Assistant Controller / JIB Accountant

INDUSTRY: Upstream Oil & Gas

LOCATION: Midland, TX (In-Office)

EMPLOYMENT TYPE: Full-Time

CONTEXT: Our client, a small and growing upstream E&P operator, is seeking an Assistant Controller / JIB Accountant to join their team. This is a hands-on role for an accounting professional who can operate independently, take ownership of day-to-day accounting functions, and support the Controller in building a strong, reliable accounting operation.

This position will play a key role across Accounts Payable, JIB, and month-end close, with visibility into the full accounting cycle. Direct JIB experience is preferred but not required—strong upstream AP experience with the ability to learn and grow into JIB responsibilities will be considered.

The ideal candidate is dependable, detail-oriented, and comfortable rolling up their sleeves in a lean environment.

RESPONSIBILITIES:

• Own and manage full-cycle Accounts Payable for upstream operations (high-volume processing, accuracy, and timeliness).
• Review, code, and enter invoices tied to LOE, CAPEX, and field operations.
• Code costs to appropriate properties, wells, and AFEs.
• Support and/or lead Joint Interest Billing (JIB) processes, including partner billings.
• Assist with revenue distribution and partner-related accounting as needed.
• Reconcile vendor statements and resolve discrepancies in a timely manner.
• Collaborate cross-functionally with Operations, Land, and Engineering to ensure proper cost allocation.
• Support month-end close, including accruals, reconciliations, and reporting.
• Maintain organized, audit-ready financial records.
• Identify and implement process improvements to increase efficiency and accuracy.
• Serve as a key support to the Controller on ad hoc projects and accounting initiatives.

QUALIFICATIONS:

• 3+ years of accounting experience, preferably within upstream oil & gas.
• Strong background in Accounts Payable and cost coding (LOE, AFE, well-level tracking).
• Exposure to or willingness to learn JIB accounting.
• Solid understanding of month-end close processes.
• High attention to detail with strong organizational skills.
• Proven track record of tenure, reliability, and accountability.
• Self-starter who can work independently in a small team environment.
• Proficient in Excel and accounting systems (Enertia, OGSYS, WolfePak, SAP, Oracle, QuickBooks, or similar).
