Reinforcement Learning Researcher

Applied Computing was founded in 2024 to build Orbital, a physics-informed foundation model for energy operations. We’re live across oil and gas, refineries, and petrochemicals, working towards our mission: sustainable abundance for a growing planet.

The hydrocarbon industry keeps the world running. But its complexity has left operators tied to legacy systems, making critical decisions on less than 10% of available data. We built Orbital to change that. It’s a foundation model built specifically for energy that lets companies use AI at scale, harnessing all of their operational data and optimising in real time for any metric. Decisions get faster, operations get safer, and carbon intensity falls.

We’ve raised over $32 million, including one of the largest seed rounds for an AI company in the UK. We’re just getting started

How We Work

Research is judged by production impact, not paper count

We optimise for real systems, not benchmarks alone

We value safe, reliable decision-making over theoretical elegance

Physics, control, and learning are treated asone system

What This Role Is Not

Not toy RL environments (Atari,MuJoCo-only thinking)

Not unconstrainedpolicy learning without safety guarantees

Not offline research disconnected from deployment

Not a support role; this position owns core optimisation IP
