Founding Simulation Engineer


Trekion builds simulation infrastructure for robotics teams, enabling them to build trustable simulations to train and evaluate their policies against. We are building real2sim2real pipelines that match simulation to reality.

As a founding simulation engineer you will own large parts of this pipeline from day one, working directly with customers and real hardware. This is an early role with a lot of ownership: you decide how the pipeline is built and validated.

What you will do

  • Partner directly with customers to understand their robots, products, sensors, actuators, and sites, and turn incomplete specs and messy data into simulation artifacts.

  • Run hands-on simulation, calibration, and system identification work. Build and calibrate sensor and actuator models, tune contact and dynamics against measurements from the physical system, and use system identification to fit simulation parameters from real data.

  • Develop metrics and validation methods to understand the sim2real gap, and improve upon them.

  • Model complex environments and assets in simulation, including articulated and deformable assets where the customer's task needs them.

  • Build pipelines around simulation for data generation, evaluation, and continual improvement.

Who you are

  • Hands-on experience with robots and simulators. If you have had your hands dirty building robots both in real life and in sim, and understood the pain of transferring policies from sim to real, you are the right fit for us.

  • A record of taking something from idea to a working system on real hardware or real data, not only a prototype.

  • You have high agency and high integrity, and you are willing to learn, apply, and fail quickly.

  • You take complete ownership with minimal guidance and do everything possible to make the product work.

  • It does not matter if you do not have the relevant experience in any of the requirements, as long as you have a strong interest to learn and apply quickly.

Nice to have

  • Experience with at least one of Isaac Sim, MuJoCo, or Genesis.

  • Strong Python skills for data analysis, automation, and similar work.

  • ROS2 and other basic robotics skills.

  • 3D reconstruction techniques, such as Gaussian splatting.

How to apply

Send us a link to something that you have built and are proud of, out of your own interest, and anything you want us to know about you that will help you stand out, to careers@trekion.ai.
