Software Engineer - Test Automation (SDET)

At Mach9, Test Automation Engineers protect the workflows that civil engineers and surveyors rely on when they work in our browser-based 3D CAD platform. Coding agents do a growing share of our development work, but that only works when we have automated checks that return fast, trustworthy answers. You'll own the accuracy of those answers — giving us coverage that spans from data upload to deliverable export — and the test infrastructure it runs on.

This role is ideal for engineers who have built and maintained automated test suites for production web applications and can chase a failure through app code and infrastructure all the way to its root cause.
