1.3 Physics-Informed ML Engineer : Model Architectures

Job Description

Job Description

Field AI is transforming how robots interact with the real world. We are building risk-aware, reliable, and field-ready AI systems that address the most complex challenges in robotics, unlocking the full potential of embodied intelligence. We go beyond typical data-driven approaches or pure transformer-based architectures, and are charting a new course, with already-globally-deployed solutions delivering real-world results and rapidly improving models through real-field applications.

We are seeking a Physics-Informed Machine Learning (PIML) Engineer to join our innovative team focused on advancing risk-aware, autonomous systems. This role blends cutting-edge machine learning techniques with a strong foundation in physics, with an emphasis on safety, uncertainty quantification, and system robustness in real-world applications. The ideal candidate will work on integrating physical laws and constraints into machine learning models to create systems that learn from fewer data points while maintaining high accuracy and reliability in critical environments.

What You Will Get To Do

• Develop hybrid physics-ML models that combine theoretical physics-based components with data-driven elements to create more accurate and generalizable robotics autonomy solutions
• Design physics-informed architectures (e.g., physics-informed neural networks or universal differential equations) to solve complex robotic systems while respecting physical constraints like conservation of momentum, contact dynamics, and joint limits
• Lead research initiatives in physics-informed learning for robot control , combining model-based and model-free approaches, solving forward and inverse problems in robotic systems using PIML
• Create discrepancy models to bridge theoretical physics models with empirical data, analyzing the convergence, generalization, and error estimation of PIML models, ensuring stability and robustness in deployment.
• Design and evaluate novel neural network architectures that respect physical laws and constraints
• Build and optimize differentiable simulation pipelines for robot trajectory and control policy optimization, addressing complex physical constraints such as uncertainty in perception systems .
• Develop uncertainty-aware models combining physical knowledge with probabilistic state estimation (e.g., SDEs, Bayesian inference) for improved perception and intelligence.
• Implement multi-scale modeling and domain decomposition to address large-scale challenges in autonomous robotics.
• Collaborate with robotics teams to deploy physics-informed models in real-world autonomous systems.
• Publish research in physics-informed machine learning and hybrid modeling for robotic systems.

What You Have

Compensation and Benefits

Our salary range is between ($70,000 - $200,000 annual), but we take into consideration an individual's background and experience in determining final salary; base pay offered may vary considerably depending on geographic location, job-related knowledge, skills, and experience.  Also, while we enjoy being together on-site, we are open to exploring a hybrid or remote option.

Why Join Field AI?

We are solving one of the world’s most complex challenges : deploying robots in unstructured, previously unknown environments. Our Field Foundational Models™ set a new standard in perception, planning, localization, and manipulation, ensuring our approach is explainable and safe for deployment.

You will have the opportunity to work with a world-class team that thrives on creativity, resilience, and bold thinking. With a decade-long track record of deploying solutions in the field, winning DARPA challenge segments, and bringing expertise from organizations like DeepMind, NASA JPL, Boston Dynamics, NVIDIA, Amazon, Tesla Autopilot, Cruise Self-Driving, Zoox, Toyota Research Institute, and SpaceX, we are set to achieve our ambitious goals.

Be Part of the Next Robotics Revolution

To tackle such ambitious challenges, we need a team as unique as our vision — innovators who go beyond conventional methods and are eager to tackle tough, uncharted questions. We’re seeking individuals who challenge the status quo, dive into uncharted territory, and bring interdisciplinary expertise. Our team requires not only top AI talent but also exceptional software developers, engineers, product designers, field deployment experts, and communicators.

We are headquartered in always-sunny Mission Viejo (Irvine adjacent), Southern California and have US based and global teammates.

Join us, shape the future, and be part of a fun, close-knit team on an exciting journey!

We celebrate diversity and are committed to creating an inclusive environment for all employees. Candidates and employees are always evaluated based on merit, qualifications, and performance. We will never discriminate on the basis of race, color, gender, national origin, ethnicity, veteran status, disability status, age, sexual orientation, gender identity, marital status, mental or physical disability, or any other legally protected status.
