Senior Accountant

The Role

We are hiring a Senior Accountant who will fully own Alt’s accounting and monthly close. You will be a one-person accounting team as we continue to grow our our finance and accounting org, operating independently while partnering closely with Operations, Lending, and Leadership. You will build the finance backbone for a fast growing marketplace: accelerate the close, own smarter spend, and give leadership clear, real-time visibility.

What You’ll Do Here:

• Own the monthly close end to end and deliver first-pass financials within five business days
• Run core reconciliations: cash and custodial wallets, seller payouts, payment processors, AR, AP, accruals, fixed assets, and key balance sheet accounts
• Maintain revenue and COGS recognition across auctions, fixed price, and lending in line with policy, including fees, refunds, and principal vs. agent considerations
• Own spend management: corporate cards and AP, vendor onboarding and master data, invoice routing and approvals, expense policy, receipt compliance, and month-end accruals
• Present to leadership a weekly with concise commentary and trend charts, and deliver a month end Leadership Pack with P&L, balance sheet, cash, and flux analysis that highlights drivers, risks, and recommended actions
• Be the primary liaison to tax accountants and auditors: own audit and tax calendars, walkthroughs, sample requests, and timely responses; coordinate federal and state income and franchise filings, and 1099 compliance
• Maintain accounting policies, close checklists, reconciliations, and an approvals matrix; strengthen controls and documentation

This is a perfect fit if you…

• Take full ownership, communicate proactively, and like turning ambiguity into structure
• Enjoy building clean reconciliations and scalable checklists that others can follow
• Balance accuracy with speed and know when to ship, iterate, or escalate
• Prefer automation to repetition and can stand up simple tooling without a big team

What You Bring to the Table:

• 4 to 7 years in public accounting and industry or equivalent startup experience
• Hands-on ownership of monthly close in a lean environment and strong US GAAP knowledge
• Reconciliation expertise across cash, wallets, payouts, processors, AR, AP, accruals, and reserves
• Spend management experience with Ramp or similar tools for cards and AP, including policy and approvals administration
• Experience owning external tax and audit relationships and leading PBC workflows
• Tools: QuickBooks Online, Stripe, banking portals; Google Workspace, Notion, Slack; Ramp
• Lending accounting exposure and reserve methodologies; experience with debt facility reporting

What You’ll Get From Us:

• Hands-on exposure to both accounting and finance processes with growth opportunities ahead
• A chance to own the function and build the foundation for scale
• $100/month work-from-home stipend
• $200/month wellness stipend
• WeWork office stipend
• 401(k) retirement benefits
• Flexible vacation policy
• Generous paid parental leave
