Reservoir Simulation Engineer

Who We Are

Engineering simulation is one of the last major categories of software that AI hasn't rebuilt. The tools used to simulate aircraft, ships, reservoirs, and medical devices still run on numerical methods that are decades old, and an engineer can wait a full day for a single answer. UniversalAGI is building foundation models that learn physics directly from data, and they are already running in early deployments on real computational fluid dynamics and reservoir engineering problems for some of the largest industrial and defense organizations in the world.

We are a team of 25 researchers and engineers in San Francisco backed by Elad Gil (#1 Solo VC), Eric Schmidt (former Google CEO), Ion Stoica (Databricks Founder), Jared Kushner (former Senior Advisor to the President), David Patterson (Turing Award Winner), and Luis Videgaray (former Foreign and Finance Minister of Mexico).

About the Role

As a Reservoir Simulation Engineer, you'll be in the arena from day one, building the future of AI for physics simulation with your own hands. This is your chance to take everything you've learned building, running, and history-matching reservoir models, conventional and unconventional alike, and use it to generate the high-fidelity simulation data that trains our foundation models for subsurface flow.

You'll work directly with the CEO and founding team to shape our product around the real pain points you've faced in your career: the weeks lost building and history-matching reservoir models, the manual handoff between geologic modeling and dynamic simulation, and the limits of a single deterministic forecast when the subsurface is anything but certain.

What You'll Do

• Design, build, and run reservoir simulation studies, both blackoil and compositional models, across conventional and unconventional reservoirs, at unprecedented scale and speed
• Come up with creative ways to construct reservoir models, simulate hundreds or thousands of reservoir model variants systematically, building the data pipelines that will train our foundation models
• Guide the development of our product and our revolutionary new AI models for physics by working directly on research problems with our AI team, bridging the gap between traditional reservoir simulation and cutting-edge ML
• Work directly with clients to solve their problems and define benchmark datasets, validation criteria, and workflows that prove our models can match or exceed traditional reservoir simulation accuracy
• Generate high-quality simulation data at scale; every simulation you run directly improves our foundation models
• Advise the AI research team on the nuances that matter: PVT behavior and fluid characterization, relative permeability and capillary pressure, history matching and uncertainty quantification, multi-stage hydraulic fract

How We’re Different

“The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again... who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly." - Teddy Roosevelt

At our core, we believe in being “in the arena.” We are builders, problem solvers, and risk-takers who show up every day ready to put in the work: to sweat, to struggle, and to push past our limits. We know that real progress comes with missteps, iteration, and resilience. We embrace that journey fully knowing that daring greatly is the only way to create something truly meaningful.

If you're ready to join the future of physics simulation, push creative boundaries, and deliver impact, UniversalAGI is the place for you.
