Job description

The Series B data room is open, the PCAOB auditors just sent over their PBC list, and nobody is scrambling, because the books are clean and the close runs like clockwork. That’s the Controller this company needs, and it could be you.

About the Company:

Our client develops data center and inference center capacity, including brownfield retrofit projects, alongside major financial and industry partners. They’re a lean team of about six, backed by an experienced leadership team and board, and they’ve completed their Series A. Next up: a Series B and a potential public listing.

The Opportunity:

The CFO needs a hands-on Controller to take full ownership of accounting so they can stay focused on strategic finance, modeling, and transactions. You’ll clean up and own the books, run a timely close, build the data room, support PCAOB audits, and prepare financial information for banks, lenders, and insurers. The role starts at 20 hours a week through the end of the year and moves to full-time after that, with direct influence on how the company is financed, audited, and prepared for the public markets.

Why This Role Stands Out:

• Build it your way. Set the policies, controls, and systems the company will rely on as it scales.
• Sit at the financing table. Your data room, diligence responses, and lender and insurer reporting directly support the Series B and project financing.
• Get public company ready. Lead the work toward clean PCAOB audits, no material weaknesses, and a potential listing.
• Work with real leadership. Partner closely with the CFO, the board, and outside investors and lenders.
• Grow a team. Own the function today and build an accounting team as the company grows.
• Leave manual work behind. Use AI, LLMs, and modern accounting software to speed up the close and reporting.

What You’ll Own:

• Cleaning up historical accounting and moving work from outsourced providers to strong internal ownership
• The full month-end and year-end close, delivering timely, accurate GAAP financials to the CFO, leadership, board, and investors
• PCAOB audit support and the audit relationship, including planning, PBC lists, and timelines, plus the transition to a new audit firm after the current engagement
• Internal controls and accounting policies built for public company reporting
• The data room and diligence responses for investors, banks, and lenders
• Financial reporting for banks, lenders, and insurers supporting project financing and insurance needs
• Support for the CFO on Series B fundraising and financing activities
• Equity and capital accounting, including equity issuances and stock-based compensation
• Oversight of AP, AR, payroll accounting, and cash management
• Partnering with outside advisors on tax filings and compliance
• Automating the close, reporting, and analysis with AI tools, LLMs, and modern software

What You Bring:

• Active CPA license
• 8+ years of progressive accounting experience
• 3+ years in Big 4 or comparable large-firm public accounting, ideally audit
• 2+ years as a Controller, Assistant Controller, or SEC reporting lead, owning the close and the audit relationship from the company side
• Hands‑on experience with PCAOB audits and public company reporting requirements
• A track record of timely closes and audits with no material weaknesses
• Real enthusiasm for AI and automation in day‑to‑day accounting work
• Bachelor’s degree in Accounting or a related field

Bonus Points If You Have:

• Helped a company go public through an IPO or another listing route
• Served as Controller or Assistant Controller at a venture‑backed or high‑growth company
• Prepared financials for lenders, banks, and insurers, especially in project finance
• Handled equity financing and stock‑based compensation accounting
• Experience in data centers, energy, infrastructure, or other capital‑intensive industries

You’ll Thrive Here If You:

Bring low ego and high ownership, welcome direct feedback, and own your mistakes. You’re comfortable with experienced executives and board members, steady in ambiguity, and energized by a fast‑paced, transparent environment that embraces modern tools.

The Details:

• Schedule: Part‑time (20 hours/week) through the end of 2026, moving to full‑time in January 2027
• Reports to: CFO
• Location: Remote/hybrid, Dallas, TX
• Compensation: $150,000 to $170,000 annualized
