## Job description

Company Overview: Sustainment is an AI-native software platform that helps US-based manufacturers easily find and work with the critical suppliers they need to build and manage their supply chains. Our vision is to reimagine American manufacturing as a hyperconnected, secure, and resilient ecosystem of local and regional suppliers who can more easily connect, interact, and do business with the industry and government customers that rely on them. We are a dual-use technology platform that supports both DoD and commercial customers in pursuit of our vision.

Job Overview: We are seeking a highly skilled and hands-on Controller to lead our accounting and financial operations. This individual will be a critical member of the finance team, responsible for building scalable processes, ensuring compliance, and providing the financial visibility needed to support our rapid growth. The ideal candidate brings startup experience (Series A/B stage), strong technical accounting expertise, and the ability to thrive in a fast-paced, evolving environment.

For this position you must be local to Austin, TX and willing to be in office.

What you’ll bring:

- CPA required with strong technical accounting background.
- Startup finance experience at the Series A/B stage (experience building processes from scratch and scaling).

- Experience managing audits, tax filings, and compliance for a high-growth company.
- Strong systems orientation experience implementing or optimizing financial systems in a startup environment.
- Fluency with AI tools, particularly Claude, for budget vs. actuals commentary, ad hoc analysis, and other finance workflows. You use AI as a default productivity tool, know how to prompt it effectively, and apply sound judgment in validating the output before relying on it.
- Exceptional attention to detail, organizational skills, and ability to thrive in ambiguity.
- Collaborative, hands-on leader who can operate both strategically and tactically.

How you will lead:

- Own monthly budget vs. actuals analysis, partnering with budget owners to explain variances, identify key drivers, and incorporate changes into the next forecast.
- Oversee tax, compliance, and regulatory filings in coordination with external partners.
- Implement and optimize financial systems and tools to increase efficiency and accuracy.
- Mentor and build a high-performing accounting team as the company scales.
