Job description

Happiest Baby is a mission-driven company dedicated to helping parents raise healthy, happy children. Founded by pediatrician and best-selling author Dr. Harvey Karp and entrepreneur Nina Montée Karp, we make SNOO, the world’s first smart sleeper, which is used in hospitals, offered as an employee benefit by leading companies, and has helped hundreds of thousands of families get more sleep.

About the Role

The Senior Accountant is a hands-on accountant who reports to the Senior Manager, Accounting, supervises the accounts payable and accounts receivable clerk, and owns three core responsibilities of equal weight: (1) general ledger (GL) accounting and the monthly close, including rental revenue; (2) accounts payable (AP), accounts receivable (AR), and purchasing; and (3) optimizing and automating both areas with artificial intelligence (AI), including Claude Cowork and AI agents. The role supports financial planning and analysis (FP&A) as needed and works with Operations, Customer Care, Business Development, and leadership.

We are a lean team in a fast-moving business. Processes that were sufficient yesterday may need to be rebuilt tomorrow. We want someone who pairs accounting rigor and strong Excel modeling with practical AI fluency, and who will use it to automate recurring work. Human review is required on every work product, whether prepared by hand or with AI, and the preparer remains accountable for its accuracy.

Core Responsibilities (Required)

General Ledger Accounting and Close

• Own the monthly close: accruals, prepaids, journal entries, reconciliations, flux analysis, close checklists, and monthly financial statements; resolve reconciling items before close.
• Inventory and cost accounting: landed cost, inventory roll-forwards, rental asset depreciation, excess and obsolete (E&O) reserves, and physical counts across warehouses and third-party logistics (3PL) sites.
• Debt and equity roll-forwards, analyses, and reconciliations.
• Rental revenue: own the rental revenue workbook and apply Accounting Standards Codification (ASC) 606 and ASC 842 to consumer and corporate rentals and prepaid contracts. The workbook covers:
• Order to cash: reconcile rental billings, failed payments and voids, and processor settlements and fees to cash and the GL.
• Deferred revenue roll-forward: beginning balance, billings, revenue recognized, and ending balance, monthly.
• Balance sheet reconciliation: reconcile rental receivables and deferred revenue to the GL and record adjusting entries.
• Deferred revenue aging: age the balance by origination and earning period, and resolve stale or unsupported items.
• Maintain the workbook’s documentation and controls, and automate its refresh and checks.

Accounts Payable, Accounts Receivable, and Purchasing

• Supervision: assign, prioritize, review, and approve the AP and AR clerk’s work, and provide training and feedback.
• Accounts payable: administer procure-to-pay (invoice intake and coding, Bill.com approvals, weekly payment runs, payment within terms) and review invoices and expense reports for accuracy, coding, eligibility, and duplicates.
• AP aging and reconciliation: review the AP aging weekly, reconcile the AP subledger to the GL monthly, and record accruals and maintain cutoff.
• Purchasing: maintain the purchase order (PO) register and numbering, prepare and issue POs, load approved POs into the accounting system, and support bill-to-PO matching.
• Accounts receivable: invoice customers (including corporate rental customers) timely and accurately, apply payments, clear unapplied cash promptly, and resolve discrepancies.
• AR aging and reconciliation: review the AR aging weekly, reconcile AR subledgers and payment processor clearing accounts to the GL monthly, resolve customer credit balances, and recommend the allowance for doubtful accounts.
• Collections: administer collections, report on aged receivables, and work cross-functionally to manage collections and days sales outstanding (DSO).
• Daily processing: post bank activity in QuickBooks Desktop Enterprise, run the Bill.com and Expensify syncs and resolve errors, and maintain vendor and customer master data.
• Collect vendor taxpayer identification numbers and prepare Form 1099 and Form 1096 filings.

Process Optimization and Automation with AI

• Baseline recurring workflows (volumes, hours, error rates, rework) and decide deliberately which steps to automate and which stay with a person.
• Fix the process before automating it: standardize intake, simplify approvals, and use system configuration (bank rules, coding rules, recurring bills) wherever it is simpler than an agent.
• Build and maintain Claude Cowork agents for work such as PO preparation, bill-to-PO matching, cash application, collection reminders, bank posting and syncs, reconciliation preparation, the rental revenue workbook refresh, and first-draft flux commentary.
• Measure results monthly (time saved, error rates, rework, exceptions) and report them to the Senior Manager, Accounting.
• Controls: maintain segregation of duties over procure-to-pay and cash, with approval gates on PO creation, vendor master changes, and payment release; document each automation (inputs, instructions, outputs, reviewer, date) so auditors can reperform it.

