Commanding and direct, comfortable setting expectations and enforcing standards
Intensely detail-driven — you notice what others miss and don’t let it slide
Fast-moving and decisive, able to execute under real pressure

Willing to challenge bad information, bad processes, and bad habits
Energized by accountability, complexity, and being the person everyone counts on
About the Role:
As a Controller, you’ll be the financial backbone for a portfolio of clients. You’ll command the close process, enforce rigor, and ensure financials are accurate, timely, and decision-ready.

You’ll also be expected to drive change, even when there’s resistance. That means leading system implementations, rolling out new processes, building automations, tightening controls, and ensuring audit readiness across multiple environments. You won’t just maintain what exists, you’ll fix what’s broken and raise the bar.
This role is ideal for someone who thrives in a fast-paced, high-accountability environment and takes pride in getting the details right—every time.
