what is first chamber build and test apps lab

First Chamber Build & Test happens in the Applied lab (the Apps lab) before a new product ever ships. You assemble and build the first chamber of a new platform, then run it through testing to find and fix issues — or escalate them to Engineering — before Manufacturing builds production units and before it reaches a customer. WHY IT MATTERS: it's where a GPS engineer earns their 'owns the product' credibility. You are the first person to see how the product actually behaves, so you find the problems early, document them, and feed them back. Your angle: this is where your hands-on systems-engineering background (root-cause, controlled experiments) pays off — you catch issues early and turn them into fixes + docs before the product is in the field.
