Reservoir Engineer

Charm is looking for a Reservoir Engineer. Successful bio-oil sequestration requires a deep understanding of the reservoir: how much we can inject, at what pressure, for how long, and whether we can prove confinement and compatibility with regulators. This role owns that technical story end to end — from the reservoir engineering that tells us how our wells will behave, to the UIC permit applications that will help us bring more wells online.

This is a hands-on role for an engineer who wants to do both halves of the job. On the subsurface side, you'll build and maintain the injection strategy, reservoir models and forecasts that guide where and how we inject. On the permitting side, you'll draft and steward our Class V UIC applications — turning your own reservoir analysis into permit-ready narratives that stand up to scrutiny. Efficient permitting keeps long-term injection operations from ever being roadblocked, and doing it well requires someone who understands the subsurface deeply enough to defend it.

You'll partner closely with our subsurface, land, operations and MSE (Materials science & engineering) teams.

Working knowledge of UIC permitting (Class I, Class II and/or Class VI) — you've drafted or meaningfully contributed to permit applications, area-of-review analysis, or pressure/plume modeling narratives — or you have deep reservoir expertise and a clear appetite to build permitting into your toolkit.

A degree in petroleum or chemical engineering, or a closely related geoscience/engineering field.

5+ years of reservoir or subsurface engineering experience — injection/disposal (SWD), EOR, carbon storage, or reservoir management.

Hands-on fluency with reservoir modeling and forecasting including pressure-transient behavior, petrophysics and formation characterization.

Skills in adapting laboratory derived data into actionable optimization in the field

Strong technical writing — you can turn quantitative analysis into narratives that regulators, finance, and non-engineers can follow and trust.

Strong stakeholder and cross-functional communication skills; comfortable picking up the phone to work through a problem with a teammate, consultant, or regulator.

A proactive, organized, self-directed working style that thrives in a fast-paced startup where you'll wear multiple hats.

A demonstrated passion for contributing to our mission.

Direct experience with carbon storage or Class VI / Class V injection.

Design and interpretation of pressure-transient tests, step-rate tests, tracer surveys, or mechanical integrity tests (MIT).

Familiarity with pore space, mineral rights, well bonding, and the land/regulatory interfaces of injection projects.

Experience with reservoir simulation or subsurface software (e.g., CMG, Petrel, Kappa) and data/analytics workflows.

Prior experience in a lean or early-stage operating environment.
