Simulation Realism Engineer (Mod/Sim) na iMETALX

Description

Company Description

iMETALX, Inc. is pioneering innovations in space accessibility and sustainability. Our mission is to deliver cutting-edge solutions in space domain awareness (SDA) and in-space servicing, assembly, and manufacturing (ISAM) to both government and commercial sectors. Our focus encompasses spacecraft autonomy, leveraging advanced technologies in perception, controls, and testing in real-world systems.

We are building a small, high-impact team working on cross-domain applications that leverage state-of-the-art computer vision, machine learning, and autonomy. This includes both space applications (ISAM & SDA) and terrestrial analogs that use similar technologies. You will be joining at a stage where your ideas and ownership meaningfully shape the technical direction, culture, and impact of the company. As a Simulation Realism Engineer, you will play a crucial role in creating robust and high-fidelity simulations that enhance our autonomy systems, critical for both space operations and terrestrial applications.

Role Overview:

We’re looking for a Simulation Realism Engineer to take ownership of high-fidelity synthetic scene generation and simulation realism at iMETALX. As a Simulation Realism Engineer at iMETALX, you will focus on designing and implementing state-of-the-art simulation environments that accurately reflect real-world scenarios for our ISAM and SDA missions. You will be responsible for enhancing simulation fidelity, minimizing the sim-to-real gap, enabling more effective testing and validation of autonomy systems, thereby pushing the boundaries of what is achievable in space operations.

Your work will involve collaborating closely with perception/ML engineers, autonomy/GNC, and customers to ensure our simulations meet rigorous performance criteria and enable meaningful insights into system behaviors under varied conditions. You will validate simulations through rigorous testing and foster innovations that lead to exciting advancements in our technology.
