AI in this role

Build and scale massive simulation environments and physics engines to train reinforcement learning superintelligence agents.

Our mission is to make first contact with superintelligence.

We are creating a superlearner that discovers all knowledge from its own experience, from elementary motor skills through to profound intellectual breakthroughs. This superlearning capability - the ability to endlessly discover knowledge and skills, without relying on human data - will be driven by the world’s most powerful reinforcement learning algorithms.

The superlearner is expected to rediscover and then transcend the greatest inventions in human history, such as language, science, mathematics and technology. If successful, this will represent a scientific breakthrough of comparable magnitude to Darwin: where his law explained all life, our law will explain and build all intelligence.

Role brief

Intelligence cannot emerge in a void. It needs a place to grow and flourish. As an Engineer for Simulated Universes, you’ll help us craft, shape and maintain the worlds in which superlearners can emerge and thrive. That means making those worlds accurate, reliable and intricate, and scaling them to unprecedented highs in terms of both parallelism and speed. It’s a challenging quest and one that’s critical to our mission. In this role, you will:

  • Build the engineering foundations of our new environments; designing, implementing and maintaining them as they grow

  • Partner closely with the team creating the blueprints for the worlds we need to build

  • Close the loop between blueprint and build, enabling fast, iterative research cycles

  • Scale the environments up, while utilising state-of-the-art hardware

About you

You’re an engineer with a passion for creating artificial worlds, and you know what it takes to make them emerge at scale. You may be a good fit if you:

  • Bring industry experience with large-scale simulations, whether in demanding scientific domains or in the games industry

  • Know how to build systems like huge distributed MMOs that rely on world parallelism, large-scale physics engines, or logic that preserves consistency despite decentralised computation

  • Turn ambitious research visions into reality by designing, building and maintaining codebases that support fast research iteration and efficient execution

  • Enjoy working closely with researchers and/or "designers", taking their blueprints and turning them into worlds that agents can explore and learn

On the pure engineering side, you’ll likely have experience with the following:

  • Physics engines

  • GPU-accelerated physics and simulation frameworks, such as NVIDIA Warp

  • Lower level languages such as Rust, C or C++

  • Implementation of distributed server-client architectures

  • Writing efficient GPU code

 

We move fast, give people real ownership and trust engineers to make good judgment calls. We are a team that cares as much about doing this well as doing it fast.

Questions you could be asked

  1. Tell me about a project where simulation was part of your work. What did you do?
  2. Tell me about a project where reinforcement learning was part of your work. What did you do?
  3. Tell me about a project where distributed systems was part of your work. What did you do?
  4. Tell me about a project where c was part of your work. What did you do?

Adapt your resume

  • List these exact terms on your resume: Simulation, Reinforcement Learning, Distributed Systems, C, and Python. An applicant tracking system matches the wording, not the idea.
  • Attach one line of real, concrete experience to at least one of them — a tool named with nothing behind it rarely survives a human read.
  • Lead with what you built, trained or shipped — this role is judged on the AI system itself, not the tools around it.
