About the role

Hi, I'm Eric, Senior Controller at Customer.io, and I'm looking for a Senior Accountant contractor to cover a maternity leave from approximately May 2026 through March/April 2027. You'll spend the first few months working directly alongside our current Senior Accountant for a thorough handoff, then take the reins independently on payroll accounting, commissions, benefits reconciliations, and our monthly close process.

This is a full-time contract (40 hrs/week), fully remote. You'll be a key cross-functional partner to HR, Sales Operations, FP&A, AP, and Payroll — and a consistent presence in our CFO accounting review process each month.

What we value

• Obsessive attention to detail — you catch things before they become problems

• Comfort owning your work independently after a solid transition

• Clear, proactive communication with cross-functional partners

• The instinct to flag discrepancies and ask "why" before moving on

• Reliability during a critical coverage period — the team is counting on you

What you'll do

• Prepare and record all payroll journal entries across ADP (mid-month, month-end, off-cycle), Deel, and Velocity Global

• Reconcile all payroll-related balance sheet accounts at the employee level, including monthly flux analysis for CFO review

• Record monthly accruals for benefits, SUI rate changes, and FX adjustments on international commissions

• Prepare monthly commission entries, maintain the deferred commission waterfall schedule, and handle short- and long-term balance sheet reclassifications

• Reconcile benefits at the employee level monthly and record adjusting entries tied to vendor billing and policy changes

• Handle sales tax: reconcile payable accounts, prepare and remit monthly state-level filings

• Serve as FloQast administrator — managing reconciliations, task assignments, and close checklist oversight

• Support the monthly close process end-to-end and ensure timely delivery of all assigned items

What we're looking for

• 4+ years of progressive accounting experience with a strong focus on payroll and commission accounting

• Solid grasp of multi-state (and ideally international) payroll accounting, deferred commission capitalization, and accrual accounting

• Hands-on experience with ADP; familiarity with Deel is a plus

• FloQast experience is a strong plus

• Strong Excel skills — you're comfortable working with large, employee-level datasets

• A communicator who can work fluidly with HR, Sales Ops, FP&A, and AP without missing a beat

• Bachelor's degree in Accounting or Finance

Contract Details

• Duration: ~May 2026 – March/April 2027 (maternity leave coverage)

• Hours: Full-time, 40 hours/week

• Rate: $50–$60/hour

• Location: Remote

• Tools: ADP, Deel, Velocity Global, FloQast, Excel

Our Process

No gotchas, no trick questions — just a clear, human process designed to help both of us make an informed decision.

• 30-minute video call with a Recruiter

• 45-minute video call with Hiring Manager

All final candidates will be asked to complete a background check and employment verifications as part of our pre-employment process.
