Accounting Manager

Accounting Manager

Thayer Infrastructure Services is a private equity–backed, high-growth provider of power, fiber, wireless, and engineering infrastructure services. As we continue to scale — organically and through acquisition — we are building out a best-in-class finance and accounting function to support the business. This is an exciting opportunity to join a growing team and play a critical role in the company's financial infrastructure during a period of significant transformation.

Position Summary

The Accounting Manager will be a key member of the accounting team, reporting directly to the Group Controller. This role owns the monthly close process, general ledger integrity, and technical accounting areas including fixed assets, leases, and intercompany/consolidations, while also playing a lead role in the year-end audit and partnering closely with tax, FP&A, and the broader accounting organization (AP, Billing/AR). This is a hands-on role well suited for a controllership-minded professional who thrives in a fast-paced, PE-backed environment with evolving processes and high expectations for accuracy and scalability.

Key Responsibilities

Month-End Close & General Ledger

• Own and manage the monthly, quarterly, and annual close process in NetSuite, ensuring accurate and timely close in accordance with a defined close calendar
• Prepare and review journal entries, accruals, and account reconciliations
• Maintain the integrity of the general ledger, including chart of accounts governance
• Identify and drive process improvements and close-cycle efficiencies as the company scales

Consolidations & Intercompany

• Manage the consolidation process across multiple entities/subsidiaries within NetSuite
• Oversee intercompany transactions, eliminations, and reconciliations
• Support integration of newly acquired entities into the accounting close and reporting process, including chart of accounts mapping and NetSuite onboarding

Technical Accounting

• Manage fixed asset accounting, including capitalization, depreciation, and disposals — relevant given the capital-intensive nature of infrastructure project work
• Oversee lease accounting under ASC 842, including lease schedules and related disclosures
• Research and document technical accounting positions on non-routine or complex transactions, including project-based revenue recognition considerations common in infrastructure/construction-services businesses

Financial Reporting & Analysis

• Prepare and analyze monthly P&L and Balance Sheet fluctuations; provide variance commentary to management
• Partner with FP&A to ensure alignment between actuals, budget, and forecast
• Support preparation of internal management reporting packages and board/investor reporting materials

Audit & Compliance

• Serve as a key point of contact for the year-end financial statement audit, including preparation of audit schedules (PBC list) and liaising with external auditors
• Partner with tax advisors/tax team on income tax provision, compliance filings, and related deliverables
• Support the design, documentation, and monitoring of internal controls (SOX readiness a plus, depending on PE sponsor requirements)

Cross-Functional Partnership

• Collaborate closely with AP and Billing/AR teams to ensure clean hand-offs into the GL and accurate cutoffs at close
• Partner with the procurement/card program team on Ramp reconciliation, coding, and month-end tie-out of corporate card and procurement activity
• Act as a liaison between the accounting team and FP&A to ensure consistent, reliable financial data
• Support ad hoc projects, including system implementations, process re-design, and M&A integration

Team & Process Leadership

• Potential to mentor/manage junior accounting staff as the team grows
• Contribute to building scalable processes, controls, and documentation appropriate for a growing PE-backed platform
• Support NetSuite and Ramp optimization, automation, and reporting initiatives

Qualifications

Required

• Bachelor's degree in Accounting, Finance, or related field
• CPA strongly preferred (active license or CPA-eligible)
• 10+ years of progressive accounting/controllership experience; prior public accounting (audit) experience a strong plus
• Deep working knowledge of US GAAP, including consolidations, intercompany accounting, fixed assets, and lease accounting (ASC 842)
• Proven experience managing or heavily contributing to the month-end close process
• Experience preparing for and managing external financial statement audits
• Hands-on experience with NetSuite required; experience with Ramp or similar spend management platforms strongly preferred

Strongly Preferred

• Prior experience in a private equity–backed company or portfolio company environment
• Experience in infrastructure services, construction, engineering, telecom, or a similar project-based industry
• Experience with multi-entity consolidations and M&A/acquisition integration accounting
• Exposure to income tax compliance and coordination with external tax advisors
• Experience operating in a high-growth or transformational environment (new systems, evolving processes, scaling controls)
• Familiarity with SOX / internal controls frameworks

Skills & Attributes

• Strong technical accounting acumen paired with a pragmatic, hands-on approach
• Excellent communication skills; able to explain accounting concepts to non-accounting stakeholders
• High attention to detail balanced with the ability to manage competing deadlines
• Comfortable operating with limited process documentation and building structure from the ground up
• Collaborative, team-oriented mindset with the ability to work cross-functionally across AP, Billing/AR, and FP&A
• Self-starter who takes ownership and drives issues to resolution

What We Offer

• Competitive base salary
• Comprehensive health, dental, and vision benefits
• 401(k) with company match
