About the role

Reservoir Simulation Engineer role at UniversalAGI focusing on building high-fidelity reservoir simulation data to train AI foundation models for subsurface flow, collaborating directly with executives and AI team, and solving real customer problems.

Responsibilities

  • Design, build, and run reservoir simulation studies, both blackoil and compositional models, across conventional and unconventional reservoirs, at unprecedented scale and speed
  • Develop creative reservoir models and simulate hundreds or thousands of variants, building data pipelines for training foundation models
  • Bridge reservoir engineering and AI: work on research problems with the AI team to connect traditional simulation with ML
  • Collaborate with clients to define benchmark datasets, validation criteria, and workflows that prove model accuracy
  • Generate high-quality simulation data at scale to improve foundation models
  • Advise AI research on PVT behavior, relative permeability, capillary pressure, history matching, uncertainty quantification, multi-stage hydraulic fracturing, fracture networks, and production-decline behavior
  • Lead technical customer conversations translating reservoir engineering to AI context

Qualifications

  • 3-5+ years of industry hands-on experience building and running reservoir simulation models, including conventional (blackoil and compositional) and unconventional reservoirs, from model construction through history matching, forecasting, and optimizing field development
  • Expert in reservoir simulation frameworks (Eclipse/Intersect, CMG, OPM Flow, or similar), including blackoil and compositional formulations
  • Deep understanding of reservoir engineering fundamentals: PVT behavior, relative permeability and capillary pressure, well modeling, material balance, and history matching
  • Solid understanding of the static-to-dynamic model handoff: geologic and geocellular model construction, upscaling, and grid generation
  • Strong communicator capable of bridging customers, engineering and research teams
  • Outstanding execution velocity and delivery
  • Exceptional creativity, problem-solving ability, ambition, and attention to detail
  • Comfortable working in high-intensity, fast-paced startup environments with evolving priorities and tight deadlines
