About the Role

Panthalassa continues to expand and strengthen our internal finance and accounting capabilities as the company scales from R&D toward manufacturing and deployment. We are looking for a hands-on accounting operator to own the accuracy, reliability, and responsiveness of our day-to-day accounting workflows. 

This is a high-ownership operating role that goes beyond AP processing. You will excel if you are a practical problem solver who can build and operate processes that ensure clean data, clear processes, and accurate books at scale. 

You will be responsible for making sure vendors are onboarded correctly, invoices are entered and routed cleanly, payments move through the right process, and transactions are coded accurately in our ERP. You will work across finance, engineering, manufacturing, procurement, vendors, and external accounting partners to understand the business context behind spend and translate that context into consistent accounting treatment.

While mastery of the fundamentals of accounting is critical, we want someone who is technology-forward and excited to use AI and modern productivity tools to make accounting processes faster, cleaner, more auditable, and more scalable without sacrificing accuracy or judgment.

Key Responsibilities

• Own and support core accounting operations, including accounts payable,procure-to-pay, and month-end close workflows.
• Manage vendor onboarding, vendor records, invoice intake, bill entry, approval routing, payment preparation, and payment follow-up.
• Maintain clean, accurate financial data in NetSuite, including transaction coding, vendor records, reporting inputs, and process documentation.
• Ensure invoices, bills, expenses, and payments are coded accurately by department, project, vendor, spend category, and other relevant dimensions.
• Assist with spend tagging and reporting to improve visibility for budgeting, forecasting, and financial planning.
• Work with internal teams to understand the context behind purchases and translate that context into repeatable accounting and coding rules.
• Support timely and accurate month-end close, including reconciliations, journal entries, accruals, prepaid expenses, account analysis, and supporting schedules.
• Identify repetitive, manual, or error-prone workflows and propose practical ways to improve them using process improvement, automation, AI tools, better spreadsheet design, workflow software, or ERP configuration. 
• Support payment operations, including vendor questions, missing payments, invoice discrepancies, payment timing, and related issue resolution.
• Support audit, tax, compliance, and other finance requests as needed.
• Partner with finance and leadership, accounting leadership, and external accounting partners on technical accounting questions, controls, close tasks, and reporting needs.
• Maintain an extremely high bar for accuracy, confidentiality, responsiveness, and ownership.

Qualifications

• 5+ years of accounting, accounting operations, accounts payable, general ledger, or related finance operations experience.
• Strong accounting fundamentals and familiarity with U.S. GAAP.
• Experience with accounts payable, vendor onboarding, payment processing, invoice coding, and month-end close support.
• Ability to book journal entries and understand when to escalate more complex accounting questions.
• Technology-forward, with strong judgment for using AI, automation, and modern tools to improve accounting workflows while preserving accuracy and controls. 
• Strong communication skills with both internal stakeholders and external vendors.
• Ability to understand business context and turn it into clear, repeatable accounting treatment.
• Comfort working in spreadsheets and with financial data; you do not need to be a hardcore quant, but you should have strong number sense.
• Experience with NetSuite or another ERP system.
• Strong Excel skills.
• A hands-on, ownership-oriented mindset and willingness to do the work directly.
• Comfort building and operating processes in a fast-moving, lean environment.

Desired Qualifications

• NetSuite experience strongly preferred.
• CPA or CPA-track background.
• Bachelor’s degree in Accounting, Finance, Business, or a related field preferred.
• Experience in a startup, manufacturing, hardware, energy, infrastructure, or project-based environment.
• Experience improving or documenting accounting processes.
• Experience supporting audit, tax, compliance, or technical accounting requests.
• Experience with procure-to-pay workflows, payment systems, expense management tools, or ERP implementations.

The above qualifications are desired, not required. We encourage you to apply if you are a strong candidate with only some of the desired skills and experience listed.
