Assistant Controller at GrowthxAI in United States

Job description

• Application
• We're hiring our first Assistant Controller to build and own the Accounting function at GrowthX. This is a 0-to-1 role: you're not inheriting a mature org, you're standing one up. You'll take the accounting infrastructure we have today — an outsourced bookkeeping firm, Campfire as our GL, and a lot of tribal knowledge walking out the door with our outgoing accounting lead — and turn it into a function that scales with the business and holds up under audit.
• You'll report to the Head of Finance and own the integrity of our books end to end: close, reporting, AR/collections, AP oversight, revenue recognition, systems, and controls. We currently lean on an outsourced accounting firm for bookkeeping — that's a stopgap, not the target state. Part of the job is to bring that work in-house and lower our dependence on outside help as the function matures, which means you should expect to be hands-on with the actual work, not just reviewing someone else's. You'll build the process, controls, and documentation so the next hire doesn't have to reverse-engineer any of it from Slack threads.
• GrowthX runs a hybrid model — subscription platform revenue alongside services revenue — so you'll work with revenue recognition that isn't a single, simple SaaS pattern. You'll also inherit real, live problems on day one: aging AR, contract structures with opt-out windows, multi-state tax exposure, and systems that don't yet talk to each other cleanly. We need someone who wants to fix that, not someone who needs it already fixed.

Responsibilities

• Own the monthly, quarterly, and annual close. We use an outsourced accounting firm for bookkeeping today; you'll direct that relationship in the near term while working to bring close, bookkeeping, and AP execution in-house over time.
• Prepare and ensure GAAP-compliant financial statements; analyze balance sheet and P&L movements and investigate variances before they reach leadership.
• Own AR and collections: invoicing, payment application, aging, and the direct customer follow-up that an outsourced team can't own — GrowthX carries meaningful past-due AR today, and closing that gap is part of the job, not an afterthought.
• Own AP oversight and vendor management, including approval workflows and vendor account hygiene.
• Work through complex accounting topics including ASC 606 revenue recognition, contract modifications, and billing structures, in a business with both subscription and services revenue.
• Own our core finance systems — Campfire (GL/AR/AP), Carta (equity), and our billing/payment stack — including the integration roadmap between them.
• Own the accounting processes, approval workflows, documentation, and internal controls a growing SaaS company needs, replacing ad hoc handling with something a new hire or an auditor could pick up cold.
• Review customer and vendor contracts for their accounting, billing, and revenue recognition implications, and translate negotiated terms into correct treatment.
• Own equity administration: option grant processing, cap table accuracy, and coordination with legal and the cap table system.
• Support treasury: cash positioning, inter-account transfers, and forecasting cash needs alongside the Head of Finance.
• Own tax and compliance coordination with external tax and legal advisors, including multi-state filings and notices.
• Partner with People Ops on payroll accounting, compensation changes, and compliance, working alongside our PEO.
• Prepare monthly reporting packages for our lender and investors.
• Build the audit-readiness muscle: documentation and controls that hold up the first time an external auditor asks a question, not just when the numbers happen to be right.

Requirements

• You might be a fit if you…
• Have prior experience as a Controller, or as a strong Assistant Controller / Accounting Manager ready to run the function independently, ideally at a high-growth Series A SaaS company.
• Have built or materially matured an accounting function before — you know what "0 to 1" actually requires: process, controls, and documentation that don't yet exist.
• Are deep in U.S. GAAP, including ASC 606 revenue recognition for subscription and services revenue, and can reason through a nonstandard revenue scenario instead of just applying a template.
• Are AI-forward: you use AI tools daily to move faster on close, reconciliations, and reporting, and you have a point of view on where automation belongs in an accounting workflow versus where it doesn't.
• Are comfortable owning the close independently — you can run it yourself without a controller above you catching your mistakes.
• Think like a business partner, not just an accountant: you can read a customer contract, a compensation change, or an operational decision and see the accounting and cash implications before anyone asks.
• Communicate clearly and directly — you can explain a judgment call to a non-finance exec in plain language and defend it if pushed.
• Are self-directed and comfortable with ambiguity. This is a remote, async, high-autonomy environment; nobody hands you a fully scoped process.
• Bonus points if…
• You've used Campfire, or a comparable modern GL (Ramp, Rippling, NetSuite, etc.), and can get productive fast.
• You've built an accounting function at a startup from the ground up, not just operated within one someone else built.
• You've worked in a hybrid subscription + services revenue model.
• You've insourced an accounting function that was previously outsourced, or transitioned a company off an outside bookkeeping firm.
• You've been through a first audit or a first institutional financing round and know what that scrutiny actually demands.
