Accounting Manager

Our Mission

Reflection is a research lab making intelligence open and accessible for everyone to use, customize, and build on. We build open models that let anyone control their intelligence and help shape the future of AI. Our mission: make intelligence open and accessible to all.

About the Role

You'll be the first dedicated accounting hire at Reflection. This is a foundational role: you'll own accounting operations and compliance across our jurisdictions.

What You'll Own

• Monthly close & bookkeeping. Up-level and partially in-house our monthly close process, currently managed by an external bookkeeping firm. Coordinate across entities to ensure accurate, timely financials.

• Accounts payable. Own the full AP cycle — vendor onboarding, invoice processing, payment runs, and reconciliation.

• Payroll. Manage payroll across the US and UK (via providers), including the complexity around insurance, tax withholdings, and benefits deductions. Ensure accuracy and compliance.

• Employee expenses. Own expense approval workflows, set and enforce expense policies, and manage the reimbursement process.

• Tax & compliance. Ensure all tax filings and associated compliance obligations are completed on time and accurately across jurisdictions. Manage relationships with external tax advisors.

• Audit readiness. Coordinate prospective audits across US and UK entities — prepare documentation, liaise with auditors, and remediate findings.

• Systems. Lead evaluation and implementation of systems changes as needed (e.g., NetSuite migration) to support revenue recognition, international entity consolidation, and scale.

• Treasury. Provide treasury reporting and support liquidity management across entities and currencies.

What We're Looking For

• Experience as an early accounting hire at a high-growth, venture-backed company

• 4-8 years of progressive accounting experience

• Multi-entity and international accounting experience (intercompany, multi-currency, statutory reporting)

• Track record of building processes from scratch in an unstructured environment

• Experience implementing new tools, including ERP/system of record migrations

• Comfortable being deeply hands-on while also thinking strategically about what the function needs next

• CPA or equivalent qualification preferred
