Job Description

Senior Accounting Manager / Hands-On Controller

Position Overview

We are seeking an energetic, detail-oriented, and self-motivated Senior Accounting Manager / Controller to own our end-to-end accounting operations and financial management. This role is a hybrid of tactical execution and strategic oversight: you will handle day-to-day general ledger bookkeeping, AP/AR, and payroll, while also managing ASC 606 revenue recognition, financial reporting, external audits, and tax strategy.

The ideal candidate thrives in a fast-paced growth environment, can seamlessly switch from daily operational accounting to executive-level reporting, and has proven experience establishing accounting systems for venture-backed startup companies.

Key Responsibilities

  • Financial Strategy, Controls & Compliance
    • Accounting & GAAP Oversight: Enforce technical GAAP compliance, establish internal controls, design finance policies, and set up scalable accounting processes.
    • ASC 606 Implementation: Oversee revenue recognition policy design and execution, including contract-level revenue modeling.
    • Audit & Tax Management: Lead external annual audits with CPA firms, manage documentation readiness, and oversee annual tax strategy and compliance.
    • Compliance & Governance: Manage lender, investor, and federal grant compliance. Evaluate corporate insurance policies and ensure adherence to federal, state, and local regulations.
    • Equity & Cap Table Support: Maintain equity accounting, including convertible notes and SAFEs.
  • Financial Analysis & Strategic Reporting
    • Financial Reporting: Prepare and present monthly, quarterly, and annual financial statements, management dashboards, and board/investor reporting packages.
    • Cost Control & KPIs: Establish key performance indicators (KPIs), analyze performance trends, and perform cost control analysis on payroll, operating expenses, and COGS.
    • Specialized Accounting: Oversee inventory/WIP reporting, job and project cost accounting, and COGS analysis.
  • Daily Accounting & Full-Cycle Operations
    • General Ledger & Bookkeeping: Manage full-cycle bookkeeping, maintain and balance subsidiary accounts, post transactions, and prepare accruals on a monthly, quarterly, and yearly basis.
    • AP / AR / Payroll: Execute full-cycle Accounts Payable (including check run control), Accounts Receivable, and process/approve payroll on schedule.
    • Reconciliations & Assets: Perform bank, credit card, and subsidiary account reconciliations; set up and maintain fixed asset schedules.
    • Systems & Software: Implement, maintain, and leverage cloud-based finance and ERP software to improve team efficiency.
    • Vendor & Partner Management: Coordinate with outside attorneys, accountants, lenders, tax preparers, and benefits administrators.


Qualifications & Requirements

  • Education: Bachelor’s degree in Accounting, Finance, or a related business field.
  • Experience: 7–10+ years of progressive corporate finance/accounting experience, with strong preference given to experience in public audit, a Controller role, or early-stage/venture-backed startups.
  • Technical Skills: Deep expertise in GAAP, ASC 606, inventory/WIP accounting, job costing, and equity accounting (SAFEs, convertible notes). Proficiency with cloud accounting tools (QuickBooks Online, BILL, Gusto, Ramp, Expensify), advanced Excel, and modern collaboration tools (Slack, Google Workspace).
  • Soft Skills & Attributes: Meticulous attention to detail with exceptional time management and problem-solving skills in high-growth environments. Strong communication skills with the ability to translate complex financial data into actionable insights for stakeholders. Ability to work independently and remotely with minimal supervision.
  • Preferred / Plus Factors
    • Industry Experience: Experience in high-tech, battery, or manufacturing industries.
    • Grant Compliance: Experience with Federal Grant Compliance.
