ML Engineer, Surrogate Modeling; Vehicle Engineering

Position: ML Engineer, Surrogate Modeling (Vehicle Engineering)
Space

X was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today Space

X is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.

ML ENGINEER, SURROGATE MODELING (VEHICLE ENGINEERING)

Be a member of the AI for Vehicle Engineering team, focusing on developing high-performance surrogate models to solve complex phy sics and engineering problems for our launch vehicles and spacecraft.

Our team builds AI systems that accelerate engineering analysis, simulation, development, testing, avionics design, flight data review, logistics, and mission operations. Your work will directly support the world's largest communication and AI satellite constellations, accelerate rapid reuse of the Falcon launch vehicle, and contribute to the development of the world's largest rocket capable of sending humans to Mars.

In this role, you will develop, train, tune, and deploy AI surrogate models to dramatically accelerate engineering simulations, including but not limited to FEA, CFD, thermal, and structural analysis. You will work closely with hardware, simulation, and domain engineers to build these systems from the ground up. You will leverage state-of-the-art surrogate modeling techniques and create novel methodologies that push the frontier of what is possible in ML for physics while tackling real-world problems.

Aerospace experience is not required. We are looking for smart, motivated, collaborative engineers who love applying machine learning to hard scientific problems and want to make a direct impact on Space

X's mission.

RESPONSIBILITIES:

* Develop, train, evaluate, and deploy production-grade AI surrogate models that accelerate critical engineering simulation workflows

* Design and implement State-of-the-Art (SOTA) neural architectures and training strategies tailored to complex engineering problem domains

* Build scalable data pipelines to preprocess, manage, and utilize tens of thousands of high-fidelity simulation results

* Stay current with the latest research in neural operators, physics-informed ML, and surrogate modeling, implementing new techniques when needed

* Collaborate with peers on architecture, design, and code reviews

* Deep dive into engineering problems to identify where AI can deliver the highest leverage and most reliable solutions

* Develop and apply techniques for uncertainty quantification, active learning, and inverse problems (e.g., geometry and shape optimization)

* Ensure all AI systems are rigorously validated and vetted for accuracy, robustness, and reliability in engineering use

BASIC QUALIFICATIONS:

* Bachelor's degree in computer science, data science, engineering, math, physics, or a related technical discipline; OR 4+ years of professional experience building software in lieu of a degree

PREFERRED

SKILLS:

* Master's or PhD in computer science, machine learning, engineering, or a related field with a focus on surrogate modeling or AI for scientific/engineering simulation

* Demonstrated experience training, tuning, and deploying production-grade ML surrogate models in real engineering workflows

* Expert-level understanding of at least one modern architecture class such as Fourier Neural Operators (FNO), neural operators, Mesh Graph Net , Tran solver, graph neural networks, physics-informed neural networks, or other surrogate model architecture

* Experience solving inverse problems such as geometry optimization or design under uncertainty

* Strong understanding of traditional simulation and numerical methods (CFD, FEA, thermal analysis, etc) and how to integrate them with surrogate models

* Experience with uncertainty quantification techniques for surrogate models

* Hands-on experience building active learning or adaptive sampling pipelines

* Proficiency with deep learning frameworks such as PyTorch, Tensor Flow, or JAX

* Experience with surrogate modeling libraries such as NVIDIA Physics Nemo or similar

* Experience developing on Linux systems with GPU accelerators
