Résumé du poste

Formlabs is seeking a mid-to-senior IC to advance testing for PreForm. You will own performance regression detection, re-architect systemtest layers for the Local API, and manage large-scale corpus testing of customer models to prevent regressions.

You will also own crash analytics and CI/test infrastructure stewardship. The role requires strong C++ and Python skills, deep CI/CD expertise, and experience with desktop GUI testing on Windows/macOS.

Qualifications

• Proficient in C++ for integration and system tests against PreForm internals.
• Python for tooling, pipelines, and result diffing.
• Strong CI/CD and automation experience (Jenkins, parallelization, flake management).
• Experience with observability tools (Sentry, dashboards) and diagnosing release health.
• GUI automation or desktop testing experience (Windows/macOS) with Squish/Qt Test beneficial.

Responsabilités

• Own performance regression detection across PRs and nightly runs with KPI monitoring.
• Lead systemtest re-architecture for PreForm Local API and end-to-end headless testing.
• Build pipelines to test large batches of customer models, diffs vs baselines for regressions.
• Own crash intelligence: Sentry triage, trending, and reproduction harnesses.

Description du poste

Do you want to change how the world creates?

At Formlabs, we're building the tools that make it possible for anyone to bring their ideas to life, from cutting-edge products to life-saving medical devices. Our 3D printing technology powers innovation at more than 50,000 industry leaders worldwide, including Apple, Google, Tesla, New Balance, and NASA. Together, we're helping everyone design, prototype, and manufacture faster than ever before.

In this role you will help building and shipping PreForm, own PreForm's quality and performance signal - make quality automated, measurable, and enforced at the PR gate. We're a team of hands-on builders, engineers, and innovators reinventing how the world makes physical things. If you're ready to shape the future of fabrication, come build it with us.

The Job:

• Performance regression detection. Per-PR and nightly measurement of the defined KPIs (startup, upload, print generation, crash rate) in CI, with alerting on regression. This is the enforcement mechanism for the PreForm performance initiative.
• Systemtest re-architecture on the PreForm Local API. Rebuild the systemtest layer to drive end-to-end scenarios headlessly through PreForm Server, in alignment with the API team.
• Customer-file corpus testing. Build and own a pipeline that runs large batches of real customer models through slicing and support generation and diffs results against baselines - catching regressions on the geometry customers actually print, at a scale manual testing cannot reach.
• Crash intelligence. Own Sentry triage, trending, and root-cause attribution; build crash-reproduction harnesses so engineers fix rather than investigate.
• Test infrastructure stewardship. Print regression baselines, CI flake, test runtimes, golden-file management - owned as a product instead of taxing feature engineers.

You:

• C++ proficiency. Able to write integration and system tests against PreForm internals and understand what they exercise (mesh operations, print file generation, slicing output). Not necessarily a geometry expert; not afraid of the codebase.
• Python for tooling and harnesses. Corpus pipelines, API-driven test drivers, result diffing and reporting.
• CI and automation depth. Jenkins, test parallelization, flake management, baseline/golden-file testing strategies.
• Observability instinct. Sentry, Amplitude, crash and performance dashboards. Treats 'is this release healthy' as a data question.
• Desktop application testing experience (strong plus). GUI automation on Windows/macOS (Squish or Qt Test-based harnesses)
• Seniority: mid-to-senior IC. Senior enough to define the test strategy independently; hands-on enough to build it. Real IC appetite.

Bonus Skills:

• Passion for 3D printing and emerging technologies
• Experience in a fast-growing startup environment

We Offer:

• Hybrid work
• Catered lunch at the office 3 days per week
• Private health insurance with Medicare (Blue package + hospital coverage)
• A monthly or quarterly public transportation pass for Budapest
• Shares in the company (we're a double unicorn company!)
• Free beverages and snacks at the office
• All You Can Move sports pass with 9500 HUF monthly allowance
• Free 3D prints
• An inclusive, dog-friendly office with diverse and inspiring colleagues
• Development opportunities both in-house and off-site
• Free team events
