Senior Accountant

A2Z Sync • Denver, CO

22h • Hybrid

About The Position

A2Z Sync is seeking a Senior Accountant to partner closely with the Controller during a period of rapid growth. This is an execution-focused role where the individual will own the day-to-day rhythm of the close, run reconciliations independently, and bring discipline to core accounting workflows. The role is designed to free the Controller to focus on technical accounting, audit, equity, tax, and strategic finance while the Senior Accountant keeps the financial engine running cleanly and on time. This is a high-ownership seat for someone who wants real responsibility, exposure to the full stack of accounting at a Series B SaaS company, and a clear path to grow as the team scales. The role requires 2-3 days per week in the Denver office.

Requirements

• Bachelor's degree in accounting or finance.
• 3–5 years of progressive accounting experience with a strong foundation in full-cycle GL accounting.
• Solid working knowledge of U.S. GAAP and accrual-basis accounting.
• Hands-on experience with at least one cloud accounting system (Rillet, NetSuite, Sage Intacct, or similar).
• Advanced Excel / Google Sheets (pivot tables, XLOOKUP / INDEX-MATCH, large data manipulation).
• Demonstrated ability to run a monthly close independently, hit deadlines, and produce audit-ready workpapers.
• Comfort with a fast-paced, AI-forward environment — you actively use AI tools in your workflow and look for ways to automate the repetitive.
• Strong organizational skills and the ability to juggle competing priorities without dropping balls.

• CPA license or active CPA candidate.
• Prior experience at a high-growth startup, technology company, or SaaS environment.

• Investigate and clear reconciling items without prompting.
• Prepare month-over-month and budget-to-actual variance analyses for key P&L and balance sheet accounts; draft commentary for the Controller's review.
• Review, code, and process vendor bills in Ramp with proper GL coding and approval routing.

• Compile data, prepare workpapers, and assist with timely sales & use tax filings across multiple states.
