Assistant Controller

About the role

MGT is the first AI‑driven neo‑insurer focused on evolving commercial P&C insurance for brokers and small business owners. By combining industry‑veteran expertise with state‑of‑the‑art technology, MGT is ushering in the next evolution of commercial insurance through modern technology, better processes, and a rock‑star team. MGT Insurance is seeking an Assistant Controller to lead our accounting operations. As MGT continues to scale we are hiring an Assistant Controller who will take ownership of the monthly close, accounting controls, financial controls and external audit. In this role, you will oversee the close and reporting process across five consolidated entities under both GAAP and statutory accounting requirements. You will lead and develop the accounting team, strengthen our control environment, and serve as the primary relationship owner for our external auditors. You will do so on a modern technology platform built substantially in house. MGT is an AI‑first company, and that commitment extends to the accounting function as well as to the product. Automated pipelines and AI agents perform a growing share of reconciliation work. Professional judgment remains the control that gates the close.

Responsibilities

• Implement close‑management software: lead the implementation on top of NetSuite, defining the close checklist, reconciliation templates, review hierarchy, and sign‑off trail to move the close from institutional knowledge into a documented, auditable system.
• Establish balance sheet integrity across all five entities: define and enforce a company‑wide account reconciliation standard covering ownership, frequency, supporting documentation, and review; own subledger‑to‑general‑ledger tie‑outs for premium receivable, commissions payable, and cash; drive aged reconciling items to resolution.
• Establish audit and examination readiness at scale: document accounting policy, capture evidence at the source, create clear statutory‑to‑GAAP bridges, and build a PBC process that scales with the business.
• Own the close: lead the monthly, quarterly, and annual close across all five entities; serve as the primary reviewer, approving journal entries, reconciliations, roll‑forwards, and flux analyses prepared by the team; set the close calendar and hold the organization to it.
• Manage GAAP and statutory reporting: deliver consolidated GAAP financial statements and statutory financial statements reviewed by regulators and rating agencies; own the annual and quarterly NAIC statements, state insurance department filings, and premium tax filings across the licensed footprint; maintain a clear, well‑documented statutory‑to‑GAAP bridge.
• Manage the audit: serve as the primary liaison to financial auditor and external auditors, coordinating the PBC list, managing timelines, and resolving technical matters directly; support preparation of responses to financial examinations and regulatory inquiries.
• Author accounting policy: prepare technical accounting memoranda for non‑standard transactions, including new program structures, reinsurance arrangements, product launches, and entity changes; establish and maintain the accounting policies, procedures, and internal controls required to support the company's growth.
• Lead the team: lead and develop the accounting team; set priorities, review work product, invest in the professional growth of staff, and foster a culture of accountability, accuracy, and continuous improvement.
• Build and automate the systems: own the accounting architecture in NetSuite and partner with Engineering, Data Science, and FP&A on data pipelines that move policy, claims, and billing information into the general ledger; work with Ramp, Stripe, Aleph, proprietary policy administration, billing, and AI‑enabled data services (including Claude); identify recurring manual work and treat automation as the default solution.
• Partner beyond Finance: work directly with Operations, Product, Engineering, Data, Actuarial, and FP&A; a meaningful portion of this role involves data and systems work in addition to traditional accounting responsibilities.

Requirements

• 8+ years of accounting experience in insurance, financial services, or public accounting serving those clients.
• 3+ years directly managing accounting professionals, with a demonstrated record of developing staff and elevating the quality of their work.
• Demonstrated ownership of a multi‑entity month‑end close and consolidation, including review of work prepared by others.
• Experience serving as a primary counterparty to external auditors.
• Strong command of US GAAP and statutory accounting; working knowledge of P&C insurance accounting.
• Hands‑on experience with a modern ERP; NetSuite strongly preferred.
• Demonstrated ability to apply AI tools and emerging technologies to automate workflows, improve productivity, and strengthen internal controls, with specific examples of recurring work you have eliminated.
• Advanced Excel and strong analytical capability.
• Comfort with SQL, or the willingness to develop it.
• Sound judgment and clear communication, with the ability to build process in a developing control environment and to escalate issues appropriately.

Qualifications

• CPA license, or active progress toward one.
• P&C carrier, MGA/MGU, reinsurance, or program business experience, including statutory/NAIC reporting, premium taxes, bordereaux, ceding commissions, trust accounting, producer commissions, or TPA claims flows.
• Experience implementing a close‑management, reconciliation, or reporting platform such as FloQast, BlackLine, Numeric, or Workiva.
• Experience at a venture‑backed company scaling toward a Series C or beyond.
• Big 4 or national firm foundation.
