You'll report to finance leadership and work closely with the CEO, CFO/VP of Finance, FP&A, HR, and outside auditors and tax advisors.

This is a hands-on role for an experienced accounting leader who has run month-end close and built controls in a SaaS environment, is comfortable being the primary owner of the books, and wants to build out the finance function's foundation as the company grows.

• Manage day-to-day accounting operations, including accounts payable, accounts receivable, payroll accounting, revenue recognition, and general ledger.
• Design, implement, and maintain internal controls and accounting policies appropriate for a scaling SaaS business.
• Own revenue recognition for subscription/SaaS contracts in accordance with ASC 606, partnering with Sales and Legal on contract structuring.
• Manage relationships with external auditors, tax advisors, and banking partners, and lead the annual audit process.
• Ensure timely and accurate tax compliance (federal, state, sales/use tax) in partnership with outside tax advisors.
• Partner with FP&A on budgeting, forecasting, and variance analysis, ensuring the books support accurate financial planning.
• Manage cash flow, treasury operations, and banking relationships, including monitoring runway and burn rate.
• Build and improve accounting systems and processes (e.g., ERP/accounting software, expense management, billing) to support scale.
• Support due diligence and reporting needs tied to fundraising, board reporting, and potential M&A activity.
• Hire, manage, and develop accounting staff as the team grows.

Requirements

• 8+ years of progressive accounting experience, including at least 3 years in a Controller or similar leadership role.
• Experience in B2B SaaS or software, with a strong understanding of ASC 606 revenue recognition for subscription businesses.
• CPA required.
• Proven experience owning the full close process and producing accurate, timely GAAP financial statements.
• Experience designing and maintaining internal controls, ideally including experience preparing for or supporting a SOC 2 or similar audit.
• Hands-on experience managing external audits and working with outside tax advisors.
• Proficiency with modern accounting/ERP systems (e.g., NetSuite, QuickBooks, Sage Intacct) and billing/subscription management tools.
• Strong analytical and organizational skills, with high attention to detail and a bias toward clean, well-documented processes.
• Excellent communication skills, with the ability to explain financial results and controls to non-finance stakeholders.
• Based in or near Boston, MA.

Nice to Haves

• Experience at a venture-backed startup, including supporting fundraising due diligence and board reporting.
• Prior public accounting experience (Big 4 or regional firm) before moving in-house.
• Experience implementing or migrating accounting/ERP systems as a company scales.
• Familiarity with equity accounting and cap table management (e.g., Carta).
