Proof Operator Banking Jobs in California (NOW HIRING)

Role Description

This is a full-time on-site role for an Assistant Controller, based in the San Francisco Bay Area. The Assistant Controller will build out the accounting function at a start up gaming Software company. The business has scaled rapidly and the accounting infrastructure needs to catch up – close process, controls framework, audit readiness, and team. You will own that build.

Day-to-day, you will own the close process end to end, design and enforce the internal controls framework, lead the company through its first audit, and build out revenue and wallet reconciliation workflows. This is a hands-on role – you will be in the detail while also standing up the processes and documentation that let the function scale.

You will report directly to the Corporate Controller & VP Accounting and oversee the accounting team as it grows.

Key Responsibilities

Core Accounting & Close

• Build and own a repeatable month-end close process from scratch, targeting a 5–7 day close cycle.
• Design and maintain the chart of accounts around products (Arcade, Rips) and key drivers (deposits, payouts, promotions, chargebacks, processor fees).
• Prepare, review, and approve journal entries, reconciliations, accruals, and adjustments.
• Standardize data imports, bank rules, and reconciliation workflows to maximize capacity before adding headcount.
• Own all general ledger and sub-ledger accounting.

Controls & Compliance

• Design and implement an internal controls framework that can withstand growth financing or external audit – documented policies, segregation of duties, system access controls, and approval workflows.
• Lead first audit preparation: PBC list management, auditor scheduling, and day-to-day relationship.
• Write and publish accounting policies and procedures.

Revenue, Wallet Integrity & AP

• Build and maintain a monthly and weekly player funds proof: wallet liability versus cash on hand, with exception reporting.
• Optimize accounts payable: implement vendor master management, approval flows, and spend limits using platforms such as Ramp and Bill.com.
• Manage AP end to end, including invoice processing, vendor payments, and 1099 compliance.

Data & Reporting

• Develop product-level P&Ls for Arcade and Rips (profitability by game, cohort, and channel).
• Partner with Growth and Data teams to establish a KPI source of truth.
• Deliver management reporting that supports operational and strategic decisions.

Team & Systems

• Manage and develop the accounting team as headcount grows.
• Evaluate current systems (QuickBooks Online) and lead future system implementations as the business scales (ERP, close management tools, AP automation).
• Support international expansion, including multi-entity general ledger structure and consolidation accounting.

Additional Scope

• Bank and treasury operations: daily cash position, bank reconciliations, cash flow inputs.
• Payroll accounting: salary allocations between departments and entities.

Required Qualifications

• CPA license or equivalent.
• Bachelor’s degree in Accounting, Finance, or related field.
• 8+ years of progressive accounting experience, with a meaningful portion in industry.
• Public accounting background (Big 4 or national firm) with audit experience.
• Has built an accounting function or team from scratch at least once.
• Close process ownership: has designed and run a month-end and year-end close, not just participated in one.
• Internal controls design and documentation.
• Has led or been the primary point of contact for an external audit.
• People management: has hired, trained, and managed accounting staff.
• Proficiency with financial software systems and tools such as QuickBooks Online, Ramp, and Excel.
• Multi-entity general ledger experience, including intercompany accounting and consolidations.
• On-site 5 days a week in San Francisco.

Preferred Qualifications

• Experience at a high-growth startup or scale-up where accounting infrastructure was immature.
• ASC 606 revenue recognition experience (implementation or ongoing ownership).
• SOX compliance experience (design or remediation, not just testing).
• System implementation experience (ERP migration, close management tools, AP automation).
• E-commerce, gaming, fintech, or digital platform business model exposure.
• Inventory accounting experience (LCNRV, cost flow methods, physical inventory controls).
• International or multi-entity consolidation experience.
• IFRS knowledge or experience with dual-reporting environments.

What Success Looks Like
