Who You Are

We’re seeking a Senior Manager, Corporate Accounting to lead U.S. accounting execution for Justworks across our PEO and ASO business. This is a critical leadership role responsible for overseeing high-volume operational accounting areas — including AP, T&E, payroll, benefits, revenue, and cash — and for delivering a month-end close process that is timely, auditable, and continuously improving.

You will play a hands-on leadership role focused on elevating the precision, discipline, and automation of our accounting operations. This includes driving close excellence, upgrading reconciliation processes, and ensuring readiness for an SEC-compliant control environment. You bring a track record of scaling accounting operations with the help of technology, and you know what “great” looks like when it comes to documentation, controls, and sustainable close timelines.

This role is ideal for someone who has managed month-end close in a high-growth or regulated company and is ready to build structure, eliminate inefficiencies, and raise the bar across people, process, and systems.

Your Success Profile

What You Will Work On

Close Execution & Reconciliation Excellence

• Lead the U.S. month-end close process across AP, payroll, benefits, revenue, and cash — ensuring deadlines are met and outputs are accurate, complete, and audit-ready.

• Upgrade reconciliation standards to “best-in-class” — ensuring account ownership, documentation, and validation processes meet SEC readiness expectations and can scale with complexity.

• Implement a tiered risk-based approach to reconciliations — identifying material accounts, timing risks, and appropriate levels of review.

• Partner with the Global Controller to define and measure close metrics (e.g., D+ timeline goals, recon aging, manual JE ratio) and ensure continuous improvement against them.

Automation, Systems, and Technology Integration

• Identify opportunities to streamline recurring close activities using close management tools, workflow automation, and AI/ML-based reconciliation tools (e.g., FloQast AutoRec, NetSuite ARM).

• Collaborate with Engineering, Product, and Operations to improve upstream data capture and ensure automation readiness in source systems (e.g., payroll data feeds, billing).

• Working closely with the Financial Systems team, reduce manual entries and reconciliation bottlenecks through scripting, validation logic, and systems-integrated workflows.

Technical Oversight & Controls

• Own the accurate accounting of recurring, high-volume transactions — including payroll, fringe benefits, customer billing, pass-through costs, and employee reimbursements.

• Document transaction-level accounting treatments and build operational guidance for consistent application across teams.

• Work with Internal Audit and Finance leadership to maintain internal control hygiene (e.g., segregation of duties, review steps, audit trails), and help prepare for eventual SOX compliance.

AP, Payroll, Benefits & Revenue Ownership

• Oversee the execution of AP, T&E, and cash-related processes, ensuring completeness, timely payment processing, and alignment with monthly cutoffs.

• Review and improve accounting handoffs from Billing and Risk & Insurance teams — including revenue JE accuracy, benefits accruals, and carrier payables.

• Maintain alignment between revenue and cost passthroughs, ensuring invoices and GL activity reconcile appropriately to customer activity and vendor settlements.

Team Enablement & Cross-Functional Partnership

• Provide structure and support to team contributors through planning, templates, issue-tracking, and review checklists; foster a mindset of ownership, precision, and pride in the quality of deliverables.

• Support team development by providing regular feedback, identifying growth opportunities, and helping team members deepen their technical skills and process ownership across accounting areas.

• Invest in documentation and training to ensure continuity, coverage, and resiliency across critical workflows; build clear expectations and knowledge transfer frameworks to support cross-training and onboarding.

• Collaborate with cross-functional teams across Justworks — including Payroll Ops, Billing, Risk & Insurance, and Treasury — to proactively manage timing, cutoffs, and GL impacts for major activity flows.

How You Will Do Your Work

As a Senior Manager, Corporate Accounting, you are expected to lead by example, model precision and accountability, and bring a “continuous improvement” mindset to every process you touch. Key competencies include:

• Close and reconciliation discipline – establishes rigorous structure for timelines, ownership, and quality reviews; drives repeatable close excellence across multiple teams and stakeholders.

• Process and systems fluency – deeply understands how accounting workflows interact with systems and tools; continuously seeks automation, simplification, and audit traceability.

• Ethical practice – ensures that accounting judgments and documentation hold up to scrutiny; champions consistency, integrity, and transparency across the function.

• Communication and cross-functional clarity – provides direct, organized guidance to upstream and downstream teams; drives alignment and accountability around timing and expectations.

• Scalability mindset – thinks two steps ahead; builds systems and processes that support growth, enable audit readiness, and remove key person dependencies.

In addition, all Justworkers focus on aligning their behaviors to our core values known as COGIS. It stands for:

• Integrity - Simply put, do what you say and say what you'll do. You’re honest and forthright, have a strong moral compass, and strive to match your words with your actions while leading by example. 

• Simplicity - Be like Einstein: “Everything should be made as simple as possible, but no simpler.”

Qualifications

• 10+ years of progressive accounting experience, with 3+ years in a month-end close leadership role.

• CPA required; Big 4 or public accounting experience strongly preferred.

• Demonstrated ability to lead and improve accounting operations in a high-growth, multi-product environment.
