About the role

We’re an AI and physical sciences company building state-of-the-art models to accelerate breakthroughs across materials, energy, and beyond. We’re hiring our first in-house Controller to own the integrity and day-to-day operation of Periodic Labs’ accounting function, including accounting, financial reporting, controls, audit readiness, and compliance. This hands-on builder role involves shaping the accounting function, building systems, and potentially growing an internal team across a multi-entity organization.

Responsibilities

  • Own the monthly, quarterly, and annual close process, including the general ledger, consolidations, reconciliations, accruals, journal entries, and preparation of GAAP financial statements.
  • Manage daily accounting operations, build and maintain robust processes across procurement, vendor management, employee expenses, revenue, and capital expenditure management.
  • Develop a close and reporting cadence that gives leadership reliable visibility into the income statement, balance sheet, cash flow, working capital, and material period-over-period changes. Partner with Strategic Finance to deliver clean actuals for forecasts, runway analysis, board materials, investor reporting, and operating decisions.
  • Own accounting policies and technical conclusions for areas such as leases, fixed assets and leasehold improvements, prepaid services, equity and stock-based compensation, R&D arrangements, capitalization, foreign currency, and emerging commercial agreements.
  • Oversee accounting for Periodic Labs’ U.S. and international entities, including intercompany activity, statutory reporting, payroll-related obligations, and coordination of U.K., Canadian, and U.S. compliance requirements.
  • Continue enhancing NetSuite functionality and its integration with supporting systems to ensure scalable, flexible reporting at the appropriate level of detail as the company grows.
  • Work cross-functionally with Legal, People, Operations, Lab Operations, and technical teams to evaluate the accounting and control implications of new contracts, programs, facilities, and business models.
  • Be the key point of contact with external advisors (e.g. auditors, tax advisors).

Qualifications

  • 10+ years of progressive accounting experience, including meaningful ownership of an end-to-end accounting function. Experience leading or playing a central role in building up a company’s accounting team from ground up.
  • An active CPA license and strong command of U.S. GAAP.
  • A track record leading and managing an accounting team with clear standards and accountability.
  • Deep, hands-on experience with monthly close, financial-statement preparation, balance sheet reconciliations, audit support, and internal controls.
  • Strong NetSuite experience and familiarity with modern finance tools such as Ramp and Rippling.
  • Experience in a rapidly growing, venture-backed company where processes, systems, and responsibilities are still being built.
  • The ability to move comfortably between technical accounting questions and detailed operational work. You are willing to investigate a reconciliation, review an invoice, or write an accounting memo yourself.
  • Clear written and verbal communication skills, including the ability to explain accounting issues to people without accounting backgrounds.
  • High integrity, strong attention to detail, and operate with agency.
