What the job involves
- The Senior Accounting Manager will oversee the accounting operations of a newly public company in its first full year of SOX 404(b) compliance, including managing the month-end close process, owning the integrity of the general ledger, and serving as a named control owner within our SOX framework
- Reporting to the Director of Accounting, this role leads a team of GL and AP accountants, acts as a primary day-to-day contact for our external auditors, and is accountable for the monthly management reporting package including flux analysis and cost-per-test economics
- Month-End Close: Manage the month-end and quarter-end close on a dependency-gated calendar in FloQast, including the journal entry control log, reconciliation sign-offs, and close checklist completion driving continuous compression of the close timeline while raising quality and audit-readiness
- General Ledger Oversight: Own the accuracy and integrity of the general ledger in NetSuite, including review of recurring and non-standard journal entries, balance sheet reconciliations across the full account population, and root-cause resolution of posting and configuration issues
- Internal Controls (SOX 404(b)): Serve as a named owner and reviewer for financial reporting, GL, and close-cycle controls. Maintain control narratives and supporting documentation, ensure IPE (information produced by the entity) meets completeness and accuracy standards, and remediate deficiencies with urgency.

- Financial Reporting & Flux Analysis: Own the monthly management reporting package: month-over-month flux analysis by functional area (COGS, R&D, S&M, G&A), cost-per-test analytics for the prenatal and oncology products, and a management summary suitable for the CFO and leadership team
- Team Leadership: Lead, mentor, and develop a team of GL and AP accountants spanning general ledger, fixed assets, accounts payable, and payroll, setting clear expectations, building review discipline into every deliverable, and growing the team’s technical depth as the company scales
- Technical Accounting: Operationalize technical accounting conclusions in areas including ASC 842 lease accounting including embedded lease assessment, ASC 730 R&D cost treatment, and self-funded health plan IBNR reserves
- Process Improvement: Drive improvements to the close and accounting processes bringing both increased speed & efficiency and demonstrated operational compliance
- Procure-to-Pay Controls: Provide senior oversight of the vendor master and disbursement control environment, partnering with the Supply Chain team to provide support and governance of procurement across the AP and payment cycle
Our take
BillionToOne is a precision diagnostics company. Its proprietary molecular counting platform (Quantitative Counting Templates) accurately counts DNA molecules at the single-count level, which has the ability to significantly improve disease detection. While initially focused on prenatal screening and oncological liquid biopsies, the company’s QTC technology is highly scalable and has the ability to make vast improvements to a range of disease detection verticals.
The company’s funding efforts - most notably a 2025 IPO - will enable it to focus on further development and commercialisation of its noninvasive prenatal screening test and oncology products. However, it will need to maintain a strategic outlook, prioritising areas with higher testing frequencies to maximise patient benefit and balance test development costs.
BillionToOne has an important role to play in improving healthcare equity. As more promising peer-reviewed research studies are conducted and providers increase confidence in the company’s tests, BillionToOne has significant growth potential.
