Role Overview Overwatch is seeking a Senior Account Manager , Accounting to join our growing finance organization, reporting to the VP of Accounting. This is a hands-on, generalist role suited to a builder who thrives in a small, fast-moving team — someone equally comfortable rolling up their sleeves during close and leading/mentoring staff.

We are specifically looking for candidates with public accounting experience (Big 4, national, or regional firm) who bring technical rigor, audit-readiness, and a strong controls mindset to a growing private company environment. Key Responsibilities: Own the monthly and annual close process, including preparation and review of journal entries, account reconciliations, and consolidated financial statements across multiple entities and business units. Oversee accounts payable and accounts receivable operations, including vendor payments, customer invoicing and collections, and cash application, ensuring accuracy and timeliness across entities. Manage and mentor a team of staff accountants, reviewing their work and developing their technical skills. Partner with the VP of Accounting on technical accounting matters, including revenue recognition construction, staffing, and services contracts. Coordinate with outside tax preparers and advisors on income tax, sales/use tax, and multi-state filings; ensure timely, accurate compliance across entities. Lead intercompany accounting and eliminations across Overwatch's business units (including international), ensuring clean, accurate consolidations. Serve as a key point of contact for the annual financial statement audit and any lender or bank-required reporting; prepare audit schedules and support requests. Design, document, and strengthen internal controls and accounting policies as Overwatch scales, identifying gaps and driving process improvement. Own or support accounting system administration and process automation (ERP, close checklists, reporting tools), improving efficiency as transaction volume grows. Support budgeting, forecasting, and ad hoc financial analysis for leadership as needed. Qualifications: Required Bachelor's degree in Accounting, Finance, or related field. CPA license (active or eligible) required. 6–8+ years of progressive accounting experience Strong technical GAAP knowledge and demonstrated experience managing a full-cycle monthly close. Experience managing or mentoring staff. Comfortable operating in a lean, fast-paced environment and building process rather than just following it. Preferred Public accounting experience at a Big 4, national, or regional firm (audit or assurance background strongly preferred). Experience with multi-entity consolidations and intercompany accounting. Experience with construction, staffing/PEO, or professional services accounting (percentage-of-completion, job costing, or contract revenue recognition). Experience with NetSuite or similar ERP systems. Big plus if you’re a quick learner and used to being the “go-to” expert! Benefits: Overwatch Construction offers a competitive salary and benefits package, including health insurance, dental insurance, vision insurance, life insurance, 401(k) retirement plan, paid time off, and relocation assistance available.
