Staff Accountant

Nucleus is seeking Staff Accountant who’s excited to roll up their sleeves, own processes, and help build a best-in-class accounting foundation.

This is not a “just post the journal entries” role. You’ll be a core part of our monthly close, help improve systems and processes, and gain exposure across the business. If you enjoy working in a fast-paced environment where things evolve quickly, you’ll thrive here.

What You Will Do

  • Perform balance sheet reconciliations and keep supporting schedules clean and audit-ready

  • Handle key procedural elements of the accounts payable process, including entering invoices into the accounts payable system, obtaining proper approvals, establishing proper GL coding, and triggering disbursements

  • Onboard new vendors, request and store Form W-9s, and process Form 1099s

  • Support revenue recognition (SaaS / ASC 606 exposure is a plus)

  • Assist with customer invoicing and billing processes

  • Assist with annual GAAP financial statement audits, tax return preparation, and any other outside examinations, as needed, including preparing and sending data requests

  • Continuously look for ways to improve systems and procedures and initiate corrective actions.

Expectations of Your Experience

Required Qualifications:

  • 1–2 years of experience in public accounting or at a tech/startup environment

  • Solid understanding of U.S. GAAP

  • Experience supporting month-end close

  • Strong Excel skills (pivot tables, lookups, comfort with large datasets)

  • Self-starter who’s comfortable with some ambiguity

Preferred Qualifications:

  • Experience with corporate card & expense management platforms

  • Experience with accounting/ERP platforms

  • Experience in a SaaS or subscription-based business

  • Exposure to billing, invoicing, or accounts receivable processes

Why You Should Be Excited

  • 100% company-paid health, dental, vision, life, and short-term disability insurance options

  • Generous 401k contribution (not a match)

  • Flexible PTO + 10 company holidays

  • Fantastic company culture

  • Work on a truly unique, market- defining product

Salary Range: $55,000 - $70,000
