Controller

Who you are

• 8+ years of progressive accounting experience, including hands-on controllership in industry
• Deep US GAAP knowledge, with direct experience converting a company from cash or mixed-basis accounting to full accrual
• Proven ownership of an external audit relationship — PBC lists, walkthroughs, sample testing, and auditor communication
• Experience in a marketplace, fintech, or lending environment, with comfort in principal-vs-agent revenue questions and reserve/receivable accounting
• Fluency with QuickBooks, a modern spend platform (e.g., Ramp), an HRIS (e.g., Rippling), and enough SQL/BI comfort to tie GL entries back to source data, ideally including running an integration between a data warehouse and an accounting system
• Experience managing an outsourced, fractional, or offshore accounting team
• Nice to have: asset-backed lending or covenant/borrowing-base reporting, and experience preparing a company for institutional fundraising or M&A diligence

What the job involves

• We are hiring a Controller to build and own Alt's accounting function for the first time. Today Finance is a one- person team supported by an outsourced accounting provider — you will bring that function in-house, close out our external audit, lead our conversion to full US GAAP accrual accounting, and take ownership of tax and systems work, reporting directly to the Head of Finance
• Alt is fully remote (US), and this is a build-from-scratch role at an early-stage company: you’ll write the policies, checklists, and controls Alt has never had, and grow a small team behind you as volume scales. If you want to own a function end-to-end rather than inherit one, this is that job
• Own the monthly close end-to-end and drive it toward a 5-day, fully reconciled, audit-ready close, with nothing aged past 30 days
• Lead the conversion from mixed cash/accrual to full US GAAP accrual across every revenue stream: auctions, the fixed-price exchange, lending and cash advances, and partner revenue
• Own the chart of accounts and revenue recognition policy, and lead the work to tie GL entries back to our source-of-truth data warehouse (e.g., Snowflake) and feed it directly into QuickBooks or a future ERP, so revenue postings stop being a manual month-end exercise
• Be the primary point of contact for our external auditors: own the PBC list, walkthroughs, and full close-out of open items
• Own the tax compliance calendar (corporate and fund-level returns, K-1s, state and local filings, 1099s, and the annual R&D credit study), working with outside tax advisors
• Own covenant and borrowing-base reporting for our asset-backed credit facility, partnering with the Head of Finance on lender compliance
• Own day-to-day accounting operations (AP/AR, reconciliations, fixed assets, spend controls, and corporate card and vendor administration), and manage our outsourced provider with a mandate to bring the work in-house over time
