

• Lead the performance regression detection process by measuring key performance indicators (KPIs) such as startup time, upload speed, print generation, and crash rates during continuous integration (CI) cycles, ensuring timely alerts for any regressions.
• Re-architect the system test framework for the PreForm Local API, enabling comprehensive end-to-end testing scenarios that align with the API team's objectives.
• Develop and manage a testing pipeline that utilizes real customer files to run extensive batches through slicing and support generation, allowing for the detection of regressions in geometry that customers typically print.
• Oversee crash intelligence initiatives by managing Sentry triage processes, identifying trends, and attributing root causes; create crash-reproduction tools to facilitate prompt fixes by engineers.
• Take ownership of test infrastructure, including managing print regression baselines, addressing CI flakiness, optimizing test runtimes, and overseeing golden-file management as a product.
• Collaborate closely with cross-functional teams to ensure that quality and performance standards are met and maintained throughout the development lifecycle.
• Contribute to the continuous improvement of testing methodologies and practices, ensuring that they are scalable and effective in catching issues early in the development process.
