Lead finance and accounting, including consolidated monthly, quarterly, and annual close, J-SOX controls, audits, treasury, payments, and FP&A for global subsidiaries.

About this role

Controller (head of finance and accounting) at Spider Labs (Spider AF), a global marketing-fraud-prevention SaaS startup with its Tokyo HQ plus offices in Lisbon, Cork and New York, strengthening its finance/accounting structure with capital markets in view.

As the domain owner for finance and accounting, the role consistently handles monthly, quarterly and annual closing, audit response, internal controls and FP&A, with the mission of not just running the close but building an IPO-ready disclosure and internal-control structure. The first ~90 days prioritize building the consolidated-closing structure (including overseas subsidiaries) and speeding up monthly close, establishing J-SOX internal controls and payment/approval controls, and building audit-firm relationships. The broader remit covers closing and disclosure (single-entity and consolidated, accounting policy and estimates), internal/financial controls (J-SOX, delegation-of-authority matrices, separation of preparer and approver, bank-balance reconciliation), audit and tax response, and later FP&A advancement. The execution layer combines internal staff, external accounting firms, dispatch staff and AI agents. Employment is full-time (正社員), primarily in-office in Minami-Aoyama, Tokyo, with remote negotiable. The posting is in Japanese.
