Accounting Manager

About the role

Sustainment is an AI-native software platform that helps US‑based manufacturers find and work with critical suppliers to build and manage their supply chains. The company envisions a hyperconnected, secure, and resilient ecosystem of local and regional suppliers that can easily connect with industry and government customers. As a dual‑use technology platform, Sustainment supports both DoD and commercial customers. We are hiring an Accounting Manager to run our day‑to‑day accounting operations. Our finance stack is built and operating — QuickBooks Online, Ramp, and Anrok — with documented processes and a clean close. You will own the month‑end close, general ledger integrity, and the transactional accounting cycle, reporting directly to the CFO. This is a hands‑on role for someone who takes pride in a fast, clean close and does not need to be told when the calendar is slipping. For this position you must be local to Austin, TX and willing to be in office a minimum of 3 days a week.

Responsibilities

• Run the monthly close end to end.
• Own the close calendar and deliver financials within 10 business days, with a path to tightening that as you ramp.
• Own general ledger integrity, including journal entries, account reconciliations, and accruals.
• Manage the full transactional cycle: accounts payable, accounts receivable, expense management, and payroll accounting.
• Apply established revenue recognition policy across both commercial and government contracts, including billing and revenue schedules.
• Produce the monthly reporting package and supporting schedules that feed board and investor reporting.
• Own monthly budget vs. actuals analysis, partnering with budget owners to explain variances, identify key drivers, and incorporate changes into the next forecast.
• Administer and optimize our finance stack — QuickBooks Online for the GL, Ramp for spend and AP, Anrok for sales tax.
• Own sales tax compliance, including nexus monitoring, registrations, and filings across jurisdictions.
• Maintain and improve the documented accounting policies, procedures, and internal controls already in place.
• Prepare audit‑ready schedules and support requests; serve as the primary preparer for the annual audit under CFO direction.
• Coordinate with external tax and compliance partners on filings and information requests.
• Identify what's slow, manual, or error‑prone in the current process and fix it.

Requirements

• 4–6 years of progressive accounting experience, including 1–2 years owning a monthly close.
• Working knowledge of U.S. GAAP and internal controls, with the judgment to know when a transaction needs to escalate.
• Public accounting or audit experience (Big 4 or national firm preferred).
• CPA or CPA candidate preferred.
• Startup or high‑growth company experience, ideally Series A/B.
• Hands‑on experience with QuickBooks Online and modern spend and tax automation tools.
• Fluency with AI tools, particularly Claude, for budget vs. actuals commentary, ad hoc analysis, and other finance workflows.
• Multi‑state sales tax compliance experience, particularly for SaaS.
• Government or federal contract accounting exposure is a strong plus.
• Precision, deadline discipline, and follow‑through.
• Direct communicator who works well with a small team and operates without heavy oversight.
