Controller

Atomic Semi • Austin, TX

12d • $180,000 - $210,000 • Onsite

About The Position

As Atomic Semi’s first dedicated accounting leader, this Controller will own the accounting function and build the financial foundations we need for our next stage of growth. This is a critical role with real scope, and the processes, systems, and controls you put in place will define how this company operates for years to come. You'll own all accounting operations from end-to-end. This includes running a clean, disciplined close process; building out manufacturing and inventory accounting; establishing controls and approval workflows; and driving audit readiness. You'll partner closely with Finance, Operations, and the broader business to ensure our accounting infrastructure keeps pace with how the company is scaling and what comes next. This is an autonomous, high-ownership role in a fast-moving environment. The right person is comfortable with ambiguity, motivated to create structure where little exists, and confident running the function independently.
