Want a front-row seat to the decisions that shape a growing energy company? Apex Natural Gas is looking for a sharp, curious Reservoir Engineering Aanalyst to work directly with our Executive Team, testing assumptions, validating economics, and solving our highest-priority business questions.

About Apex

Apex Natural Gas is a private equity-backed upstream natural gas company focused on disciplined growth, operational excellence, and value creation in the Haynesville Shale. We're building a high-performing, collaborative team to support our upstream operations and commercial goals.

The Role

Reporting to the CEO, you'll support strategic planning, economic analysis, and executive decision-making by pursuing high-priority questions, proving the numbers, and developing clear, actionable conclusions.

You’ll work across Reservoir Engineering, Marketing, Finance, Midstream, and Operations, with significant ownership of our economics and planning models. We're looking for a reservoir engineering foundation, strong ARIES capability, sound business judgment, and responsible use of AI-enabled tools to speed up analysis without compromising accuracy or control.

What You'll Do

• Conduct focused strategic, technical, commercial, and economic analyses at the CEO's direction
• Build, maintain, audit, and improve corporate economics, forecasting, and planning models, including hands-on work in ARIES
• Partner across Reservoir Engineering, Marketing, Finance, Midstream, and Operations to reconcile data and develop integrated answers
• Test assumptions, investigate variances, and trace results back to reliable source data
• Support development planning, production and reserves analysis, capital allocation, and scenario evaluation
• Turn complex technical and commercial information into concise recommendations and executive presentations
• Use AI-enabled tools to accelerate research, analysis, and model review while independently validating outputs
• Take on ad hoc analyses and special projects as priorities evolve

What You'll Bring

• Bachelor's degree in Petroleum Engineering or a closely related engineering or quantitative discipline
• 3 years of upstream E&P experience, including reservoir engineering responsibilities
• Hands-on proficiency with ARIES and upstream economic evaluation, plus experience with reserves, production forecasting, development planning, and well economics
• Advanced Excel and financial or economic modeling skills
• Working knowledge of how production, marketing, midstream, reserves, and finance connect
• Experience using, evaluating, or learning AI-enabled analytical tools (preferred)

What Will Make You Successful

• Intellectual curiosity and healthy skepticism: you don't accept a number without understanding its source, assumptions, and limitations
• Quick learning, openness to direction, and execution within the CEO's priorities
• Balance of analytical depth, speed, and practical business judgment
• Clear communication with technical, commercial, financial, and executive stakeholders
• Humility, discretion, accountability, and a strong ownership mindset

Why Apex

You'll get direct exposure to the CEO and Executive Team, broad visibility across the business, and the chance to work on consequential questions while deepening your technical and commercial skills. You'll help improve how Apex evaluates opportunities and makes decisions. We offer competitive compensation, strong benefits, an entrepreneurial culture, and meaningful opportunity to contribute.