Additional Responsibilities (As Needed)

• Support FP&A: forecasting, variance analyses, and Board and lender materials.
• Ad hoc analyses, including tracking external spend by vendor.
• Payroll accounting with our professional employer organization (PEO): review, post, and reconcile payroll.
• Audit schedules and support for the annual financial statement audit.
• Coordinate with tax advisors on sales and use, state and local, international indirect, and income tax filings.
• Extend process, control, and automation improvements across Finance and train colleagues.

Required AI Skills and Responsible Use

Every AI-assisted output is reviewed, validated, and approved by a person before it is relied on, posted, filed, or shared.

Proficiency and Workflow Design

• Hands-on use of Claude (including Claude Cowork) or comparable enterprise AI tools for reconciliations, flux and variance commentary, technical memos, policies, and data analysis.
• Builds reusable agents, skills, prompts, and templates; writes clear instructions with context, constraints, examples, and output format; and breaks processes into testable steps, keeping estimates, approvals, and accounting conclusions with a person.
• Connects AI tools to Excel, SharePoint, OneDrive, Confluence, Jira, and enterprise resource planning (ERP) exports with least-privilege access.
• Stays current on AI capabilities relevant to finance and accounting.

Human Review, Controls, and Security

• Signs off on every AI-assisted work product and validates it independently: ties to source documents and the GL, recalculates, runs analytical checks, and sample-tests detail.
• Recognizes AI failure modes: fabricated figures or citations, misapplied standards, stale data, silent formula errors, and overconfident conclusions.
• Never relies on AI for a final accounting judgment, estimate, or disclosure without documented support and human review.
• Treats AI-enabled processes as part of internal control over financial reporting (ICFR), with change management, version control, and evidence retention.
• Uses only approved AI tools under company AI governance policies, protects confidential and personally identifiable information (PII), and escalates accuracy or security concerns promptly.

Qualifications

Required

• Bachelor’s degree in Accounting, or a related field with a strong accounting background.
• Progressive accounting experience, including hands-on AP, AR, and purchasing, deferred revenue, and month-end close (accruals, prepaids, inventory, fixed assets, debt), preferably in consumer product, subscription, or startup settings.
• Solid knowledge of US generally accepted accounting principles (GAAP), particularly ASC 606 (revenue), ASC 842 (leases, including lessor accounting), ASC 330 (inventory), and ASC 360 (property and equipment), and of financial controls.
• Advanced Excel (Power Query, Power Pivot, lookup and dynamic-array functions) and the ability to build auditable, formula-driven models with no hardcoded numbers in calculations.
• Working knowledge of SQL, Python, or Visual Basic for Applications (VBA), enough to test and maintain AI-generated scripts.
• Experience with QuickBooks Desktop Enterprise or a similar ERP, Bill.com, and Expensify.
• Demonstrated AI proficiency as described above, with measurable results automating AP, AR, purchasing, or reconciliation workflows.
• Experience supervising, training, and reviewing AP or AR staff.
• Strong time management, attention to detail, and analytical skills, and the ability to explain technical matters to non-finance colleagues.

Preferred

• Certified Public Accountant (CPA) license, or progress toward one, and public accounting (audit) experience.
• Subscription or rental business models, and FP&A exposure, including cohort-based forecasting.
• Inventory and landed-cost accounting, physical counts, 3PL operations, and supply chains.
• Foreign subsidiaries, multi-currency, and consolidation; Amazon QuickSight or Power BI.

Qualities We Value

• Fierce curiosity, a growth mindset, and a self-motivated, solution-oriented bias for improving how work gets done.
• Confident yet humble; eager to learn and to help others develop.
• Thrives in a lean, mission-driven environment and builds trust through accuracy and follow-through.
• Competitive health, dental, and vision plans; a 401(k) plan; and a generous vacation policy.
• A friendly, dynamic office and a team making a meaningful difference in the lives of parents and babies.
