Senior Accountant (Accounting Lead)

Rox is building the AI-native revenue operating system for modern go-to-market teams. Backed by Sequoia, GV, and General Catalyst, we work with ambitious companies to replace fragmented CRM workflows with intelligent, autonomous systems that actually drive outcomes.

We are a fast-moving Series A company (~75 people) operating at the intersection of data, AI, and real revenue execution. We care deeply about technical rigor, customer truth, and building systems that scale with clarity.

Rox Finance is a lean, high-ownership team responsible for keeping the company financially disciplined while enabling fast growth. We’re building stronger operating rhythm over time—faster close execution, higher accounting quality, and scalable foundations that make decision-making more reliable as we grow.

This Senior Accountant role is a foundational hire in that journey. You’ll be our internal close captain and accounting quality owner, partnering with our external accounting firm while we bring more core accounting ownership in-house.

Rox is hiring a Senior Accountant to lead month-end close, enforce accounting standards, and apply sound accounting judgment so our financials are fast, accurate, and audit-ready. You’ll be the primary in-house owner of close outcomes, running close governance and review gates while our external firm provides production support. This role is in-office, five days a week.

Our stack includes QuickBooks Online (QBO), Ramp, and vendor portals for usage-based spend. We’re looking for someone with a software/SaaS accounting background—comfortable with subscription revenue mechanics (deferred revenue and revenue schedules) and accrual/deferral discipline for operating expenses.

The work is close-first and hands-on: you’ll own accruals, reconciliations, and core schedules, and you’ll coordinate cross-functionally to keep inputs clean (partnering with Finance Ops as it comes online). You’ll also work with Engineering and technical owners to build repeatable accrual methods for usage-based AI and cloud vendors (LLM providers, AI Search API providers, and infrastructure such as AWS/Azure/GCP, Snowflake, and Fivetran).

Own month-end close leadership

• Run the close calendar end-to-end: checklist, timelines, owners, and SLAs with the external accounting firm and internal stakeholders.

• Drive close execution and accountability: daily close standups during close, escalation paths for bottlenecks, and a clear definition of done for each deliverable.

• Own month-end cutoffs and period discipline: ensure expenses are recorded in the correct period using accruals/deferrals and service-period logic.

• Review and approve our external accounting firm's month-end work product: proposed journal entries, reconciliations, and draft financials—ensuring accuracy, completeness, and support.

Build and maintain the accounting backbone

• Own core balance sheet reconciliations (cash, AP, accrued expenses, prepaids, and other key accounts); maintain a clear aging and resolution loop for reconciling items; and be able to explain each reconciliation.

• Build and maintain schedules that make close repeatable (prepaids, accrual schedules/rollforwards, committed spend/credits tracking where relevant).

• Implement standards for support and documentation: rec formats, JE support requirements, and audit trail hygiene.

• Partner with Finance Ops to improve close readiness inputs: documentation completeness, coding standards, and exception reduction.

Own accrual methodology for usage-based AI + cloud vendors

• Build repeatable accrual methods for key usage vendors with portal-based sources of truth (OpenAI/Anthropic/Gemini LLM providers, AI Search API providers, AWS/Azure/GCP, Snowflake/Databricks/Fivetran).

• Create vendor-specific accrual fact sheets documenting billing model, data source, cutoff rules, calculation method, JE templates, and true-up process.

• Run (or oversee) monthly usage-based accrual calculations and true-ups; investigate material variances and refine methods over time.

• Partner with Engineering/Data owners to validate usage drivers, identify anomalies, and ensure accrual inputs are timely and accurate.

Build scalable accounting policies + controls

• Establish lightweight accounting policy memos for recurring areas (prepaids/deferrals, accrual thresholds, COGS vs R&D classification, vendor commitments/credits).

• Support the rollout of by-class reporting in QBO: define class rules, ensure consistency, and partner with Finance Ops on compliance and coding guardrails.

• Strengthen controls and segregation of duties in partnership with Finance Ops and the agency: approvals evidence, documentation standards, and clean audit trails.

Manage and partner with our external accounting firm

• Serve as the internal accounting point of contact: clarifying how to code/submit spend, resolving questions, and ensuring clean handoffs.

• Maintain a high-quality working cadence with the accounting firm: clear deliverable expectations, feedback loops, and continuous improvement.

In your first few days: You’ve ramped on our accounting stack (QBO + Ramp + vendor portals), current close process, and major spend drivers. You’ve established a tight working cadence with the external accounting firm and aligned on a clear close calendar and review gates.

Within a few weeks: Close execution is more predictable and accountable: reconciliations are cleaner, accrual methods for top usage vendors are defined, and the monthly JE/review process has clear standards. You’re reducing close chasing loops via better cutoffs and better input expectations.

Within a few months: Rox has a reliable internal close captain. Usage-based vendor accruals are repeatable, true-ups are tight, and financials are consistently accurate and supported. The external firm is operating as a production partner/backstop—not a black box. Close speed and quality improve, and the accounting foundation is audit-ready.

Must-haves

• 7+ years of progressive accounting experience (Senior Accountant / Accounting Manager / Controller at a smaller company), ideally in high-growth software startups.

• This role requires a software/SaaS accounting background—comfortable with subscription revenue mechanics (deferred revenue and revenue schedules), as well as accrual/deferral discipline for operating expenses.

• Proven ability to build lightweight controls and documentation (rec templates, JE support standards, policy memos) that are audit/diligence-ready without overbuilding.

• Demonstrated experience being the primary owner of month-end close outcomes (close calendar, rec sign-off, accrual/deferral judgment, and review gates), not just executing assigned tasks.

• Accounting firm management: experience managing an external accounting firm/shared-services model and holding it to standards (JE pack quality, rec format, SLAs, escalation).

• Fluency in usage-based vendor accounting and service-period cost recognition; comfort using portal exports and cost reports as source-of-truth inputs.

• Strong working knowledge of core accounting concepts (accrual accounting, reconciliations, prepaids, expense classification) and ability to produce audit-ready support.

• Systems comfort: experience in QuickBooks Online and spend tools like Ramp (or similar). Strong Excel/Google Sheets skills.

• High ownership and strong cross-functional communication: you can drive decisions from busy stakeholders and hold a clean line on standards without creating friction.

Nice-to-haves

• Experience in AI / data infrastructure companies and familiarity with common vendor patterns (OpenAI/LLM providers, AWS/Azure/GCP, Snowflake/Databricks, Fivetran).

• Experience implementing by-class reporting in QBO (or equivalent dimensional accounting).

• Basic SQL/BI familiarity to validate spend drivers or usage datasets.

• Exposure to audit readiness, diligence support, or early-stage controls programs.

As Rox scales, we need an internal accounting owner who can lead close, enforce accounting quality, and build the repeatable accrual and reconciliation discipline that makes finance fast and trustworthy. This role reduces dependence on an external firm, improves close speed and accuracy, and builds the accounting foundation we’ll scale with over time.
