About Us Physics

X is a deep‑tech company with roots in numerical physics and Formula One, dedicated to accelerating hardware innovation at the speed of software. We are building an AI‑driven simulation software stack for engineering and manufacturing across advanced industries. By enabling high‑fidelity, multi‑physics simulation through AI inference across the entire engineering lifecycle, Physics

X unlocks new levels of optimization and automation in design, manufacturing, and operations. Our customers include leading innovators in Aerospace & Defense, Materials, Energy, Semiconductors, and Automotive.

• Work closely with machine learning engineers, simulation engineers, and customers to translate physics and engineering challenges into mathematical problem formulations.
• Build models to predict the behaviour of physical systems using state‑of‑the‑art machine learning and deep learning techniques.
• Own research work‑streams at different levels, depending on seniority.
• Discuss results and implications of your work with colleagues and customers, especially how these results can address real‑world problems.
• Collaborate with colleagues beyond the research team to translate your models into production‑ready code.
• Communicate your work to others internally and externally as called for in paper publication venues, industry workshops, customer conversations etc. This will involve writing for academic and non‑academic audiences.
• Foster a nurturing environment for colleagues with less experience in DS / ML / Stats for them to grow and you to mentor.

• Enthusiasm about using machine learning, especially deep learning and/or probabilistic methods, for science and engineering.
• Ability to scope and effectively deliver projects.
• Strong problem‑solving skills and the ability to analyse issues, identify causes, and recommend solutions quickly.
• Excellent collaboration and communication skills — with teams and customers alike.
• PhD in computer science, machine learning, applied statistics, mathematics, physics, engineering, or a related field, with particular expertise in any of the following:
• operator learning (neural operators), or other probabilistic methods for PDEs;
• geometric deep learning or other 3D computer vision methods for point‑cloud or mesh‑structured data;
• generative models for geometry and spatiotemporal data (VAEs, Diffusion Models, Bayesian non‑parametric, scaling to large datasets, etc.).
• More than 2 years of experience in a data‑driven role in a professional industry setting (excluding post‑doc positions), with exposure to building machine learning models and pipelines in Python, using common libraries and frameworks (Num Py, Sci Py, Pandas, PyTorch, JAX), especially including deep learning applications; developing models for bespoke problem settings that involve high‑dimensional data; iterating on network architectures and model structure, tuning and optimising for inductive biases, improved generalisability, and improved performance;
  
  combining theoretical reasoning with empirical intuition to guide investigation; formulating and running experiment pipelines to benchmark models and produce comparable results; writing skills for communication complex technical concepts to peers and non‑peers.
• Publication record in reputable venues that demonstrates mastery in your field, and in particular the domains of interest listed above. Desirable venues include NeurIPS, ICML, ICLR, UAI, AISTATS, AAAI, Siggraph, CVPR or TPAMI/JMLR.

• Build what actually matters: help shape an AI‑native engineering company at a formative stage, tackling problems that genuinely matter for industry and society.
• Learn alongside exceptional people: work with a high‑caliber, collaborative team of engineers, scientists, and operators who care deeply about doing great work.
• Influence over hierarchy: we operate with a flat structure where good ideas win.
• Sustainable pace, long‑term ambition: building meaningful technology is a marathon, not a sprint.
• Equity options to share meaningfully in the company.
• 10% employer pension contribution.
• Free office lunches.
• Enhanced parental leave: 3 months full pay…
