About The Role
Peabody is seeking a technically strong Underground Gas Modelling Engineer to support our underground coal operations across Australia and the United States. This role is centred on coal seam gas (CSG) modelling, gas drainage design, and methane management, providing critical inputs into safe mine design, operational performance, and Life of Mine planning.
The position has a primary focus on gas reservoir modelling and drainage optimisation within underground coal environments. Experience in underground ventilation modelling is considered advantageous but not essential.
Given the specialised nature of this capability, we are also open to candidates from research or academic backgrounds who bring advanced modelling expertise and the ability to translate theory into practical mining outcomes.
Reporting to the Director, Underground Mining Engineering, you will partner closely with Technical Services, mine planning, geology, HSE, and site operations to embed data‐driven gas management strategies across the portfolio.
Key Responsibilities
Develop, calibrate, and maintain CSG reservoir and gas drainage models to assess gas quality, quantity, and flow behaviour within underground coal seams
Lead modelling to inform gas drainage strategy, SIS/UIS design, and methane management frameworks
Conduct advanced simulations to support pre‐drainage, post‐drainage, and in‐seam gas capture programs
Translate modelling outputs into practical drilling programs, infrastructure requirements, and operational plans
Support gas capture, utilisation, flaring, and destruction strategies, including evaluation of commercial opportunities
Partner with mine sites and external providers to optimise gas drainage performance and execution
Provide technical input into mine planning, feasibility studies, and Life of Mine strategies
Prepare and support CSG Statements, regulatory submissions, and environmental documentation




Collaborate with geology and planning teams to integrate subsurface data into modelling frameworks
Support troubleshooting and continuous improvement of gas performance across operations
Qualifications
Bachelor's degree in Mining, Petroleum, Geological, or related Engineering discipline
Strong capability in reservoir modelling, numerical simulation, or subsurface modelling
Experience with relevant modelling tools (e.g., reservoir simulation or gas drainage software)
Exposure to underground coal mining environments will be highly regarded
RPEQ / Chartered Engineer status (or working towards) is desirable
Experience
Minimum 5 years' experience in gas modelling, reservoir engineering, or underground coal gas management
Demonstrated capability in CSG evaluation, gas drainage design, and modelling‐driven decision making
Experience translating complex modelling outputs into operationally practical solutions
Background in underground coal is strongly preferred, however we will consider adjacent industries or research backgrounds with transferable modelling expertise
Exposure to ventilation modelling (e.g., Ventsim) is considered beneficial but not required
The Lifestyle
This position is based in the Fortitude Valley office on a Monday–Friday roster, with flexible work‐from‐home options. Versatile start and finish times and the redistributed working week give employees the option to finish at noon on Fridays. Occasional site travel to Queensland and New South Wales operations will be required.
